1、Enzymatic fermentation of rapeseed cake significantly improved the soil
Rapeseed cake is an important agricultural waste. After enzymatic fermentation, rapeseed cake not only has specific microbial diversity but also contains a lot of fatty acids, organic acids, amino acids and their derivatives, which has potential value as a high-quality organic fertilizer.
2、Enzymes and microorganisms jointly promote the fermentation of rapeseed
However, as a kind of fertilizer, rapeseed cake is mainly applied directly, which is difficult to give full play to its best fertilizer efficiency, resulting in the shortcomings of high cost and slow fertilizer effect.
3、Spontaneous and enzymatic fermentation of rapeseed cake for broiler
Therefore, the present study was conducted to investigate the effect of partial replacement of SBM with untreated or fermented rapeseed cakes (with or without enzymes) on growth performance and nutrient digestibility in broilers.
4、Enzymes and microorganisms jointly promote the fermentation of rapeseed
However, as a kind of fertilizer, rapeseed cake is mainly applied directly, which is difficult to give full play to its best fertilizer efficiency, resulting in the shortcomings of high cost and slow fertilizer effect.
Which cake fertilizer has good fermentation effect?
It is similar in shape to bean cake and rapeseed cake, and its fertilizer effect is almost the same as bean cake. Peanut bran contains about 6.3% nitrogen, about 1.2% phosphorus, and about 1.3% potassium.
Enzymes and microorganisms jointly promote the fermentation of rapeseed
In order to improve the conversion rate of rapeseed cake, we studied the physicochemical properties, the structure of microbial communities, and the composition of metabolites in rapeseed cake after enzymatic fermentation.
Rapeseed Cake Organic Fertilizer Production Line: Turn Agricultural
Rapeseed cake, a byproduct of oil extraction, is rich in nitrogen (4–5%), phosphorus (1–2%), and potassium (1–1.5%), making it an ideal raw material for organic fertilizer production.
Effect of Integrated Use of Rapeseed Cake, Biochar and Chemical
The results showed that the conjunctive application of mineral fertilizers with rapeseed cake (NPK + RC) resulted in significant (p < 0.05) reductions in soil penetration resistance (14.8%) and bulk density (8.7%) and improvement in porosity (9.9%) compared to the control.

After enzymatic fermentation, rapeseed cake not only has specific microbial diversity but also contains a lot of fatty acids, organic acids, amino acids and their derivatives, which has potential value as a high-quality organic fertilizer.
(PDF) Enzymatic fermentation of rapeseed cake significantly improved
In this study, we aimed to elucidate the effect of enzymatic rapeseed cake fertilizer on the soil of tea tree, and to reveal the correlation between rhizosphere soil microorganisms and...
Fermented rapeseed cake is an organic fertilizer primarily composed of proteins, fats, and carbohydrates derived from rapeseed cake. During fermentation, these organic compounds are broken down into simpler substances such as amino acids, sugars, and fatty acids, which can be absorbed by plants to promote growth and development.
1. Definition of Potassium Fertilizer
Potassium fertilizer contains potassium elements and serves to enhance soil water retention, strengthen crop root systems, and improve photosynthetic efficiency. It also optimizes soil structure, aeration, and permeability, thereby supporting plant growth.
2. The Role of Fermented Rapeseed Cake
During fermentation, microorganisms decompose organic matter in rapeseed cake into simpler compounds (e.g., amino acids, sugars, fatty acids), which improve nutrient uptake by plants. Additionally, beneficial microbes like lactic acid bacteria and yeast are produced, enhancing soil fertility and environmental health.
3. Relationship Between Fermented Rapeseed Cake and Potassium Fertilizer
While fermented rapeseed cake boosts soil fertility, this effect arises from improved soil structure and aeration rather than direct potassium supplementation. Thus, it cannot replace conventional potassium fertilizers.
4. Applications in Agriculture
Fermented rapeseed cake is widely used in agriculture:
- As a direct organic fertilizer to enrich soil and improve water retention.
- As a base or topdressing fertilizer to stimulate crop growth.
- In bio-fertilizer production to further enhance soil ecology.
5. Impact on Soil
Fermented rapeseed cake affects soil in the following ways:
- Soil Structure Improvement: Microbial activity enhances aeration and permeability, promoting root development.
- Fertility Boost: Decomposed organic compounds increase nutrient availability for plants.
- Pest Reduction: Microbial competition suppresses pathogenic bacteria and pests.
6. Environmental Impact
Fermented rapeseed cake benefits the environment by:
- Reducing Pollution: Minimizing waste through microbial decomposition.
- Energy Savings: Lowering energy consumption via natural fermentation processes.
- Ecological Protection: Improving soil health and reducing chemical reliance.
Fermented rapeseed cake is an organic fertilizer that enhances soil structure, fertility, and pest resistance. While it cannot substitute for potassium fertilizers, it plays a vital role in sustainable agriculture. Its environmental benefits make it a valuable tool for eco-friendly farming practices.
