Unlike soybean, which is very efficient in fixing atmospheric N2 symbi... ... Repository: BDPA Publication year: 2013
Tamanho da parcela para estudos de recuperação de fertilizante 15N por capim-tanzânia. Author(s): MARTHA JúNIOR, G. B.; TRIVELIN, P. C. O.; CORSI, M. O entendimento da dinâmica do N em ecossistemas de pastagens pode ser melhorado por estudos em que se utilize a técnica do traçador 15N. Nesses experimentos, deve-se assegurar que o movimento lateral... ... Repository: BDPA Publication year: 2009
Dark septate endophytic fungi increase green manure-15N recovery efficiency, N contents, and micronutrients in rice grains. Author(s): VERGARA, C.; ARAUJO, K. E. C.; URQUIAGA, S.; SANTA-CATARINA, C.; SCHULTZ, N.; ARAUJO, E. da S.; BALIEIRO, F. de C.; XAVIER, G. R.; ZILLI, J. E. An understanding of the interaction between rice and dark septate endophytic (DSE) fungi, under green fertilization, may lead to sustainable agricultural practices. Nevertheless, this interaction is s... ... Repository: BDPA Publication year: 2018
