Logistic models for distribution of straw in crops of fruit tree plots where mulch is applied

Abstract

[EN] This work presents three models for the linking of fruit tree plots which are receptors of rice straw that is applied as mulch, with other straw suppliers plots, whose straw is a byproduct of cultivating cereal. The mulch is applied to fruit tree plots in order to save irrigation water, to reduce the incidence of weeds and to reduce erosion. In other words, they intend to assign a set of supplier plots to each straw receiving plot. Each model solves the problem in one scenario. The first one considers the direct application of straw to a single plot which must be supplied to apply the mulch from several plots. Therefore, these must be selected from a set that act as suppliers. It is not considered prior storage or collection. The second scenario also involves a direct application but in several receiving target plots from several source supplier plots without storage or intermediate storage. The third scenario develops a model that groups provider plots with different collection points; It offers a system that selects the location of the storage points and associates each storage point with a group of receiving plots.
