1、Foliar Fertilization for Sustainable Crop Production

Here I review the extensive work that has been carried out on the effectiveness of foliar-applied nutrients, the mechanisms of foliar absorption, and transport.

2、Use of Foliar Fertilizers for the Specific Physiological Management of Different Soybean Crop Stages

Based on the assumption that foliar fertilizers applied at specific times promote soybean growth, development and yield, the aim of the present study was to evaluate the biometric, biomass, physiological, nutritional and grain yield parameters to increase knowledge about specific fertilizers applied alone or in combination and at different ...

3、Absorption of foliar

To further quantify the overall importance of trichomes in foliar Zn absorption, we compared the absorption of foliar-applied Zn in four soybean NILs that differed up to 10-fold in their trichome density (Fig. 6).

Nano

The main objectives of this study were to combine the Pheroid technology with FeSO 4 or nanostructured FePO 4 to develop a novel foliar Fe fertilizer, and to test it for enhancement of seed Fe concentrations in soybeans compared with commonly used foliar fertilizers like FeSO 4 and FeSO 4 with citrate.

EFFECT OF FOLIAR FERTILIZATION ON SOYBEAN GRAIN YIELD

The aim of this investigation was to the effects of soil and foliar fertilization on agronomic traits and grain yield in two soybean cultivars and to determine better foliar fertilizer and genotype in agro-climatic condition of Srem.

Effect of N fertilizer and foliar

Therefore, the objective of this field experiment was to study the effect of N fertilizer applied to the soil at R4 and foliar spray, and the Fe fertilizer effects at the R1 and R3 stages on soybean grain yield and the quality.

Foliar application of organic and inorganic iron formulation induces differential detoxification response to improve growth and biofortification in soybean

Foliar fertilization for biofortification is a targeted, economic and environment friendly approach rather than soil fertilization. In this study, we identified the appropriate growth stage (s) and right foliar iron (Fe) formulation in enhancing growth and Fe biofortification in soybean.

Interplay between nitrogen fertilizer and biological nitrogen fixation in soybean: implications on seed yield and biomass allocation

The goal of this study was to investigate the effect of fertilizer N application on BNF and its implications for soybean seed yield and seed protein concentration.

Effect of Foliar Nitrogen and Basal Phosphorus Fertilization on Growth and Nutrient Uptake of Soybean in Vertisols of the Mewar Region

Based on the findings, it is recommended that foliar fertilization with 2.5% urea along with 100% basal phosphorus should be adopted for enhancing soybean productivity and nutrient use efficiency ...

Sucrose fatty acid esters enhance efficiency of foliar

A greenhouse study is described showing the effect of sucrose fatty acid esters (SFE) applied to soybeans (Glycine max (L.) Merrill cv Fukuyutaka) during the flowering and/or pod-filling periods on the efficiency of foliar-applied urea-nitrogen.

Soybean (Glycine max), also known as soybean, is a vital food and oil crop that plays a significant role in global agricultural production. To ensure healthy growth, yield, and quality of soybeans, rational fertilization is critical. Foliar fertilizers, applied directly to plant leaves, are rapidly absorbed and utilized by plants, playing a key role in promoting soybean growth. Below are recommended types of foliar fertilizers and their application methods to optimize soybean development.

1. Nitrogen Fertilizers

1. Function: Nitrogen is a primary nutrient for plant growth, especially for leguminous crops like soybeans. It promotes the growth of stems, leaves, and pods, increases protein content, and improves pod quality.

2. Recommended Products: Urea, ammonium nitrate, and ammonium sulfate are suitable nitrogen sources. These can be directly sprayed onto soybean plants and converted into nutrients via leaf absorption.

3. Application Method: Select appropriate nitrogen fertilizers and concentrations based on soybean growth stages. Apply nitrogen before flowering to enhance growth and flower bud differentiation, and focus on pod formation and seed filling after flowering.

2. Phosphate Fertilizers

1. Function: Phosphate fertilizers promote root development, enhance disease resistance, and improve seed plumpness and yield.

2. Recommended Products: Superphosphate, potassium dihydrogen phosphate, etc.

3. Application Method: Best applied around the flowering stage. Phosphate fertilizers can be mixed with nitrogen fertilizers or applied separately via foliar spraying.

3. Potassium Fertilizers

1. Function: Potassium improves drought and lodging resistance, accelerates fruit maturation, and enhances seed plumpness.

2. Recommended Products: Potassium chloride, potassium sulfate, etc.

3. Application Method: Apply around flowering, but avoid overuse to prevent growth abnormalities.

4. Microelement Fertilizers

1. Function: Microelements like iron, zinc, copper, and manganese regulate enzyme activity, boost stress resistance, and promote reproductive growth.

2. Recommended Products: Chelated microelement fertilizers (e.g., chelated iron, chelated zinc).

3. Application Method: Apply early in soybean growth and separately from major fertilizers to avoid interactions.

5. Water-Soluble Fertilizers

1. Function: These fertilizers contain essential macro- and micronutrients, are highly soluble, and easily absorbed by plants.

2. Recommended Products: Liquid compound fertilizers, water-soluble NPK blends, etc.

3. Application Method: Dilute according to instructions and spray directly on plants. Can also be used as base fertilizer.

6. Key Considerations

1. Fertilization Rate: Adjust based on growth stage, soil conditions, and climate to avoid waste or leaf burn.

2. Timing: Apply in morning or evening to reduce evaporation and volatilization.

3. Method: Use efficient techniques like drip or sprinkler irrigation to maximize absorption and minimize environmental impact.

4. Soil Testing: Conduct pre-fertilization soil tests to assess nutrient levels and pH.

5. Pest Control: Integrate fertilization with pest/disease management for holistic plant health.

scientific selection and application of foliar fertilizers provide essential nutrients for soybeans, supporting healthy growth and high-quality yields. Monitor plant responses during fertilization and adjust strategies to optimize growing conditions.
