Conteúdo: | Electronics and computers are rapidly advancing into agricultural systems management. Silicon and software now impact strongly production agriculture as well as industry in general. In the next few decades electronics and computer applications in agriculture will be as significant as were materials and fluids technologies in industrialized economies over the last ten years. A mesure of this shift is that the electronics content of agricultural machinery and products used in agriculture will represent a multibillion-dollar market worldwide by the year 2000. For agriculture of the most significant opportunities and solutions lie within the domain of instrumentation applications. The scope and importance of technical developments in the last years amply demonstrate this benefit. This paper present the suitability of PIXE to study the trace metal Zinc in soil, showing additionally that many solutions in agriculture lie within the domain of instrumentation development. So far, processes involed in Zn adsorption, as well as for many other elements, are not completely understood. soil samples were analyzed using both PIXE and the classical procedure of INAA technique for comparison. Results showed that there is a good linear relationship for Zn concentration obtained using these techniques.
