Variability in permanent pastures: contribution for a precision agriculture project

Abstract

In this work are published the results of a systematic evaluation of a permanent pasture in terms of physical and chemical soil properties and floristic composition. This geo- referenced information constitutes the decision support in a Precision Agriculture project that uses differential application of fertilizers.

Data are presented regarding analyses made before the first differential application and after it. The obtained results show the importance of spreading fertilizers in a differential way, namely the spreading of Phosphorous. In terms of the pasture development it was also evident the effect of a very dry agricultural year.
