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.

2、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.

3、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.

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.

Grower 101: Calculations Part III: Fertilizers

The 100 gals. of diluted fertilizer solution is composed of 99 gals. of water plus 1 gal. of stock solution. A 1:200 injector will deliver 200 gals. of diluted fertilizer for each gallon of concentrated stock solution (or 100 gals. of diluted solution per one-half gal. of stock).

How to Calculate a Fertilizer Ratio

Thus, the fertilizer ratio that best fits this recommendation is 3-1-1. As demonstrated in the first paragraph, you can match the fertilizer ratio for this recommendation with a fertilizer grade by dividing each number in the fertilizer grade by the lowest number in the grade.

Selecting the Right Water

The best guide when selecting an appropriate water-soluble fertilizer is to balance the proportion of nitrogen in the ammoniacal form (acid) against the irrigation water alkalinity (base).

FERTILIZER CALCULATIONS AND PRACTICE QUESTIONS

For a 1:100 injector, the fertilizer in the stock tank is 100 times more concentrated than the water that the plants will receive. This means that if a plant receives fertilizer at 200 ppm nitrogen, in the stock tank this will be mixed at 20,000 ppm nitrogen.

Water Soluble Fertilizer Calculator

Whether you are a home gardener, a professional landscaper, or a commercial farmer, this calculator streamlines the process of determining the correct amount of fertilizer to use based on your water volume and nutrient requirements.

Water

When preparing a fertilizer solution, it is recommended to start by adding about 70% of the required water volume, preferably hot water, to the container. Then, add the measured amount of fertilizer and agitate the mixture using a paddle mixer or other suitable methods.

Determining the suitable amount of water-soluble powder fertilizer (WSPF) to mix with one ton of ammonia water involves understanding dilution ratios and application methods. First, it is essential to clarify that ammonia water, a solution of ammonia gas in water, is typically used as a chemical fertilizer rather than a direct plant nutrient. ammonia water can react with other chemicals to produce nitrogen-based fertilizers, such as urea or ammonium nitrate.

Chemical Properties of Ammonia Water

Ammonia water (NH₄OH) is a weak alkaline with corrosive properties. In agriculture, it is commonly used as a nitrogen fertilizer. It contains ammonia (NH₃) and sodium hydroxide (NaOH), where ammonia serves as a nitrogen source for plant growth.

Role of Water-Soluble Powder Fertilizer

Water-soluble powder fertilizer (WSPF) refers to liquid nutrients that can be absorbed by plants to promote growth. These fertilizers are easily absorbed by plant roots and transported to other parts, providing essential nutrients.

Calculating Fertilizer Ratios

To ensure plants fully absorb nutrients from both ammonia water and WSPF, appropriate dilution ratios must be calculated. These ratios depend on factors such as soil type, crop requirements, and climatic conditions. Generally, concentrated ammonia water must be diluted with water before application.

Dilution Ratio for Ammonia Water

Assuming the use of 1 ton (1,000 liters) of ammonia water, the following steps determine optimal dilution:

1. Soil pH: Most plants prefer neutral or slightly acidic soil (pH 6.0–7.0). If soil is overly acidic or alkaline, lime or sulfur may be added to adjust pH.
2. Target Crop: Nitrogen requirements vary by crop. Leafy vegetables, for example, demand more nitrogen than other crops.
3. Climate: Drier regions may rely more on nitrogen, while wetter areas might require additional phosphorus or potassium.

Example Calculation for Nitrogen Enhancement:

• Target Soil pH: Assume ideal pH is 6.5 (based on soil tests).
• Crop Nitrogen Demand: Assume the crop requires 0.5 grams of nitrogen per kilogram of dry matter.
• Ammonia Water Volume: [ ext{Ammonia Volume} = frac{0.5, ext{g N}}{1,000, ext{g dry matter}} imes 1,000, ext{L} = 5, ext{L} ]
• Diluted Ammonia Concentration: [ ext{Concentration} = frac{5, ext{L}}{1,000, ext{L}} = 0.005, ext{mol/L} ]
• WSPF Dilution: If WSPF has a 0.5% active ingredient concentration: [ ext{WSPF Concentration} = frac{0.5, ext{g active ingredient}}{1,000, ext{L}} = 0.0005, ext{g/L} ]
• Total Dilution Factor: [ ext{Total Dilution} = ext{Ammonia Dilution} imes ext{WSPF Dilution} = 5000 imes 100 = 500,000, ext{times} ]

Practical Considerations: Adjust for operational errors (e.g., under-application) and environmental factors.

Fertilization Recommendations

• Conduct soil tests to assess pH, nutrient levels, and crop needs.
• Follow the "small amounts, multiple applications" principle to avoid salt buildup or root damage.
• Monitor plant growth and soil moisture, adjusting strategies as needed.

The calculated ratios provide a general guideline, but actual application should be adjusted based on specific conditions. Consult agricultural experts or specialized fertilizer guides to ensure optimal nutrient delivery and healthy plant growth.
