Resumo: Annual litter fall, the N, P, K, Ca and Mg content, litter decomposition rate and the nutrient use efficiency were studied in a deciduous seasonal forest, from the Serra Geral escarpments, in Santa Maria, Rio Grande do Sul. The annual litter fall reached 7.76 t/ha, with leaf fraction representing 66% of the total. Spring was the most intensive litterfall and nutrients deposition season. This annual deposition added to the forest soil about 206.7 Kg/ha of nitrogen, 11,2 Kg/ha of phosphorus, 37,8 Kg/ha of potassium, 269.2 Kg/ha of calcium and 29.9 Kg/ha of magnesium. The mean forest floor mass was 6.7 t/ha, the instantaneous decomposition rate (K) was estimated to be 1.16 and the time necessary to decay 50% of the total litter was around 7 months. The nutrient use efficiency, given by the biomass/nutrient rate to the N, P, Ca and Mg elements was lesser than those verified for others brazilians regions, showing that the primary productivity of the stand is not limited by the availability of the studied nutrients.

A produção anual de serapilheira, o conteúdo de N, P, K, Ca e Mg, a taxa de decomposição da serapilheira e a eficiência de utilização de nutrientes, foram estudadas numa floresta estacional decidual, situada nas encostas da Serra Geral em Santa Maria, Rio Grande do Sul. A produção anual de serapilheira foi de 7,76 t/ha, com a fração folhas representando aproximadamente 66% da produção total. A estação de maior deposição de serapilheira e nutrientes foi a primavera. Foram depositados anualmente no solo florestal 206 Kg/ha de nitrogênio, 11,2 Kg/ha de fósforo, 37,8 Kg/ha de potássio, 269,2 Kg/ha de cálcio e 29,9 kg/ha de magnésio. A quantidade média de manta acumulada sobre o solo totalizou 6,7 t/ha, a estimativa da taxa instantânea de decomposição (K)   foi de 1,16 e o tempo necessário para decomposição de 50% da serapilheira produzida, foi estimado em torno de 7 meses. A eficiência da utilização de nutrientes dada pela relação biomassa/nutriente para os elementos N, P, Ca e Mg, foi menor do que tem sido verificado em outras florestas do Brasil, indicando que a produtividade primária da floresta não é limitada pela disponibilidade dos elementos estudados.Universidade Federal de Santa Maria1999-03-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/28410.5902/19805098284Ciência Florestal; Vol. 3 No. 1 (1993); 35-64Ciência Florestal; v. 3 n. 1 (1993); 35-641980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/284/pdfCunha, Girlei Costa daGrendene, Luis AlmiroDurlo, Miguel AntãoBressan, Delmar Antônioinfo:eu-repo/semantics/openAccess2017-08-29T20:54:16Zoai:ojs.pkp.sfu.ca:article/284Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-08-29T20:54:16Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false
