How rain is useful for farmers?

A good balance of rain and proper irrigation can lead to faster-growing plants, which can cut down on germination time and the length between seeding and harvest. The crops are dependent on water during their entire lifecycle in order to survive and thrive.

How can we prevent agricultural water pollution?

Applying fertilizers in the proper amount, at the right time of year and with the right method can significantly reduce how much fertilizer reaches water bodies. Keeping animals and their waste out of streams keeps nitrogen and phosphorus out of the water and protects stream banks.
