Crops lack potassium fertilizer, can obtain 'chondropathy', are easy to fall down and are often troubled by pathogenic insects. The potash fertilizer may be used as base fertilizer, top dressing and foliage fertilizer.
Magnesium (Magnesium) is a medium element required by plants. The mass fraction of magnesium in the plant is 0.1-0.5%, the magnesium is a basic element of various enzymes in the plant body and is also an important composition component of chlorophyll, and the magnesium can promote nutrient substances to actively participate in photosynthesis.
The potash fertilizer has many benefits, but excessive application not only causes waste of precious resources, but also brings adverse effects to crops, such as antagonism of the crops to magnesium, difficult or impossible absorption and inhibition to the growth of the crops.
