As farmers deplete the soils nutrients, nitrogen and other minerals need to
be added back in. This can be done for short-term gain, by using chemicals,
or long term gain by doing soil remediation with compost and brown/green
manures. With no soil remediation, more chemicals are needed, sending soil
quality downward and costs upward.
