Application of multivariate analysis techniques to an experiment in which sewage sludge is applied to a strawberry field

摘要

Intensive farm work on very permeable sandy soil, causes solutions that are highly nitrogenated, due to excessive fertilizatiom to descend quickly into the saturated zone, with the result that water and fertilizer are wasted and, in the end, the subterranean waters become polluted. The main objective of this study is the use of multivariate analysis techniques to study the impact of this sewage sludge treatment on the flow of contaminants through the unsaturated zone.
