More than half of the U.S. sugarcane production comes from the Everglades Agricultural Area. The region’s high agricultural productivity is largely attributed to its fertile organic soils, Histosols, which contain up to 85% organic matter and provide essential nutrients for crop growth. However, decades of intensive farming coupled with hot and humid climate have led to significant soil loss. This article examines the impacts of farming on shallow organic soils in South Florida, exploring how reduced soil depth affects crop production and what strategies can help mitigate further soil loss.

Phosphorus (P) losses from agricultural land in the Prairie Pothole Region of Canada are dominated by P dissolved in snowmelt runoff water. This article presents a study showing that slope was not a major driver of P losses in snowmelt runoff. Earn 0.5 CEUs in Soil & Water Management by taking the quiz for the article.

The Texas Southern High Plains faces severe water limitations for agriculture, making efficient irrigation essential due to high evapotranspiration and declining groundwater from the Ogallala Aquifer. To address this, researchers developed a growth stage-based irrigation strategy for sweet corn, paired with biochar soil amendments, aiming to improve water productivity under drought-prone conditions. A two-year field study tested different irrigation levels and biochar rates to evaluate their effects on sweet corn growth, yield, and water efficiency.
