Precipitation: Rainfall
It is important that crops have periods of rain, and periods of dry weather during their growth cycle. During different stages of growth, plants need water for energy for photosynthesis. Dry period are also necessary so crops can be harvested and certain varieties of crops also need time to dry about before they can be processed. Livestock depend on precipitation to help fill ponds and lakes, in addition to providing water for pasture conditions.
Surplus: Too much rainfall can be devastating to a crop. If excessive amounts of rainfall during critical harvesting windows, equipment and personnel can not get into the fields. The standing water increases the chances for rot, and the water can suffocate the oxygen supply in the soil for the root system.Extended rainy periods also increase the potential for a crop to be destroyed by fungal diseases.
Deficit: Too little rainfall can also proved detrimental to crops. Inadequate rainfall can lead to limited soil moisture for plant growth. It can also impact the surface water that is available for consumption of livestock.
