What is organic matter in fertilizer? What are the types of organic matter in fertilizer?

Do you know the selection and application technology of organic matter fertilizer? if you don't know, then take a look at this article and understand it. Only in this way can we fertilize the crops better.

Selection according to soil conditions

According to the analysis of soil organic matter content in soil sampling and improvement field, it can be determined that if the soil organic matter content is less than 1%, the organic fertilizer rich in organic matter should be selected and its price should be considered before it can be applied in large quantities. If the soil organic matter content is more than 3%, it should be applied appropriately except in the gravel land, in terms of economic benefits. Planting green manure crops during fallow and leisure is the most economical and effective method.

It is necessary to understand the characteristics of organic fertilizer.

The organic fertilizers made from composting and ripening can be divided into two types: easy decomposition type and difficult decomposition type. The former is mainly composed of livestock manure, animal waste and oil meal, with less fiber and high contents of nitrogen, phosphorus and potassium. Its nutrients are decomposed and released quickly in the soil. The latter is made of rice, bark, sawdust and crop residues, which is rich in fiber, but has less nitrogen, phosphorus and potassium, and decomposes slowly in soil, so it is suitable for improving soil physiology and promoting soil microbial activity. so that the roots of crops have a good growth environment.

According to crop types and fertilization characteristics

The crops with larger plants and longer growth period need more fertilizer, and the organic fertilizer applied as base fertilizer for short-term crops should choose those with high maturity, and the nutrient supply, especially nitrogen fertilizer, should be adequate. If long-term crops should pay attention to the improvement of soil properties, promote root activation and cooperate with various stages of growth and differentiation, and regulate nutrient supply.

According to the topographic and environmental conditions

The application of organic matter fertilizer should carry out three-dimensional fertilization, dig ditches and holes, and backfill the soil. If the cultivated land is gravel soil due to manpower can not dig ditches to apply, it is better to choose bulk or granular organic fertilizer, liquid organic fertilizer can be applied by sprinkler irrigation.

Pay attention to quality

If organic matter fertilizer is not fermented, it is easy to continue to ferment in the soil after application, resulting in substances harmful to crop roots and breeding pathogens. Organic fertilizers sold in the market should pay attention to the content of heavy metals, such as livestock manure often come from feed additives, such as long-term application of copper and zinc will cause the accumulation of heavy metals, should be carefully selected.

Cooperate with water management

Sprinkler irrigation facilities should be set up in the orchard to timely adjust the supply of water so as to maintain a suitable state of soil moisture, which is conducive to microbial activity, decompose compost and release nutrients, benefit crop roots to absorb nutrients, and improve the utilization rate of compost nutrients.
