Significance of liquid organic manures in sustainable crop production: A review
Manoj KN, Uma V, Kiran SC
The organic manures provide a way for reducing the indiscriminate use of chemical fertilizers and help to maintain the soil health with a positive impact on organic matter recycling. The liquid organic manures helps to achieve higher growth and development of the crops through improved physiological and biochemical processes of the plant, as their application results in rapid availability of macronutrients, micronutrients, growth regulators and other beneficial substances to the plants in addition to enhanced tolerance to biotic and abiotic stresses. They also increase the beneficial microflora of the soil and their activity to a large extent upon soil application and thereby increase the availability of soil nutrients. These liquid organic manures are low cost production technologies as they can be easily prepared from naturally and locally available materials by the farmers, thereby they also offers ecofriendly nature. Thus use of liquid organic manures in agriculture play prime role to sustain the soil fertility and crop productivity.
