A software of soil- compaction map with application in precision- fanning

Fast computers and powerful) data management &graphic softwares are indispensable elements of precision farming technology. Activities like yield monitoring and on the go soil sampling provide vast amount of data on the variation in crop and soil conditions. throughout the field. The collected data must be processed and reduced into maps to provide serviceable information. The objectives of this study were to develop a software for analyzing the compaction data of a soil excavator and convert it into a colored map. A program was written in C++ language with about 2000 lines and it was evaluated by a simulation method. For testing the software, a force measuring hydro-electronic transducer was designed and fabricated. By exciting the transducer its output signals were sent to the software which was loaded on a Pentium PC. Execution of each part of the program follows a flow chart which starts by an icon identifier on the main display. On line progress of the compaction map was visible during the operation period of the transducer. After conduction of each test and making the selevant file, tables of data and functional plot of compaction versus depth at any soil profile is accessible. Results showed that with high confidence, this software could be conjugated on soil compaction scanning. Its facilities seem to be valuable enough to make it as a geographical information system (GIS) software.
