Effect Of Lime Quality On Soil Ph Changes, Monroe Rasnake
Soil Science News and Views
Quality of a liming material depends primarily on two factors - purity and size of the individual particles. Purity is an indication of how much active material is present. Particle size determines how fa st the lime can dissolve and react with soil acidity.

Current Research On Band Application Of Fertilizer To Burley Tobacco, J. L. Sims
Soil Science News and Views
Present Status: Generally, past research conducted in the United States has shown that only one-half to two-thirds as much fertilizer is required to produce maximum crop yields when the fertilizer is properly banded as when it is broadcast. However, the magnitude of plant response to banding compared to broadcast applications varies widely with soil nutrient levels, soil temperature, soil pH, and the mobility of the nutrient being applied. Greatest benefits from banding result from (a) applications to soils having low or very-low soil test levels of the nutrient in question, (b) applications to crops grown in cool climates, (3) applications …
