Site-specific crop management has been proposed as a means of managing the spatial variability of soil related, anthropogenic, topographic, biological and meteorological factors that influence crop yield. A 30 ha cotton field located in the Broadview Water District on the West Side of the San Joaquin Valley in central California was used as the study site. Four recommendations are made on improving cotton productivity: (i) reduce the leaching fraction in highly leached areas (i.e. areas where LF >0.5), (ii) reduce salinity by increasing leaching in areas where salinity is >7.17 dS/m, (iii) increase the plant-available water in coarse-texture areas by more frequent irrigation, and (iv) reduce the soil pH where it exceeds 7.9.
