Tolerance of wheat crop [Triticum aestivum] towards the spreading heterogeneity of nitrogen manure. The homogeneity of fertilizer application depends mainly on the regularity of transversal distribution. During the last few years, we have tested more than 300 distributors on farms. Results show big differences between the machines (CV between 5/ and more than 50/). The result is linked to distributor features, fertilizer characteristics and user skills. Moreover, crop yield is a function of fertilizer availability for plants. In the case of wheat, nitrogen is particularly important. Using farm application data, a simulation of wheat yield is built in relation with an increase of typical distribution mistakes. Thus, it is possible to assess an acceptable level of heterogeneity for the crop. |
