In addition, there are three main reasons for the deficiency(hydroponics trays cheap): one is due to the insufficient content of a certain nutrient element in the soil; the other is that although there is such a nutrient element in the soil, its soluble or absorbable part is too small to cause nutrient deficiency(7 gallon plant pot). Third, the poor physical and chemical properties of soil affect the development of soil fertility and hinder the absorption of nutrient elements.
