Chemical free natural food is not only the need of the hour but also a necessity to keep us and our future generations healthy. What does chemical free mean? When we say that a crop is chemical-free, it means that it is free from chemical fertilizers and its residues.

What is organic farming?

An Agricultural Irrigation System in farming that uses Fertilizers and Pesticides of Organic origin is known as Natural or ORGANIC FARMING. Organic Farming does not make use of synthetic, chemical fertilizers and pesticides, transgenic species, antibiotics, growth-enhancing steroids, etc. But, it uses farming techniques like crop rotation and companion planting, which have changed agricultural practices since the 20th century. These irrigation practices require a good quality Irrigation System Manufacturers & Suppliers in India like Kothari Drip Irrigation Systems and Automation Systems.

What are Natural fertilizers?

Natural Fertilizers are dead and decayed remains of plants and animals, bone meals as well as compost manure and green manure. Natural fertilizers consist of organic matter that contains high organic carbon. High amount of organic carbon increases the growth of micro-organisms and this, results in more oxygen being consumed that is the main issue in organic farming.

Soil fertility

To achieve maximum yield, the quality and fertility of the soil must be high. Soil which contains more than 1.2% of Organic Carbon is good soil and has high soil fertility.

How to maintain the soil fertility?

Soil fertility can be improved by organic farming as it increases the organic matter in the soil which improves the soil texture by adding green manure, bone meals, etc.

Which is the best manure for maintaining the soil fertility?

Partially decomposed organic material is the best manure. Cattle dung is a great source of organic manure. Its fertilizer strength reduces by keeping the dung all year round, so it must be used within 3-4 months.

The soil which contains high organic carbon, organic minerals and matter is known as fertile soil. Fertile soil has high micro-organism activity. These nutrients are food to the microorganisms, so they consume the nutrients which are in a bounded to each other in the soil. This Microbial activity in the soil helps in making nutrients available to the crop root systems. Soil contains all types of nutrients like Nitrogen, Phosphate, Potash, Calcium, Magnesium, Sulphur, Iron, Zinc, Manganese, Boron, Copper, Molybdenum, Chlorine and other trace minerals. The percentage of the nutrients may vary according to the soil type. Organic carbon is the primary food and energy source for these microorganisms. When the amount of organic carbon in the soil increases, so does the microbial activity. This helps increase the availability of nutrients, which results in higher quality and more quantity of yield.

Organic fertilizers are the main and easy source for maintaining soil fertility. Recycling of harvested parts is low cost organic farming. In nature, micro-organisms work as decomposers and carry out the task of recycling. These useful micro-organisms have to be incubated for producing fast and quality half-compost.

Use of pesticides in food crops is one of the main causes of the spread of deadly diseases like Cancer and Neurological disorder. Now is the time to think and adapt to growing Natural Food though Organic Farming!
