The third hypothesis proved partially incorrect. The
management schemes used on the rye cover crop had no effect, on the
average, on the ear leaf area, weight, or N concentration. The
same was true for clover except that the management schemes did
have an effect on ear leaf N concentration. The conventional-
tillage green manure and the no-tillage mulch schemes had a higher
average N concentration then the other schemes.

 There are many different scenarios that farmers find
themselves in. One may have livestock to feed, another may want to
sell off the forage, while a third may not have access to or funds
to attain N fertilizer to supplement his corn crop. However, based
on resource conservation as well as producing healthy, N sufficient
corn, under the crimson clover cover crop at the lowest cost
overall, no-tillage mulch would be the BMP.

 Rye as a cover crop, is very effective in recovering soil
nitrate.2 Rye provides for very low nitrate leaching which means
far less risk of ground water pollution. Based on land
conservation as well as producing healthy, N sufficient corn, under
the rye cover crop at the lowest cost overall, the best management
scheme would be no-tillage mulch.

 Our world is becoming more environmentally conscious everyday.
We are beginning to see into the future and what will happen unless
we take care of our earth. No longer do we use goods and throw
away the containers, we recycle. Thus, we should do the same with
our soil from which our food grows. No-tillage is the best
management scheme for the long-term farmer. Its benefits far
outweigh its disadvantages. No-tillage reduces nitrate leaching
under corn systems which reduces the risk of ground water
pollution.13 Thus, while conserving some resources such as fuel and
soil, no-tillage farming protects others.
