Among the several causes, critical low soil organic
matter status is predominant for decline in soil health
and consequent fall in crop productivity. Over the
years, availability of traditional source of soil organic
amendment, viz. cattle manure drastically declined
due to various reasons (domestic uses as fuel and plas tering of the kachha houses). The present study high lights that there are many alternative sources of soil
organic amendments available in the country which
have tremendous potential to improve soil organic
matter status and crop productivity, and rejuvenate
and enhance the dying total factor productivity of
Indian soils. Data from various sources reveal that
about 300 million tonnes of alternative sources of soil
organic amendments are available in the country. This
study highlights that the application of alternative
sources of organic amendments directly or indirectly
improves soil health by influencing many soil proper ties (physical and chemical) and enzyme activities
(biological) that regulate nutrient dynamics in the soil.
Consequent upon improvement in soil environment,
the application of alternative sources of soil organic
amendments alone or along with recommended dose
of fertilizers registered significantly higher yield in
different crops across different agro-climatic condi tions of the country. Composting and vermicompost ing are the best strategies to convert the biomass of
available alternative sources of organic amendments
to plant nutrient-rich products.
