...Also, in soils that are deficient in trace elements such as copper, zinc, iron, and manganese, even if small amounts are applied to the soil, they are easily rendered unavailable and have little effect, so foliar spraying is often more effective. In Japan, some trace elements other than manganese and boron are not allowed to be mixed into regular fertilizers for sale, but are allowed to be mixed into liquid compound fertilizers used for foliar spraying, etc., and are called liquid trace element compound fertilizers. The production volume of liquid compound fertilizers is about 1,000 tons per year, and there are more than 50 types of foliar spray fertilizers, and the total amount of at least two of the following components is guaranteed to be at least 10%. ...
