怎么制作螯合铁肥(制作螯合铁肥，让你的农作物摆脱缺铁烦恼)

Introduction

Iron is an important micronutrient required by plants to carry out various physiological and metabolic processes. However, deficiency of iron in soil can result in stunted growth, chlorosis, and reduced yields in crops. Chemical fertilizers containing iron can be used to address this issue, but they are expensive and can also have negative effects on the environment. One alternative solution is to make and use chelated iron fertilizer for improved plant growth without any harmful impacts on the environment.

What is Chelated Iron Fertilizer?

Chelated iron is a type of iron fertilizer that contains iron ions held tightly together by a chelating agent. This chelation process is done to increase the bioavailability of iron to the plants so that it can be easily absorbed by the roots. It also prevents the iron from reacting with other minerals present in the soil, making it more available for the plants.

How to Make Chelated Iron Fertilizer?

The following is a step-by-step guide on how you can make chelated iron fertilizer for your crops:

Materials Required:

Iron sulfate

Sodium hydroxide or potassium hydroxide

Distilled water

Chelating agent (such as EDTA or DTPA)

Sprayer or watering can

Steps:

Dissolve 100 grams of iron sulfate in one liter of distilled water.

In a separate container, dissolve 130 grams of sodium hydroxide in one liter of distilled water.

Mix the two solutions carefully in a large container. Make sure not to splash the solution on your skin or eyes as it can cause burns.

Gradually add the chelating agent to the mixture, while stirring continuously. The recommended amount is 20 grams of EDTA or 15 grams of DTPA per liter of the solution.

Keep stirring until the mixture turns into a greenish brown color, indicating that all the iron ions have been chelated.

Add the chelated iron fertilizer to a sprayer or watering can and use it to water your plants.

Benefits of Chelated Iron Fertilizer

Here are some of the benefits of using chelated iron fertilizer for your crops:

Improved plant growth and higher yields due to increased availability of iron for the plants.

Minimized risk of environmental pollution as chelation prevents the iron from reacting with other minerals and leaching into groundwater.

Cost-effective as it is easy to make at home using readily available materials.

Compatible with other organic fertilizers and pesticides, making it easy to integrate into your existing farming practices.

Conclusion

Chelated iron fertilizer is an effective and sustainable way of addressing iron deficiency in crops. With the right materials and instructions, it is easy to make at home and use for improved plant growth and yields. Using chelated iron fertilizer will not only benefit your crops but also help protect the environment from harmful impacts of chemical fertilizers.
