Abstract
In this work, the contribution of nitrogen from three doses of pomace compost in two successive crops was evaluated over three years (2013-2015). The first crop was melon, cultivated under dip-irrigation and the second one was a rainfed cereal (wheat) as a reference. Relative entropy (E(?)) parameter was used to investigate the residual effects of fertigation treatments applied to a previous crop (melon) on wheat and grain biomass. The wheat crop covered nine subplots from a previous experiment on melon responses to fertigation. Each subplot had previously received a different level of applied nitrogen (Napp), and the plants from the previous melon crop had already taken up part of it. Many factors affect these variables, causing them to vary at different scales and creating a non-uniform distribution along a transect. Correlations between the two variables and Napp showed high volatility. A discussion on the utility of using a cover crop as a reference for the use of Nitrogen is exposed.
