One of the greatest teachers of this method of farming is Masanobu Fukuoka, author of The One-Straw Revolution. In this book Fukuoka describes his discovery of "do nothing" farming, where he creates situations where nature will do the work with the minimum of interference on his part.
So instead of spending hours ploughing the soil or spending money on adding chemical fertilisers to his crops, he simply chucks the rice straw back on the ground after harvesting it and scatters chook poo over it. Occasionally he sows clover to use as a green manure.
And that's pretty much it.
And rather than seeing everything turn into a wilderness and watching helplessly as the prickles take over, Fukuoka actually equals the yield of farms that have had these modern high intervention inputs applied to them, with a fraction of the investment of labour and resources.
