Resumo: | The inclusion of winter cover crops and fertilization with nitrogen to the soil can have an effect on their biological and microbiological attributes. The aim of this study was to evaluate biological and microbiological attributes in soil under different winter cover crops and nitrogen doses. The experiment was conducted at the Frederico Westphalen-RS campus of the Federal University of Santa Maria (UFSM) in a Rhodic Hapludox soil. The experimental design was a randomized block in factorial arrangement (2 x 10): 10 winter cover crops systems (Fallow [control], black oats, white oats, ryegrass, forage turnip, vetch, white lupine; black oat + forage turnip; black oat + vetch and black oat + vetch + fodder turnip), and two nitrogen rates in the form of urea applied in successive crops of beans common and maize, with four replications. We assessed the biological attributes (Margalef’s richness, Simpson’s dominance, Shannon’s diversity and abundance of organisms) and microbiological (carbon and nitrogen microbial biomass, basal respiration, metabolic quotient and microbial quotient of the soil). The fallow with wild species and white lupine showed greater Simpson’s dominance and abundance of organisms due to the increase in the number of individuals of the order Collembola. Vetch improved the biological attributes of the soil with increase in Collembola abundance and diversity of organisms of soil fauna. The application of nitrogen favored the microbial biomass carbon and reduced the metabolic quotient. |

O objetivo deste trabalho foi avaliar atributos biológicos e microbiológicos em solo submetido a diferentes plantas de cobertura de inverno e doses de nitrogênio. O trabalho foi conduzido no campus de Frederico Westphalen, RS da Universidade Federal de Santa Maria de abril de 2010 a outubro de 2013 em Latossolo Vermelho distrófico típico. O delineamento experimental foi em blocos ao acaso em arranjo fatorial (10 x 2) sendo 10 sistemas de plantas de cobertura de inverno: Pousio (testemunha com espécies espontâneas); Aveia preta; Aveia branca; Azevém; Nabo forrageiro; Ervilhaca; Tremoço branco; Aveia preta + Nabo forrageiro; Aveia preta + Ervilhaca e Aveia preta + Nabo forrageiro + Ervilhaca, e duas doses de nitrogênio na forma de ureia aplicados nos cultivos sucessivos de feijão e milho, com quatro repetições. Avaliaram-se os atributos biológicos da fauna edáfica (riqueza de Margalef, dominância de Simpson, diversidade de Shannon e densidade de organismos) e microbiológicos (carbono da biomassa microbiana, nitrogênio da biomassa microbiana, respiração basal, quociente metabólico e quociente microbiano do solo). O Pousio com espécies espontâneas e o tremoço resultaram em maior dominância de Simpson e densidade de organismos decorrente do aumento no número de indivíduos da ordem Collembola. A ervilhaca melhorou os atributos biológicos do solo com aumento no número de Collembola, abundância, riqueza e diversidade de organismos da fauna edáfica. A aplicação de nitrogênio favoreceu o carbono da biomassa microbiana e reduziu o quociente metabólico.UEL2017-05-02info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/2488210.5433/1679-0359.2017v38n2p649Semina: Ciências Agrárias; Vol. 38 No. 2 (2017); 649-658Semina: Ciências Agrárias; v. 38 n. 2 (2017); 649-6581679-03591676-546Xreponame:Semina.
