But a new study casts doubt on biochar's efficacy, finding that using it only improves crop growth in the tropics, with no yield benefit at all in the temperate zone.

This study shows that although miscanthus yield was slightly lower on marginal, low - quality land, a farmer would have an economic incentive to grow miscanthus on the lower quality land first rather than diverting their most productive cropland from growing corn,» said University of Illinois agricultural economist Madhu Khanna who co-authored the study along with a team of economists and environmental and crop scientists from the Energy Biosciences Institute at U of I.

In agriculture, aid and research are helping to boost productivity through targeted interventions aimed at improving crop yields, capturing water for irrigation and providing advice on selling surplus produce.

say it has been predicted that «the average temperature in the semiarid northwest portion of China in 2050 will be 2.2 °C higher than it was in 2002,» and they report that based on the observed results of their study, this increase in temperature «will lead to a significant change in the growth stages and water use of winter wheat,» such that «crop yields at both high and low altitudes will likely increase,» by 2.6 % at low altitudes and 6.0 % at high altitudes... Even without the benefits of the aerial fertilization effect and the anti-transpiration effect of the ongoing rise in the air's CO2 content, the increase in temperature that is predicted by climate models for the year 2050, if it ever comes to pass, will likely lead to increases in winter wheat production in the northwestern part of China, not the decreases that climate alarmists routinely predict.»

Most TreeHugger readers probably a good handle on the concept that large monocropped fields have lesser biodiversity than more mixed cultivation, and that industrial agriculture uses excessive amounts of fertilizer to push crop yields to their maximum, even at the expense of decreasing soil fertility.
