Microbial Activity and Phosphorus Availability in A Subtropical Soil under Different Land Uses
Land use changes in the Everglades Agricultural Area (EAA) of south Florida may alter microbial activity and organic matter decomposition and ultimately influence the fate of P in soil. The objectives of this study were to determine effects of long-term cultivation and fertilization on microbial activity and P dynamics for contrasting land uses in the EAA. Soils (0-15 cm) under pasture for 100 ...
متن کاملPredicting Greenhouse Gas Emissions and Soil Carbon from Changing Pasture to an Energy Crop
Bioenergy related land use change would likely alter biogeochemical cycles and global greenhouse gas budgets. Energy cane (Saccharum officinarum L.) is a sugarcane variety and an emerging biofuel feedstock for cellulosic bio-ethanol production. It has potential for high yields and can be grown on marginal land, which minimizes competition with grain and vegetable production. The DayCent biogeoc...

Second, for every cm of rainfall, the free Sugarcane (Saccharum spp.) is the primary crop on the Histosols water in the soil profile of EAA Histosols can be exof the Everglades Agricultural Area (EAA), where periodic floods pected to rise about 10 cm (Glaz et al., 2002). Finally, and undesirably high water tables are increas...
