We all know that global warming is one of the problem in all of us, we need to do something to avoid or may lessen this problem. And one of the best we can do is to improve soil quality that can slow the global warmimg. A new study finds that well-established, low-tech land management practices like planting cover crops, optimizing grazing and sowing legumes on rangelands, if instituted globally, could capture enough carbon from the atmosphere and store it in the soil to make a significant contribution to international global warming targets. When combined with biochar and aggressive emissions reductions, the sequestered carbon in agricultural and grazing lands worldwide could lower global temperatures by nearly half a degree Celsius.
