At present, farming is on the verge of being the peak season for the sale of agricultural products and the purchase of agricultural resources by farmers. The scientific purchase of chemical fertilizers is crucial for achieving higher crop yields. So what issues should farmers pay attention to when purchasing fertilizer?
1, try to use domestic and provincial well-known brands, problems occur to facilitate the investigation and claims.
2. The designated products for soil testing and formula fertilization are used, and the formulated fertilizers are better targeted for the regions and crops.
3, avoid, reduce the use of some small fertilizer species, such as long-acting ammonium bicarbonate, potassium sulfate, zinc sulfate and so on.
4, do not blindly pursue low-priced products, some low-cost products are often of low quality raw materials, poor nutrient availability.
5. Do not choose products that include organic matter, calcium, magnesium, sulfur, and chlorine into nutrients to prevent defertilization of the crop during the growing season due to insufficient total nutrient availability.
6. Look at the “three licenses†on the packaging label: Select the product with registration number, execution standard, and production license number.
7, see the inspection report, registration certificate, request credit card and invoice.
