1、Substituting partial chemical nitrogen fertilizers with organic

Substituting partial chemical N with organic fertilizer (SP) is an environmentally friendly and sustainable fertilization practice. However, the appropriate rate of SP in rainfed maize cropping systems in semi-arid regions of China is unknown.

2、Combined applications of organic and synthetic nitrogen fertilizers for

Combined applications of organic and synthetic N fertilizers decreased net GWP at field level. The combined application of organic and synthetic nitrogen (N) fertilizers is being widely recommended in China’s vegetable systems to reduce reliance on synthetic N fertilizer.

3、Effects of different combinations of organic fertilizers on the yield

The aim is to provide insights into how different organic fertilizer formulations can enhance vegetable production, improve nutrient content, and promote sustainable agricultural...

4、Nitrogen mineralization from organic fertilizers and composts

Most of the total N in organic fertilizers and composts is in the organic form, which for the most part is not directly plant available. Nitrogen mineralization, the transformation from organic N to ammonium N, is mediated by soil microorganisms.

Best Organic Fertilizers to Boost Nutrient Content

This article explores the best organic fertilizers available, their benefits, and how they enhance nutrient content to support vigorous plant growth. Why Choose Organic Fertilizers?

Long

During nearly 40 years of fertilization, NUE decreased when crops were fertilized with N and potassium fertilizers only, while the NUE increased when multi-nutrient or organic fertilizers were used. The highest NUE was found when 25–30% of the total N input was supplied in organic form.

High Nitrogen Organic Fertilizer (Updated April 4th)

SoilMoist NitroGreen is a 100% organic, high-nitrogen fertilizer (13-0-0) designed to promote vigorous leafy growth and strong stems in vegetables, herbs, and ornamental plants.

Organic nitrogen fertilizers are a critical component in agricultural production, derived from natural organic matter as their nitrogen source. They play a vital role in enhancing soil fertility, improving crop growth environments, and boosting disease resistance in plants. Below is a list of common organic nitrogen fertilizers along with their nutrient content:

1. Chicken Manure (Organic Fertilizer): Widely used, chicken manure is rich in nitrogen (N), phosphorus (P), potassium (K), trace elements, and vitamins. Nutrient content varies slightly by region and poultry breed. On average, each ton contains approximately 3% N, 0.5% P, and 2% K.

2. Cattle Manure (Organic Fertilizer): Another common option, cattle manure has high levels of N, P, K, and trace elements like calcium, magnesium, and sulfur. Regional and breeding differences affect composition. Typically, each ton contains about 2.5% N, 0.6% P, and 2% K.

3. Pig Manure (Organic Fertilizer): Rich in N, P, K, and trace elements such as iron, manganese, copper, and zinc. Composition varies by region and farming practices. On average, each ton provides roughly 2.5% N, 0.7% P, and 2% K.

4. Fish Emulsion (Organic Fertilizer): A high-quality fertilizer containing N, P, K, and trace elements like calcium, magnesium, and silicon. Content differs based on regional and aquacultural conditions. Generally, each ton contains around 1.8% N, 0.9% P, and 1.5% K.

5. Spent Mushroom Substrate (Organic Fertilizer): Waste from edible fungus cultivation, it offers N, P, K, and trace elements like iron, zinc, and copper. Composition depends on cultivation methods. Typically, each ton has approximately 1.5% N, 0.5% P, and 1% K.

6. Green Manure (Organic Fertilizer): Derived from decomposed or incorporated green crops, it contains N, P, K, and trace elements like calcium, magnesium, and sulfur. Variations exist based on climate and crop type. On average, each ton provides about 1.2% N, 0.4% P, and 0.8% K.

7. Soybean Meal (Organic Fertilizer): A byproduct of oil extraction, soybean meal is rich in N, P, K, and trace elements like iron, zinc, and copper. Content varies by processing methods. Typically, each ton contains roughly 1.0% N, 0.3% P, and 0.8% K.

8. Cottonseed Meal (Organic Fertilizer): Used as animal feed, cottonseed meal provides N, P, K, and trace elements like iron, zinc, and copper. Nutrient levels depend on processing. On average, each ton offers about 0.7% N, 0.2% P, and 0.4% K.

9. Peanut Cake (Organic Fertilizer): A byproduct of peanut oil extraction, it contains N, P, K, and trace elements. Regional processing affects composition. Generally, each ton contains approximately 0.5% N, 0.1% P, and 0.2% K.

10. Rapeseed Cake (Organic Fertilizer): A byproduct of canola oil production, rich in N, P, K, and trace elements. Processing methods influence nutrient levels. On average, each ton provides around 0.4% N, 0.1% P, and 0.1% K.

the nutrient content of these organic nitrogen fertilizers varies based on factors such as region, species, and farming practices. For optimal results, select fertilizers tailored to crop needs and soil conditions, and apply them judiciously to ensure healthy plant growth.
