1、Chart

This fact sheet provides information on the amount of specific fertilizers (based on percent nitrogen), to mix in one gallon of water, to provide a concentrated solution. This concentrated solution is then used with a fertilizer injector to deliver a a dilute amount of fertilizer.

2、How Much Water Do I Mix With Fertilizer

Fertilizer injectors mix concentrated fertilizer with irrigation water at specific ratios, such as 1:100 (1 gallon to 100 gallons of water). Different ratios apply for small and large quantities, e. g., 30g urea with 100ml water or 50g per 20 liters.

3、Calculators for Mixing Water

When mixing water soluble fertilizer, put less than ½ of the total volume required into the tank, then add the fertilizer, then mix and add water to increase the total volume of stock to the required level.

4、Water Soluble Fertilizer Calculator

The water soluble fertilizer calculator helps you make a water soluble fertilizer solution to achieve a desired ppm of an element.

How to Dilute Fertilizer? The Right Way

Fertilizer dilution ratios indicate the proportion of fertilizer to water. These ratios are typically expressed as a ratio (e.g., 1:10, meaning 1 part fertilizer to 10 parts water).

WATER

The standard 10% stock solution is made from 10 kg of fertiliser diluted into to 100 litres of water or multiples of this. Stronger stock can be made up with warm water, but the standard stock mixes well with water at 100C and will not crystallize out at normal temperature.

Water

The recommended dilution rate is often around 1 tablespoon of fertilizer per gallon of water, but this may vary depending on the specific fertilizer and the type of plant being treated.

How to Use Water

The correct dilution ratio for water-soluble fertilizers depends on the type of fertilizer, crop requirements, and the manufacturer’s recommendations. Here are some general dilution guidelines:

Calculations for Water

If the injector ratio is 1:100, this means 1 gallon of fertilizer concentrate is added to each 100 gallons of irrigation water. The thing to remember in doing calculations for injectors is that the fertilizer will be at a higher concentration in the concentrate tank than in the irrigation water.

How Much Water Soluble Fertilizer to Use: A Comprehensive Guide

By following these guidelines and considering the factors mentioned above, you can effectively use water-soluble fertilizers to promote healthy plant growth and maximize yields.

Water-soluble fertilizer is a highly efficient and eco-friendly agricultural input. It dissolves rapidly in water and is readily absorbed by plants. Proper use of water-soluble fertilizers is critical for improving crop yields and quality. Below are guidelines for diluting 1 jin (0.5 kg) of water-soluble fertilizer:

1. Understand the Characteristics of Water-Soluble Fertilizer

Water-soluble fertilizers are fully soluble in water, featuring high nutrient content, rapid efficacy, and ease of use. When applying, control the dosage and dilution ratio to ensure optimal performance.

2. Determine the Application Rate

Adjust the fertilizer amount based on crop type, growth stage, and soil conditions. Generally, 5–10 kg per mu (~0.08–0.16 kg/m²) is sufficient for most crops. Fine-tune according to specific needs.

3. Dilution Ratio

Follow product instructions for dilution. Typically, 1 kg of fertilizer requires 1–3 liters of water. Adjust ratios contextually (e.g., crop sensitivity or soil moisture).

4. Mix Thoroughly

After dilution, apply the solution evenly around plant roots to ensure root contact. Avoid direct foliar or fruit spraying to prevent burning or phytotoxicity.

5. Timing of Application

Apply in the morning or evening to minimize heat stress on crops. Irrigate after application to aid absorption.

6. Frequency of Application

Due to its short residual effect, apply every 7–10 days. Adjust based on crop growth and soil conditions for best results.

7. Precautions

Monitor crops for signs of over-fertilization (e.g., leaf scorch, yellowing). If observed, reduce dosage or application frequency immediately.

8. Storage and Transportation

Store in a cool, dry, well-ventilated area away from sunlight and heat. Prevent packaging damage to avoid contamination or moisture exposure.

9. Environmental Protection

Use low-toxicity, residue-free products and avoid heavy metals or harmful substances to minimize environmental impact.

10. Training and Guidance

Farmers should receive professional training on proper usage and safety measures to maximize effectiveness and reduce losses.

Rational use of water-soluble fertilizers is vital for boosting crop productivity and quality. By following these guidelines, farmers can optimize fertilizer performance and achieve sustainable agricultural outcomes.
