dc.description.abstract [EN] Two biochars, one from forest waste (BCH-FW) and the other from olive mill waste (BCH-OMW), and one hydrochar from forest waste (HYD-FW) were analyzed from the horticultural and environmental point of view. Several incubation assays were performed to foresee the material evolution when used as soilless growth media. HYD-FW was slightly alkaline and rich in nutrients and showed high microbial respiration Moreover, it did not caused N immobilization but N mineralization which contradicts previous reports. Biochars were highly alkaline. BCH-FW was poor in nutrients whilst BCH-OMW was saline and rich in soluble cations. Both materials had low respiratory activity, similar to that of coir fibre (CF). Whilst BCH-FVV and CF immobilize N, BCH-OMW did not. Both biochars captured CO2 from the atmosphere, particularly BCH-OMW, which concomitantly showed a decrease in soluble cations. We conclude that pure hydrochar does not immobilize N and that alkaline biochars act as CO2 traps. (C) 2014 Elsevier Ltd. All rights reserved. es_ES
