While organic agriculture practices result in higher soil organic matter (SOM) contents and, in turn, higher nutrient - and water - supplying potential to crops, transition to organic farming typically involves a lag time of several years in which yields can suffer and input demands increase as rebuilding soil microbial communities compete with crops for nitrogen and other available nutrients (Simmons and Coleman, 2008).
