3、Post

This fertiliser is designed to simultaneously provide fruit trees in orchards with both zinc and boron. The last application of AMINO ULTRA® BORZIN can be applied at the beginning of leaf fall (5–10% fallen leaves) combined with a 5% urea solution (25–50 kg/ha urea in 500–1000 L of water).

4、Zinc Liquid Fertilizer: When and How to Apply for Maximum Plant Health

Zinc deficiencies can lead to stunted growth and poor yields, which is why implementing a reliable zinc liquid fertilizer is essential. Fervita liquid fertilizer, known for its effective nutrient delivery, incorporates zinc to enhance plant vitality.

Zinc Plus

Apply 10 kg of Zinc plus per acre at the time of basal application and 10 kg to 15 kg of Zinc plus per acre at the time of top dressing application. For horticulture crops, it is recommended to give 100 to 500 gm per crop (depending on crop size) at the time of flowering and fruit setting.

When to Apply Zinc Fertilizer for Fruit Trees

Proper application of zinc fertilizer can effectively support tree growth and development, boosting yield and fruit quality. Below are guidelines on usage, dosage, timing, and precautions for applying zinc fertilizer to fruit trees:

What is the recommended dilution ratio of water soluble zinc fertilizer

For fruit trees, a good starting point for the dilution ratio of our water - soluble zinc fertilizer is about 1 - 2 grams per liter of water. This can be applied through foliar spraying or soil drenching.

Activ Zinc

Activ Zinc-Manganese Orchards provides a full dose of zinc and manganese. Activ Zinc-Manganese Orchards provides complete solubility. The preparation is designed for application in orchard plantations: apple, cherry, gean, pear, plum, blueberry, raspberry and strawberry.

Zinc (Zn) for Plants: A Comprehensive Guide

In this guide, we will delve into the importance of zinc for plants, the symptoms of zinc deficiency, the causes of its deficiency, and the best ways to supplement it in soils.

Zinc Fact Sheet: Zinc Fertilizer Overview

Fertigation is a relatively new application method in which both Zn fertilizers and NPK fertilizers are added together to irrigation water to improve uniform distribution, homogeneous mixing, greater availability and reduced risk of damage to plants, especially in semi arid and arid areas.

Fertilizing orchards is a critical practice for enhancing fruit quality, increasing yield, and improving soil structure. Zinc fertilizer, as a micronutrient supplement, plays a vital role in the growth and development of fruit trees. When applying zinc fertilizer in orchards, it is essential to determine the appropriate dosage based on factors such as soil conditions, tree species, growth stages, and the form of zinc fertilizer (e.g., zinc sulfate, zinc oxide). Below are recommendations for zinc application rates per mu (approx. 0.067 hectares) in orchards:

I. Assess Soil Conditions

1. Soil Testing: Conduct soil analysis to measure zinc content and its availability. This helps determine whether zinc supplementation is needed, as well as the type and amount of zinc fertilizer.
2. Soil pH: Soil acidity or alkalinity affects zinc solubility and crop absorption. In acidic soils, zinc is more readily absorbed, allowing for higher application rates.
3. Soil Texture: Soil particle size influences zinc mobility and uptake. Sandy soils may leach zinc, while clayey soils retain zinc but release it slowly. Adjust application rates accordingly.

II. Consider Tree Species and Growth Stages

1. Tree Species: Different fruit trees have varying zinc requirements. For example, apple and pear trees require more zinc, while peach and apricot trees need less.
2. Growth Stages: Zinc needs change across developmental phases. Seedlings require higher zinc levels, while mature fruiting trees need less. Reduce zinc during late fruit ripening.

III. Choose the Right Zinc Fertilizer Form

1. Zinc Sulfate: A common, cost-effective option. its absorption by plants is limited, so combine with other fertilizers.
2. Zinc Oxide: Highly active and quickly absorbed, but expensive and prone to volatilization. Use for specific needs.
3. Other Forms: Options like zinc chloride or zinc nitrate require attention to soil pH and plant absorption rates.

IV. Timing and Application Methods

1. Timing: Apply zinc early in the growth cycle when nutrient demand is high. Avoid excessive use later in the season.
2. Methods: Broadcast zinc around the root zone or bury it for most trees. For grapes, foliar spraying (dissolved in water) is effective.

V. Environmental Factors

1. Climate: In dry regions, increase zinc to counteract low soil moisture; in humid areas, reduce dosage to avoid waste.
2. Pest Control: Combine zinc with fungicides/pesticides to reduce disease risks. avoid overuse to prevent harm to trees.

VI. Safety and Eco-Friendliness

1. Personal Safety: Wear masks, gloves, and ensure application sites are away from flammable materials.
2. Environmental Protection: Prevent zinc runoff into waterways and dispose of unused fertilizer responsibly.

VII. Recommendations

1. Dosage: Apply 5–20 kg/mu of zinc, adjusted based on soil tests, tree type, growth stage, and fertilizer form.
2. Application Principles:
   • For zinc sulfate, monitor soil pH and plant response. Adjust rates or switch forms if needed.
   • Follow "small doses, multiple applications" to minimize waste and negative effects.
   • Monitor tree health and soil zinc levels regularly. Recalibrate dosage if issues arise (e.g., yellowing leaves).
3. Integrated Fertilization: Combine zinc with nitrogen, phosphorus, and other nutrients to boost efficiency.
4. Expert Consultation: Seek advice from agricultural professionals before finalizing fertilization plans.

The ideal zinc application rate per mu depends on soil, tree species, growth stages, fertilizer type, and environmental conditions. By tailoring practices to these factors, orchards can achieve better fruit quality, higher yields, and improved soil health.
