CHEMICAL STRUCTURE AND EXPLANATION:
These products are fully water-soluble blended fertilizers formulated to meet the essential nutritional needs of plants. They are optimized blends of macro and micronutrients (nitrogen, potassium, sulfur, zinc, boron) for specific crop types and growth stages.
NKS (13.00.46 + 5 SO₃): Focuses on fruit quality, taste, and shelf life with its high potassium (K₂O) and sulfur (SO₃) content.
NKS (13.00.46 + 5 SO₃ + 2 Zn + 1 B): Builds on NKS with added zinc (Zn) and boron (B) micronutrients. Zinc supports root development and hormone synthesis; boron enhances pollen viability, flowering, and fruit set.
NK (25.00.05): Designed to accelerate and strengthen vegetative (green tissue) growth with its high nitrogen (N) content.
| Property | NKS (13.00.46 + 5 SO₃) | NKS (13.00.46 + 5 SO₃ + 2 Zn + 1 B) | NK (25.00.05) |
|---|---|---|---|
| Appearance | Crystalline/granular, white-light grey | Crystalline/granular, white-light grey | Crystalline/granular, white-light grey |
| Odor | Odorless or slight | Odorless or slight | Odorless or slight |
| Solubility | Fully water-soluble | Fully water-soluble | Fully water-soluble |
| pH (Solution) | Slightly acidic | Slightly acidic | Slightly acidic |
| Hygroscopicity | Moderate; may cake in humid environments | Moderate; may cake in humid environments | Moderate; may cake in humid environments |
| Stability | Stable under normal conditions | Stable under normal conditions | Stable under normal conditions |
All three products are fully water-soluble, providing nutrients in a form readily available for plant uptake. Their slightly acidic solution pH contributes to better nutrient availability in alkaline soils and irrigation water. Due to their hygroscopic (moisture-absorbing) properties, they may cake in humid environments, making proper storage conditions essential.
| Nutrient Element | NKS (13.00.46 + 5 SO₃) | NKS (13.00.46 + 5 SO₃ + 2 Zn + 1 B) | NK (25.00.05) |
|---|---|---|---|
| Nitrogen (N) | 13% | 13% | 25% |
| Phosphorus (P₂O₅) | 0% | 0% | 0% |
| Potassium (K₂O) | 46% | 46% | 5% |
| Sulfur (SO₃) | 5% | 5% | - |
| Zinc (Zn) | - | 2% | - |
| Boron (B) | - | 1% | - |
Formulation Notes: NKS products contain no phosphorus (P₂O₅). Their high potassium and sulfur content focuses on fruit quality and plant resilience. The NK product contains no sulfur, zinc, or boron; its high nitrogen and low potassium levels target vegetative growth.

| Application Method | Recommendation |
|---|---|
| Soil (Drip Irrigation / Fertigation) | Can be applied with irrigation water. Adjust dosage based on soil analysis and crop requirements. |
| Foliar Application | Dilute with water at recommended rates and apply as foliar spray. |

Application Notes:
Always conduct soil and leaf analyses before application.
Avoid foliar applications during high temperature and intense sunlight (prefer early morning or evening hours).
Products are fully water-soluble, so they do not cause clogging and can be used with all irrigation systems.

SUMMARY:
This Technical Data Sheet covers three different water-soluble blended fertilizer products:
NKS (13.00.46 + 5 SO₃): With high potassium (46% K₂O) and sulfur (5% SO₃), it improves fruit quality, shelf life, and plant resilience.
NKS (13.00.46 + 5 SO₃ + 2 Zn + 1 B): Contains the same high potassium and sulfur plus 2% zinc (Zn) and 1% boron (B). Supports flowering, fruit set, root development, and pollen viability.
NK (25.00.05): With high nitrogen (25% N), it accelerates and strengthens vegetative (green tissue) growth.
All three products are fully water-soluble and can be applied via drip irrigation, sprinkler, or foliar methods. Due to their hygroscopic nature, they must be stored in cool, dry, and moisture-free environments. Personal protective equipment (PPE) should be used during handling, and the manufacturer's MSDS must be carefully reviewed. Shelf life is 24 months under proper storage conditions.
CRITICAL WARNINGS:
PRODUCT SELECTION: Choose the product based on crop type, growth stage, and soil analysis results. Incorrect selection may cause yield and quality losses.
STORAGE: Moisture causes caking and handling difficulties. Always keep packaging tightly closed and stored in dry conditions.
APPLICATION TIMING: Apply foliar sprays during early morning or late afternoon when sunlight is less intense. Adjust dosage during high temperature and drought conditions.
SAFETY: Keep products away from children, foodstuffs, and animal feed. Use gloves, goggles, and dust mask during handling. If swallowed, seek immediate medical attention and DO NOT INDUCE VOMITING.
DOSAGE: Do not exceed recommended dosages. Over-fertilization can cause plant damage (burning) and environmental pollution.
DOCUMENTATION: Always read and understand the official Safety Data Sheet (SDS/MSDS) provided by the manufacturer/supplier before use.
