A SECRET BIOLOGICAL WARFARE PROGRAM The Secret Program Is Acknowledged Field Testing in the United States... [Pg.425]

The development of state-based soil testing programs to support agriculture in the United States relied on extensive research that assisted in the selection of appropriate soil testing methods and extractants, correlated the results of soil tests with plant production to allow for the interpretation of soil test results, and provided field calibration to develop nutrient recommendations for plant productiOTi based oti soil test results. Several methods have been developed to analyse soil for important soil physical, chemical, and biological properties that might affect agricultural production and soil quality (Table 2.2). [Pg.32]
