Soil Testing: Field, Sample And Laboratory Variability, Lloyd W. Murdock, Dan Kirkland, Phil Gillespie, Tim Gray
Soil Science News and Views
Soil testing has advanced as a science and has become a tool widely used in making fertilizer recommendations. One of the basic components for ensuring reliability of recommendations is calibration of soil test results to determine the proper match of fertilizer recommendations with the soil test level for each nutrient and crop. Generally, calibration has been accomplished on small plot areas and is quite accurate. Even though there is nutrient variability within small areas, the potential for variability is much greater on a field basis. An important factor in making reliable fertilizer recommendations is the assumption that the soil sample …

A test was started in Princeton in 1991 to observe the response of tall fescue to applications of nitrogen fertilizer and broiler litter. Five treatments were used: two and four tons of litter per acre, 100 lbs nitrogen (half in May and half in July), 100 lbs nitrogen plus soil test recommended rates of phosphate and potash (only 55 lbs of Phosphate applied in 1991) and a check which had no nutrients applied. The treatments began in May 1991 on an established stand of tall fescue on a fragipan soil at the U.K. Research and Education Center in Princeton.

Much interest has been shown by tobacco growers during recent months in fertilization and or other management practices that can be used to produce darker and redder cured leaf of burley tobacco. The purpose of this newsletter is to summarize what we know about some of the factors which affect color of cured leaf.
