Development of forest structure and leaf area in secondary forests regenerating on abandoned pastures in Central Amazonia [PDF]

, 2005
The area of secondary forest (SF) regenerating from pastures is increasing in the Amazon basin; however, the return of forest and canopy structure following abandonment is not well understood. This study examined the development of leaf area index (LAI),

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

Crop, 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.

Agronomic responses and botanical composition of warm‐season annual forages managed under contrasting harvest strategies

Crop, Forage &Turfgrass Management, Volume 12, Issue 1, June 2026.
Abstract Warm‐season annual (WSA) forages enhance the summer forage supply in subtropical livestock systems. The objective of this study was to determine forage mass (FM), nutritive value, nitrogen (N) yield, and botanical composition in 12 forage mixtures managed under two harvest strategies (simulated grazing vs. baleage). A randomized complete block

Correlation and calibration of Mehlich‐3 sulfur for Kentucky bluegrass

Crop Science
Abstract Sulfur (S) is a crucial macronutrient for turfgrass growth, and declining atmospheric deposition has increased the risk of S deficiency. Reliable Mehlich‐3 soil test interpretations for S are lacking for turfgrass.
