How to add organic fertilizer to blended fertilizers
Thread Content
How to incorporate organic fertilizers into blended fertilizers? Generally, organic fertilizers have a high moisture content; during the production of blended fertilizers, coloring and dissolution occur, and such fertilizers cannot be stored for long periods. How should this be addressed?
In my opinion, it should be in accordance with: Blended Fertilizers **Standard GB21633-2008
Organic fertilizers cannot be mixed with compound fertilizers; according to the standards for organic fertilizers, the moisture content cannot meet the requirements. Even if the moisture content is within the acceptable range, severe consequences can occur if it gets damp
Personally, I think it’s possible to add organic matter, but once that is done, the product can no longer be considered a mixed fertilizer. It is necessary to follow the GB18877 standards: the organic fertilizers added should have a particle size similar to that of the main ingredients, and their moisture content and hardness must also be carefully controlled. There are many mixed fertilizers containing organic matter available on the market, and the market for such products is good. It’s best to produce goods based on demand, in order to avoid any adverse effects later on
For organic-inorganic fertilizers, the organic matter content must reach 20% (on a wet basis), with the total nutrient content being greater than or equal to 15%. Experiments conducted in the original unit showed that under these conditions, it is very difficult to achieve a total nutrient content of over 20%. So it is not applicable. Previously, organic and inorganic fertilizers were added to mixed fertilizers (provided that the moisture content was very low, around 2%). At first, this seemed fine, but over time, as the organic and inorganic fertilizers absorbed moisture, they stained the mixed fertilizer; moreover, part of them dissolved. As for using organic fertilizers with a high moisture content, there’s no need to even mention it – they would be ruined after just two days. That’s why organic fertilizer cannot be added to blended fertilizers.
:)The moisture content of the organic and inorganic materials you’re using is too high; I’ve seen values around 1% for organic and inorganic components
This problem does not occur if the organic fertilizer is dried before being mixed in
Is the main idea of the poster: using by-products similar to those from monosodium glutamate factories as fillers, as a substitute for urea? The applicable standard should be: Standard GB21633-2008 for blended fertilizers. Organic fertilizers are prone to absorbing moisture, and coloring as well as dissolution are basically inevitable. Adding a small amount of such organic fertilizer does not necessarily lead to significantly better results in the fields; its main purpose is to provide an additional selling point. There are advantages and disadvantages, so it’s best to emphasize its positive aspects.
