The days of intensive hand labor and corn air-drying on China’s rural roads may be ending, as a major modernization effort changes traditional Chinese agriculture and the competitive outlook for corn production and use.

Kevin Rempp, Montezuma, Iowa, a grower who chairs the Iowa Corn Promotion Board, saw the inefficiencies of the traditional Chinese system on a U.S. Grains Council crop tour.

“The plots were about three-fourths to two acres maximum per farmer, so a field of 80 to 100 acres could have many, many plots,” he recalls.

“With such small plots, 75-80% of the corn was planted by hand. We saw very good ear sizes but a limited population; rarely more than 15,000-18,000 plants per acre.”

It’s almost impossible to compare China’s corn production to U.S. competitive efficiencies because the differences are so great, but one measure Rempp cites is yield per acre.

US and China corn production

Chinese yields have increased 44%, from 62.7 bushels per acre 25 years ago to 90.6 bushels/acre this market year, but still lag far behind U.S. productivity. The big increase in production that allowed China to vie for world export markets in recent years reflected increased harvested acres more than yield improvements.

“Even though they are increasing their production, it’s increasing slowly,” Rempp says. “Their usage is also growing. It will continue to outpace their corn production, and they will continue to be very large importers of corn.

“I think major improvements in Chinese corn production will take many years.”

While modernization is likely to mean better efficiency and higher corn yields, other aspects of the change may also halt the increases in corn acreage.

More efficient land use may also be on the horizon, as small plots are increasingly rented to produce larger units, and the government takes steps to secure land tenure.

Chinese tenants farm up to 20% of China’s agricultural land.

Such changes will take time, however. In the short term, the biggest potential for major yield increases could come from a decision to adopt genetically modified seed technology.

That could increase output by almost 800 million bushels, but there are significant obstacles to GMO adoption, beyond even China’s political battles over the technology.
