THE IMPORTANCE OF THE SERRA GERAL AQUIFER SISTEM TO THE SOYBEAN CULTURE
The lack or insufficient amount of rain fall during the blooming and growing periods of soybeans are one of the major factors that cause either complete loss or large reductions of harvest areas in the southern region of Brazil. Within the Paraná State the soybeans agriculture covers an area of appr...
