Optimizing Temperature Requirements for Clover Seed Germination

open access: yesAgrosystems, Geosciences & Environment, 2019
Core Ideas Temperature significantly affects the time and rate of clover (Trifolium spp.) germination. Germination and vigor were evaluated from −1.0 to 48.0°C at approximately 1.0°C increments.

Cotton rotation with single and multispecies cover crops affects yield, quality, and economic outcomes

open access: yesAgrosystems, Geosciences &Environment, Volume 9, Issue 4, December 2026.
Abstract Cover crops (CCs) have gained popularity in continuous crop production systems due to their agroecosystem benefits. This study evaluated the effects of nine CC treatments (single or multispecies) and no cover crop (noCC) on cotton (Gossypium hirsutum L.) growth characteristics, production, and economic returns in the Mid‐South United States ...

Seeding rate and reseeding potential of ball clover in binary mixtures with annual ryegrass

open access: yesCrop, Forage &Turfgrass Management, Volume 12, Issue 2, December 2026.
Abstract Legumes can form symbiotic associations with rhizobia and fix atmospheric nitrogen (N), contributing N to forage systems when grown in mixtures with non‐N‐fixing species. Ball clover (BC; Trifolium nigrescens Viv.) is a cool‐season annual legume with strong reseeding potential due to its production of hard seed.

Colony‐level pollen collection reflects visitation of managed bumble bees (Bombus impatiens) in strawberry fields and surrounding landscapes without reducing pollen limitation

open access: yesAgricultural and Forest Entomology, Volume 28, Issue 4, Page 636-647, November 2026.
We extracted pollen from colony beeswax to quantify season‐long, colony‐level resource use and tested how managed Bombus impatiens visitation and Rosaceae pollen collection relate to landscape context and strawberry pollination. Increased managed bumble bee visitation was not influenced by surrounding landcover, did not reduce pollen limitation and ...

Hydrologic, Plant and Soil Controls on Microbial Biomass and Enzyme Activities in a Natural and a Restored Freshwater Marsh of Eastern Ontario, Canada

open access: yesFreshwater Biology, Volume 71, Issue 10, October 2026.
ABSTRACT The hydrology and drainage history of freshwater marshes influence their soil properties and plant communities, which in turn affect microbial biomass and extracellular enzyme activities that regulate the biogeochemistry and functioning of the marsh. However, field reports examining the spatial differences and controls of microbial biomass and
