Effects of two beet vinasse forms on soil physical properties and soil loss
چکیده انگلیسی

Two beet vinasse forms (fresh (BV) and composted with a cotton gin crushed compost (CV)) have been applied for 4 years on a Typic Xerofluvent under dryland conditions near to Sevilla city (Guadalquivir River Valley, Andalusia, Spain) and their effect on soil physical, chemical and biological properties and their repercussion on soil loss was studied. BV and CV were applied at rates of 5000, 7500, and 10,000 kg ha− 1 organic matter ha− 1, respectively. The application of CV to the soil resulted in improved some soil properties and soil loss decreased. However, when BV was applied soil physical properties deteriorated and soil loss increased. We think that the high amounts of monovalent cations, particularly Na+, and of fulvic acids in BV destabilized soil structure. These results show that the addition of soil organic matter not always prevents soil loss, and they suggest the preferential use of composted beet vinasse versus fresh vinasse under dryland conditions.
