1、The Best Water

Water-soluble fertilizers, a critical component of modern agricultural practices, play a vital role in enhancing peanut productivity and quality. Below is a detailed analysis of the optimal water-soluble fertilizers to use during the late growth stage of peanuts.

2、Growing Peanuts – Fertilizers for Peanuts

Peanuts grow best in a soil pH range of 6.0-7.5, with liming recommended for pH levels below 6.0 to enhance fertilizer efficiency. Well-drained, light-colored, loose, friable sandy loams with high levels of calcium (Ca) and moderate organic matter are ideal for peanut cultivation.

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

Our findings can help optimize phosphate fertilizer use in tropical sandy soils with low fertility by lowering the current P fertilization recommendation and using peanut cultivars that are more efficient in P acquisition and tolerant to variable water availability.

4、Fertility Considerations for Peanut Plants

Polysulfate is a multi-nutrient fertilizer providing calcium, sulfur, magnesium, and potassium. For peanut production, calcium is particularly important for pod development.

5、What is the Best Fertilizer for Peanuts? Maximize Your Yields

This article provides peanut fertilizer recommendations and explains how to maximize your yields by understanding peanut nutrient requirements and implementing effective peanut nutrient management.

Effect of N, P K, Ca and Mg Fertilizer Application on Peanuts in Tra

In Jinzhou, Fujian and other places, experiments applying calcium, magnesium and sulfur containing fertilizers to peanut have shown that peanut yield has increased significantly (Huang et al., 2012).

Peanut Fertilization, University of Florida

Calcium and magnesium (Mg) may be supplied by limestone. If no lime is needed, Ca can be supplied by gypsum, and Mg can be included in the fertilizer. If phosphorus (P) is low, add P according to soil tests. The same is true for potassium (K) and other nutrients needed by peanuts.

Peanuts Crop Recommendation

All of these can be applied as pre-plant (liming) or foliar (minor elements). In case of big deficiencies, those elements can be fertigated (mainly Ca, Mg, and S).

Peanuts, as an important oil crop, have critical nutritional requirements during their growth. Microelements such as calcium, iron, magnesium, zinc, boron, and potassium play indispensable roles in peanut development and yield. Water-soluble fertilizers are favored by agricultural producers due to their high absorption efficiency. Below is a detailed analysis of whether peanuts can use water-soluble fertilizers containing these elements and the benefits they offer.

1. Calcium

• Function: Calcium is essential for plant health. In peanuts, it enhances disease resistance, improves fruit quality, and promotes root development. Early application of calcium fertilizers can prevent physiological diseases like root rot and leaf spot caused by calcium deficiency. Calcium also boosts flowering, fruiting, and overall yield.
• Recommendation: Use calcium fertilizers with good water solubility. Apply 5–10 kg per mu (approx. 0.06–0.13 hectares) in split applications to maintain consistent soil calcium levels.

2. Iron

• Function: Iron is critical for chlorophyll synthesis and photosynthesis. Iron deficiency leads to stunted growth or death. Early iron fertilization prevents chlorosis, ensuring normal photosynthesis.
• Recommendation: Choose iron fertilizers with good water solubility. Apply 3–5 kg per mu in split doses to optimize absorption.

3. Magnesium

• Function: Magnesium acts as an enzyme activator, supporting growth and soil microbial activity. It aids in protein synthesis, directly impacting peanut quality.
• Recommendation: Use magnesium fertilizers with high solubility. Apply 1–2 kg per mu in split applications to sustain soil magnesium levels.

4. Zinc

• Function: Zinc is a component of multiple enzymes, promoting root growth, pest resistance, and pollen formation/dispersal.
• Recommendation: Select zinc fertilizers with good water solubility. Apply 3–5 kg per mu in split doses to maintain soil zinc availability.

5. Boron

• Function: Boron supports metabolic processes, flower bud differentiation, fruit setting, and root system development. It also enhances water and nutrient uptake.
• Recommendation: Use boron fertilizers with high solubility. Apply 1–2 kg per mu in split applications to ensure continuous boron supply.

6. Potassium

• Function: As a key cation, potassium strengthens roots, improves water/nutrient absorption, and aids protein synthesis.
• Recommendation: Choose potassium fertilizers with good solubility. Apply 10–15 kg per mu in split doses to stabilize soil potassium levels.

7. Comprehensive Fertilization Strategies

• Rational Combination: Tailor water-soluble fertilizers to growth stages and soil conditions. For example, apply nitrogen-rich fertilizers early to promote growth, then shift to phosphorus-potassium-rich formulas during flowering/fruiting.
• Scientific Application: Determine dosages based on soil fertility, climate, and plant status. Avoid over-fertilization by following the "small amounts, multiple times" principle.
• Organic-Inorganic Synergy: Combine organic fertilizers (rich in microelements and organic matter) with chemical fertilizers to enhance soil structure and fertility while meeting nutrient demands.

Peanuts can effectively use water-soluble fertilizers containing calcium, iron, magnesium, zinc, boron, and potassium. These elements are vital for growth and yield. avoid excessive application to prevent resource waste and soil degradation. Integrting organic and synthetic fertilizers yields optimal results.
