Efeito da deriva de glifosato em capim marandu

Semina: Ciências Agrárias, 2021
A deriva de glifosato em plantas não resistentes à molécula do herbicida pode resultar em estímulo a determinadas características biológicas, caracterizando o fenômeno hormese. Com base nisso, avaliaram-se características produtivas e químico-bromatológicas em capim Marandu, simulando efeito de deriva, com doses subletais do herbicida glifosato.

Calibration and evaluation of a carbon net primary productivity module based on the SIMPLE model

Agronomy Journal, Volume 118, Issue 2, March/April 2026.
Abstract This study presents the carbon net primary productivity (CNPP) module, an implementation of the simple generic crop model (SIMPLE model) that we have extended to predict aboveground and belowground biomass production and carbon assimilation. The goal for this module is to predict biomass inputs at and below the soil surface, during and at the ...

Agronomic performance of maize and cover crops using composted sewage sludge to supply phosphorus

Agronomy Journal, Volume 118, Issue 1, January/February 2026.
Abstract The application of composted sewage sludge (CSS) in crop production offers a sustainable solution for nutrient recycling and reducing reliance on mineral fertilizers. This study evaluated the residual effects of CSS on phosphorus (P) bioavailability and agronomic performance of maize and cover crops in P‐fixing soils of the Brazilian Savannah (
