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、Foliar Fertilization of Crop Plants: Journal of Plant Nutrition: Vol 32 , No 6

Soil applications of fertilizers are mainly done on the basis of soil tests, whereas foliar nutrient applications are mainly done on the basis of visual foliar symptoms or plant tissue tests. Hence, correct diagnosis of nutrient deficiency is fundamental for successful foliar fertilization.

3、Foliar application of zinc sulphate and zinc EDTA to wheat leaves: differences in mobility, distribution, and speciation

The results of the present study provide important insights into the behaviour of commonly used foliar-applied Zn fertilizers, and can be used to optimize current fertilization strategies and contribute to the development of more efficient foliar Zn fertilizers.

Copper

These results clearly indicate that the application of copper-based foliar fertilizer with added zinc and controlled release urea is favorable for tomato.

Nanotechnology promotes the R&D of new

The new screening criteria of new-generation micronutrient foliar fertilizers have been put forward from the viewpoints of material engineers, and our recent research efforts using nanotechnology to design and develop new foliar fertilizers have been summarised.

Growth and quality of cucumber, tomato, and green bean under foliar and soil applications of an aminochelate fertilizer

Nevertheless, the results indicate that the application of aminochelate especially foliar application, is a preferred method for fertilization under lime soil conditions to improve plant growth, productivity, and quality.

Understanding and Applying Chelated Fertilizers E ec tively Based on Soil pH 1

micronutrient chelates and soil can be avoided by using a foliar application. Chelated nutrients also facilitate nutrient uptake eficiency for foliar application because crop leaves are naturally

RESPONSE OF MAIZE TO FOLIAR VS. SOIL APPLICATION OF NITROGEN–PHOSPHORUS–POTASSIUM FERTILIZERS: Journal of Plant Nutrition: Vol 25 , No 11

Three forms of foliar fertilization were applied once a week in equivalent concentrations of N, P, and K (0.12 g N, 0.08 g P, and 0.06 g K/L): Mineral forms (NPK), GG, and “Fertilizers & Chemicals” (F&C) foliar fertilizers; plain water acted as the control. The plants were harvested after 55 days.

Influence of potassium fertilization and foliar application of zinc and phosphorus on growth, yield components, yield and fiber properties of Egyptian

The factors studied were K fertilization, foliar application of Zn and P fertilizers. The experiment was arranged according to randomized complete block (RCB) design with four replications. The soil in both seasons was clay loam.

Effect of foliar application of NPK nanoparticle fertilization on yield and genotoxicity in wheat

In the present study, we examined the effects of a Hyper Feed Amino NPs (NPK NPs) fertilizer applied by foliar spraying on yield characteristics, mitotic indexes, and chromosomal aberrations in wheat during the green growth stage and after harvesting.

Foliar fertilizers are nutrients applied directly to the surface of plant leaves. They provide rapid nourishment, enhance crop growth rates, and increase yields. When selecting foliar fertilizers, factors such as primary ingredients, efficacy, suitable crops, application methods, and environmental impact should be considered. Below are common types of foliar fertilizers and their characteristics:

1. Microelement Foliar Fertilizers

   • Contain essential trace elements like iron, manganese, copper, and zinc, which are often deficient in soils.
   • Suitable for crops exhibiting obvious deficiency symptoms, such as rice, corn, and vegetables.
   • Application: Dilute the fertilizer and spray it onto plant leaves.

2. Compound Foliar Fertilizers

   • Composed of multiple nutrients (e.g., nitrogen, phosphorus, potassium) to meet diverse plant needs.
   • Ideal for crops requiring high levels of specific nutrients.
   • Application: Evenly spray the diluted solution onto leaves.

3. Water-Soluble Foliar Fertilizers

   • Dissolve easily in water for quick nutrient absorption.
   • Best for rapidly addressing nutrient deficiencies.
   • Application: Mix with water at recommended ratios and spray.

4. Biological Foliar Fertilizers

   • Contain live beneficial microorganisms that improve soil health and promote plant growth.
   • Suitable for crops in disease-prone or poor-soil conditions.
   • Application: Dilute and spray onto leaves.

5. Hormone-Based Foliar Fertilizers

   • Include plant growth regulators (e.g., gibberellins, cytokinins) to adjust growth cycles and stress resistance.
   • Used for crops requiring growth regulation, such as fruits and vegetables.
   • Application: Spray the diluted solution evenly on leaves.

Key Considerations for Selecting Foliar Fertilizers:

1. Crop Type: Choose fertilizers tailored to specific nutritional needs of the crop.
2. Nutrient Requirements: Match nutrient ratios to the crop’s growth stage.
3. Environmental Conditions: Account for local climate and soil properties.
4. Application Method: Follow guidelines for dilution ratios and spray timing.
5. Safety and Eco-Friendliness: Avoid products with heavy metals or harmful chemicals.
6. Cost-Effectiveness: Balance affordability with effectiveness.
7. Brand Reliability: Opt for reputable brands with proven quality.

the best foliar fertilizer depends on the crop’s unique needs and local conditions. Carefully evaluate all factors to choose the most suitable product.
