Descripción
Two spent mushroom substrates (fresh, F-SMS, and composted in aerobic conditions, C-SMS) were annually applied for 4 yr at two different rates (8 and 25 Mg ha 1 as dry matter) to a vineyard soil (Typic Haploxerept) located near Logroño (Ebro Valley, La Rioja, Spain). Soil samples were collected at three depths (0?5, 5?15 and 15?25 cm), and analyzed for soil organic carbon (SOC), water-soluble carbon (WSC), potentially mineralizable nitrogen (PMN), N-NO3 and exchangeable N-NH4+, microbial biomass carbon (MBC), soil CO2 evolution (SR), ?-glucosidase activity (GLU) and soil mean weight diameter (MWD) of aggregates and water-stable aggregates (WSA). The highest rate of F-SMS and C-SMS (25 Mg ha?1) increased SOC, total nitrogen ( Total N), and labile organic forms (WSC and PMN) at 0- to 5- and 5- to 15-cm soil depth and microbiological activity (MBC and GLU) at 5- to 15-cm soil depth. There were no differences in soil CO2 emissions between F-SMS and C-SMS amendments. Applications of SMS did not increase the soil aggregation but increased the content of inorganic N in the soil surface (0?5-cm depth) layer. Factor analysis showed the positive relationship between labile organic matter fractions and N availability. Finally, application of SMS to semiarid vineyard soils facilities SMS recycling with simultaneous improvement in soil quality indicators related to labile organic matter and microbiologic activity. However, increased PMN and soil N-NO3 indicate a potential risks for N leaching from SMS amendments that should be further evaluated.
