Guangdong vigorously promotes soil testing and formula fertilization

In order to promote soil testing and formula fertilization, the Guangdong Provincial Department of Agriculture adopted a model of class demonstration and whole village advancement. It established 42 provincial demonstration areas of 10,000 mu. In the critical period of fertilization, training classes were organized, on-site meetings were held, and soil testing formulas were popularized. With knowledge of fertilization and full use of the driving force in the demonstration area, farmers can see “model field” everywhere, and knowledge of soil testing formulae can be obtained everywhere, and they are actively participating in the field of soil testing and fertilizer application.

In the course of the whole construction system to promote soil testing and formula fertilization, the lead effect of the leading enterprises will be brought into full play. Taking Huidong as an example, there are 66 leading agricultural enterprises in Huidong County. The local government cooperates with enterprises in land acquisition and field experiments to jointly guide farmers to apply soil testing and fertilizer application techniques. In recent years, the use of formula fertilizer in Huidong County of Guangdong Province has reached 1.7 million mu, and the average annual increase in efficiency has reached 133 yuan.

In addition, the types of farmland in Guangdong Province are diverse. To satisfy different planting needs, the local government has explored a formula fertilizer supply model of “government soil testing, expert recipes, and farmers building their own private fertilizers”. The agricultural sector and the designated producers of formulated fertilizers share soil testing data. Prior to the annual spring plowing or winter seasons and other key production seasons, the agricultural sector organizes experts to formulate formulas for measuring soil formula fertilizers in all counties, and enterprises produce fertilizer formulation information released by the agricultural sector. Processing, according to the location of the plots and the types of crops, providing personalized services to farmers on demand, with the amount.

At present, 95 of the 105 counties in Guangdong Province have promoted soil testing and formulated fertilization. Since the Central Document No. 1 proposed to popularize soil testing and formula fertilization in 2005, Guangdong Province has designated soil testing and formula fertilization as the first task of the province's agricultural boosting technology each year, and has established a special fund for soil testing and formula fertilization for agricultural land of 10 million yuan each year. . In the past seven years, the province has promoted 208 million mu of soil testing, formulated fertilizer, and cost-effectiveness of 162 million yuan.

“The next step also plans to use specialized carriers such as farmer cooperatives to establish specialized socialized agrochemical service organizations, explore service models of 'government surveying soil, expert formulas, enterprises' supply of fertilizers, and farmer applications', and provide farmers with integrated surveying and distribution. Integrated agricultural and chemical services for farmers and farmers help fertilize the soil,” said Zhang Yucan, deputy chief of Guangdong Fertilizer Station.
