Abstract
The application of wastes from the wine-distillery industry as source of organic matter and nutrients could be a good option of agricultural management. This study is focused on soil nitrogen (N) mineralization after addition of compost derived from this industry at different doses (7, 13 and 20 t/ha). An aerobic soil incubation in controlled conditions was carried out to study N mineralization from the soil-compost mixture as well as isolating the compost from the soil. The data were fitted to a non-linear regression obtaining low values of potentially mineralizable N (N0) and constants of mineralization (k) (from 81 to 104 mg/kg and from 0.008 to 0.013 1/days for the soil-compost mixtures, and from 42 to 71 mg/kg and from 0.009 to 0.015 1/days for the increasing doses of compost) which indicates that it is a mature compost very resistant to mineralization. Nitrogen mineralized (NM) in the field during two growing seasons (2011 and 2012) of a melon crop was calculated through a N balance, taking into account N imputs and outputs in the soil-plant system. NM in the unamended plots accounted to 31 kg/ha and 24 kg/ha in 2011 and 2012, respectively, and increased proportionally to the dose of compost applied until 113kg/ha and 98 kg/ha in the consecutive years. The constants of mineralization obtained in the laboratory were adjusted by field temperatures to predict NM in the field and a general overestimation was observed. The best estimates were obtained when considering the mixture of soil and compost, which reflects the important role of the soil to evaluate N mineralization caused by the addition of organic wastes.
