Efeito da digestão anaeróbia e da estabilização com cal na mineralização do car...
Bancessi, Aducabe; Ribeiro, Henrique Manuel; Fangueiro, David; Duarte, Elisabeth; Cabral, Fernanda; Vasconcelos, ErnestoThis work aims to evaluate the N and C mineralization in a Haplic Arenosol amended with 3 different sewage sludge: mixture of primary and secondary sewage sludge (MSS), anaerobically digested sewage sludge (DSS) and anaerobically digested sewage sludge treated with quicklime (LimeDSS). Two aerobic incubations, one to follow N mineralization and the other one to assess CO2 emissions, were performed during 140 da...
Efeito da cinza de biomassa na dinâmica do C e N do solo de uma plantação de Pi...
Gómez-Rey, Maria Xesus; Madeira, Manuel; Coutinho, João; Vasconcelos, ErnestoEffects of wood ash (loose and pelleted) on chemical properties and microbial activity in an Arenosol from a Pinus pinaster plantation were assessed through laboratory incubation. Wood ash was applied at a rate of 0, 4 and 8 g kg-1 soil both alone or together with N. Loose ash significantly increased pH values and extractable nutrients from the soil. Net nitrification was stimulated by it application. Amounts o...
O comportamento de pés-mãe de Eucalyptus globulus Labill. sujeitos a diferentes...
Vasconcelos, Ernesto; Ribeiro, H.M.; Ramos, A.; Coutinho, J.In Portugal the traditional propagation of Eucalyptus globulus Labill (E. globulus) by seed is being replaced by vegetative propagation by stem cuttings. However, for E. globulus, there is no sufficient information related to the management of mother plant fertilization. So, it is important to study the relationship between the fertilization of the mother plant and the rooting ability of the cuttings. With the ...
