Theoretical bases for enhancing perennial crop farming.
2017
Based on analysis of the sixty-year long field, vegetation, miniature, lysimetric and laboratory research, completely new theories for recovery, improvement and regulation of the degraded soil under perennial crops are developed. The optimal planting depth of soil is defined by: the humus layer thickness, its fertility, the properties of lower layers of soil and the characteristics of the root system arrangement of the perennial crops; given the perennial crops’ cultivation specifics under conditions of present-day machinery and technologies, the conduct of land treatment ascribes the major role among soil-forming factors to the man-made one. The article lists the recommendations to be introduced in production that are to be estimated based on crop capacity, quality characteristics of the obtained product and changes in the soil characteristics.
