Intensywność nakładów chemicznej ochrony roślin w gospodarstwach prywatnych a obciążenie środowiska w południowo-zachodniej Polsce

During the years 1992-1997, the intensity of inputs directed on chemical plant protection in the private farms in 14 gminas, located in the south western region of Poland was examined. The research was based on the data collected from a representative sample of 679 private farms. The research findings show that the most intensively protected plants were rapeseed and fodder root crops and that the highest profitability of chemical plant protection was in the case of cereals and potatoes. Comparing selected regions, it is worth to state that the basic plants were the most intensively protected in the zones of sanitary protection and in the plain regions of high soil quality. The low input intensity was noted both in plain regions of low soil quality and in the mountain regions.
