Eps 5: Irrigation Agriculture
The goal is to apply the water to the plants as uniformly as possible, so that each plant has the amount of water it needs, neither too much nor too little.
Surface irrigation, also known as gravity irrigation, is the oldest form of irrigation and has been in use for thousands of years.
The water application efficiency of surface irrigation is typically lower than other forms of irrigation.

Irrigation is a method by which plants are supplied with a controlled amount of water at regular intervals. The Department of Water Consumption and Efficiency operates an integrated network of 145 automated weather stations across California.
In addition, irrigation has several other uses in crop production, including protecting plants from frost, suppressing weeds growth in cereal fields and preventing soil consolidation. It is used to help manage disturbed soils, such as in drought-prone areas, and to protect crops.
Irrigation systems are also used to suppress dust and to dispose of waste water from mining. Irrigation is also an important source of water for irrigation systems in agriculture and for wastewater disposal.
There are many types of irrigation systems in which the entire field is supplied with water evenly. Irrigation is also used in areas where it rains irregularly or dry, or where drought is expected.
In most countries, irrigation typically involves a variety of irrigation systems that use water to maintain crop growth, including arable and crops, and pastures. Irrigation water can come from natural sources such as rainwater, treated wastewater or groundwater. The term "irrigation" is used in the United States and other countries and is used by the United States Department of Agriculture and the National Oceanic and Atmospheric Administration.
In some countries, irrigation may also include self-harvesting and delivery, covering a wide range of crops and pastures such as wheat, barley, maize, soybeans, rice and wheat. In dry areas, crop production is largely dependent on irrigation, but in many countries, agriculture is predominantly dependent on rain and food. About 1% of irrigation water is derived mainly from natural sources, mainly rainwater, groundwater or other fresh water sources. Irrigation is also used in areas with water shortages to supplement periodic deficits and to irrigate in drought conditions.
Water Resource Management in agriculture works in a variety of ways, including irrigation, hydropower, water management, land use, irrigation systems and water conservation.
Irrigation and water withdrawal are generally decreasing in conjunction and follow the same trend. Where there is a large irrigation sector, water consumption determines the overall trend, and trends in agricultural water abstraction follow, implying that irrigation plays an important role in the management of water resources in agriculture in general and irrigation in particular.
If you consider it necessary to irrigate plants with high water requirements in dry regions, drip irrigation should be considered as a solution.
A well-designed drip irrigation system loses virtually no water through runoff, deep infiltration or evaporation. Drip irrigation can be done on polluted plants through plastic tubing, which is placed directly in the root zone of the plant.
Compared to a surface flood system, the amount of water required to grow a crop in a drip system is greatly reduced due to the shorter application times. The irrigation planning can meet the requirements of the harvest and promises a higher yield and higher quality.
Depending on the year and summer, you will need between 1,000 and 2,500 gallons of water per hectare per day, depending on the harvest, like onions grown in Treasure Valley under drip irrigation. For example, furrow irrigation typically uses about 1.5 to 2 million gallons per hectare of irrigation water.
To determine the application rate, use a combination of water temperature, humidity, soil moisture and other factors. Irrigation is done by artificial water application to the soil to support harvesting in dry areas or in times of insufficient rainfall. It also protects plants from frost, prevents soil consolidation, suppresses weeds growing in cereal fields and suppresses the growth of weeds that can damage plants such as weeds, weeds and weeds.
Many farmers rely on rain to irrigate their crops because they grow in dry climates, experience unpredictable rainfall, or want to increase their yields for other reasons. By contrast, agriculture that relies only on direct rainfall is called rain - nutritious agriculture.
Although the reasons for farmers to use one system or another are varied and sometimes complex, any system can affect the yield of a given crop and the quality of the water available. For farmers using irrigation systems, irrigation systems have advantages and disadvantages that distinguish them from each other. However water-efficient a system may be, it may have limitations, which often leads to intensification, which in turn can lead to overexploitation, which negates efficiency gains.
