Commodity risk assessment of Petunia spp. and Calibrachoa spp. unrooted cuttings from Kenya

EFSA Journal, Volume 22, Issue 4, April 2024.
Abstract The European Commission requested the EFSA Panel on Plant Health to evaluate the probability of entry of pests (likelihood of pest freedom at entry), including both regulated and non‐regulated pests, associated with unrooted cuttings of the genera Petunia and Calibrachoa produced under physical isolation in Kenya. The relevance of any pest for

Chemical composition and thermal stability of topsoil organic carbon: Influence of cropping system and tillage practices

European Journal of Soil Science, Volume 75, Issue 1, January–February 2024.
Abstract Agricultural management practices play a significant role in regulating the potential for soil organic carbon (SOC) sequestration. The objective of this study was to determine the effects of cropping systems and tillage practices on the chemistry and thermal stability of topsoil SOC in a long‐term field study in Ontario, Canada.

EFEITO DA TEMPERATURA DA ÁGUA NA QUEBRA DE DORMÊNCIA DE SEMENTES DE Canavalia brasiliensis

INFORME ECONÔMICO (UFPI), 2020
O Canavalia brasiliensis (feijão bravo-do-ceará) é uma leguminosa anual ou bianual que apresenta grande potencial de produção de biomassa e rusticidade durante períodos de deficiência hídrica, devido ao sistema radicular profundo, que absorve água e nutrientes em maiores profundidades do solo.
