sustainable agriculture the contemporari ‘’ sustainabiliti’’ record
first some general points regarding the sustainability of american
agriculture at the present time second the problem faced by american
agriculture that could undermine sustainability differ greatly by region
both in degree and character third environmental concerns are the most
volatile element in the sustainable equation today in the united states
fourth conventional farming practices in many major farming regions
today are sustained economically at least in part by high levels of
government support fifth sustainable farming systems and practices will
be adopted when and only if they offer farmers a convincing opportunity
to earn higher profits than from other system taking into account all
existing government program options and policies that have impacts on
farm-level economic decision-making sixth new technologies particularly
biotechnology could shift the economic viability of sustainable
production systems dramatically by providing genetic and biological
solutions to long-standing pest control problems by increasing levels of
nitrogen fixation and through novel animal husbandry practices finally
we also must remember that current systems often are used because they
were used the year before are proven reduce short-term risk and require
modest public and private investment in education training management
skills and equipment page 2 of 2 features of sustainable systems crop
rotations in row-crop systems continuous cropping patterns generally
would be replaced by multiyear rotation including field crops legumes
and forage crops nutrient management a much more careful job can and
must be done in estimating nutrient needs weed control rotation and
tillage would be relied upon more heavily to gain an acceptable level of
weed control insect control american agriculture faces a wide array of
insect pest only some of which routinely require insecticide treatment
livestock production trends toward large livestock operations and high
livel of livestock concentration in limited geographic areas would
reverse consequences cost and benefits stewardship of natural resources
new policies adopted in the food security act of 1985 have brought about
tremendous progress in controlling excessive soil erosion improving
water quality by far the most significant benefit in the united state
that will evolve as progress is made toward sustainable agriculture will
flow from improved water quality economic performance despite shrinking
surpluses and rising prices triggered by the severe drought of 1988
american agriculture still faces a serious long-term competitive
challenge in world commodity markets 2 of 2 displaying resume b
