See raw materials to determine the quality of organic fertilizer
The planting of vegetables is inseparable from the organic fertilizer. The quality of the organic fertilizer is related to the output of the whole growing season of the vegetable. Therefore, it is very important to choose a high-quality organic fertilizer. Farmers need to know how to choose organic fertilizer based on raw materials.
As the saying goes, "compound fertilizer to see nutrients, organic fertilizer to see raw materials" is the reason. At present, there are many types of raw materials used in organic fertilizers on the market, and the quality is also uneven. There are many different effects. Commonly used humic acid, urban sludge, paper mill sludge, lignin, biochemical pharmaceutical waste and cakes, etc., humic acid raw materials have a certain role in the improvement of the soil and roots, but the beneficial bacteria in the soil The support effect is minimal, and therefore it performs generally in fertilizer quality. The urban sludge and paper mill sludge are high in heavy metal content. If there is any omission in the treatment process, it will cause artificial pollution of the crop and result in loss of income. Although the organic fertilizer of lignin type raw material has a high content of organic matter, it is difficult to decompose the lignin in the soil, and it can be imagined to use it as a fertilizer. In recent years, organic fertilizers made by biodegrading the solid wastes of biochemical pharmaceutical plants by microbial methods have shown good results in the actual production of agriculture. This is due to the use of biochemical pharmaceutical plants for the production of antibiotics. Both starch and pancake ingredients are added. These late biochemical wastes were often used for processing feed in the previous years. In view of food safety factors, they were later banned from being added to feed by the state. However, the components in these wastes have very high nutritional value, and they are very effective when used as organic fertilizers after decomposed treatment. Direct use of pancake to produce organic fertilizer, due to the high cost of raw materials, the market is currently very small, and the identification of "cardamom organic fertilizer" products in the end whether there are pods, how many pods contain, we can hardly judge.
When selecting the organic fertilizer, it is possible to select a good organic fertilizer from the raw materials. The so-called “good raw materials can produce good fertilizer†is the reason.
Farmers can choose the right organic fertilizer according to the situation. It is not possible to measure or choose a kind of organic fertilizer simply based on the price. In addition, it is recommended that when growing vegetable crops such as melons and tomatoes, the vegetable farmers should not simply use commodity organic fertilizers, and can invest in farmyard manure and commodity organic fertilizer at a ratio of 1:1, which can prevent commodity organic fertilizers from being effective. Shortcomings. Supplementing beneficial microorganisms is also crucial when changing.
