How to use chemical fertilizers and things to remember

Chemical fertilizers are quite common in agriculture. Learning how to use chemical fertilizers is always necessary for farmers. Let's join VNT company to summarize the ways to use chemical fertilizers and notes when using them in the article below.

How to use chemical fertilizers properly

How to use chemical fertilizers according to type

Chemical fertilizers are divided into 3 types: nitrogen fertilizer, phosphate fertilizer and potassium fertilizer. Each type has its own characteristics but all have the following characteristics:

+) Contains few nutrients but a high nutrient ratio. For example, (NH4)2CO has only one nutrient, nitrogen, containing up to 46% pure N.

+) Easily soluble (except phosphorus) so it is easy to absorb, fast effective.

+) Has no effect on soil improvement, fertilizing with too much nitrogen and potassium will make the soil acidic.

How to use chemical fertilizers:

+) Due to the high nutritional ratio, easy solubility and fast effectiveness, nitrogen and potassium fertilizers are mainly used as top dressing. Nitrogen and potassium fertilizers can also be used as base fertilizers but must be applied in small amounts

+) Phosphate fertilizers are difficult to dissolve so they should be used as base fertilizers, to allow time for the fertilizer to dissolve

+) NPK mixed fertilizers can be used as base fertilizers or top dressings.

How to use chemical fertilizers according to fertilization method

Currently, chemical fertilization is carried out in two common methods: root fertilization and foliar fertilization. Depending on the different plant varieties, there are different ways of fertilizing. To apply chemical fertilizers effectively, you also need to pay attention to the following issues:

+) You should apply chemical fertilizers in holes, furrows or spread evenly on the ground...

+) For foliar fertilizers, spray evenly on the leaves. You can cover both sides of the leaves for better results.

+) Apply fertilizer evenly, avoid excess or lack

+) For the most effective foliar fertilization, you should use a sprayer. This helps the fertilizer to be sprayed evenly and the amount of spray can be adjusted, avoiding waste.

Note, always read the instructions before use and listen to advice from the fertilizer supplier to use the most standard dosage, providing enough nutrients for the plant safely.

Fertilize plants properly

How to use chemical fertilizers according to crop fertilization needs

Each growth and development period of the crop will have a different need for fertilizer. Fertilizing not according to the needs of the crop causes unnecessary excess fertilizer, directly affecting the soil environment and crop productivity.

Currently, the growth process of crops is divided into 3 main stages:

+) Stage 1: Fertilizing before planting

In this stage, the three children should fertilize before planting. This will help the soil become more fertile, creating favorable conditions for the crop to absorb and grow.

+) Stage 2: Top dressing when the plant is growing

To help the plant grow better such as growing new branches..., top dressing is very necessary. It directly affects the crop yield later.

+) Stage 3: Fertilizing to welcome the panicles or flowers

This is the stage when the plant is preparing to flower. Proper fertilization will help the plant grow strongly and produce more yield.

4 things to remember when using chemical fertilizers

1. Choose the right fertilizer

In fact, there are quite a few types of fertilizers for farmers to choose and use. However, for each type of plant and each type of soil, choosing the right type of fertilizer is extremely necessary.

Choosing the right type of fertilizer is an important factor that directly affects crop yield. Choosing the wrong type means it will cause many negative impacts. However, if you choose well, it will maximize the effectiveness to help crops achieve the best yield.

2. Apply chemical fertilizers at the right time and in the right dosage

Another factor that is worth considering is fertilizing at the right time. Each type of plant requires a different amount of nutrients at each stage of growth. Fertilizing at the right time will maximize the effectiveness of the selected fertilizer.

In addition, fertilizing in the right amount and following the instructions is also extremely important. Over-fertilizing will be wasteful, causing the plant to become overfed, and can kill the plant, especially when using micronutrient fertilizers. If you fertilize too little, the plant will lack nutrients, affecting crop yield. 

3. Exterminate pests before fertilizing

To maximize the effectiveness of chemical fertilizers, farmers need to eradicate pests before applying them. In addition, weather factors must also be considered. Fertilizers should be applied on sunny days to avoid the phenomenon of rain washing away fertilizers, causing waste.

4. Balanced chemical fertilization

In addition to the above factors, farmers also need to calculate to be able to apply chemical fertilizers in the most balanced way. Farmers should find out what nutrients their plants are lacking in order to provide effective supplementary methods. This will help the plants grow at the highest level and also improve fertility to protect the soil.
