1、Nitrogen Fertilizer for Soybean

Learn more about the Nitrogen needs of today’s higher yielding soybean crops, sources of N supply to the crop, and more.

2、Soybean response to nitrogen fertilizer in different soils

We conducted nine field experiments between 2014 and 2017 over a range of soil types and environments to evaluate soybean yield response to N (as urea) applied at planting, R1, R3, R5, and at all four timings.

3、Soybean Nitrogen Nutrition

Understanding soybean nitrogen (N) nutrition is key to producing high-yielding soybean crops. Soybean Nitrogen Requirement = 4.1 lb N per acre per bushel. Soybean crops require 3 – 4 times the amount of N compared to cereal crops.

4、How Soybeans Fix Nitrogen and Boost Soil Fertility

Explore the intricate science of how soybeans partner with bacteria to transform atmospheric nitrogen into a vital, sustainable soil nutrient.

Optimal Nitrogen Fertilizer Rates for Soybean Cultivation

The aim of this study was to determine the effect of varied nitrogen fertilizer application rates on the dry weight of the separated parts of soybean plants and the whole plant, including the number and weight of root nodules, the potential to reduce atmospheric nitrogen (N2), and the content and uptake of nitrogen.

Nitrogen Management Soybean

An irrigated soybean crop yielding 70 bu/ac would remove about 242 lb N/ac in the grain. The main sources of N that are available to meet the N needs of soybeans are the atmosphere and the soil. In some cases, commercial fertilizers and/or manure may also be used to meet N needs of soybean.

Influence of nitrogen fertilization, seed inoculation and the

Soybean, belonging to legumes, has a specific ability to biological nitrogen fixation, which can be reinforced by seeds inoculation.

Nitrogen application for high yielding soybeans

Nitrogen fertilizers have not traditionally been applied to soybeans. Up to 75% of the total nitrogen needs are supplied through biological N fixation through nodules on the roots.

Nitrogen fertilizer effects on soybean physiology, yield components

To improve management for both yield and seed composition, more insight is needed on how plant physiology links nitrogen fertilization and seed composition outcomes in a variety of soybean production regions.

Soybean, as a crucial oil-bearing crop, requires significant nitrogen during its growth. Nitrogen fertilizer is essential for promoting soybean development, and proper application can effectively enhance yield and quality. Below is a detailed guide on producing nitrogen fertilizer from soybean:

I. Preparation of Nitrogen Fertilizer

1. Raw Material Collection

• Before the planting season, select high-quality, pollution-free soybean seeds as the primary raw material.
• Ensure the chosen seed variety matches local climate and soil conditions to guarantee fertilizer effectiveness and safety.

2. Fermentation Process

• Clean the collected soybean seeds, remove impurities, and air-dry them.
• Mix dried soybean seeds with organic materials (e.g., chicken manure, cow dung) in a specific ratio to enrich nutrient content.
• Place the mixture into a fermentation pit, add water to maintain moisture, and control temperature/humidity to promote microbial (bacteria, fungi) decomposition of organic matter, producing beneficial gases like ammonia.

3. Curing Treatment

• After fermentation, vent harmful gases while retaining nitrogen and other beneficial components.
• Adjust pH to neutral or slightly acidic levels to suit soybean growth needs.
• Sieve and package the cured fertilizer for storage and ease of use.

II. Application of Nitrogen Fertilizer

1. Fertilization Methods

• Before soybean planting, spread the prepared fertilizer evenly on the soil surface and till it into the soil.
• During growth, apply additional fertilizer based on plant health and soil fertility.
• For high-yield fields or low-fertility soils, increase nitrogen usage to support normal growth and yield.

2. Precautions

• Avoid overapplication to prevent soil salinization.
• Balance fertilizer types (e.g., combine with phosphorus, potassium) based on soil and crop needs.
• Follow the "small amounts, multiple applications" principle to avoid fertilizer burn.

III. Storage and Transportation of Nitrogen Fertilizer

1. Storage Conditions

• Store fertilizer in cool, well-ventilated, and dry areas, protected from sunlight and humidity.
• Use airtight containers to prevent nitrogen loss and moisture absorption.
• Regularly inspect fertilizer quality and replace if degraded.

2. Transportation

• Hire professional logistics services for transportation.
• Keep vehicles clean to avoid environmental contamination.
• Use specialized packaging for volatile or corrosive materials.

following these steps enables the production of nitrogen-rich fertilizer tailored for soybean growth. Adhere to scientific application principles to ensure healthy soybean development and stable, high yields.
