   Note: Effects are qualified with a plus (+) or minus (-). These symbols indicate only an increase (+) or a decrease (-) in the effect upon the resource, not whether the effect is beneficial or adverse.


The diagram above identifies the effects expected to occur when this practice is applied according to NRCS practice standards and specifications. These
effects are subjective and somewhat dependent on variables such as climate, terrain, soil, etc. All appropriate local, State, Tribal, and Federal permits
and approvals are the responsibility of the landowners and are presumed to have been obtained. All income changes are partially dependent upon market
fluctuations which are independent of the conservation practices. Users are cautioned that these effects are estimates that may or may not apply to a
specific site.
