Developing a soil quality index to compare soil fitness for agricultural use under different managements in the Mediterranean environment
Due to increasing land-use pressures, soil-quality assessment is in growing demand, thus a standard set of procedures to assign a soil quality index (SQI) would be beneficial. In this study, the effectiveness of different managements in upholding soil quality (for crop productivity) was compared using soil quality indicators incorporated systematically to determine a SQI. The managements includ...
متن کاملPersistence of 2,4-D and 2,4,5-T in chaparral soil and vegetation.
The behavior of 2,4-D and 2,4,5-T has been widely studied in the cool moist forests of the Pacific Northwest (NORRIS 1971). Little data are available, however, for the unique conditions in arid southern California, where the two compounds are used for maintenance of fuelbreaks in chaparral vegetation. Reported here is a study to determine the movement and persistence of 2,4-D and 2,4,5-T in soi...
