Rainfall seasonality and timing: implications for cereal crop production in Ethiopia

open access: yesAgricultural and Forest Meteorology, 2021
Rainfall seasonality and timing are key climatic features affecting crop yield in rainfed agriculture (RFA). We evaluated the dynamics of temporal rainfall attributes – the strength of seasonality, the date of onset, cessation, and duration of the rainy ...

Nitrogen Turnover on Organic and Conventional Mixed Farms [PDF]

open access: yes, 1995
Separate focus on crop fertilization or feeding practices inadequately describes nitrogen (N) loss from mixed dairy farms because of (1) interaction between animal and crop production and between the production system and the manager, and (2 ...

Mixed-Species Cover Crop Biomass Estimation Using Planet Imagery

open access: yesSensors, 2023
Cover crop biomass is helpful for weed and pest control, soil erosion control, nutrient recycling, and overall soil health and crop productivity improvement. These benefits may vary based on cover crop species and their biomass. There is growing interest

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

open access: yesFEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...
