What is the best amount of rain for agriculture?

    Rain water is preferred for its quality compared to saline water. Rain water should be captured and stored. Crops that consume less amount of water like sorghum have to be planted instead of sugarcane and cane sugar is not needed for a world whose large number of people suffer from diabetes and obesity. Micro-irrigation methods like drip-irrigation and sprinklers have to used to provide right amount of water around the root portion every day. Vertical farming and ponics or soil-less farming should be developed to save on use of land and water and prevent heavy rains and flooding or high temperatures from damaging the crops.

    Depends on your crop(s).  My pop always said an inch of rain a week for corn & soybeans.

    it depends on what you are trying to grow, or if you are doing livestock agriculture. Some crops require minimal precipitation. What tends to matter the most is your soil, because some soils have better water retention than others

    That question cannot be specifically answered. That is because plants throughout the world have adapted to particular climate regimes. Crops such as grains grow best under temeperate conditions with cold winters, mild summers, and an average rainfall of between about 20 to 30 inches annually. Citrus trees cannot tolerate the cold and grow in much warmer climates with about double the rainfall.

  • Enough but not too much to get best yields and quality.

    That depends on what you are raising. Bananas, for example, require a lot more than switchgrass (for ethanol production).
