Product Introduction

Product Overview

Amino Acid Chelated Ca-Zn-B is a highly efficient amino acid chelated secondary and micronutrient fertilizer. It is a yellow fully water-soluble powder with total amino acids ≥30%, free amino acids ≥20%, polypeptides+small peptides ≥10%, Ca ≥15%, B ≥1%, Zn ≥2%, pH 6-8, and chlorine-free. Using amino acid chelation technology, Ca, Zn, and B exist in chelated form, allowing direct crop absorption with a rate far exceeding ordinary inorganic micronutrient fertilizers.

Core Advantages

  • Calcium, zinc, and boron supplementCalcium≥15%, Zinc≥2%, Boron≥1%, supplying medium element calcium and trace elements zinc and boron in one application
  • Amino Acid Chelation ProcessCalcium, zinc, and boron are present in amino acid chelated form, offering good stability and resistance to soil fixation.
  • High-content organic nutritionTotal AA≥30%, Free AA≥20%, Polypeptide+Small Peptide≥10%, providing rich organic nutrition and enhancing crop stress resistance
  • High absorption and utilization rateAmino acids directly participate in crop metabolism, with nutrient absorption rates reaching 3-5 times that of common inorganic fertilizers
  • Fully Water-SolubleYellow fully soluble powder, dissolves quickly with no sediment or residue, suitable for all irrigation systems.
  • Chlorine-Free FormulaChloride-free, suitable for chloride-sensitive cash crops and fruit trees

Application Reference

Drip irrigation application (recommended)

Fully water-soluble formula, ideal for protected agriculture and precision fertilization; amino acid chelated medium elements are directly absorbable by crops

  • Concentration: 0.5 — 1 g/L irrigation water.
  • Application rate: 2 — 5 kg/mu/time
  • Frequency: every 10–15 days
  • Note: Can be used together with water-soluble macro-element fertilizers.

Foliar Application

Quickly replenishes calcium, zinc, and boron, corrects deficiency symptoms, especially suitable for fruit development and flowering-fruiting stages.

  • Dilution ratio: 1:1000 – 1:2000
  • Application rate: 30 — 60 L/mu
  • Time: morning or evening, avoid high temperatures
  • Note: Apply 2–3 consecutive sprays during flowering and fruit development for best results

Fertigation

Apply via fertigation with watering, suitable for fruit trees, vegetables, and other cash crops to supplement secondary nutrients.

  • Dosage: 5 — 10 kg/mu/time
  • Dilution ratio: 1:100 – 1:200
  • Timing: Critical growth stages of the crop
  • Note: Small amounts applied frequently yield better results

Water-soluble fertilizer compounding

Use as a source of secondary nutrients in combination with water-soluble NPK fertilizers for balanced nutrition.

  • Use in combination with water-soluble NPK fertilizers
  • Addition ratio: 3 — 8%
  • Suitable for melons, vegetables, and fruit trees
  • Can be used alone or in combination with other amino acid products.

Applicable Crops & Recommended Dosage

Crop Type Representative Crops Drip Irrigation Rate Foliar spray dosage Application period
Fruit Trees Apple, pear, peach, grape, citrus 3–5 kg/mu 1000 — 2000 times Young fruit stage, expansion stage, after harvest
Vegetables Tomato, cucumber, pepper, eggplant 2–4 kg/mu 1000–1500x dilution Seedling, flowering, and fruiting stages
Melons and Fruits Watermelon, melon, strawberry 2–4 kg/mu 1000–1500x dilution Vine elongation stage, flowering stage, expansion stage
Oil Crops Rapeseed, peanut, soybean 2–3 kg/mu 1000–1500x dilution Flowering and pod-setting stage
Root and Tuber Crops Potatoes, carrots, beets 2–3 kg/mu 1000–1500x dilution Tuber Formation & Bulking Stage
Application precautions
  • Store in a cool, dry place away from direct sunlight; use promptly after opening.
  • Boron dosage must be carefully controlled to avoid toxicity.
  • Can be mixed with most fertilizers and pesticides, but a small-area test is recommended before use.
  • For foliar spraying, it is recommended to test on a small area first to confirm no phytotoxicity before large-scale use.
  • Before drip irrigation, filter the solution to prevent impurities from clogging the drippers.

FAQ

Calcium, zinc, and boron have a close synergistic relationship in crops:

  • Mutual promotion of absorptionBoron promotes calcium absorption and transport, zinc is involved in auxin synthesis, and their synergy enhances nutrient utilization efficiency
  • Jointly involved in crop metabolismCalcium is a key component of cell walls, zinc activates various enzymes, and boron promotes flowering and fruit setting.
  • Prevention of Comprehensive Nutrient DeficiencyDeficiencies of multiple elements can affect crop growth; simultaneous supplementation prevents physiological disorders such as fruit cracking, bitter pit, little leaf disease, yellowing, and bloom without fruit set.
  • Improve fruit qualityCalcium, zinc, and boron combined significantly improve fruit firmness, storage tolerance, and appearance quality.

Therefore, supplementing multiple elements simultaneously is far more efficient than supplementing them individually.

The main difference lies in chelation process and nutrient form.

  • Common Secondary and Micronutrient FertilizerExisting in inorganic salt form (e.g., calcium nitrate, borax, zinc sulfate), crops must convert them into absorbable forms, resulting in lower absorption rates and susceptibility to precipitation with phosphates in the soil.
  • Amino Acid Chelated Ca Zn BExisting in amino acid chelated form, Ca, Zn, and B are "wrapped" by amino acid molecules, offering high stability, resistance to soil fixation, and direct crop absorption at a rate 3-5 times that of ordinary inorganic fertilizers.

Amino acids themselves are an organic nitrogen source directly usable by crops, significantly improving stress resistance and quality

The timing for calcium, zinc, and boron supplementation should be determined based on the crop growth cycle and nutrient requirements:

  • Seedling StagePromotes seedling growth and enhances photosynthesis
  • Flowering PeriodPromotes pollen germination and fertilization, improving fruit set rate
  • Young Fruit StagePromotes young fruit cell division and development, laying a foundation for fruit enlargement
  • Fruit expansion periodPromotes rapid fruit enlargement, prevents cracking and malformation
  • After HarvestReplenish tree nutrition, restore tree vigor

Recommended for use in advance during key calcium, zinc, and boron demand periods; prevention is better than correction.
