Good management practices are essential if optimum fertilizer responses are to be realized. These practices include use of recommended varieties, selection of adapted soils, weed control, disease and insect control, good seedbed preparation, proper seeding methods, and timely harvest. Because of the influence of soil type, climatic conditions, and other...

An adequate soil fertility program will pay big dividends in the production of field corn, providing the recommended variety is seeded, weeds and other pests are controlled, and an adequate moisture level is maintained. Corn effectively uses the nitrogen built up by alfalfa or clover and the nutrients supplied by...
The effect of serial (multiple-year) organic matter (OM) amendment on soil properties has been described in some cropping systems, although less is known about the effect of serially amended field soils on soil-borne plant diseases. The objectives of this study were to describe the effects of the third and fourth...

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)...
