| Soil nitrogen content has often showed highly variability due to intrinsic soil spatial heterogeneity and the methodology applied to measure it. Labs procedures of this methodology are time consuming being one of the main reason to sampling a reduce number of points beside its cost. The objectives of this study were to analyze nitrogen variability in a soil transect through the variability of a wheat crop. In order to do that plant weight, grain weight and N uptake were measured every 0.5 m along a line obtaining 157 samples inside the crop field. Earlier than the beginning of the wheat crop, the plots were used for melon crop experiments to optimize fertirrigation. The agronomic practices created a higher variability in soil Nitrogen content and a record of the spatial location of the plots, fertirrigation lines and the treatments applied were kept. No fertilizer or organic amendments were use for the cereal crop. | |
