Four points for attention in purchasing organic fertilizer
2021/02/17
Organic fertilizer refers to manure, straw and other organic matter (including manure, compost, etc.) used as fertilizer, which is processed into fertilizer containing organic matter by fertilizer production process. Organic fertilizer can improve soil fertility. So what should we pay attention to when buying organic fertilizer?
1. Because the total nutrient content of organic fertilizer is relatively low, the total nutrient content of nitrogen, phosphorus and potassium in some fertilizers on the market is relatively easy to meet the requirements, but the content of organic matter is mostly unqualified.
2. Organic fertilizer is a kind of fertilizer beneficial to processing and production. Therefore, quite a number of small-scale enterprises have carried out the production in a very simple way. It is difficult to guarantee the quality of such organic fertilizer products.
3. Organic fertilizer packaging labels are often misleading. For example, some fake and inferior fertilizers are usually supplied to farmers in the form of organic fertilizers, and there are even fake and inferior fertilizers such as organic urea.
4. As raw materials, animal and plant residues and their excreta are made by strict fertilizer manufacturing process, that is, pig manure, chicken manure, cow manure, etc. are made by fermentation, and harmful substances are removed.
