Soil is one of the basic natural resources that supports life on Earth. It is an ecosystem, which is a home to several living organisms, which make the soil alive and give it a good structure and texture.

A living soil ecosystem nurtures and nourishes plants by providing a healthy medium to take roots through a steady supply of nutrients. Use of chemical fertilisers disturbs the natural soil ecosystem and its indiscriminate use has resulted in the degradation of soil. A total neglect of ecological/organic fertilisation by policy makers, extension officers and farmers during the peak Green Revolution period has also added to the soil health crisis.

This report pools together scientific literature as well as farmers’ views on this issues as many a times, while studying issues related to soil health or while making policies related to it, the farmer, who is the most important stakeholder, is seldom consulted. The report has made an effort to rectify this grave inadequacy by including the farmer's perspectives in the academic processes like the social surveys, public hearings and workshops and in this final report. Every section of the report has a component from the existing scientific literature available and another one on the farmers’ opinion on the same area.

 Stating that modern agriculture increases production cost, the author observes that productivity of the same crop was higher in pre-British times than what it is now with modern agriculture techniques.

As these old agricultural techniques have not been scientifically researched there is a lot of scepticism which also results in them not being promoted. The paper lists out agricultural techniques, which result in sustainable high yields and are accepted by the scientific community.

The following article is based on a field experiment in International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), where low cost farming systems that involve use of biological inputs obtained from the field is compared with conventional farming.

Further, the authors offer suggestions for future demonstration and verification experiments, to study the virtues of organic  farming.

This paper was presented at the first National Symposium on System of Rice Intensification (SRI) – Present Status and Future Prospects held in 2006.  The parameters include thirteen soil properties which included six related to cultureable microorganisms, three root-related parameters and yield.

Two of the four systems are low-cost farming methods which are based on traditional and scientific knowledge on using crop residues, farm-waste, compost, Gliricidia lopping, bacterial inoculants, and herbal extracts as nutrients to nourish the soil, and as biopesticides to manage pests.

The third system is conventional agriculture which is the "control" and receives chemical input as suggested by research institutions depending on crop type. The fourth is a combination of the  first three.

Here the yields of crops grown by low-cost inputs including plant biomass are compared with chemical fertiliser-induced production.

The study was conducted over 1999-2004, and the findings conclude that the yields of low intensive biological farming are as good, if not better than chemical fertiliser intensive farming.

Green Revolution (GR) technologies, supported by official policies, and fuelled by agro-chemicals, machinery and irrigation, are well known to have improved agricultural production and productivity. While these technologies greatly helped developing countries to address their food-security and food-sovereignty needs, farmers using these technologies have had to depend on external inputs.
