1、Guide to Fertilizing Your Peanut Plant

Based on the results of your soil test, you can calculate the appropriate amount of fertilizer needed to meet your peanut plant’s requirements. Generally, a balanced fertilizer with an N-P-K ratio of 10-10-10 or 14-14-14 is suitable for peanuts.

2、Optimizing phosphorus rates for peanut: The role of soil P, water

Despite peanuts’ ability to acquire P from low-fertility soils, current fertilizer recommendations are based mainly on labile soil P content and expected yield, with little consideration for cultivar-specific traits or environmental constraints such as water availability.

3、How to fertilize peanut planting? What kind of fertilizer should I use

Planting peanuts with any fertilizer is not as good as using mature farm manure before planting peanuts, so that the base fertilizer is exuberant, the fertilizer used for peanuts is reduced in the later stage, and the organic nature of peanuts is guaranteed.

4、The UGA Peanut Fertilization Strategy … In a Nutshell

Because the peanut plant is a deep-rooted legume that fixes nitrogen and is a good scavenger of “P&K’, most people say it doesn’t need a lot of fertilizer.

Peanut Fertilization Program

Soil phosphorus content is an important factor determining peanut yield levels, and phosphorus fertilizer should not be applied late. The fertilization principle for peanuts is to halve nitrogen fertilizer, double phosphorus fertilizer, and apply all potassium fertilizer, N:P2O5:K2O = 1:0.8:1。

What Kind Of Fertilizer For Peanuts

Peanuts, being part of the legume family, naturally fix their own nitrogen, so it's essential to choose fertilizers with lower nitrogen content, such as a 5-10-10 fertilizer.

What Type Of Fertilizer Is Best For Peanuts?

Peanuts respond best to residual fertilization that has been applied to the crop preceding peanuts; however, if the area to be planted has not been fertilized during the prior 12 months, then ahead of planting, apply 10 pounds 0-10-20 fertilizer per 1,000 square feet.

Granular fertilizers are popular for their ease of use; just ensure you follow the recommended application rates and distribute them evenly across the soil. For liquid fertilizers, dilution ratios matter.

The amount of phosphate fertilizer required for planting peanuts depends on multiple factors, including soil type, peanut variety, planting density, and fertilization timing. When determining the fertilization rate, these factors must be considered to ensure peanuts receive adequate phosphorus nutrition. Below is a detailed guide to help you calculate the required phosphate fertilizer amount.

1. Determine Soil Type

Understanding your soil type is critical for selecting the appropriate phosphate fertilizer amount. Soils can be categorized as acidic, neutral, alkaline, or calcareous, each with distinct phosphorus content and availability.

• Acidic Soil: These soils typically have higher organic matter but lower phosphorus levels. More phosphate fertilizer may be needed to meet peanut requirements.
• Alkaline Soil: High pH levels in these soils can reduce phosphorus availability. Phosphate or calcium-based phosphate fertilizers (e.g., superphosphate) may be used to improve phosphorus uptake.
• Neutral Soil: With moderate pH, neutral soils generally do not require additional phosphorus. balanced nutrient application (including phosphorus) is recommended.
• Calcareous Soil: High pH in these soils often reduces phosphorus effectiveness. Phosphate supplements (e.g., soluble phosphate fertilizers) may be necessary.

2. Analyze Soil Test Results

If available, conduct a soil test to guide fertilization. Soil tests provide data on phosphorus levels, pH, and other key nutrients (e.g., nitrogen, potassium, sulfur). Use this information to calculate precise phosphate requirements.

3. Identify Peanut Variety and Planting Density

Different peanut varieties have varying phosphorus demands. High-yield or early-maturing varieties often require more phosphorus. Planting density also impacts phosphorus needs: denser plantings increase competition among plants, potentially reducing phosphorus absorption. Adjust fertilization based on your specific variety and density.

4. Timing of Fertilization

Fertilization timing affects phosphate effectiveness. Spring is typically critical for peanut growth, but optimal timing varies by region and climate. Align fertilization with local growing seasons and crop development stages.

5. Calculate Required Phosphate Fertilizer

Use the following formula to estimate phosphate needs:

[ ext{Required Phosphate} = ( ext{Soil Test Value} + ext{Varietal Requirement}) imes ext{Planting Density Coefficient} ]

• Soil Test Value: Obtained from soil analysis.
• Varietal Requirement: Specified for your peanut variety (consult agricultural guidelines).
• Planting Density Coefficient: Reciprocal of plants per unit area (e.g., for 6,000 plants/mu, use ( frac{1}{6000} )).

6. Choose the Right Phosphate Fertilizer

Select phosphate sources and forms based on:

• Phosphorus Source: Common options include ammonium phosphate (e.g., monoammonium phosphate, diammonium phosphate) or calcium-based phosphate fertilizers. Match the source to soil conditions.
• Form: Choose between granular, powdered, or liquid formulations based on application method and soil type.

7. Fertilization Methods

Apply phosphate fertilizers via:

• Base Fertilization: Incorporate into soil before planting.
• Topdressing: Apply during growth stages (e.g., flowering).
• Foliar Spraying: Use diluted solutions for direct absorption by leaves.

8. Key Considerations

• Avoid Over-Fertilization: Excess phosphorus can stunt growth or reduce yields. Follow recommendations strictly.
• Separate from Nitrogen: Mixing phosphorus and nitrogen fertilizers may disrupt nutrient balance. Apply separately.
• Monitor Soil and Crop Health: Regularly test soil and observe plants to adjust fertilization strategies.

By integrating these factors and adhering to best practices, you can optimize phosphorus supply for healthy peanut growth and maximize productivity.
