Spatiotemporal Distribution of Cattle Dung Patches in a Subtropical Soybean-Beef System under Different Grazing Intensities in Winter

Agronomy, 2020
Cattle dung distribution in pastoral ecosystems is uneven and affects nutrient availability to plants. Thus, identifying its spatiotemporal patterns is crucial to understanding the mechanisms underlying the system functioning.

Targeted keratin repair: A plant‐based approach to hair strength and surface restoration

International Journal of Cosmetic Science, EarlyView.
Application of Avena strigosa seed extract may reinforce keratin bonding, restoring hair fibre integrity by promoting intramolecular interactions at damaged sites of keratin proteins. Abstract Objective Chemical and thermal stress disrupts the intramolecular and intermolecular interactions that stabilize hair keratin, leading to structural degradation ...

Effects of irrigated cover crop cultivation period on common bean and soybean yield

Crop, Forage &Turfgrass Management, Volume 12, Issue 2, December 2026.
Abstract Cover crop inclusion is essential for improving soil management in tropical no till systems; however, the optimal duration of irrigated off‐season cultivation remains uncertain. This 3‐year field study evaluated nine cover crop species or mixtures and four cultivation periods (60, 75, 90, and 105 days) on biomass production, soil chemical ...

Forage mass, accumulation, and nutritive value of four perennial forages grown in a loblolly pine silvopasture in the Mid‐South United States

Agrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.
Abstract Establishing forage in loblolly pine (Pinus taeda L.) plantations has the potential to increase grazing acreage for cattle farms in the Mid‐South, but appropriate species selection still requires investigation. The objective was to evaluate forage mass, accumulation, and nutritive value of four perennial forage species, novel‐endophyte tall ...
