• High Bioavailability: Chelation with amino acids avoids calcium fixation in soil (e.g., with phosphate), ensuring efficient absorption by banana roots and leaves even in acidic or alkaline soils.

• Soil-Friendly: Reduces soil compaction, improves soil structure, and enhances soil microbial activity, contributing to sustainable cultivation.

• Synergistic Nutrition: Amino acids in the formula promote the absorption of other nutrients (e.g., potassium, magnesium), optimizing overall nutrient utilization.

• Environmental Safety: Complies with organic agricultural standards, free of harmful residues, suitable for green and export-oriented banana production.

Amino acid chelated calcium is a high-efficiency, bioavailable nutrient supplement tailored for banana cultivation, addressing key challenges in banana growth and significantly enhancing yield and fruit quality.

Core Application Scenarios & Efficacy

1. Seedling Stage (30-60 Days After Transplanting)Dilute 800-1000 times and apply via foliar spray or root irrigation. The chelated form ensures rapid absorption, strengthening root systems and stem toughness, reducing seedling blight and transplant shock. It promotes uniform seedling growth, laying a solid foundation for subsequent fruiting.

2. Vegetative Growth Stage (60-120 Days)Apply 1-2 times monthly with a dilution ratio of 1000-1200 times (foliar spray or drip irrigation). It boosts leaf photosynthesis efficiency, increases chlorophyll content, and enhances nutrient accumulation. Effectively prevents leaf yellowing, tip burn, and premature defoliation caused by calcium deficiency, supporting robust pseudostem development.

3. Flowering & Fruit Setting StageSpray once every 7-10 days for 2-3 consecutive applications (dilute 1200 times). It improves pollen viability and pollination rate, reducing flower and fruit drop. Enhances fruit setting rate by 15%-20% and promotes uniform fruit formation, minimizing misshapen fruits.

4. Fruit Expansion & Ripening StageApply via drip irrigation (dilute 1500 times) or foliar spray (dilute 1200 times) once every 10-15 days. It accelerates fruit cell expansion, increases fruit weight (single fruit weight improved by 10%-15%), and enhances fruit firmness. Significantly reduces physiological disorders such as blossom end rot, cracking, and sunscald—key issues in banana cultivation—by 30%-40%. Improves fruit sugar content, flavor, and storage stability, extending shelf life by 5-7 days.

DOLE Banana Growing and taking care Special Fertilizer

10% Calcium Chelated is the two divalent cations, it is very useful in maintaining plant branch and stem strength. At the same time it can regulate the absorption of nutrients through the plasma membrane. Calcium can also affect cell growth and division, and the permeability of the cell membrane structure, nitrogen metabolism and hydrocarbons conversion. Although the concentration of calcium in plants and nitrogen, potassium concentration is high, but many agronomists think that it is a minor, or micro nutrients. Even a high concentration of calcium is also non-toxic and can be used as an antidote to clean harmful components and maintain the balance of yin and Yang ion cavitation due to calcium. Is a component of the cell wall, and as a gelling agent can make the cell wall more firmly, so it is one of the important factors affecting the degree of firmness and storage period of the fruit. In addition, the concentration of calcium in the seed also directly affect its survival. 

2.   Main Function:

2.1  To strengthen the plant cell membrane to make the the fruit far from the harm of pests and diseases and promote a good harvest

2.2  To promote growth of root,and the effective carbohydrate metabolism.

2.3  To eliminate the toxic effects from other positive ions , such as hydrogen ions(H+), ammonium ions(NH4+), aluminum ions(Al3+ ) ,magnesium ions(Mg2+) and so on.This effects is called ion antagonism.

3.  Scope:

To all the fruit ,banana,  pineapples, kiwifruits, mango, vegetable and other economic crops ,such as apple, tomato,cotton and so on.

Usage

4.1  proposed dosage as the foliar spray fertilizer on the plants .

You also can have a flexible usage according to the crop varieties, growing season, the weather rain or shine, wet and dry soil, flexible use of basal conditions and other factors.

4.2  You can mix it with pesticides,which will enhance the function with each other

4.3  Please spray it before 10am or after 4pm so that the plant will have the best absorption.
