Chemical Fertilzers Do Ruin the Soil--India

Yesterday's (February 22, 2010) Wall Street Journal reports that overuse of high nitrogen urea chemical fertilzers has so degraded India's farmland that the country is unable to feed itself again. Popularized during the Green Revolution of the 1960s and 1970s, fertilizers helped boost crop yields and transformed India into a nation that could feed itself. But now their overuse is degrading the farmland, WSJ reports.

Here are the first three paragraphs of the online posting.

"Green Revolution in India Wilts as Subsidies Backfire.

By GEETA ANAND

SOHIAN, IndiaIndia's Green Revolution is withering.

In the 1970s, India dramatically increased food production, finally allowing this giant country to feed itself. But government efforts to continue that miracle by encouraging farmers to use fertilizers have backfired, forcing the country to expand its reliance on imported food.

India has been providing farmers with heavily subsidized fertilizer for more than three decades. The overuse of one typeÂureaÂis so degrading the soil that yields on some crops are falling and import levels are rising. So are food prices, which jumped 19% last year. The country now produces less rice per hectare than its far poorer neighbors: Pakistan, Sri Lanka and Bangladesh."

The problem has been encouraged by a government policy that subsidizes the cost of urea. The WSJ article mentions that the urea fertilizer manufacturers are a powerful lobby and the government does not have the political will to stop the subsidies, and this encourages use of the cheap chemical nitrogen. The effect of this is as yields drop, farmers use even more cheap urea to try to increase yields, causing food production to continue to drop, food imports to increase and food prices to rise.

According to the article, the degrading of India's farmland because of urea chemical overuse has been confirmed by multiple studies.

Here is some sad evidence that there is a long term negative impact from the use of synthetic chemical nitrogen. Overuse of high nitrogen chemical fertilizers will produce a short term boom and then a long term disaster.
