Agricultural Salt (coarse salt) is different from salt (commonly known as salt), and its main component is sodium chloride. It also contains magnesium, potassium, sulfur, and a small amount of nutrients needed by crops such as boron and iodine. Although it is not a direct fertilizer for crops, as long as it is properly applied, it will have a good effect on some of the sour-sodium crops. If agricultural salt is applied to crop plots such as beets and celery, it will not only increase production, but also improve and improve the quality of hi-sodium crops such as sugar beets and celery. However, paddy fields cannot be used for a long time and agricultural salt is applied separately year after year. Otherwise, sodium ions will destroy the good structure of the soil, causing cracks in the dry slats, rotten and sticky when wet, poor permeability and poor ploughability. Therefore, the application of agricultural salt can only be used as an auxiliary fertilization method. It must be applied on the basis of the application of organic fertilizers, and it can not be applied more or for consecutive years.
The method of applying agricultural salt: Generally, the combination of agricultural salt and human manure and other organic fertilizers is used as base fertilizer, and rooting can also be applied during transplanting, and direct fertilizer can also be used directly. The application of 5-8 kilograms per acre is appropriate. .
