1、Foliar Application of Sulfur

The challenges associated with the penetration of the applied mineral nutrients during foliar have prompted the extensive utilization of adjuvants and ongoing research to discover new ones that can improve the effectiveness of spray treatments.

2、Effects of Foliar Fertilization: a Review of Current Status and Future

Foliar fertilizer application after soil fertilization is an effective method to increase the contents of trace elements in crops and crop yield, and to improve the soil environment. However, the application of inorganic foliar fertilizer results in difficulties in nutrient absorption and migration in plants.

3、Foliar nutrition: Potential and challenges under multifaceted

Foliar fertilization has been well recognized for two decades to affect crop productivity, however, the consequences of foliar spray under multiple environmental stresses remains elusive, albeit evidence to resilience agriculture has grown widely.

4、Foliar Application of Ca

This study evaluated the effects of foliar-applied calcium-based fertilizers, including a conventional fertilizer (T1) and a nanofertilizer containing Ca, Si, B, and Fe (T2), on fruit traits, seed quality, and early seedling growth of seven determinate tomato genotypes.

Effects of Foliar Fertilization: a Review of Current Status and Future

Foliar fertilizer application after soil fertilization is an effective method to increase the contents of trace elements in crops and crop yield, and to improve the soil environment. However, the application of inorganic foliar fertilizer results in difficulties in nutrient absorption and migration in plants.

Foliar Fertilization

Ideally foliar feeds should be applied in the cooler morning or evening hours. It is not advisable to spray leaves during the heat of the day. The combined effects of fertilizer and sunlight on the foliage could cause tissue damage.

Foliar Fertilization: Scientific Principles and Field Pratices

Foliar fertilization offers a specific advantage over soil fertilization when plant demand for nutrients exceeds the capacity of the roots to absorb nutrient and when environmental...

Recent Trends in Foliar Nanofertilizers: A Review

As can be seen from publications in recent years, the foliar application of nanofertilizers has attracted widespread attention and can be applied alone or as a supplement to soil fertilization.

Recent Trends in Foliar Nanofertilizers: A Review

It can be seen that nanofertilizers and foliar fertilization are the hotspots of attention at present and that current research on the foliar application of nanofertilizers is not as extensive as that on soil application.

Foliar

Numerous nanoformulations have recently developed to strengthen foliar application’s efficacy by overcoming many inherent challenges like precise targeting of active compounds to specific plant tissues, improved penetration, and controlled release and reduced environmental impact.

Tissue culture seedlings, also known as in vitro propagated plants or soilless culture seedlings, refer to plantlets grown under sterile conditions using plant tissue culture techniques (e.g., shoot tip culture, root tip culture). These seedlings are commonly used in scientific research, commercial production, or ornamental purposes due to their rapid growth, strong reproductive capacity, and independence from seasonal or climatic constraints.

I. Feasibility of Applying Foliar Fertilizer to Tissue Culture Seedlings

1. Nutritional Requirements: As artificially cultivated plants, tissue culture seedlings have distinct nutritional needs compared to naturally grown plants. During cultivation, deficiencies in certain nutrients may limit growth. Appropriate foliar fertilization can supplement missing micronutrients and macronutrients.

2. Environmental Adaptation: Tissue culture seedlings often require specific environmental conditions (e.g., high light intensity, optimal temperature ranges) for healthy development. Foliar fertilizers can help provide essential nutrients tailored to these conditions.

3. Growth Stages: Nutrient demands vary across growth phases. For example, young seedlings may require higher nitrogen levels to promote leaf development, while mature stages benefit from phosphorus and potassium to support root formation. Foliar fertilizers can be customized to match these阶段性needs.

4. Pest and Disease Control: Certain foliar fertilizers contain natural antimicrobial components that enhance plant immunity, reducing the risk of pests and diseases.

II. Potential Impacts of Foliar Fertilizer on Tissue Culture Seedlings

1. Concentration Effects: The efficacy of foliar fertilizers depends critically on concentration. Excessive concentrations may damage seedlings, while diluted solutions might fail to deliver adequate nutrients. Proper formulation based on specific requirements is essential.

2. Chemical Composition: The ingredients of foliar fertilizers significantly affect growth. Hormones or growth regulators in some formulas can accelerate development but may cause abnormalities (e.g., stunted growth) if overused.

3. Environmental Risks: Improper use of foliar fertilizers may lead to pollution. Heavy metals or toxic substances in fertilizers could leach into soil or water systems. Eco-friendly products and soil-avoidance application are recommended.

4. Biosafety Concerns: As artificially cultivated plants, tissue culture seedlings may absorb harmful chemicals from fertilizers, posing risks to human health if consumed. Ensure fertilizers meet safety standards to avoid bioaccumulation.

III. Recommendations

1. Select Appropriate Fertilizers: Choose certified, eco-friendly foliar fertilizers aligned with the seedlings’ growth stage, nutritional gaps, and environmental conditions.

2. Precision Application: Apply fertilizers based on real-time growth data and soil conditions. Avoid over-application or direct soil contact to prevent contamination.

3. Monitoring and Adjustment: Regularly assess seedling health, nutrient uptake, and fertilizer effects. Adjust formulations dynamically for optimal results.

4. Integrated Management: Combine foliar fertilization with other practices, such as controlled irrigation, balanced root-zone fertilization, and pruning, to ensure holistic care.

applying foliar fertilizer to tissue culture seedlings is a viable strategy but requires careful consideration of feasibility, dosage, environmental impact, and biosafety. Scientifically guided practices will maximize benefits while minimizing risks, ensuring healthy seedling development.
