Kunming Jin Ning whole process monitoring soil strengthening treatment

In order to prevent the acidification of the soil from intensifying, the professional technicians of the Jinning County Agricultural Technology Promotion Center often go deep into the fields to extract soil samples, understand the planting situation of farmers, and make records. The retrieved soil sample must be subjected to many complicated processes such as air drying and screening, and then be tested by the instrument. For the soil showing a ph value of less than 7, the acidification phenomenon can be confirmed.

“The more the land is not growing, the less fertility the chemical fertilizer can only alleviate. The soil is even worse when it is planted in the coming year. What is going on in the end?” Li Ningxi, a peasant in Jinning County, watched as his home’s increasingly “sour” land was guilty of worry. In recent years, the Agricultural Technology Promotion Center of the Jinning County Agriculture Bureau has set up 24 long-term monitoring and positioning points in the whole county for the problem of land acidification in the entire county. It has detected more than 40,000 acres of land where acidification has occurred, and has taken more than 2,200 soil samples. Obtain first-hand information on the land and guide farmers to improve their soil and fertilize properly, effectively delaying the acidification of the soil and ensuring farmers' income from planting.

Jinning County was originally a major planting area for grain crops such as corn and rice. Around 2006, with the declining economic benefits of food crops, farmers planted vegetables, flowers, and other economic crops. As the land cultivation cycle is greatly shortened, the soil fertility is reduced, and the growers blindly use chemical fertilizers, and the use of plastic greenhouses and greenhouses, the direct contact between soil and air, rainwater, and sunlight is blocked, making it possible to start three or four years after the start of 2006. The acidification of the soil in Jinning County was serious.

“We have started soil monitoring since 1998. We have changed from several monitoring sites to the current 24 long-term monitoring sites and random sampling sites to monitor the soil at any time. We have taken different measures to improve the degree of acidification.” Jinning Agriculture Director Wang of the Technology Promotion Center introduced that the establishment of the monitoring site enabled the Agricultural Technology Promotion Center to have a more accurate grasp of the soil conditions in the county, and also provided guidance for the farmers to adapt to the disease and to improve the soil according to local conditions.

In order to prevent the acidification of the soil from intensifying, the professional technicians of the Jinning County Agricultural Technology Extension Center often go deep into the fields to extract soil samples, understand the planting situation of farmers, and make records. The retrieved soil samples are subjected to many complicated procedures such as natural air drying and screening, and then tested by the instrument. For the soil showing a ph value of less than 7, the acidification phenomenon can be confirmed. If there is any arable land on this soil, the technical staff at the center must guide the farmers to carry out soil improvement, rational fertilization, and adjustment of soil pH. The main measure of “resuding acid” is to instruct farmers to use quicklime to adjust the pH, and to eliminate the use of acidic fertilizers. By adding organic fertilizers and biological bacterial fertilizers, using alkaline fertilizers such as foliar spraying and other extra-root fertilizers, effectively delays. And improve the acidification of the soil.
