The optimal fertilization strategy for enhancing soil nutrient distribution, WUE and NUE, and yield is proposed to be the application of 1100 kg/hm2 sesame cake fertilizer and 200 kg/hm2...

3、Integrated Effect of Filter Mud Cake Combined with Chemical and

The effect of filter mud cake (FMC) as an organic fertilizer and potassium sulfate as a chemical fertilizer (CF), either individually or combined with biofertilizers on potato growth and its yield as well as soil fertility, were evaluated.

4、Long

We hypothesized that long-term application of organic and inorganic fertilizers could improve grain yield sustainability and soil fertility in wheat–maize cropping systems.

Frontiers

It is commonly recognized that the use of cake fertilizer in medications, flicks, additives, etc. necessitates the extraction of compounds unique to the fertilizer, which is an expensive and difficult procedure to carry out (Jingura and Kamusoko, 2018).

Ecological Modulation of Soil Microbial Communities by

Fertilization plays a vital role in replenishing soil nutrients, shaping microbial community composition, and enhancing agricultural productivity. Castor bean cake (CBC) is a nitrogen- and carbon-rich by-product increasingly used as an organic amendment, yet its effects on soil microbiomes remain unclear. Here, we compared CBC with a compound chemical fertilizer (CF) and a manure-based organic ...

Compound fertilizer should be used in conjunction with organic

Combined application of compound fertilizer and organic fertilizer can improve fertilizer efficiency and nutrient utilization. The application of organic fertilizer not only improves the soil, activates the beneficial microorganisms in the soil, but also saves energy and reduces environmental pollution.

Filter Cake Utilization as Filler of 15

Fertilizer production and fertilization technology in Indonesia are still relatively lacking, especially for compound fertilizers that combine organic-inorganic materials.

“In conclusion, substituting chemical fertilisers with organic fertilizers improves the soil moisture and organic matter content, thereby enhancing the total uptake and translocation efficiency of nitrogen, phosphorus, and potassium.

Combined application of organic and inorganic fertilizers sustained

In summary, ORG-INO treatment significantly reduced the yield-scaled NH3 emissions, and the partial substitution of organic fertilizers for inorganic fertilizers should be recommended to promote environmental sustainability while ensuring food security.

Organic cake fertilizer and compound fertilizers are two distinct types of agricultural inputs, each serving unique roles in crop production. Whether they can be used together depends on several factors analyzed below:

I. Differences in Nutrient Composition

1. Cake Fertilizer: Cake fertilizer typically refers to organic matter derived from animal byproducts (e.g., oilseed cakes) or fermented manure. It is rich in organic matter, nitrogen (N), phosphorus (P), potassium (K), and trace elements, playing a critical role in improving soil structure and providing balanced nutrients.

2. Compound Fertilizers: These are synthetic fertilizers formulated to supply primary macronutrients—nitrogen (N), phosphorus (P), and potassium (K)—in specific ratios. They act quickly to address nutrient deficiencies and boost yields but may pose risks of overapplication.

3. Nutrient Comparison: Cake fertilizer offers a broad spectrum of nutrients but may lack certain microelements. Compound fertilizers provide balanced N-P-K ratios but require precise dosage to avoid excess salts or nutrient imbalances.

II. Soil and Crop Considerations

1. Soil Type:

   • Sandy soils benefit from compound fertilizers high in phosphorus to enhance fertility.
   • Clay soils often need potassium-rich compounds to improve water retention.

2. Crop Requirements:

   • Legumes and root vegetables require higher nitrogen.
   • Leafy greens demand more potassium for healthy growth.

3. Timing: Base fertilization (e.g., compound fertilizers) is ideal during early growth stages, while cake fertilizer can be applied gradually as a supplementary nutrient source.

III. Application Methods and Effects

1. Application Techniques:

   • Cake fertilizer: Applied via broadcasting, furrow filling, or composting.
   • Compound fertilizers: Suitable for drip irrigation, foliar spraying, or targeted root-zone application.

2. Dosage Control:

   • Compound fertilizers require strict adherence to recommended rates to prevent "fertilizer burn" or soil salinization.
   • Cake fertilizer dosage depends on soil organic matter content and crop demands.

3. Timing:

   • Cake fertilizer should be split into multiple applications to sustain nutrient release.
   • Compound fertilizers can be applied in one go during critical growth phases (e.g., seedling stage).

IV. Environmental Factors

1. Climate:

   • Drought conditions reduce compound fertilizer efficacy due to poor dissolution.
   • Excessive rain may leach nutrients from both fertilizer types.

2. Growth Cycles:

   • Long-season crops need periodic top-dressing; short-season crops require fewer applications.

3. Pest Management:

   • Balanced fertilization (e.g., combining organic and synthetic inputs) can optimize soil pH and health, reducing pest susceptibility.

V. Integrated Recommendations

1. Synergistic Use: Combine cake fertilizer (for organic matter and micronutrients) with compound fertilizers (for rapid N-P-K delivery) based on soil tests and crop needs.

2. Scientific Practices:

   • Follow "small doses, multiple applications" to minimize environmental impact.
   • Adjust timing: Use compound fertilizers pre-planting and cake fertilizer during the growing season.

3. Eco-Friendly Approaches: Prioritize organic-inorganic blends, reduce synthetic overreliance, and choose low-pollution fertilizers to protect ecosystems and human health.

While cake fertilizer and compound fertilizers complement each other, their joint use must align with soil conditions, crop requirements, and environmental context. A balanced approach maximizes agricultural productivity while safeguarding sustainability.
