According to the United States Geological Survey (USGS), water used for irrigation accounts for nearly 65 percent of the world’s freshwater withdrawals excluding thermoelectric power (1). Biology Part 1: The Cell. Duburque, IA, USA: Wm. For example, if a chronic test in fish showed no effects at 10μg/L, an assessment factor of 10 is still added, meaning that the acceptable concentration in water would be only 1μg/L. In agriculture, water must be of suitable quality to irrigate crops or provide drinking water for livestock. Old But Still Fun: Do fishes drink water?

[FAO] Food and Agriculture Organization of the United Nations. (1978) explained that under conditions that favor high absorption and low transpiration rates, there is build-up of high turgor pressure in the region of cell elongation which causes maximum swelling of the cells. In addition, it serves as a growth medium in hydroponics, the culture of plants in soilless nutrient solutions. Irrigating crops with contaminated water can then lead to contaminated food products which lead to illness when eaten. 5. (1978) explained that under conditions that favor high absorption and low transpiration rates, there is build-up of high turgor pressure in the region of cell elongation which causes maximum swelling of the cells.

This is clear based on the statistics from the United Nations, notably UN-Water and the Food and Agriculture Organization (FAO). The importance of water relates to its essential functions in It also gives producers greater control over plant and animal production, processing, distribution, and storage, which results in: Irrigated agriculture is dependent on an adequate water supply ofusable quality. Some examples include improved irrigation scheduling and crop specific irrigation management.
