Kazakhstan's 2012 drought and high temperatures cut the country's wheat harvests by more than half from 2011 output, but wheat under zero-tillage practices gave up to three times more grain than conventionally cultivated crops. Two million hectares are currently under zero tillage, making Kazakhstan one of the top-ten countries for conservation agriculture and helping to avoid severe wheat shortages.

"If no-till practices had not been used this period of drought, we would have gotten nothing. It would have been an absolute catastrophe," says Valentin Dvurechenskii, Director General of the Kostanay Agricultural Research Institute in Kazakhstan, giving his verdict on the 2012 wheat crop.

After farmers planted their wheat in April, Kostanay—the country's main wheat growing region—went two months without rain. Making matters worse, daily temperatures were several degrees above normal. At the time, farmer and Director General of the Agrofirm Dievskaya, Oleg Danilenko, echoed the view of peers: "I've been a farmer for 35 years, and I've never seen anything like this." Danilenko said the harsh conditions pointed up the advantages of conservation agriculture, which involves reduced or zero tillage, keeping crop residues on the soil, and rotating crops. "No other results have been nearly as successful."
