Technological changes and their consequences for plant cropping

Abstract

The survey deals with some problems of industralized agriculture development and its conditions. This development was promoted both by economic and biological progress, whereas advances in plant breeding enabled to completely mechanize technology of various crops cultivations claimed to be difficult enough (e.g. maize and sugar beet). It resulted in enormous energetic inputs for agricultural production (machines, fertilizers, pesticides), environment degradation and in many cases lowering of agricultural products quality. Some items associated with energetic inputs for agricultural production in Poland are presented
