The soil resource is a very important aspect of planning an AWMS as it is most often the medium used in the final assimilation of many of the agricultural waste products. The application of organic agricultural wastes has a beneficial influence on the soil condition by improving tilth, decreasing crusting, increasing organic matter, and increasing infiltration.
Waste must be applied to the soil so that the constituents in the waste do not exceed the soil's capacity to adsorb and store them. The rate at which wastes are applied must not exceed the soil's infiltration rate. Application of wastes at a rate that exceeds the soil's infiltration rate can result in runoff, which can cause erosion. Plant nutrients in solution or those attached to the soil particles along with bacteria, organic matter, and other agricultural material may be transported to the receiving water.
