Gaotai County has vigorously carried out the research and demonstration and promotion of soil testing and formula fertilization technology, which has effectively played the role of a "navigator" for the scientific fertilization of the masses, effectively promoted the stable increase of agricultural production and enhanced the stamina of agricultural development.
In Xu Sanwan Village, Xinba Town, Gaotai County, the growth of seed corn is gratifying, and the county supply and marketing association is holding a corn soil testing formula fertilization test demonstration and yield improvement results display on-site observation and exchange seminars here. This year, in order to open up the "last kilometer" of agricultural services, the Gaotai County Supply and Marketing Association relies on 10 crop hospitals in the county to hire agricultural technical personnel as crop doctors, go deep into the fields, and provide information consultation, new technology training and promotion, soil testing and formula fertilization and other services for the farmers, and jointly with the provincial agricultural materials company in Xu Sanwan Village, Xinba Town, and Fruit Tree Village, Camel Town, to set up water and fertilizer integration test fields, do a good job in data collection, adjust fertilization methods according to local conditions, and provide strong technical support for corn harvest. It relieved the peasants of their worries about farming.
"According to the solutions provided by this soil testing formula, the chemical fertilizer I use is more cost-effective than ordinary ones, and it may reach 300 yuan per acre, and the yield of mine is 110 kilograms higher than that of other people." Zhao Hai, a villager in Guoshu Village, Camel Town, Gaotai County, said.
Gaotai County has carried out 8 field experiments and 13 times around the implementation of projects such as improving the quality of cultivated land, reducing and increasing the efficiency of chemical fertilizers, integrating water and fertilizer, and replacing chemical fertilizers with organic fertilizers. Through the development of saline-alkali land improvement and soil fertilization technology, the county has driven the implementation of soil testing and formula fertilization area of more than 562,000 mu, and the technical coverage rate has reached more than 90%.
