Resumo: | Carbon and nitrogen from the soil microbial biomass play a significant role in the rotation of C and N, and promote nutrient cycling. Thus, the objective of this study was to evaluate changes in the soil microbial biomass with growing doses of cover plant straw species. The cover plants cultivated in the cerrado biome region were incorporated an Oxisol Ustox. The straw of each cover plant was incorporated at doses of 0; 10; 20 and 30 Mg ha-1. The soil basal respiration was determined by incubating, after 21 days. The microbial biomass carbon and nitrogen were determined by the method the microwave irradiation. The microbial biomass carbon and nitrogen contents in extracts were determined by the wet combustion method and Kjeldahl-N. The metabolic quotient was calculated as the ratio between soil basal respiration rate and microbial biomass C, and the microbial quotient as the ratio between soil microbial biomass C and total carbon of soil. The soil microbial population measured by the attributes of quality responds to the addition of the of grass and legume straws incorporated to the soil; The treatments that cause the greatest stress to the microbial population, at 21 days, mediated by the metabolic quotient, are guandu-anão at a dose of 10 Mg ha-1; Guandu-anão and Guandu fava-larga at 20 Mg ha-1 and Brachiária at a dose of 30 Mg ha-1; The best result regarding microbial attributes of soil quality evaluated was observed with the incorporation of all doses of the straw of Crotalaria-ocroleuca. |

O carbono e nitrogênio da biomassa microbiana do solo desempenham um papel significativo na rotação de C e N, promovendo o ciclo de nutrientes. Assim, o objetivo deste trabalho foi avaliar mudanças na biomassa microbiana do solo com doses crescentes de palha de cobertura. As plantas de cobertura cultivadas no bioma cerrado foram incorporadas a um Latossolo Amarelo Eutrófico. A palha de cada planta de cobertura foi incorporada em doses de 0; 10; 20 e 30 Mg ha-1. A respiração basal do solo foi determinada por incubação, após 21 dias. O carbono e nitrogênio da biomassa microbiana foram determinados pelo método da irradiação de micro-ondas, os seus teores de carbono e nitrogênio da biomassa microbiana nos extratos foram determinados pelo método de combustão úmida e Kjeldahl-N. O quociente metabólico foi calculado como a razão entre a taxa de respiração basal do solo e a biomassa microbiana, e o quociente microbiano a razão entre a biomassa microbiana do solo e o carbono total do solo. A população microbiana do solo medida pelos atributos de qualidade responde à adição de palhas de gramíneas e leguminosas incorporadas ao solo; Os tratamentos que causam maior estresse à população microbiana, aos 21 dias, mediados pelo quociente metabólico, são o guandu-anão na dose de 10 Mg ha-1; Guandu-anão e Guandu fava-larga a 20 Mg ha-1 e Brachiária na dose de 30 Mg ha-1; O melhor resultado em relação aos atributos microbianos de qualidade do solo avaliados foi observado com a incorporação de palha de Crotalaria-ocroleuca.
