The organic and natural farming methods used in parts of Asia - especially India, utilizes livestock for much more than just manure. You should look up Zero Budget Natural Farming (ZBNF) by Subhash Palekar. Quoting from this site: https://www.civilsdaily.com/news/zero-budget-natural-farming-zbnf/ https://www.civilsdaily.com/news/zero-budget-natural-farming... The “four wheels” of ZBNF are ‘Jiwamrita’, ‘Bijamrita’, ‘Mulching’ and ‘Waaphasa’. - Jiwamrita is a fermented mixture of cow dung and urine (of desi (Indian) breeds), jaggery, pulses flour, water and soil from the farm bund. - This isn’t a fertiliser, but just a source of some 500 crore micro-organisms that can convert all the necessary “non-available” nutrients into “available” form. - Bijamrita is a mix of desi cow dung and urine, water, bund soil and lime that is used as a seed treatment solution prior to sowing. - Mulching, or covering the plants with a layer of dried straw or fallen leaves, is meant to conserve soil moisture and keep the temperature around the roots at 25-32 degrees Celsius, which allows the microorganisms to do their job. - Waaphasa, or providing water to maintain the required moisture-air balance, also achieves the same objective.
