Biostimulants and its influence on soil properties and crop production

Biostimulants for sustainable crop production

Abstract

Environmental pollution is one of the most pressing global issues and it requires priority attention. There is increasing demands to increase the productivity of crops grown in unfavorable soil conditions. Biostimulants are substances widely used in agriculture to raise crop production and resistance to various types of stress and advantages of agricultural practices andit is more environment eco-friendly products. These are new concept has also accepted their ability to work against the injurious effects of pollutants on plants. Biostimulants consist of many different compounds with positive effects on plants, excluding pesticides and chemical fertilizers and regarding various substances of organic compounds. They are derived from amino acid hydrolysate, plant extracts biostimulants, humic substances, protein ands eaweed extracted are used. The application of biostimulants stimulated microbial activity influences soil biological properties and their microbial communities in field conditions. It also stimulated soil physical properties i.e. soil structure, soil porosity, structural coefficient with increased soil moisture content and decrease bulk density, along with, increase total carbon, nitrogen and the effects of physicochemical properties. These mechanisms of action of biostimulants help to maximize agricultural yields under stress conditions which provoked by climate change. Further, there is need tolong-termstudies to evaluate the effects of biostimulants on crop yield and soil resilience.
