More and more farmers realize that the micro-nutrient fertilizer(zinc sulfate) is very important to the plants, and they pay more attention to the trace elements supplement such as: Zn 、Fe( ferrous sulfate) and B and so on. However, lots of farmers aren’t familiar with the dosage and use it like NPK and other compound fertilizer, which will damage the plants very much.
Experts suggests: Vegetables need only a little micronutrient fertilizer such as for 667㎡，it needs 1-2kgs of zinc sulfate, 5kgs of ferrous sulfate. What’s more, the dosage is up to the plants’ varieties. Soybeans are sensitive to B and Mo elements.
How to fertilize equally is also the big problem for farmers. It is suggested that most of micronutrient fertilizer is soluble, and farmers should spray soluble fertilizer into soil and plough it with the base fertilizer; or solve the micronutrient fertilizer (zinc sulfate,ferrous sulfate) into the water and apply when watering.
