In recent years, an increasing number of merchants have begun to promote various functional fertilizers, such as microbial bacterial fertilizers, amino acid fertilizers, chitin fertilizers, humic acid fertilizers, seaweed fertilizers, yeast metabolites, enzymatic calcium from Marine organisms, fish peptide proteins, etc., as well as various reagents for plant conditioning or soil activation, such as HB-101, wood vinegar liquid, etc.
Their functions are basically all in crop production, which can be summarized as improving soil quality, promoting root and leaf growth, enhancing stress resistance, increasing yield and improving quality.
To understand these functional fertilizers, first of all, we should know what works in these things. The main substances that have an effect on plants mentioned above are as follows:
1.The nutrients provided to plants include macronutrients such as nitrogen, phosphorus and potassium, as well as various trace elements.
2. Fulvic acid/humic acid, both of these substances are organic acids. Strictly speaking, fulvic acid is a type of organic acid with a very small molecular weight among humic acids. It can be directly absorbed by plant roots or absorbed by leaves through stomata, both of which can promote plant growth. Here, we need to briefly talk about composting. In fact, during the composting process, large-molecule organic matter is decomposed into small-molecule organic matter, most of which is humus. Among humus, there is fulvic acid mentioned earlier, as well as some others like humic acid, all of which belong to humic acid.
So, in regular organic fertilizers and even in the soil, they all exist; it's just a matter of the content. Here we are all talking about biochemical fulvic acid. It is actually a different thing from the mineral fulvic acid we often buy.
3. It is sugars, such as dextran and mannan, which can act as natural inducers to increase the sugar and vitamin C content in crop fruits, thereby enhancing the crop's resistance. This substance is relatively abundant in yeast metabolites.
4. Various amino acids. We all know that proteins are composed of amino acids. As a kind of small-molecule acid, amino acids are more easily absorbed by plants. Since proteins are made up of amino acids, most organic fertilizers actually contain many types of amino acids to varying degrees. In terms of content, it is definitely much higher in amino acid fertilizers, fish peptide proteins, seaweed fertilizers and yeast metabolites than in ordinary organic fertilizers.
5. There are various other organic acids, such as acetic acid, lactic acid, citric acid, jasmonic acid, and malic acid. On the one hand, they can regulate the soil's pH level, and on the other hand, they also have some effects in enhancing soil stress resistance. Many acids are substrates for various metabolic pathways during the growth process of plants.It is polypeptides.
In fact, polypeptides are composed of amino acids. Many small molecule polypeptides are natural active substances that can promote root growth, facilitate the formation of enzymes in plants, and enhance their stress resistance. This is also one of the reasons why some fertilizers can alleviate stunted seedlings!
