The amount of micro-fertilizer is extremely small, and how to apply it evenly is a problem that plagues many vegetable farmers. Some farmers think that the fertilizer is too little, and there is no way to use it. Therefore, it is not necessary or increased the amount of micro-fertilizer, which is unfavorable for the normal growth of vegetables. In fact, the uniform application of micro-fertilizer is also very simple, because most of the micro-fertilizers are soluble, and the vegetable farmers can spray the dissolved fertilizer on the ground after the base fertilizer is sprinkled, and plow the soil into the soil together with the base fertilizer; The micro-fertilizer is dissolved in the bucket and is applied with water when watering.
