Abstract
Crushed basalt and tuff were found to significantly improve the iron nutrition of peanuts grown in pots of highly calcareous soil. At a rate of 1/2% powdered rock (by weight), chlorophyll contents were double those of plants grown in untreated soil. At rates of 5% by weight, the effect of the rock powders was equal to that of FeEDDHA. The effectiveness of the rock powders was lower in the second crop on the same soils.
