How to Make Organic Nitrogen Fertilizer? Comprehensively Analyzing the Process and Key Points of Making Organic Nitrogen Fertilizer

organic nitrogen fertilizer is one of the important nutrients necessary for plant growth. It can not only provide nitrogen source, but also improve soil quality. With the rise of organic agriculture, more and more farmers and agricultural practitioners began to pay attention to how to make organic nitrogen fertilizer. This article will discuss the production method of organic nitrogen fertilizer in detail, and provide some practical suggestions and techniques.

What is organic nitrogen fertilizer?

Before understanding how to make organic nitrogen fertilizer, you first need to clarify what is organic nitrogen fertilizer. To put it simply, organic nitrogen fertilizer is decomposed by organic matter (such as animal feces, plant residues, etc.) under the action of microorganisms, releasing nitrogen that can be absorbed by plants. Compared with chemical nitrogen fertilizer, organic nitrogen fertilizer not only contains nitrogen, but also provides nutrients needed by other plants, such as phosphorus, potassium and other trace elements. At the same time, it can improve the organic matter content and microbial activity of the soil, and achieve long-term fertilization effect.

Basic raw material for making organic nitrogen fertilizer

the process of making organic nitrogen fertilizer usually requires some common organic raw materials, the following are a few of the main raw materials:

1. animal feces such as cow dung, horse manure, chicken manure, etc., which are rich in nitrogen sources and easy to obtain, are commonly used materials for making organic nitrogen fertilizer.
2. plant residue including straw, leaves, vegetable waste, etc. These materials can effectively release nitrogen sources after composting.
3. Organic wastewater or organic sludge organic wastewater is also rich in nitrogen and other nutrients, suitable for the production of nitrogen fertilizer.

In addition to these basic raw materials, some organic soil amendments (such as humic acid, microbial fertilizer, etc.) can be added to improve the efficiency and quality of organic nitrogen fertilizer.

How to make organic nitrogen fertilizer?

The key to making organic nitrogen fertilizer is to decompose organic raw materials and release nitrogen through the composting process. The specific steps are as follows:

1. Prepare raw materials and mix

animal manure, plant residues and other organic waste are first collected and pretreated. It is usually necessary to cut large pieces of organic matter into small pieces to increase its decomposition rate. Then, these raw materials are mixed in a certain ratio, usually based on the carbon to nitrogen ratio (C:N ratio). The ideal carbon to nitrogen ratio is 25:1 to 30:1.

2. Composting fermentation

the mixed ingredients are placed in a composting area, kept ventilated and humidified. During the composting process, microorganisms break down organic matter, releasing nitrogen and other nutrients. During the fermentation process, it is necessary to periodically turn the pile material to ensure an adequate supply of oxygen and accelerate the decomposition process. The entire composting process usually takes 2 to 3 months, depending on the type of raw material and composting conditions.

3. Screening and preservation of finished products

after the composting is completed, the organic nitrogen fertilizer will turn into a loose black soil-like substance. At this time, it is necessary to screen out the solid particles that are not completely decomposed, leaving the delicate organic fertilizer. Store the screened organic nitrogen fertilizer in a ventilated and dry place to avoid mildew caused by moisture. The finished product can be used directly for soil improvement or fertilization.

How to improve the fertilizer efficiency of organic nitrogen fertilizer?

In the process of making organic nitrogen fertilizer, we should not only pay attention to the nitrogen content, but also improve its fertilizer efficiency. Here are some common ways to improve the efficiency of organic nitrogen fertilizer:

1. adjust the C:N ratio appropriately: Different organic raw materials have different carbon to nitrogen ratio. In order to improve the efficiency of nitrogen release, the C:N ratio can be controlled by adjusting the ratio of different raw materials. Too high or too low C:N ratio will affect the nitrogen release rate.
2. Addition of beneficial microorganisms: In order to speed up the composting process, beneficial microorganisms can be added to the compost, such as thermophilic bacteria, nitrogen fixing bacteria, etc. These microorganisms can promote the rapid decomposition of organic matter and improve the efficiency of nitrogen release.
3. Maintain proper humidity and temperature during the composting process, maintaining a suitable humidity and temperature is essential. Too low humidity will slow down the decomposition process, while too high humidity may lead to an anaerobic environment, which is not conducive to the release of nitrogen.

Summary

the process of making organic nitrogen fertilizer requires a certain skill and patience, but its environmental friendliness and sustainability make it an important fertilizer that cannot be ignored in modern agriculture. In the production of organic nitrogen fertilizer, reasonable selection of raw materials, control of carbon and nitrogen ratio, humidity and temperature in the process of composting can greatly improve the efficiency of fertilizer and nitrogen release efficiency. It is hoped that through the introduction of this article, you can better understand how to make organic nitrogen fertilizer and apply it to actual agricultural production to promote the healthy growth of crops.
