Water-soluble fertilizer is an efficient, environmentally friendly and easy to use fertilizer, which has many advantages such as improving crop yield and quality, enhancing crop resistance and improving soil structure, so it has been widely used in modern agriculture. This article will introduce in detail the types, characteristics, use methods and precautions of water-soluble fertilizers to help readers better understand and use water-soluble fertilizers.

Types of 1. water soluble fertilizer

Water soluble fertilizer is mainly divided into a large number of elements of water soluble fertilizer, medium elements of water soluble fertilizer and trace elements of water soluble fertilizer.

1. A large number of elements water soluble fertilizer

A large number of elements of water soluble fertilizer is a kind of nitrogen, phosphorus, potassium as the main components of the fertilizer, which nitrogen, phosphorus, potassium content between 20%-30%. This fertilizer can meet the needs of crops for a large number of elements and promote the growth and development of crops.

2. Medium element water soluble fertilizer

Medium element water soluble fertilizer is a kind of fertilizer with calcium, magnesium, sulfur and other medium elements as the main components. This fertilizer can meet the demand of crops for medium elements and improve the resistance and quality of crops.

3. Trace element water soluble fertilizer

Trace element water soluble fertilizer is a kind of iron, zinc, copper, manganese and other trace elements as the main components of the fertilizer. This fertilizer can meet the needs of crops for trace elements and improve the yield and quality of crops.

Characteristics of 2. water soluble fertilizer

Water soluble fertilizer has the following characteristics:

1. High efficiency: water soluble fertilizer has high nutrient content, which can meet the nutrient demand of crops and improve the yield and quality of crops.

Environmental protection: The use of water soluble fertilizer is irrigation, which will not pollute the environment.

3. Convenience: The use of water-soluble fertilizer is simple, only need to add water during irrigation.

4. Safety: The composition of water soluble fertilizer is safe and will not have a negative impact on crops.

The use of 3. water soluble fertilizer

The use of water soluble fertilizer is as follows:

1. Determine the amount of fertilizer: according to the growth stage of crops, soil conditions and climatic conditions and other factors to determine the amount of fertilizer. Generally speaking, 5-10kg of water soluble fertilizer is required per mu.

2. Choose the right type of fertilizer: Choose the right type of fertilizer according to the needs of crops and soil conditions. For example, for crops that require a large amount of nitrogen, phosphorus, and potassium, you can choose a large amount of element water-soluble fertilizer; for crops that require a large amount of elements such as calcium and magnesium, you can choose a medium amount of element water-soluble fertilizer; for crops that require trace elements such as iron and zinc, you can choose Trace element water-soluble fertilizer.

3. Dilute fertilizer: The selected water-soluble fertilizer is diluted according to the proportion required by the instructions, and then added to the irrigation water. In general, the diluted fertilizer concentration should be 0.5-1%.

4. Irrigation: The diluted fertilizer is added to the water during irrigation, and then irrigation is carried out. Generally speaking, the duration of each irrigation should be about 2-3 hours.

4. considerations

In the use of water soluble fertilizer need to pay attention to the following points:

1. Avoid excessive fertilization: excessive fertilization will lead to crop burning seedlings, excessive growth and other problems, affecting the growth and quality of crops. Therefore, in the use of water soluble fertilizer should be based on crop demand and soil conditions to determine the amount of fertilizer.

2. Avoid mixing with alkaline substances: water soluble fertilizer is generally acidic, if mixed with alkaline substances will lead to fertilizer failure. Therefore, in the use of water soluble fertilizer should avoid mixing with alkaline substances.
