NEW DEVELOPMENTS IN CROP ROTATION

Abstract

Climate change is already affecting agriculture, with effects unevenly distributed across the world. These changes will undoubtedly lead to a reconsideration of the question of the necessary crop rotations on the territory of the individual continents and sub-regions. Many researchers have conducted field experiments with different crop rotations on several soil types and have received determined results, but still lack concrete unified numerical estimates of the influence of different crops in them. This article presents several new developments of the problem in crop rotation. Different approaches to assessing the influences of predecessors are illustrated. Therefore, it is necessary to apply advanced mathematical-statistical methods and models for obtaining more precise estimates. The application of asymmetry analysis and Procrustes analysis in the evaluation of different crop rotations are given in details. Some results about favorable and unfavorable rotation pairs are given.
