What is the drop water in agriculture?

Question

hello

i would like to know about drop water (drop by drop water) in agriculture. at this way, water is spent less. would you pleased if guide me.

thanks

Answer 1

Ag is the biggest water consumer in the world. With the population growing Ag will face more competition from industrial and domestic water users. This is why Ag will have to use water more efficient (drop by drop water) methods that mean to give water to plant in drops (rain like) or drop water methods if you will.

Answer 2

The terms "drip", "drop by drop", and "trickle" irrigation, have been supplanted by the term "micro irrigation", recently adopted by the American Society of Agricultural Engineers. Micro irrigation includes all methods of frequent water application, in small flow rates, on or below the soil surface. Ideally, the volume of water is applied directly to the root zone in quantities that approach the consumptive use of the plants. Through good management of the micro irrigation systems the root zone moisture content can be maintained near field capacity throughout the season providing a level of water and air balance close to optimum for plant growth. In addition, nutrient levels which are applied with water through the system can be controlled precisely. During the dry season in humid areas, or in arid climates, micro irrigation can have a significant effect on quality and quantity of yield, pest control and harvest timing.

Answer 3

I believe you are asking about dip irrigation.

You can use as little as 1/4 the water you use for flood irrigation to get the same or better yields as the ground is not waterlogged so long with dip.

You can use much poorer quality water with drip irrigation than you can with flood or other methods using more water as there are less salts to leave behind in the soil.

Of course it costs more money or labor or both with drip irrigation. As labor and capital are some what interchangeable in irrigation. You can increase the labor or buy more equipment depending on your circumstances. In the end it means the same.

You can water more land with less water of poorer quality by sending more money to do it.

  My wife & I made the choice to put in underground drip on the Texas High Plains 5 years ago at a cost of over a $1000 USD an US acre for an almost automatic system. It won't do much if any better than a row of tin cans with holes punched in them that someone fills with water twice a day. But we can't get the labor to fill the cans.

Answer 4

Drop-by-drop watering is a technique of supplying to a plant only the water it absolutely needs, and minimizing waste by not supplying water to barren ground or weeds.  It can be quite effective in gardens in areas where water conservation is  a critical need, but is too cost/labor intensive for even small farms.

If you are set up for drop-by-drop watering it is relatively easy to add precise amounts of nutrient chemicals to the water so that plants receive full nourishment, but the soil is not polluted.

Answer 5

Agriculture is the biggest water consumer. It uses around 70 percent of all freshwater withdrawals worldwide. With a growing world population, agriculture will face more competition from industrial and domestic water users. This is why agriculture will have to use water more efficiently , from this methods is (drop by drop water) method that means to give water to plant in drops (rain like)
