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.

Due to their variation in composition, the ecological fertilizers may induce different results in various species, thus evaluation for the optimal fertilizer, dose and period of application on a specific crop is needed.
4、COMPARISON OF DIFFERENT FOLIAR
Foliar fertilization is a rapid, efficient way to improve crop nutrient status during periods of high nutrient demand or when soil conditions (low tempera-ture, salinity, pH) render soil nutrients and soil-applied fertilizers less available to the plant’s roots.
5、Foliar Fertilization
Foliar fertilization has an increasing role in crop nutrition, but years of research and development work are still needed. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
RESPONSE OF MAIZE TO FOLIAR VS. SOIL APPLICATION OF NITROGEN–PHOSPHORUS–POTASSIUM FERTILIZERS
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 use of biovesicles to improve the efficiency of Zn foliar fertilization
Foliar fertilization is becoming very popular since it is highly efficient, minimizes contamination, and is target oriented. However, the low mobility of several nutrients and low penetration through the leaf cuticle should be addressed, to establish an efficient leaf applied fertilizer.
The Effect of Foliar Fertilization on the Yield and Quality of Different Crops
To avoid these complications, preventive foliar fertilization can be useful, specially for varieties with a high potential of yield and quality, and in climatically suboptimal years.
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.
Effect of foliar fertilization application on the growth and mineral nutrient content of maize seedlings under drought and salinity
Although there was a reduction in evapotranspiration, maize growth, such as shoot fresh weight and dry weight, and leaf fresh weight and dry weight under drought and salinity, the application of foliar fertilization did not improve plant growth under short-term drought or salt stress.
Foliar fertilization, also known as foliar spraying or leaf feeding, is a method of directly applying nutrient solutions to the surface of plant leaves. This approach rapidly replenishes essential nutrients for plants, enhancing crop growth rates and yields. the effectiveness of foliar fertilization is not immediate; it requires proper timing and frequency to achieve optimal results.
Understanding the Principles of Foliar Fertilization Foliar fertilization works by spraying nutrient solutions containing essential elements onto leaves, allowing these nutrients to enter the plant through stomata (pores on leaves). This process involves three critical stages: absorption, transport, and transformation. Absorption is the most crucial step, as nutrients must be taken up by the plant to fulfill their intended roles.
Determining Frequency and Timing The frequency of foliar fertilization depends on the plant’s growth stage, soil conditions, and the type of fertilizer used.
- Growth Stages: During early growth stages, plants demand more nutrients, so applications can be more frequent and concentrated. In later stages, reduced nutrient needs require fewer applications with lower concentrations.
- Fertilizer Types:
- Nitrogen fertilizers are best applied during vigorous growth phases.
- Phosphate fertilizers are ideal for flowering and fruiting periods.
- Potassium fertilizers can be used throughout the entire growth cycle.
Optimal Timing for Application Fertilizers are best applied in the morning or evening, when sunlight is weaker. This minimizes evaporation losses and aligns with peak plant metabolic activity. Avoid midday heat to prevent nutrient degradation.
Key Considerations for Effectiveness
- Environmental Factors:
- In dry conditions, increase application frequency and concentration due to low soil moisture.
- During rainy seasons, reduce applications to avoid nutrient runoff.
- Plant Health: Adjust fertilization if deficiency symptoms (e.g., yellowing leaves) appear. Tailor nutrient ratios to specific deficiencies.
- Observation: Monitor plant responses, such as improved leaf color, faster growth, or increased flowering. If issues persist, revise the application plan.
Foliar fertilization is a powerful tool for boosting agricultural productivity. To maximize its benefits, farmers must:
- Align application schedules with plant growth stages and environmental conditions.
- Choose appropriate fertilizers and concentrations.
- Adapt strategies based on real-time observations and weather patterns.
By mastering these practices, foliar fertilization can contribute to efficient, stable, and sustainable agricultural development.
