Soil fertility investigations on soil solution composition and nutrition of sweet corn and onions

Creator:

McAndrew, David Wayne

Abstract:

Laboratory incubation studies and field studies with sweet corn and onions were undertaken to evaluate interactions of lime, phosphorus (P), and copper (Cu). Eight soils were incubated at a constant temperature of 21 °C with combinations of band placed monocalcium phosphate (MCP), ammonium sulfate (AmS), and copper sulfate pentahydrate (CSPH)...

N fertilizer effects on soil solution Mn and Mn response of barley and oats

Creator:

Petrie, S. E.

Abstract:

A series of field experiments was established in 1978, 1979, and 1980 on Lower Klamath Lake where Mn deficiency of oats had been observed in previous years. The pH of the soils ranged from 7.6 to 8.3 and the organic matter content was between 17 and 19%. The objectives of...
