Irrigation water only needs to be clean enough to not clog up whatever method is used to apply it to the crops. It does need to be free of anything toxic to the plants, livestock, or humans. River and lake water are commonly used irrigation water sources, along with underground water pumped to the surface.
What else can I help you with?
Why must farmers in region rely on irrigation?
There's not enough rain to water the crops. The farmers have to get the water that runs off the mountains to where the crops are.
Why must farmers in the region rely on irrigation?
Farmers in the region often rely on irrigation because the natural water supply through rainfall may be insufficient or unreliable to support crop growth. By using irrigation, farmers can ensure a consistent water supply for their crops, leading to higher yields and better overall productivity.
How could farmers water crops when it was hot?
If they had access to irrigation and had irrigation equipment set up, then they would use that to prevent crops from getting to dried up. Others who have or had no access to irrigation would simply have to hope the rains come soon and that the drought won't last for too long. These latter farmers rely on the rain to water their fields, primarily because the location has been known to have a high annual precipitation or high annual rain fall.
How do farmers in the California Valley get water during the dry seasons?
Farmers in the California Valley get water during dry seasons primarily through irrigation systems that rely on reservoirs, wells, canals, and pipelines for water delivery. In particular, they may also use technology like drip irrigation to efficiently water crops and maximize water usage. Some farmers also participate in water-sharing agreements or utilize groundwater pumping to supplement their water supply during dry spells.
What system allowed farmers to no longer rely exclusively on rain to water their crops?
Artificial irrigation. By dykes and wells. This has evolved greatly today to include huge hoses and sprinkler systems
Why are summer monsoons so important to farmers in the Deccan plateau?
Because there is so little rainfall throughout the year in the Deccan Plateau, farmers rely on summer monsoons for the water they need. Each year, these storms bring water that can be used for irrigation and crops. This allows farmers to grow food in areas that are often dry for many months.
What would be happened if drip system of irrigation was not used?
Without the use of a drip irrigation system, crops would rely on traditional irrigation methods, which can lead to inefficient water use and increased evaporation. This might result in water scarcity, particularly in arid regions, and can lead to overwatering or underwatering plants. Consequently, crop yields could decrease, soil erosion might increase, and farmers could face higher costs due to the need for more labor and resources to manage irrigation. Overall, the absence of drip irrigation could threaten food security and sustainability in agriculture.
Why were monsoons important to farmers?
Monsoons are important to farmers because they bring much-needed water for irrigation, replenish soil moisture, and support crop growth. The timing and duration of monsoons are critical for planting and harvesting agricultural crops, making them a vital source of water for agriculture in regions that rely on seasonal rainfall.
What river did Cahokia farmers rely on for water but feared flooding?
Mississippi
Is the ganges used to water crops?
Yes, the Ganges River is extensively used for irrigation in agriculture. Its waters are diverted through canals and other irrigation systems to water crops in the fertile plains of northern India. This practice supports the livelihoods of millions of farmers who rely on the river for their agricultural activities. However, pollution and over-extraction of water are significant challenges facing this vital resource.
What is monsoon and how do monsoons help farmers?
Monsoon refers to a seasonal wind pattern that brings heavy rainfall to certain regions. Monsoons are crucial for agriculture as they provide water for crops, replenish soil moisture, and support farming activities. Farmers rely on monsoons for irrigation, which is essential for crop growth and food production.
What would be the effect of the Ogallala Aquifer going dry?
If the Ogallala Aquifer were to go dry, it would have severe consequences for agriculture in the Great Plains region of the United States. Farmers rely heavily on the aquifer for irrigation, so a depletion would lead to decreased crop production and economic hardship. It would also impact drinking water supplies and ecosystem health in the region.
