Abstract:

Precision Agriculture (PA) is a whole-farm management approach using information technology, satellite positioning (GNSS) data, remote sensing and proximal data gathering. These technologies have the goal of optimizing returns on inputs whilst potentially reducing environmental impacts. This study was conducted out to determine the acidity, salinity, field capacity, permanent wilting point and water holding capacity in precision agriculture by analyzing soil samples taken from the field in 32 points. Maps were drawn by obtaining data from the field. The purpose of this research is to use the geographic information system for comparing the obtained data from soil more quickly and easily than before and also the water amount in order to make precise decisions for agriculture progress and applying the appropriate inputs which is related to water. The present results also indicated that water holding capacity maps. These maps are usage for the irrigation management and the information from different points of the field. These data obtained the field has an important role in the management of precision agriculture.

Abstract:

A tractor simulator was made for hard tillage work. The aim of the simulator was to have it in national language and that it is easy to use. There are tractor simulators available but they are mainly made for different conditions than we have and they are also in languages not common to our farmers. The simulator user can interactively experiment how working depth and – width, soil conditions, ballasting and driving speed effect on wheel slip, field capacity and fuel consumption l ha-1. The simulator also shows how complicated a tractor – implement system is. Because the soil conditions and implement conditions are varying there can be large scatter in the results.
