Management options to increase return on fertilizer dollars
1. Adopt management practices that increase forage use in pastures such as
management intensive grazing.
-
Note that management intensive grazing increases
the nitrogen value of manure
returned to the pasture by grazing
animals. "Specialists estimate you
can decrease recommended nitrogen
rates 20% for the same yield goal on
management intensive pastures."
2. Only fertilize when increased forage production is needed.
-
Cool season grasses respond to spring fertilizer but is that extra production
needed? Unless excess spring production
is harvested as hay, carefully consider
spring fertilizer rates.
3. Considesr alternate sources of nitrogen.
-
Legumes remain an excellent
source of nitrogen for pastures. Manure may be
a more economical source of fertilizer
nutrients. Remember that manure nitrogen
is typically 50 to 60% available
when it is surface applied put 100% of
manure phosphorus and potassium is
available to the crop.
