The current farming is just around the corner, which is the peak season for the sale of agricultural products and the purchase of agricultural materials by farmers. The scientific purchase of chemical fertilizers is crucial for achieving high crop yields. So what should farmers pay attention to when purchasing fertilizer?
1, try to use domestic and provincial famous brands, problems and easy to investigate and claim.
2, select the soil testing formula fertilization designated products, formula fertilizer has a good target for the region and crops.
3, to avoid, reduce the use of some small fertilizers, such as long-acting ammonium bicarbonate, potassium sulfate, zinc sulfate and so on.
4, do not blindly pursue low-priced products, some low-priced products are often low quality raw materials, nutrient effectiveness is poor.
5. Do not choose products that take organic matter, calcium, magnesium, sulfur, and chlorine into nutrients, and prevent the deferment of the crop during the growth period due to insufficient total effective nutrients.
6. Look at the “three certificates†on the packaging label: select the product with the registration number, execution standard and production license number.
7. Look at the inspection report, registration certificate, and request a credit card and invoice.
