1、Which cake fertilizer has good fermentation effect?

Rapeseed cake contains about 4.6% nitrogen, about 2.4% phosphorus, and about 1.4 potassium, among which the phosphorus content is relatively high. However, the nitrogen content and overall fertilizer effect are not as good as bean cake and peanut cake.

2、Response of peanut (Arachis hypogaea L.) plant to bio

Nitrogen (N) fertilizer has been intensively used to improve peanut productivity. However, the high cost of N fertilizer, and the need for sustainable alternative fertilizer sources have increased the strategic importance of nitrogen fixation (NF). ...

3、Why Does Peanut Planting Require No Nitrogen Fertilizer?

The application of nitrogen fertilizer to peanuts is usually not necessary because they obtain sufficient nitrogen via a beneficial relationship formed with nitrogen fixing rhizobium bacteria.

4、Fermentation approach on phenolic, antioxidants and functional

The aim of the present study was to examine the effect of solid state fermentation on phenolic contents, antioxidants and functional properties of fermented and non fermented peanut press cake by GRAS fungal strain A. awamori.

Is Using Spoiled Peanuts as Fertilizer Considered a Nitrogen Fertilizer

Spoiled peanuts, as a fertilizer, differ in composition and function from conventional chemical fertilizers and therefore cannot be simply classified as nitrogen fertilizers.

Solid

Peanut press cake, an agro-industrial waste provide a solid support for the growth of microorganism to produce different valuable enzymes such as amylase, glucosidase, xylanase, lipase. These enzymes have great attention towards research for their perceived industrial importance and economic profit.

Reduction in Nitrogen Rate and Improvement of Nitrogen Use Efficiency

It is important to quantify nutrient requirements and optimize fertilization to improve peanut yield and fertilizer use efficiency. In this study, a multi-site field trial was conducted from 2020 to 2021 in the North China Plain to estimate nitrogen ...

How to use peanut shells to make organic fertilizer

As a by-product of peanuts, peanut shells are not fully utilized and are discarded or burned as fuel.

How to use Ground Nut Cake Using as Organic Fertilizer

Farmers can apply groundnut cake directly to the soil or mix it with compost to create a balanced organic fertilizer that fosters a thriving ecosystem for plants.

Reduction in Nitrogen Rate and Improvement of Nitrogen Use

It is important to quantify nutrient requirements and optimize fertilization to improve peanut yield and fertilizer use efficiency.

Fermented peanut cake, as an organic fertilizer, is widely used in agricultural production. It is rich in essential nutrients such as nitrogen (N), phosphorus (P), and potassium (K), providing plants with necessary nourishment and promoting crop growth. fermented peanut cake cannot be directly used as a nitrogen fertilizer due to several reasons. The following analysis explores these factors:

1. Low Nitrogen Content in Fermented Peanut Cake

1.1 Slow Nitrogen Release

Compared to fast-release nitrogen fertilizers like urea, the nitrogen in fermented peanut cake is released slowly. This is primarily due to the time required for microbial action to decompose and convert nitrogen during fermentation. Consequently, longer periods are needed to observe significant yield improvements after application.

1.2 Low Nitrogen Use Efficiency

The slow nitrogen release, combined with reduced absorption and utilization efficiency by soil microorganisms, results in low actual nitrogen availability. While fermented peanut cake provides some nitrogen, the amount effectively absorbed by plants is limited, diminishing its economic value as a fertilizer.

1.3 Nitrogen Form Issues

After fermentation, nitrogen in peanut cake mainly exists as ammonium nitrogen (NH₄⁺), which is readily absorbable by plants. microbial activity during fermentation may convert some nitrogen into less plant-available forms, such as nitrate nitrogen (NO₃⁻), further reducing usability.

2. Inadequate Nitrogen Fertilizer Effects

2.1 Short Fertility Duration

Due to slow nitrogen release and inefficient microbial uptake, the fertilizer effect of fermented peanut cake lasts for a shorter period. This requires more frequent applications to meet plant needs, increasing labor and costs for farmers.

2.2 High Sensitivity to Environmental Factors

The effectiveness of fermented peanut cake as a nitrogen source is heavily influenced by soil conditions. Poor drainage, compacted soil, or high pH levels can inhibit microbial activity, reducing nitrogen conversion efficiency and rendering the fertilizer ineffective.

2.3 Unstable Fertility

The slow and variable nitrogen release, affected by multiple factors, leads to inconsistent fertilizer performance. This unpredictability introduces risks in agricultural production, as plant growth may fluctuate uncontrollably.

3. Improper Application Methods

3.1 Overapplication

Excessive use of fermented peanut cake can lead to nitrogen accumulation in the soil, raising groundwater levels and causing eutrophication. Additionally, overapplication may degrade soil structure, reducing its water-holding capacity and nutrient retention.

3.2 Timing Misalignment

The effectiveness of fermented peanut cake depends on application timing. Applying it during peak plant growth yields better results, while using it during dormancy or slow growth phases wastes its potential. Farmers must align application with crop cycles and soil conditions.

3.3 Incorrect Application Techniques

Improper methods, such as surface sprinkling without soil integration or mixing with chemical fertilizers, reduce nitrogen availability. For example, surface application prevents nitrogen from penetrating deeper soil layers, while combining it with chemicals may trigger adverse reactions.

4. Other Limitations of Fermented Peanut Cake

4.1 Unbalanced Nutrient Composition

While fermented peanut cake contains trace elements like phosphorus and potassium, their proportions are often inadequate to meet full plant nutritional requirements. Relying solely on it as a nitrogen source neglects other critical nutrients.

4.2 Limited Microbial Activity

Microbial conversion efficiency in fermented peanut cake is lower compared to other organic fertilizers (e.g., livestock manure, green manure). This restricts its ability to enhance soil fertility and improve structure.

4.3 Poor Environmental Adaptability

The effectiveness of fermented peanut cake varies with soil type, climate, and weather conditions. Temperature, humidity, and rainfall significantly impact its performance, requiring careful consideration of local contexts before use.

Although fermented peanut cake offers nutritional value, its low nitrogen content, unstable fertility, and improper application practices prevent it from being used directly as a nitrogen fertilizer. In practical agriculture, it should be combined with other organic fertilizers, adjusted according to crop needs and soil conditions, and applied scientifically to optimize results.
