Does rotational bale grazing affect the distribution of soil nutrients across pastures?

open access: yesCrop, Forage &Turfgrass Management, Volume 12, Issue 1, June 2026.
Abstract Rotational bale grazing (RBG), the strategic feeding of round hay bales directly on pasture with controlled access, offers an alternative to continuous winter hay feeding in a single paddock. This study evaluated RBG's potential to redistribute nutrients by increasing soil concentrations in field areas with lower phosphorus (P) and potassium ...

Comparing the effects of soil test interpretations for P and K on a creeping bentgrass putting green

open access: yesCrop, Forage &Turfgrass Management, Volume 12, Issue 1, June 2026.
Abstract Soil testing provides golf course superintendents with the information needed to apply fertilizers at optimal rates, thereby avoiding nutrient deficiencies and unnecessary applications. However, nutrient rate recommendations vary depending on how soil test results are interpreted.

Should cotton growers apply full nitrogen rate when using broiler‐litter as soil amendment?

open access: yesCrop, Forage &Turfgrass Management, Volume 12, Issue 1, June 2026.
Abstract Nitrogen plays a critical role in cotton (Gossypium hirsutum L.) production. Interest in using broiler (Gallus gallus domesticus) litter has increased in recent years due to its nutrient and soil health benefits. However, growers typically do not discount the N present in broiler litter and apply a full dose of fertilizer N.
