ABSTRACT

In agroecosystems, the farmer is, in a sense, the organism with the greatest impact on the environment in which crops are grown. The farmer alters and adjusts conditions of the physical as well as the biological environment to meet the needs of the crop or crops. To do so sustainably, the farmer must have an understanding of the biotic interactions of the agroecosystem — how each member of the community impacts the agricultural environment and alters conditions for its neighbors.
