Interview Questions.

Question 1. Why Are Landscapes Irrigated?

Answer :

Simply said, irrigation gives the water necessities for sustainability of plant life while rainfall is not sufficient.

Ornamentals: Trees and shrubs are irrigated frequently whilst grown inside the nursery and whilst first planted so that their roots quick develop out from the basis ball and into the soil in the landscape. It is important that roots develop as fast as viable so irrigation can cease. The satisfactory manner to inspire rapid root boom is common mild irrigation carried out to the foundation ball after planting. Under perfect conditions (e.G., in non-compacted soils, surrounded by means of tremendous irrigated regions), many Florida-Friendly plants do now not require further irrigation except in extended drought.

Turf: Although Florida receives sizeable rainfall, dry durations are not unusual inside the overdue spring and fall. The dry period in the spring coincides with peak plant water wishes because of growing temperatures, solar radiation, and day duration. Due to particularly shallow roots, turfgrasses usually require irrigation as a minimum as soon as per week to hold excellent. On sandy soils, some grasses may additionally want to be irrigated as a minimum two days a week to ensure perfect pleasant (Shedd et al., 2008).

Question 2. What Are The Irrigation Requirements For Turfgrass And Landscape Plants?

Answer :

Note: The term “irrigation necessities” implies nicely-watered situations, because of this that this is the quantity of irrigation water further to effective rainfall (that that is stored in the plant root zone and to be had to be used) wished for plant growth and without any water strain.

Ornamentals: All panorama shrubs and trees grown in a nursery and planted in a panorama require water to come to be established. Under most instances, rainfall happens irregularly, so irrigation is required, at least till flora are established. Trees require approximately 3 to 4 months according to inch of caliper (trunk diameter measured 6" from floor) to emerge as installed. Shrubs require approximately 20 to 28 weeks to come to be installed. Irrigation occasions must be 2 to 3 gallons of water consistent with inch trunk diameter. For instance, a 2-inch tree must be watered 4 to 6 gallons at every irrigation event. Water every other day till vegetation are mounted.

In addition to initial watering for establishment, irrigation in the year following establishment may be needed to hold top nice in dry weather. We have little facts on irrigation necessities for flora as soon as set up, due to the many factors that affect this. These factors consist of slope, factor, soil compaction, soil intensity, soil extent, width of soil space, depth to water desk, wind, season, length of plant at planting, nursery production approach, duration of time inside the field, and root pruning techniques at planting. This research virtually has no longer been done.

Turf: Under properly-watered conditions, Stewart and Mills (1967) said that annual water consumption in South Florida for St. Augustinegrass and bermudagrass averaged 43 inches/12 months over 5 years. For North Florida, Jia et al. (2007) stated 33 inches of overall water necessities for bahiagrass. Irrigation necessities for turfgrass in North Florida are on the order of 20–25 inches/year and 30–35 inches/year in South Florida, on common (Smajstrla, 1990). These numbers are internet irrigation necessities and do not consist of introduced irrigation because of the inefficiency inherent in all irrigation systems. See “Efficiencies of Florida Agricultural Irrigation Systems, ” for greater information on irrigation performance (Smajstrla et al., 1991). In most years, rainfall will make contributions extensively to assembly the entire water call for of turfgrasses.

Question three. Do Different Varieties Of Turfgrasses Use Different Amounts Of Water?

Answer :

Many research were conducted on water use of turfgrasses. Most of those studies are carried out beneath “nicely-watered” situations (i.E., no strain because of lack of water) and must no longer be pressured with drought studies where water is withheld and physiological responses of grasses are studied.

All turfgrasses need water to sustain accurate first-class (dense, uniform, inexperienced), whether it comes from rainfall or supplemental irrigation. Drought-tolerant grasses will go into dormancy throughout dry periods, developing greater slowly or turning brown until conditions are favorable for increase. When sufficient soil moisture returns, these grasses can generally recover from drought-caused dormancy in place of demise. For example, bahiagrass is drought-tolerant, however if it isn't furnished with good enough water, the drought response of this grass will result in dormancy and a “useless” look.

Much of the literature seems to suggest that there may be variations in water use between one-of-a-kind warm-season grasses. These disparities probably stem from herbal variations in mowing heights (e.G., St. Augustinegrass lawns as opposed to bermudagrass golf turf), fertility, leaf structure, etc. However, these variations have no longer been simply documented in Florida work.

In one have a look at, Zazueta et al. (1999) located that when maintained beneath UF/IFAS recommendations, bahiagrass had 11 percent better water use quotes than St. Augustinegrass whilst nicely-watered, but that the 2 grasses had comparable transpiration costs while underneath continual stress. A present day UF/IFAS have a look at is exploring the water use quotes, under properly-watered situations, of several grasses together with St. Augustinegrass and bahiagrass.

Question four. Do Natives Require Less Water? If So, When?

Answer :

A plant's indigenous popularity does now not affect its fertilizer or irrigation necessities. There isn't any scientific evidence that local plant life require much less fertilizer and water than flowers no longer local to Florida. To placed it some other way, residential and business landscapes are regularly very special from the local situations wherein a plant originated, even supposing they're observed inside the same nation. Additionally, a plant that become previously indigenous to a domain might not be adapted to the place any further, depending at the way the web site has been altered. In a latest studies examine, Florida local shrubs required the equal irrigation as non-natives (Scheiber et al., 2007). Fertilizer necessities have now not been examined.

Question five. Will Planting Another Type Of Turfgrass Automatically Result In Water Savings?

Answer :

The clinical proof seems to point to human behavior with reference to over-irrigation—not specific plant life within the panorama—because the purpose for tons wasted irrigation water. In addition, there's some proof that during well-watered (i.E., sustained proper first-class) situations, bahiagrass makes use of barely greater water than St. Augustinegrass. Thus, replacing St. Augustinegrass with bahiagrass will not in all likelihood reduce water wishes for well-watered conditions. In addition to water, there are numerous other factors, which include renovation level, illnesses, and pests, that want to be taken into consideration associated with a turfgrass change.

Land Surveyor Interview Questions
Question 6. What Is The Proper Way To Irrigate?

Answer :

Scientifically, irrigation have to occur based totally on plant reaction to environmental demand. Thus, irrigation frequency and quantity can be described by using the environmental call for (i.E., evapotranspiration, ET), soil water-retaining ability and plant root zone intensity. Irrigation should be applied such that the soil water reservoir is filled and gravity drainage and runoff do now not arise. This approach is designated in an EDIS guide entitled, “Basic Irrigation Scheduling in Florida,” (Smajstrla et al., 2006), which presents precis statistics from the world over diagnosed publications which includes “Crop evapotranspiration: Guidelines for computing crop water requirements” (Allen et al., 1998). This scientifically commonplace approach ambitions to result in “properly-watered” situations where no stress is allowed. In addition, an irrigation machine should be nicely-designed and in good repair to use irrigation successfully to vegetation (i.E., without losses due to runoff and deep percolation).

In exercise, irrigation is often restricted to precise days of the week with the aid of water management districts via most of Florida. Thus, panorama plant life may go through various levels of strain depending on precise site conditions and plant type.

Ornamentals: In the case of newly planted timber and shrubs, water should be applied to the root ball and perhaps the soil just past the basis ball. In all of the research during the last twenty- years on trees in Florida, the place past the basis ball has not been irrigated. Trees and shrubs set up just high-quality without vast, panorama-wide (i.E. Sprinkler) irrigation. For example, live o.K.And southern magnolia tree root systems enlarge to approximately 14–20 toes in diameter twelve months after planting in a non-compacted soil with out interference from curbs, sidewalks and different soil obstructions.

Turf: Guidelines for turf irrigation encompass an irrigation machine that is nicely designed and in excellent repair. Generally, UF/IFAS irrigation hints propose irrigation of ½–¾ inches whilst 30–50 percent of turfgrass shows signs and symptoms of wilt at some point of the day. However, if an automatic irrigation gadget is used beneath day-of-the-week water regulations, software run time pointers are given in “Operation of Residential Irrigation Controllers.” The pointers in this booklet have been in addition subtle into user-pleasant pointers and posted as the FAWN urban irrigation scheduler.

Question 7. Are The Terms “drought-tolerant” And “irrigation Requirement” Related?

Answer :

Physiologically, tolerance manner that the organism tolerates the strain without struggling major harm or is able to maintain to characteristic in a strain-induced country. Plants might also do this via drought avoidance, physiological adaptations that have enough money tolerance, or through performance mechanisms. Drought avoidance may be escape, together with a plant that reproduces fast, thereby heading off drought, or via conservation mechanisms together with stomatal closure, change in leaf cover or orientation, or cuticular resistance. They may also keep away from drought through growing an extensive root gadget.

Physiological adaptations may also encompass osmotic adjustment, changes in cellular elasticity, and dessication tolerant enzymes, all of which help the plant maintain turgor. Efficiency mechanisms include high water use performance (WUE). WUE is regularly described as growth in line with devices water provided, photosynthesis per devices water, and so forth. Mechanisms that beautify drought tolerance lessen WUE because boom and carbon assimilation are decreased by using leaf firing, rolling, and so forth.

It is essential to be aware that any plant would require common irrigation after planting to make certain survival and established order. For established flowers, the irrigation requirement is described as the water needed, unique of rainfall, for a crop to develop with out water strain. It is the distinction between ET (evapotranspiration or plant water use) and rainfall. ET may be calculated the use of one in all a number of models, all of that have inherent uncertainty. Using climatological information, you can estimate ET and for this reason calculate the irrigation requirement on a monthly or annual foundation as the distinction between ET and powerful rainfall. Effective rainfall is rainfall that is predicted to remain within the root zone of the plant. Effective rainfall is the result of total rainfall minus losses to drainage and percolation under the root sector.

Ornamentals: Once drought-tolerant vegetation, like live okayand burford holly, are hooked up, they are able to resist prolonged dry periods with little or no irrigation.

Turf: All of our grasses in Florida use one of a kind mechanisms to enter dormancy all through drought pressure (leaf firing, rolling, and so forth.). This metabolic resting nation lets in them to continue to exist the strain and some of them to resume boom after conditions once more become favorable.

Land use Planning Interview Questions
Question eight. Can Reclaimed Water Be Used For Irrigation?

Answer :

Yes, reclaimed water may be and is used for irrigation. In reality, Florida is a pacesetter in the U.S. Within the use of reclaimed water for irrigation, with approximately 660 million gallons of reclaimed water getting used every day, in line with the Florida Department of Environmental Protection 2006 Reuse Inventory.

Reclaimed water does generally contain increased stages of salts relative to Florida floor and groundwater, besides wherein saltwater intrusion is elaborate in coastal areas. The improved stages of salts in reclaimed water may also effect specific plant species in varying ways because of differences in salt tolerance. Periodic testing of reclaimed water utilized in irrigation is suggested.

Also, reclaimed water can also include plant nutrients, which may additionally need to be taken into consideration in any fertility program. It isn't always clear that all the nutrients in reclaimed water are to be had for plants. Finally, the content material of reclaimed irrigation water can range between different municipalities due to allowing differences and unique variations between wastewater remedy vegetation. 

Question nine. Is There A Correlation Between Plant Water Need And Homeowner Water Use?

Answer :

Haley et al. (2007) showed that house owners did use considerably much less water inside the iciness than different seasons. However, universal house owners over-watered as plenty as 2–3 times the quantity needed by using the flowers, based totally on estimates of climate demand. Thus, there may be some indication that house owners lessen irrigation at some point of intervals when less is wanted; however, it appears that over-irrigation may also still occur.

Landscape Interview Questions
Question 10. Are Day-of-the-week Restrictions Effective At Reducing Water Use?

Answer :

In a word, yes, however most effective if they're enforced. Over time, their effectiveness can become reduced. Olmsted (2008) reviewed the literature to determine the effectiveness of day-of-the-week watering restrictions precise to Florida. In Hillsborough and Orange Counties, water use reductions (by using utilities) were pronounced as 17–18 percentage; but, no discounts had been seen in Seminole County. In South Florida, day-of-the-week regulations decreased water burn up to 21.5 percentage all through in the future/week watering restrictions.

Day-of-the-week regulations restrict flexibility for users who attempt to plan irrigation based on rainfall traits. In addition, they'll encourage over-watering on the allowed day. Just due to the fact potable water demands decrease beneath regulations, it would not suggest that irrigation is being applied at the proper time and inside the right quantity—in other phrases, it is feasible that water remains being wasted, despite the fact that it may be a smaller quantity. However, to a large extent, many panorama vegetation can survive for the duration of maximum intervals of water restriction.

Question 11. Are There Uf/ifas Recommendations For Irrigation, And, If Followed, Do They Provide Water Conservation Benefits?

Answer :

Ornamentals: Irrigation pointers for timber can be observed at http://hort.Ufl.Edu/woody/. There isn't any documentation of how many people follow them. It could be difficult to record the effect of particular practices on decorative plant fabric, because these materials handiest make up a part of the planted panorama in most instances. Further, in many irrigation systems, turfgrass and ornamentals and trees aren't separated in phrases of irrigation zones and for this reason acquire the equal quantity of irrigation relative to the gadget programming.

Turf: UF/IFAS recommends watering whilst 30–50 percent of turfgrass wilts. This must provide water conservation advantages relative to “set it and neglect it” time clock programming; however, this has no longer been documented.

Haley et al. (2007) confirmed that the usage of the time table endorsed in “Operation of Residential Irrigation Controllers ” decreased watering through 30 percent over a thirty-month observe. Thus, if this recommendation have been observed, widespread water savings are possible for slight to high irrigators. The “FAWN urban irrigation scheduler " uses those guidelines in a consumer-friendly style to inspire customers to adjust irrigation time clocks to better modify for climatic demand during the year.

WASH Officer (Water, Sanitation, and Hygiene) Interview Questions
Question 12. Which Turfgrasses And Landscape Plants Can Be Grown Without Supplemental Irrigation Or Fertilization?

Answer :

Some turf species might not need water to survive, however all need water to live inexperienced. Drought tolerance implies that the grasses will “fire” (turn brown) and reduce leaf place to preserve water. Some, which includes bahiagrass or centipedegrass, will showcase better healing from drought strain. St. Augustinegrass and most of the zoysiagrass types will now not usually persist nicely without supplemental irrigation throughout times of confined rainfall. Fertilization follows a comparable fashion—bahiagrass and centipedegrass have low fertilization requirements and may keep on with surprisingly low stages of vitamins.

Question 13. What Are The Mechanisms Available To Reduce Over-watering Right Now On Existing Irrigation Systems In Landscapes? How Effective Are These Mechanisms?

Answer :

Florida statute 373.62 mandates the installation of a running rain sensor device or activate all computerized irrigation systems mounted due to the fact 1991. UF/IFAS studies has proven that increasing disk rain sensors may be effective at conserving water. Potential financial savings of 17 to 34 percent had been proven at ½-inch and ¼-inch thresholds under regular rainfall frequencies (Cardenas-Lailhacar & Dukes, 2008; Cardenas-Lailhacar et al., 2008).

Ornamentals: In 22 years of irrigation research on timber and shrubs, only drip irrigation and different low-quantity irrigation gadgets were used. These devices have allowed little or no water software while maintaining plant great, even though there are troubles with pests such as squirrels chewing thru the traces, causing protection problems.

Turf: Cardenas-Lailhacar et al. (2008) showed that era which include soil moisture irrigation controllers can lessen irrigation by 70–90 percentage for a range of merchandise and irrigation watering days without negatively impacting turf great throughout normal rainfall situations. Further paintings with well set up soil moisture sensor irrigation controllers on houses in Florida suggests the capability for 50 percentage irrigation savings without a poor effect on panorama great (Haley & Dukes, 2007). Similar savings appear viable with different “clever irrigation” controllers together with ET controllers.

Question 14. What Is Drip Irrigation?

Answer :

Drip irrigation is the manner of handing over particular quantities of water and vitamins at once to the plant's root area, drop via drop, supplying growers actual irrigation manage and green use of constrained water sources.

Question 15. Why Should I Use Drip Irrigation?

Answer :

Slow even flow of water to plants and soil: Shrubs and flowers will thrive. Application of water and nutrients at once to the plant's roots is the pleasant manner to ensure plant fitness and power.

Easy to put in - flexible and daptable: Dripperline installs easily in tight, awkwardly formed areas which are tough to water with conventional spray structures.

Solves spray irrigation: troubles No damaging spray on buildings, windows, fencing, or pedestrians in excessive traffic areas.   Avoids unpleasant brown spots on roses and other flowers, since spray by no means touches the plants. Soil and foliage are stored dry, lowering fungal diseases.

Improved plant boom: Makes vegetation fuller and more healthy. Water and nutrients added at once to the root area promotes wholesome plant growth and decreases plant stress. Soil aeration is improved because soil particles aren't washed down, decreasing soil compaction and improving root growth.

Saves on protection & labor: No shifting sprinkler components to have to restore.  Installs with far less labor than sprinklers. 

Unobtrusive & aesthetic: Hidden and lying near the plant, coloured  Brown. Doesn't interfere with landscaping or surroundings.

Security: No exposed sprinkler heads, pipes or floor dripperlines to ride on or tamper with.

Question 20. What Is Sprinkler Irrigation?

Answer :

Sprinkler Irrigation is a method of making use of irrigation water that's just like rainfall. Water is sent thru a gadget of pipes commonly by means of pumping. It is then sprayed into the air and irrigated entire soil floor through spray heads in order that it breaks up into small water drops which fall to the ground.

Sprinklers offer efficient insurance for small to massive regions and are appropriate for use on all forms of properties. It is likewise adaptable to nearly all irrigable soils on the grounds that sprinklers are available in a huge range of discharge capacity.

Solar Water Pumps Interview Questions
Question 21. What Is Microirrigation System?

Answer :

Microirrigation is common software of water immediately on or below the soil surface close to the basis quarter of vegetation. It supplies required and measured quantity of water in distinctly small quantities slowly to the character or corporations of flowers. Water is applied as continuous drops, tiny streams, or high-quality spray through emitters placed alongside a low-stress delivery system. Such machine offers water exactly to plant root zones and keeps perfect moisture conditions for plant growths.

Question 22. Types Of Microirrigation System?

Answer :

The fundamental sorts of microirrigation gadget are as follows:

Surface System: It is the gadget wherein emitters and laterals are laid on the ground surface alongside the rows of plants. The emitting gadgets are located inside the root quarter place of bushes.

Sub-surface System: It is a device wherein water is applied slowly under the land floor through emitters. Such structures are commonly desired in semi everlasting/permanent installations.

Bubbler device:  In this system the water is implemented to the soil surface in a small stream or fountain. Bubbler structures do not require intricate filtration systems. These are suitable in situations wherein large amount of water want to be carried out in a short period of time and appropriate for irrigating bushes with extensive root zones and excessive water requirements.

Micro and mini Sprinklers: These are small plastic sprinklers with rotating spinners. The spinners rotate with water pressure and sprinkle the water. These are to be had in special discharges and diameters of insurance and might perform at low stress inside the range of one.0 to 2kg/cm2. Water is given only to the root area area as in the case of drip irrigation however now not to the whole ground floor as executed inside the case of sprinkler irrigation technique.

Pulse:  Pulse gadget uses excessive discharge rate emitters and consequently has short water utility time.  The primary gain of this device is a likely discount in the clogging hassle.

Biwall: It is extruded twin chamber micro-irrigation tubing product of Linear Low Density Polyethylene (LLDPE). This machine is suitable for all carefully spaced row vegetation like sugarcane, cotton, veggies, onion, tea and many others.

Question 23. How About Those Tight Or Awkwardly Shaped Areas That Are Difficult To Water With Conventional Spray Systems?

Answer :

Dripper lines solve the problem and avoid spraying your walls, window and fences. Consistent watering with dripper strains helps establish and shield new shrub beds and planting areas.

Piping Design Engineer Interview Questions
Question 24. Can I Save Money Using Drip Irrigation Vs. Traditional Spray Sprinklers?

Answer :

To help the minimize liability and vandalism and saves your customers' charges associated with persisted upkeep and water usage.  A easy shrub bed set up is short and easy, both buried four" below the surface or beneath mulch.

Land use Planning Interview Questions
Question 25. What About Different Soil Types? Even Clay?

Answer :

Subsurface irrigation works better in heavy clay or sand situations than traditional sprinkler systems. Even "heavy clay" and "sandy" soils are a aggregate sand, silt and clay. Loam, which contains same proportions of sand, silt and clay, is good. However, vegetation can thrive in a very broad spectrum of soil textures while subsurface watering is applied on the proper price, with suitable spacing. Different soils create ordinary wetting sample sun shades as visible at proper. Note the dramatic overlap making sure total insurance in the course of varying root quarter depths.

Drip irrigation works extremely good in clay soils. What most of the people regard as "heavy clay" and "sandy" soils are definitely mixtures of sand, silt and clay with a view to allow for ok water motion and retention between soil particles.

Question 26. Does Water Only Move Downward, Pulled By Gravity?

Answer :

When applied slowly (as in drip irrigation) water radiates outward from its supply point, growing an overlapping wetting pattern under the floor. See the "wetted pattern" instance" at right. When carried out slowly to the soil at a single factor, water movements thru the soil in  ways: 

Downward pulled by way of gravity. 
Outward and upward, pulled by means of a capillary movement.
Question 27. How Can I Tell The System Is Working?

Answer :

There are several methods to verify that your device is working, which includes:

Feel for moisture just below the surface of the soil directly above a dripper.
Run micro tubing to the floor on the stop of a area and use it as a factor supply dripper.
Install a flag indicator on the cease of sector.
Monitor flow at the water meter.
Because water travels each upward and outward from the dripper, the soil will typically be damp at, or near, the floor.
