C And N Stocks And Soil Organic Matter Dynamics In Succession Agroforestry Systems In Brazil

Autor: DANIEL HANKE, SHIRLEY G.S. NASCIMENTO, DEBORAH P. DICK, FERNANDO VIERO, MARIANA R. ÁVILA, LEONARDO P. DEBLE

Publikováno v: Anais da Academia Brasileira de Ciências, Vol 96, Iss 2 (2024)

Abstract Soil organic matter is closely linked to the quality of Agroecosystems and directly influences the agricultural production and the environmental conditions. Understanding of soil organic matter dynamics in agroforestry systems requires studi

MANAGEMENT OF IRRIGATION AND NITROGEN FERTILIZERS TO REDUCE AMMONIA VOLATILIZATION

Autor: Fernando Viero, Cimélio Bayer, Renan Costa Beber Vieira, Eduardo Carniel

Publikováno v: Revista Brasileira de Ciência do Solo, Vol 39, Iss 6, Pp 1737-1743 (2015)

ABSTRACT Nitrogen losses by ammonia (NH3) volatilization can be reduced by appropriate irrigation management or by alternative N sources, replacing urea. The objective of this study was to evaluate the efficiency of irrigation management and N source

Nitrogen Fertilization of No-Tillage Winter Cereals in the South-Central Region of Paraná, Brazil

Autor: Sandra Mara Vieira Fontoura, Fernando Viero, Renato Paulo de Moraes, Cimélio Bayer

Publikováno v: Revista Brasileira de Ciência do Solo, Vol 41, Iss 0 (2017)

ABSTRACT High winter cereal yields depend on an adequate supply of nitrogen (N). We developed a system for indicating N rates for wheat and barley in the South-Central region of the state of Paraná, Brazil, using results of 72 field experiments cond

Urease Inhibitor and Irrigation Management to Mitigate Ammonia Volatilization from Urea in No-Till Corn

Autor: Fernando Viero, Guilherme Batista Menegati, Eduardo Carniel, Paulo Regis Ferreira da Silva, Cimélio Bayer

Publikováno v: Revista Brasileira de Ciência do Solo, Vol 41, Iss 0 (2017)

ABSTRACT High nitrogen (N) losses by ammonia (NH3) volatilization from urea can compromise nitrogen fertilization efficiency and corn yield. The purpose of this study was to assess the effects of irrigation management and the addition of the urease i

Ammonia volatilization from nitrogen fertilizers in no-till wheat and maize in southern Brazil

Autor: Fernando Viero, Cimélio Bayer, Sandra Mara Vieira Fontoura, Renato Paulo de Moraes

Publikováno v: Revista Brasileira de Ciência do Solo, Vol 38, Iss 5, Pp 1515-1525 (2014)

Crop residues on the soil surface of no-till systems can intensify ammonia volatilization from N fertilizers applied to cereal crops. This study assessed the magnitude of N losses through ammonia volatilization from urea applied to no-till winter (wh
