In March, as the waters warm, a surge of spring plowing sweeps in. Recently, reporters learned from an investigation in Jiangxia District that a growing number of farmers are willing to apply organic fertilizer.Artikel berasal dariFOFCC-http://fofcc.org.cn/ms/11291/
Yesterday, in Laoshi Village, Zhengdian Subdistrict, Jiangxia District, three transport vehicles were delivering dark biogas slurry to greenhouses. Villager Cao Qiulian said that everyone is buying organic fertilizer, and the village has purchased at least more than 1,000 tons over the past month or so. “In previous years, pig manure required paying out of one's own pocket for transport, and even when given away for free, one had to speak nicely to persuade others to take it; now, many farmers are willing to bear the transport costs on their own initiative, and sometimes it can even sell for 20 to 30 yuan per ton.” Yang Jie, head of the Jiangxia Xianqiao Pig Farm, said, “This situation is similar at more than 40 large pig farms across the district.”Artikel berasal dariFOFCC-http://fofcc.org.cn/ms/11291/
Even more sought after than pig manure is chicken manure. Xu Hong, chairman of the Wuhan Gangfa Poultry Farming Cooperative, introduced that the cooperative's 200 farming households collect about 10,000 tons of chicken manure each year, with no worry about finding a market, and the price per ton has risen from 130 yuan last year to 200 yuan, becoming a new avenue for farming households to increase income.Artikel berasal dariFOFCC-http://fofcc.org.cn/ms/11291/
According to statistics from the district's agricultural department, since this year's Spring Festival, major livestock and poultry farms across the district have sold more than 50,000 tons of biogas fertilizer and dried pig and chicken manure, double the amount for the same period last year and more than a fivefold increase compared with three years ago.Artikel berasal dariFOFCC-http://fofcc.org.cn/ms/11291/
Chemical fertilizer gradually “no longer running the household”Artikel berasal dariFOFCC-http://fofcc.org.cn/ms/11291/
Behind the strong sales of organic fertilizer, what is the secret?Artikel berasal dariFOFCC-http://fofcc.org.cn/ms/11291/
Wang Zuoxiang, chief agronomist of the Jiangxia District Agriculture Bureau, believes that this reflects that farmers have begun to change their production concepts and are gradually bidding farewell to the era of “chemical fertilizer running the household.”Artikel berasal dariFOFCC-http://fofcc.org.cn/ms/11291/
At present, bagged organic fertilizer on the Jiangxia market costs more than 800 yuan per ton, while chemical fertilizer costs more than 2,000 yuan per ton. Calculated on the basis that one ton of organic fertilizer covers 2 mu of land and one ton of chemical fertilizer covers 10 mu of land, the input cost of organic fertilizer is relatively higher.Artikel berasal dariFOFCC-http://fofcc.org.cn/ms/11291/
However, for ordinary vegetables, using only chemical fertilizer yields about 1,000 kilograms per mu, while using organic fertilizer can reach 2,000 kilograms per mu. For rice, adding organic fertilizer can increase yield by 20% to 30% per mu; if relying on chemical fertilizer year after year, it will lead to soil acidification, water and soil pollution, and yields will not increase but instead decline.Artikel berasal dariFOFCC-http://fofcc.org.cn/ms/11291/
In earlier years, Jinkou Subdistrict once planted garlic on a large scale, and some farmers were accustomed to using too much urea, but year after year, organic matter and trace elements in the soil gradually dwindled, the garlic leaves grew yellower and yellower, and the garlic bulbs grew smaller and smaller. When farmers in Tudi Tang grew watermelons, some liked to use too much chemical fertilizer, which resulted in soil compaction and actually produced “iron watermelons,” with rinds about one cun thick.Artikel berasal dariFOFCC-http://fofcc.org.cn/ms/11291/
Wang Zuoxiang stated that many years of farming practice have gradually made farmers realize that excessive use of chemical fertilizer is ultimately not a long-term solution. He gave an example, saying that people today no longer eat indiscriminately out of hunger; for the sake of health, they pay attention to “organic” and “pollution-free” when eating food. Crops also have life—how can they eat “rich meat dishes” all year round? Organic fertilizer is precisely the “organic food” for soil and crops, and its popularity should be the natural choice of the agricultural ecological chain.Artikel berasal dariFOFCC-http://fofcc.org.cn/ms/11291/
Data show that in recent years, the total grain output of Jiangxia District has increased year by year, and the total vegetable output has remained basically stable, but the total amount of chemical fertilizer used, after peaking in 2007, has declined year by year from 97,000 tons to 82,000 tons last year.Artikel berasal dariFOFCC-http://fofcc.org.cn/ms/11291/
Sweet vegetables, fragrant rice, warmer walletsArtikel berasal dariFOFCC-http://fofcc.org.cn/ms/11291/
“Growing lotus roots with chemical fertilizer yields 2,000 kilograms per mu, and after being dug out they can be stored for half a month; growing lotus roots with organic fertilizer yields 3,000 kilograms per mu, and after being stored for a month they are still very fresh,” said Hu Tao, general manager of Yishanwan Ecological Agriculture Co. in Fasi Town, unable to contain his delight. The lotus roots grown by the company using organic fertilizers such as biogas slurry have been exported to Canada.Artikel berasal dariFOFCC-http://fofcc.org.cn/ms/11291/
Wang Zuoxiang introduced that vegetables and rice grown with organic fertilizer are relatively sweeter and more fragrant. For example, the Hongshan caitai grown with organic fertilizer in Laoshi Village is sweeter and crisper than ordinary caitai. Last year's warm winter caused Wuhan's caitai to grow explosively, and in many places caitai were sold cheaply for one mao and still attracted no buyers, but the caitai from this village was highly favored by consumers. In addition, the more than 1,000-mu organic rice base established by Guizi Rice Industry Company uses organic fertilizer throughout, and the rice it produces has been gaining an increasingly strong reputation and is in short supply.Artikel berasal dariFOFCC-http://fofcc.org.cn/ms/11291/
The high yield and high quality brought by organic fertilizer have provided support for increasing farmers' income. Last year, Jiangxia District planted 660,000 mu of rice, and organic fertilizer accounted for 30% of the total fertilizer used; among the 230,000 mu of vegetables newly sown this spring, the promoted area of organic fertilizer has already reached more than 100,000 mu. Since 2007, the district's per capita net income of farmers has grown from 5,386 yuan to 8,317 yuan last year.Artikel berasal dariFOFCC-http://fofcc.org.cn/ms/11291/
