China's scientific fertilization coverage has reached 30%
By the end of 2007, China had achieved a 30% coverage rate of scientific fertilization on its arable land, according to Gao Xiangzhao, head of the Fertilization Division at the Agricultural Technology Extension Center under the Ministry of Agriculture. He shared this information during the International Seminar on Research and Development of High-yield and High-efficiency Industries for Hybrid Rice.
Gao emphasized that despite only accounting for 9% of the world’s arable land, China produces 25% of the global agricultural output, feeding 22% of the world's population. This is a significant accomplishment. However, he also pointed out that China uses 35% of the world’s chemical fertilizers, leading to issues such as low fertilizer efficiency and imbalanced application practices.
Starting from 2005, the government launched a multi-year initiative, investing 200 million yuan in the first year, followed by 500 million and 900 million yuan in the next two years. This funding supported the establishment of 1,200 soil testing and fertilization project counties across the country.
According to data from the Ministry of Agriculture, scientific fertilization has proven effective in boosting crop yields and farmer incomes. In pilot counties, grain output increased by 5% per mu, fertilizer use efficiency improved by 3%, and income per mu rose by over 25 yuan. Notably, in regions like Hubei, Jiangsu, and Shandong, where excessive fertilizer use was common, there has been a noticeable decline in nitrogen fertilizer consumption.
In 2008, the Ministry of Agriculture planned to expand the promotion of soil testing and formula fertilization. The program would not only increase its geographical reach but also extend its focus from food crops to cash crops. Additionally, training programs would target large-scale farmers, technology demonstration households, and key farming families, aiming to bring more farmers into the fold of scientific fertilization practices. This move reflects a broader commitment to sustainable agriculture and improved productivity.
