Abstract
About 140 samples of soils and rocks collected from the central region of California have been analyzed for easily soluble Zn and Pb. Also Cu, Co, and Ni were determined in many of the samples. Available Zn found runs ordinarily 1-5 p.p.m. but sometimes much higher as in soils where vegetable debris has accumulated for many years, thus greatly increasing the Zn content of the top soil by accumulations of the Zn from organic matter. Subsoils usually contain less than top soils. Rock samples vary greatly in content of these metals. In many cases the amount of these metals in rocks associated with the soils was similar to that in the rocks, indicating that the soils had been developed from the rocks.
