In Argen'na more than 22 millions Ha are no-till cul'vated land. There is an increasing warning and consciousness about looking for sustainable uses and managements of soil. We have previously shown that the typical 3 years crop rota'on in Argen'na: Wheat/Soybean-Corn-Soybean was enough to sustain bacterial diversity at the regional level, while monocropping reduces it1. Moreover we show that many soil biological characteris'cs can discriminate between monocropping or a typical crop rota'on history2,3,4. A group of farmers from AAPRESID (Argen'nean Associa'on of No-Till Farmers) go further with this model, and try the effects on soil produc'vity and quality, of intensifying and diversifying crop rota'on.
