Perdas de nutrientes associadas ao escoamento e aos sedimentos erodidos em encostas sob plantio direto
(Universidade Federal de Santa MariaBrasilAgronomiaUFSMPrograma de Pós-Graduação em Ciência do SoloCentro de Ciências Rurais, 2022-01-31)
No-tillage (NT) is widely used in areas of grain crops in tropical and subtropical regions.
However, crops fields under NT with low phytomass addition and without runoff control
practices are highly susceptible to ...
Losses of nutrients and anti-nutrients in red and white sorghum cultivars after decorticating in optimised conditions
(Taylor & Francis Ltd, 2018-04)
The aims were to optimise pearling process of red and white sorghum by assessing the effects of pearling time and grain moisture on endosperm yield and flour ash content and to assess nutrient and anti-nutrient losses ...
