Meanwhile, individual farmers can do many
things to reduce the flow of nitrogen from
- Increasingly, farmers are
using soil tests and more precise
application to reduce the amount of excess
nutrients that end up in soil, and
eventually in water.
- Some farmers put their
steepest ground to pasture, rotating
livestock through paddocks based on how
quickly the grass recovers. Rotational
grazing helps farmers profit from perennial
grass, which holds soil and water better
than crops do.
- Many farmers mix other
crops, such as oats or rye, into the
rotation with corn and soybeans to help
hold soil and reduce the need to fertilize.
Livestock must be an integral part of the
operation, to make use of these crops.
