1、Foliar nutrition: Potential and challenges under multifaceted

The potential of foliar fertilization in improving crop yield and quality under environmental stresses has been evaluated based on a meta-analysis. Foliar-applied fertilizers showed higher crop plants yield and quality traits by 15–19% and 9–29%, respectively, under different environmental stresses.

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 fertilizers: Enhancing nutrient uptake for healthy plants

Among the arsenal of agricultural practices, foliar fertilization has emerged as a powerful tool to provide plants with essential nutrients directly through their leaves.

4、Guide to Foliar Fertilization: Best Practices, Dosages, and Benefits

In modern agriculture, foliar fertilization has emerged as a vital technique for enhancing nutrient uptake, especially under conditions where root absorption is compromised.

Fertilizing Your Garden in Fall: A Comprehensive Guide

Fall fertilization ensures that soil nutrients are readily available during the spring bloom. The process of nutrient breakdown can take time, and adding fertilizers in fall enhances soil nutrient concentration, which aids plants during their prime growing season when they awaken from dormancy.

What Fertilizer is Best for Fall?

This article explores why fall is such an important season for fertilizing, the best types of fertilizers to use, the specific nutrients that plants need during this time, and the logistical advantages of fall fertilization.

Foliar Fertilization: Novel Approaches and Field Practices

When nutrient uptake from the soil is inhibited, foliar fertilization can be an alternative and highly effective way to supply plants with the missing macronutrients and micronutrients, so its use to compensate for nutrient deficiencies is an integral procedure in agricultural production.

Is Foliar Fertilization of Rice Beneficial During the Beginning of Autumn?

Foliar fertilization, an efficient method of nutrient delivery, directly supplies nutrients to plant leaves, promoting growth and enhancing yields. Applying foliar fertilizer during the beginning of autumn offers the following advantages for rice:

Should You Fertilize Vegetables in Fall? Here’s What Gardeners Recommend

Why You Should Fertilize Fall Vegetables According to Amanda Staples, owner and farmer at Germantown Kitchen Garden in Philadelphia, fertilizing in late summer can actually help vegetable crops.

Foliar fertilization is a critical nutritional supplementation method during autumn crop planting. It rapidly provides essential nutrients to plants, promotes growth, and enhances yield. Below are the reasons and detailed explanations for the necessity of using foliar fertilizers in autumn:

1. Importance of Foliar Fertilization in Autumn

Autumn is a crucial growth period for many crops. As temperatures decline and daylight shortens, soil moisture and nutrients deplete quickly. Timely nutrient replenishment is vital for crop development. Foliar fertilization directly delivers nutrients to leaves and stems, compensating for weakened root absorption and ensuring adequate nutrient supply.

2. Mechanism of Foliar Fertilizers

Foliar fertilizers typically contain essential nutrients like nitrogen (N), phosphorus (P), and potassium (K). These elements are critical for growth, photosynthesis, protein synthesis, and stress resistance. By spraying foliar fertilizers, nutrients are absorbed directly through leaves, accelerating growth, improving crop quality, and boosting yields.

3. Application Methods for Foliar Fertilizers

Methods include spraying, drip irrigation, and soaking. The choice depends on crop type and fertilizer properties. Before application, conduct soil tests to assess nutrient levels and crop needs. Follow the principle of "small doses, frequent applications" to avoid over-fertilization, nutrient loss, or leaf burn.

4. Selection Criteria for Foliar Fertilizers

Consider the following when choosing foliar fertilizers:

• (1) Composition: Select composite fertilizers rich in N, P, and K to meet crop nutritional demands at different stages.
• (2) Properties: Choose water-soluble, non-caking, and stable formulas for optimal effectiveness.
• (3) Compatibility: Match fertilizer types to crop species and local soil conditions.

5. Optimal Timing for Application

Apply foliar fertilizers during early growth stages or slow-growth periods. Key periods include post-germination, pre-flowering, and fruit expansion stages, which maximize growth promotion and yield potential.

6. Precautions for Foliar Fertilization

• (1) Avoid mixing with alkaline substances to prevent chemical reactions that reduce efficacy.
• (2) Do not apply during rainy days or extreme heat to avoid runoff or leaf damage.
• (3) Avoid over-application to prevent nutrient excess or soil salinization.

7. Economic Benefits of Foliar Fertilization

Despite higher costs, foliar fertilization offers rapid results and labor/resource savings. For large-scale agriculture, it significantly improves production efficiency, enabling sustainable resource use and long-term agricultural viability.

Foliar fertilization is essential during autumn planting because it quickly addresses nutrient gaps, promotes crop growth, and increases yields. proper application methods and precautions must be followed to ensure effectiveness.
