 This is the VOA Special English Agriculture Report. North Kivu is a war-torn province that used to be called the bread basket of the Congo. Now, some farmers are being trained to increase their productivity with fertilizer. The International Fertility Development Center is supporting the project. The IFDC is a non-profit group based in the United States. The project includes planting trees. Trees help prevent the loss of soil through erosion. They also provide charcoal for fuel and they provide fertilizer in the form of leaves. Other farmers are experimenting with chemical fertilizer. The farmers use a mixture of chemical and organic fertilizer. They also use improved seed. They say they have succeeded in growing three or four times as much maize, rice, beans and potatoes. The fertilizer costs around a dollar and thirty cents a kilo. But workers from the IFDC say if it triples a yield of potatoes, for example, it means twice the profit. Farmer Adrian Congale says the new methods promoted by the group could be a solution to ethnic conflicts in the Kivu region. Fertilizer brings peace, he says, because more people can earn a living from the soil. One of the trainers, Sandra Kavira Kawise, says fertilizer can even save marriages. She says in one area many of the men had left their wives and gone to work in the mines. Then their wives started using fertilizer and their yields of rice tripled. The IFDC has found that when the men work with the women, the harvests are nine tons a hectare compared with six tons when the women work alone. Dutch scientist Hank Bremen designed the fertilizer project. He says the Democratic Republic of Congo uses less chemical fertilizer per hectare than any other country. Mr. Bremen suggests that one reason is a lack of government policy. Another is the influence of donors and international non-governmental organizations that for about 20 years were against more intensive ways of farming. Edwige Mungwana Kavor is a local agronomist who works for Mercy Corps, an NGO. She says she is not against adding chemical fertilizer to organic matter, but she says land can become dependent on chemical fertilizers and the chemicals can pollute groundwater. Hank Bremen agrees that farmers should mix the fertilizer with organic fertilizer, but he says there is a much bigger risk from soil erosion in the Kivu region. Farmers groups have welcomed a promise from the DRC government to end taxes on fertilizers. Those taxes are some of the highest in Central Africa. For VOA Special English, I'm Mario Ritter.
