Ammonia volatilisation from urease inhibitor-treated urea applied to sugarcane trash blankets.
Heitor Cantarella,Paulo Cesar Ocheuze Trivelin,Teodoro Leonardo Michelucci Contin,Fábio Luis Ferreira Dias,Raffaella Rossetto,Rafael Marcelino,Renato Badran Coimbra,José Antonio Quaggio +7 more
TL;DR: In this paper, the urease inhibitor NBPT slowed down urea hydrolysis and thus may help decrease ammonia losses in sugarcane fields, but the inhibitor was less effective when rain sufficient to incorporate urea into the soil occurred only 10 to 15 days or latter after fertiliser application.

Nitrogen in sugarcane derived from fertilizer under Brazilian field conditions
Henrique Coutinho Junqueira Franco,Rafael Otto,Carlos Eduardo Faroni,André Cesar Vitti,Emídio Cantídio Almeida de Oliveira,Paulo Cesar Ocheuze Trivelin +5 more
TL;DR: In this article, the authors evaluated the N derived from fertilizer (NDFF) during the sugarcane crop development, for both plant cane and first ratoon crop cycles, and found that NDFF contributed up to 40% of the total N in the plant cane at initial stages of development, and this contribution decreased during stages of maturity to approximately 10% of total N at harvest.

Mixed-species plantations of Acacia mangium and Eucalyptus grandis in Brazil: 2: Nitrogen accumulation in the stands and biological N2 fixation
Jean-Pierre Bouillet,Jean-Paul Laclau,José Leonardo de Moraes Gonçalves,Marcelo Zacharias Moreira,Paulo Cesar Ocheuze Trivelin,Christophe Jourdan,Eduardo Vinícius da Silva,Marisa de Cássia Piccolo,Siu Mui Tsai,Antoine Galiana +9 more
TL;DR: The development of mono-specific stands of Acacia mangium and Eucalyptus grandis was compared with mixed-species plantations, finding no evidence of N transfer from A. mangium to E. grandis and the most reliable estimation of N 2 fixation was likely to be achieved using the 15 N dilution method and sampling the whole plant.
Journal ArticleDOI
High soil penetration resistance reduces sugarcane root system development
Rafael Otto,A.P. Silva,Henrique Coutinho Junqueira Franco,Emídio Cantídio Almeida de Oliveira,Paulo Cesar Ocheuze Trivelin +4 more
TL;DR: In this article, the root density of sugarcane was analyzed in a mechanically harvested area and the relationship between the spatial distribution of physical soil properties and root density was analyzed using a multivariate boundary line approach.
