Soil sampling using Trimble GPS now that we have the soil data, we can process the soil maps and the variable rate lime and fertilizer prescription maps. For this job we use FarMWOrKS Software. This software is a leading farm Testing soil pH in our laboratory management software used by farmers all over the world. It helps farmers manage all their records, including field operations, staff, machinery, fertilizers and chemical applications. It has strong mapping module, wher farmers can view soil maps, Google maps, yield maps and field boundaries. after processing the lime and fertilizer applications maps, we upload them into our TrIMBLE Farmworks Software – for precision management of farming operations CFX 750 Tractor display. The CFX 750 is an intelligent GPS system which controls the guidance of the tractor and the application rate of lime and fertilizer, accord to the soil maps. To apply the lime we use a FMD Baldon lime spreader. We have fitted this lime spreader with a variable rate drive, meaning that the rate of lime and fertilizer will change accord to the tractors GPS location and the soil map we have created. Why apply lime and fertilizer when it’s not needed?! We are working with farmers across Kenya to correct their soil fertility for increasing crop yieldsbut we appreciate that these inputs are expensive and difficult to apply, which is why we Soil maps generated using FARMWORKS Software now offer you a complete SOIL MaPPInG anD LIME & FErTILIZEr SPrEaDInG SErVICE .
