Mulching (484): Applying plant residues or other suitable materials not pro-
duced on the site to the soil surface.
Nutrient Management (590): Managing the amount, form, placement, and tim-
ing of applications of plant nutrients.
Pasture and Hay Planting (512): Establishing and reestablishing long-term
stands of adapted species of perennial, biennial, or reseeding forage plants. (In-
cludes pasture and
renovations. Does not include grassed waterways
outlets on cropland.)
The long-term effect will be an increase in the quality of the
water
to
reduced erosion and sediment
Increased
and subsequent
percolation may cause more soluble substances to be carried to ground

With the reduced runoff there will be less erosion, less sediment and substances
transported to the surface waters. The increased infiltration increases the possi-
bility of soluble substances leaching into the ground
Pipeline (516): Pipeline installed for conveyin, water for livestock or for recre-
ation
Pipelines may decrease
organic, and bacteria pollution from
livestock. Pipelines may afford the

sources
other than streams and lakes, possibly keeping the animals
from the stream
or impoundment. This will prevent bank destruction
resulting sedimentation,
and will reduce animal waste deposition directly the water: The reduction of
concentrated livestock areas will

Planned Grazing System (556): A practice in which two or more grazing units
are alternately rested and grazed in a planned sequence for a period of years, and
rest periods may be throughout the year or during the growing season of key
plants.
Planned grazing systems normally reduce the system time livestock spend in each
pasture. This increases quality and quantity of vegetation. As
quality
increases,
content in manure decreases which speeds manure decomposition
and reduces pollution potential. Freeze-thaw, shrink-swell, and other natural soil
mechanisms can reduce compacted layers during the absence of grazing animals.
This increases infiltration, increases vegetative growth, slows runoff, and im-
proves the nutrient and moisture
and trapping ability of the area.
Decreased
will reduce the rate of erosion and movement of sediment and
dissolved
sediment-attached substances to
courses. NO
increase in
water pollution
be anticipated from the
of
this practice.
Pond (378): A water impoundment made by constructing a dam or an embank-
ment or by excavation of a pit or dugout.
