1、Foliar Fertilization: Novel Approaches and Field Practices

We compared three treatments: a control with soil application of ammonium sulfate (250 kg ha −1) and two endophyte foliar applications at different doses: a single high-dose application (M.SYM500 at 500 kg ha −1) and a split half-dose application (M.SYM250 at 250 kg ha −1 applied twice).

Making and applying foliar fertiliser and pesticide solutions

Getting the application of foliar fertilisers and pesticides right starts with making correct chemical solution mixtures of foliar fertilisers and pesticides. A series of steps are however needed to achieve this. The steps shall be described below using worked out examples.

Foliar fertilization is a method of applying fertilizers directly to the surface of plant leaves. It enhances nutrient uptake efficiency, reduces soil fertilizer runoff, and minimizes root damage. The proportion and application methods of foliar fertilizers are critical to plant growth and health. Below are recommendations for foliar fertilizer ratios and application techniques:

I. Fertilizer Proportions

1. Recommended Concentrations: For most plants, foliar fertilizer concentrations should be maintained between 0.2% and 1%. This range ensures effective nutrient absorption while avoiding damage to plants. Specific ratios depend on plant species, growth stages, and soil conditions.

2. Timing of Application: Apply foliar fertilizers in the morning or evening, when photosynthesis is active and nutrient absorption is optimal. Avoid midday applications, as strong transpiration may cause foliage burn.

3. Application Method: Spray fertilizers evenly across leaf surfaces. Use a sprayer or manual application to ensure full coverage without excess waste.

II. Application Methods

1. Spray Application: Use a sprayer to evenly distribute foliar fertilizer across leaves. Maintain proper distance and angle to prevent drift onto other plant parts.

2. Immersion Method: Submerge plant leaves in a foliar fertilizer solution for a short period, then air-dry. Suitable for salt-tolerant or drought-resistant plants, but requires precise control of solution concentration and soaking time.

3. Brush Application: Mix foliar fertilizer with water and apply it to leaves using a brush or soft cloth. Ideal for large plants, but avoid overapplication or excessive frequency.

III. Key Considerations

1. Select Appropriate Fertilizers: Choose foliar fertilizers tailored to specific plant needs. Opt for harmless, eco-friendly formulas to minimize environmental and human health risks.

2. Avoid Mixing with Pesticides: Combining foliar fertilizers with certain pesticides may trigger chemical reactions, reducing efficacy or causing adverse effects. Apply separately.

3. Monitor Plant Response: Observe plants closely after application. Adjust strategies if abnormal symptoms (e.g., leaf scorching) occur.

Foliar fertilization is an efficient and environmentally friendly practice when implemented correctly. By controlling fertilizer ratios, mastering application techniques, and adhering to precautions, plants can achieve healthier growth and improved yield/quality.
