Effect of soil properties on copper availability to plants

Experimental glasshouse work involved examining the decrease in effectiveness of copper fertilizer in the soil through time. This seems to conflict with Mr. J.W. Gartrell\u27s programme of field trials which have shown no evidence for any decline in the effectiveness of the original application. 1. Ammonium cxalate extractable Cu. TABLE 3 - 77GL3.
