MICROELEMENT COMPLEX FERTILIZER CONTAINING ORGANIC MINERAL

摘要

A trace element composite fertilizer containing organic minerals is provided to give minerals in an easily absorbable form to aged soil while preventing acidification of the soil or accumulation of salts. A trace element composite fertilizer containing organic minerals comprises: 5-80 wt% of deposits of red algae as a mineral source; and 3-20 wt% of a yeast solid cultured product obtained by inoculating and culturing 1-10 wt% of a culture of yeast Saccharomyces cerevisiae into and in a solid culture medium using defatted rice bran. The trace element composite fertilizer preferably comprises 10-60 wt% of the deposits of red algae.
