The phosphorus (P) chemistry of biochar (BC)-amended soils is poorly understood. This statement is based on the lack of published research attempting a comprehensive characterization of biochar’s influence on P sorption. Therefore, this study addre

Soil organic C (SOC), the largest terrestrial C pool, has been shown to be sensitive to agricultural disturbance. In the Andean Puna, agricultural expansion is thought to be jeopardizing the large SOC stock sequestered in its soils. In this paper, we

Pine straw raking and fertilization effects on phosphorus (P) removals, total and mobile P in foliage and straw, and soil extractable P pools, were examined in 15 and 17-year-old slash pine ( Pinus elliottii Engelm.) stands on soils (an Ultisol and a

Quantifying soil organic carbon (SOC) inputs in the surface soil is a critical component for assessing the potential for carbon sequestration of managed pine forests. This study used a sequential exclusion of aboveground litter inputs (L, litter excl

Publikováno v: Biogeochemistry. 118:453-469

In the tropics, highly weathered soils with high phosphorus (P) fixation capacities predominate, reducing the P availability to plants. For this reason, understanding the cycle of P in the soil is important to develop management strategies that incre
