Planted pollinator habitat in agroecosystems: How does the pollinator community respond?

open access: yesFrontiers in Ecology and Evolution, 2023
Pollinators are important both ecologically and economically. Nonetheless, documented pollinator population decline threatens ecosystem functioning and human well-being.

Effect of environmental factors on the abundance variations of two native rodents in agricultural systems of Buenos Aires, Argentina [PDF]

open access: yes, 2019
Our aim was to assess the effect of environmental factors on short temporal abundance variations of the two most abundant native rodents of agricultural agroecosystems, Akodon azarae and Calomys laucha.

Interaction Between Nitrogen Forms, Phosphorus Forms, and Mineral Phases Drives Phosphorus Limitation and Uptake by Ryegrass in a Model System

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
Nitrogen addition shifts plant nutrition from nitrogen to phosphorus (P) limitation. Nitrate‐based nitrogen enhances P acquisition more effectively than ammonium through increased phosphatase activity, independently of pH changes. Organic P forms induce stronger P limitation than inorganic P.

Factors Influencing Soil Nitrification Process and the Effect on Environment and Health

open access: yesFrontiers in Sustainable Food Systems, 2022
To meet the global demand for food, several factors have been deployed by agriculturists to supply plants with nitrogen. These factors have been observed to influence the soil nitrification process.

Native bees (Hymenoptera: Apoidea) and berry polycultures: Studying farmers’ motivations for diversification and the impact of mass floral resources on pollinator communities [PDF]

open access: yes, 2017
Floral resource continuity is an important component in pollinator conservation. Mass blooms early in the season may bolster pollinator communities on sequentially flowering crops by creating a resource pulse in an agricultural landscape.

Synergistic effects of maize defoliation and common bean relay cropping in Western Ethiopia

open access: yesJSFA reports, EarlyView.
Abstract Background Maize defoliation is practiced to enhance crop management by improving light penetration, nutrient allocation, controlling weeds, and providing supplementary feeds for livestock. A rapid decline in soil fertility and low crop yields associated with maize‐based monocropping has prompted the recent introduction of maize common bean ...

Separation of trichothecene mycotoxins in a matrix of hemp (Cannabis sativa L.) seed, and quantification of deoxynivalenol in hemp grain infected with Fusarium graminearum

open access: yesJSFA reports, EarlyView.
Abstract Background Fusarium graminearum, one of the causal agents of ear rot in maize and head blight of cereal grains, also infects hemp (Cannabis sativa L. containing a maximum of 0.3% tetrahydrocannabinol or THC). This fungal pathogen produces trichothecene mycotoxins when it infects maize and cereal grains, but little is known about its production

Innovative Organic Fertilizers and Cover Crops: Perspectives for Sustainable Agriculture in the Era of Climate Change and Organic Agriculture

open access: yesAgronomy
Anthropogenic activities have resulted in land desertification in various regions of the world, leading to the degradation of critical soil characteristics such as organic matter (OM) content, nutrient stock, and prevailing biodiversity.
