What are some ways to minimize the need for irrigation?
Trickle or drip irrigation can reduce the amount of water needed for irrigation. So will planting earlier or later in the growing season. You can also water less frequently wi…th a little more volume initially. Over time the plants get enough water deeper, eventually reducing the amount of water required. Some conservation practices address soil as well as water conservation. A whole farm or watershed approach does this by using shelterbelts, riparian buffers, cover crops, applying maximum grazing densities, nutrient management etc. The approach is referred to as conservation agriculture.
Irrigation allowed for job specializationin Mesopotamia which therefore created trade. Trade allowed Mesopotamias' political structure to grow. Irrigation paved the way for tr…ade and economy.

Surface irrigation 2. Localized irrigation 2.1 Drip or trickle irrigation 3. Sprinkler irrigation 3.1 Center pivot irrigation 3.2 Lateral move (side roll, wheel line) irrigation 4. Sub-irrigation 5. Manual irrigation using buckets or watering cans While cultivation the water is transferred to all plants or soil and the technique used is called irrigation. The types of irrigation are:- 1. SURFACE IRRIGATION In this water is spread over whole land or surface. 2. Free Flooding This flooding system of irrigation is used from ancient times. Flooding method consists in applying the water by flooding the land of rather smooth and flat topography. In current irrigation practice, several flooding methods have been developed. In free flooding method, water is applied to the land from field ditches without any check or guidance to the flow. The land is divided into plots or kiaries of suitable size depending on porosity of soil. Water is spread over the field from watercourse. The irrigation operation begins at the higher area and proceeds towards the lower levels. The flow is stopped when the lower end of the field has received the desired depth of water. The field watercourse is properly spaced, the spacing depends on the topography, oil texture, depth of soil and size of stream. 3. Border Strip Method 4. Well and Tube Well Irrigation Well and tube well's water used for irrigation 5. Canal Irrigation Canals are most important source of irrigation from the period of 1960s, but in the 1970s, they yielded first place to wells and tube wells and now constitute the second most important source of irrigation in India. Canals are most effective techniques of irrigation in areas of low level relief, deep fertile soils, perennial source of water and extensive command area. Therefore, the main concentration of canal irrigation is in the northern plain of India, especially the areas comprising Uttar Pradesh Haryana and Punjab. 6. Tank Irrigation A tank act as an irrigation storage system which is developed by constructing a small bund of earth or stones built across a stream. The water impounded by the bund is used for irrigation and for other purposes. Some tanks are built partly as dugouts and partly by enclosing bunds. Tanks are of varying size but most of the tanks are of small size and are built by individual farmers or groups of farmers. Tank irrigation is more suitable in the peninsular plateau area such as Andhra Pradesh (Including Telangana) and Tamil Nadu. 7. Drip irrigation In this tubes are set up in grounds through which water is transferred. It is also called trickle irrigation. 8. Sprinkler Irrigation In the sprinkler technique of irrigation, water is sprinkled into the air and allowed to fall on the ground surface just like rainfall. The spray is done by the flow of water under pressure through small orifices or nozzles. The pressure is generally obtained by pumping. Through proper selection of nozzle sizes, operating pressure and sprinkler spacing the amount of irrigation water required to refill the crop root zone can be applied almost uniform at the rate to suit the infiltration rate of soil. In agriculture, almost all crops are suitable for sprinkler irrigation system except crops such as paddy and jute.

Farmers need to use irrigation because there's little precipitation in the Interior Plains.
The process of supplying water by artificial means is called irrigation.
Because there was plentiful rainfall
need of irrigation: insufficient of rainfall uneven distribution of rainfall improvement of perennial crops. mode of irrigation: 1. Lift irrigation 2. flow irrigation
Irrigation engineering is related tothe civil engineering. Irrigation engineering is a wide field. There are lot of things to learn. Civil engineer can become a irrigation e…ngineer. that is why you should learn the irrigation engineering.
because if the irrigation is done properly the farmers can work properly on their fields without facing any problem of water it is also necessary because even during famine no… field is left without water and even then our country can progress well and it is useful for our coming generation also
The use of reusable energy sources is the best efficient way to get rid of fossil fuel pollution. Some examples are - wind power, solar power, and hydro power.Also, using a hy…brid car reduces the amount of pollution put into the air and can save you a lot of money in gas every year; with some getting 40 mpg.Keeping a large amount of trees on the earth also is a huge help. Trees "breathe in" carbon dioxide and "exhale" oxygen. A: We can use less of it.We can stop using it.We can replace it with renewable energy (solar, wind, water, hydro, tidal and wave, geothermal, ocean thermal, biomass and biofuel).
water reserves are the ultimate source of life on earth. Proper water management must be practiced in order to save water. The ground water table is decreasing day by day. Thu…s, it is important for the farmers to adopt scientific method of irrigation; so that they can gain maximum production out of minimum uses of resources. In countries like India, the cultivation of crops by the help of ground water (irrgatin potential) has increased by 10% in the last 30 years.
Minimal can be different depending on the person. if a rich man thought of the minimal price on something to sell he might think millons of dollars. it depends on how yo…u see anything in any quantity. Thanks for asking qwerman.
Water reservoirs that are often man-made, pipelines that extend from a lake or river to fields, or a large underground aquifer to source their water from, such as the Ogal…lala Aquifer in the United States.
