Bearbetningsfritt jordbruk kan inte tillämpas överallt.
http://www.ag.ohio-state.edu/~news/story.php?id=5063"The message here is that no-till is not applicable everywhere as a means of practicing carbon sequestration. There are situations where other carbon sequestration methods would be more effective," said Rattan Lal, a soil scientist with Ohio State's Ohio Agricultural Research and Development Center. "I'm not saying that no-till is not good. It is a good practice, but it does not work for all soils, for all crops and all conditions. We must not make carbon sequestration synonymous with no-till. The strategy is to develop a system of soil management in which carbon input into the system exceeds the output."
"Basically, those soils that are well-drained, are silt/silt-loam in texture, warm quickly and have some sloping characteristics prone to erosion are excellent candidates for no-till," said Lal, director of OARDC's Carbon Management and Sequestration Center. "Clay soils or other heavy soils that drain poorly, are prone to compaction and are in areas where the ground stays cooler may not always increase carbon storage through no-till."
Som jag läser detta så är en stor del av de svenska jordarna olämpliga för bearbetningsfritt jordbruk. Det stämmer också med egna mycket blygsamma försök på olämplig jord...
