Associative diazotrophic bacteria inoculated in sugarcane cultivars: implicatio...
Lira,Dalliane Nogueira de Souza; Arauco,Adriana Miranda de Santana; Boechat,Cácio Luiz; Moitinho,Mara Regina; Lacerda,Julian Junio de JesusABSTRACT Sugarcane is one of the first activities of economic importance in Brazil. The understanding of the nutritional dynamics at different phenological stages of the sugarcane crop with the use of nitrogen-fixing bacteria has been one of the alternatives to decrease fertilizer consumption and increasing plant production. This study aimed to assess the morphophysiological attributes in the initial growth and...
ARBUSCULAR MYCORRHIZAL FUNGI ON THE INITIAL GROWTH AND NUTRITION OF Parkia Plat...
Porto,Dayara Lins; Arauco,Adriana Miranda de Santana; Boechat,Cácio Luiz; Silva,Adriano de Oliveira; Moitinho,Mara Regina; Farias,Séfora Gil Gomes deABSTRACT Parkia platycephala Benth. (Fava-de-bolota) found in areas of Cerrado-Caatinga transition, is a species with potential for feeding ruminants in arid regions. The objective of this study was to evaluate the effect of inoculation of arbuscular mycorrhizal fungi (AMF) on the initial growth and nutrition of P. platycephala Benth. seedlings under water stress. The experimental design was a randomized block ...
Temporal and Spatial Uncertainty of Erosion Soil Loss from an Argisol Under Sug...
Mendonça,Patrícia Gabarra; Teixeira,Daniel De Bortoli; Moitinho,Mara Regina; Silva Junior,João Fernandes da; Oliveira,Ismênia Ribeiro deABSTRACT The identification of erosion-susceptible areas is fundamental for the adoption of soil conservation practices. Thus, the best way to estimate the spatial pattern of soil erosion must be identified, in which the process uncertainties are also taken into consideration. The purpose of this study was to evaluate the spatial and temporal uncertainty of soil loss under two scenarios of sugarcane harvest man...
SPATIAL UNCERTAINTY OF NUTRIENT LOSS BY EROSION IN SUGARCANE HARVESTING SCENARIOS
Mendonça,Patrícia Gabarra; Silva Júnior,João Fernandes da; Oliveira,Ismênia Ribeiro de; Teixeira,Daniel De Bortoli; Moitinho,Mara ReginaThe assessment of spatial uncertainty in the prediction of nutrient losses by erosion associated with landscape models is an important tool for soil conservation planning. The purpose of this study was to evaluate the spatial and local uncertainty in predicting depletion rates of soil nutrients (P, K, Ca, and Mg) by soil erosion from green and burnt sugarcane harvesting scenarios, using sequential Gaussian simu...
Efeito do preparo do solo e resíduo da colheita de cana-de-açúcar sobre a emiss...
Moitinho,Mara Regina; Padovan,Milton Parron; Panosso,Alan Rodrigo; La Scala Jr,NewtonO solo é um dos principais compartimentos de carbono no ecossistema terrestre, capaz de armazenar quantidades expressivas desse elemento e, portanto, a compreensão dos fatores que contribuem para as perdas de CO2 em solos agrícolas é fundamental para determinar estratégias de redução das emissões desse gás e ajudar a mitigar o efeito estufa. O objetivo deste estudo foi investigar o efeito do preparo do solo e d...
