Complex biopreparation for maintaining natural fertility in agrophytocenoses

Abstract

The effectiveness of using a new biopreparation for the decomposition of wheat straw, which consists of cellulolytic bacteria CA3 and CU6 and strains-antagonist of the phytopathogenic fungi Pseudomonas laurentiana ANT 17 and Paenibacillus peoriae ANT 13, has been studied. AND 17 and ANT 13 additionally have growth-stimulating activity and the ability to mobilize inorganic phosphates. The greatest degree of decomposition of straw was observed when combined the biopreparation and ammonium nitrate (50.8% versus 25.2% in the control). At the end of the field experiment carrots were grown in soil with decomposed straw. When biopreparation and ammonium nitrate were used for straw processing, the weight of the carrot root crop was 14.4% more than in the control, and the diameter of the root was 55.6% bigger.
