In recent years(plug trays wholesale), farmers have applied a large amount of chemical fertilizers, ignoring the combination of organic fertilizers and micro-fertilizers, resulting in soil compaction, alkalization, and increased salting, which changed the physical and chemical properties of the soil. Before the pests, the residues and roots of the crops (including the roots and leaves of the green onions) will produce some toxins, such as organic acids, aldehydes, alcohols and hydrocarbons(105 cell seed trays wholesale), during the decomposition of the rot, which will obviously inhibit the crops.
