What Is Water-soluble Fertilizer

In recent years, water-soluble fertilizers have been widely used in agricultural production due to their fast absorption and high utilization rate.
Today we will talk about what water-soluble fertilizer is and how to use it more effectively, for the reference of farmers.
1、 What is water-soluble fertilizer
Water soluble fertilizer is a kind of compound fertilizer that contains nitrogen, phosphorus, potassium, calcium, magnesium, amino acid, humic acid, Alginic acid and other elements and can be completely dissolved in water. It is easier to be absorbed by crops, and its absorption and utilization rate is relatively high.
More importantly, it can be applied to facility agriculture such as sprinkler and drip irrigation, achieving the integration of water and fertilizer, and achieving the effect of saving water, fertilizer, and labor.
2、 How to use water-soluble fertilizers for better results
1. Choose the best water-soluble fertilizer formula based on different growth stages of crops (1) Seedling stage: The seedling stage is the nutritional growth period of plants. To ensure healthy growth of plants, it is necessary to not only increase the content of nitrogen in the fertilizer formula, but also consider the balance of nitrogen, phosphorus, potassium, and trace elements.
During this period, high nitrogen formula and balanced formula can be alternately applied.
(2) Flower bud differentiation stage and flowering stage: To promote flower bud differentiation, make flower buds strong and increase the number of flowers, it is necessary to increase carbohydrates and carbon nitrogen ratio. It is recommended to use water-soluble fertilizers with high phosphorus formula at this stage.
(3) The fruiting period of the crop growth cycle: At this stage, fertilizers with high phosphorus and potassium content should be applied.
Applying calcium magnesium fertilizer can achieve the effect of improving quality, and for fruiting crops, it can also increase the sugar content of the fruit and enhance its disease resistance.
2. According to the physiological characteristics of different plants, professional water-soluble fertilizers are applied. For example, American scotts company develops special fertilizers for production according to the physiological characteristics of plants, such as Poinsettia special formula fertilizer, boron free formula fertilizer for pineapple cultivation, etc.
Producers choosing specialized fertilizers will have a good effect on improving product quality.
3. Targeted application of water-soluble fertilizers based on soil acidity and alkalinity can affect the effectiveness of nutrients and the absorption of nutrients by plants.
