Abstract
Efficient and detailed methods have been worked out for the preparation of synthetic and natural humates containing Fe, Al, Mg, Zn, Ni, Cu or other similar metals whose inorganic salts are ordinarily highly insoluble over some portion of the physiological range of pH of interest in connection with plant growth. 1 or 2 small applications of these humates will ordinarily supply sufficient Fe or similar metal to water or sand cultures to last throughout the entire period of growth. The metals in the form of humates are stable in alkaline and neutral as well as moderately acid culture media, and are not precipitated by phosphate.This publication has 2 references indexed in Scilit:
