The impact of alum addition on organic P transformations in poultry litter and litter-amended soil.
Poultry litter treatment with alum (Al(2)(SO(4))(3) . 18H(2)O) lowers litter phosphorus (P) solubility and therefore can lower litter P release to runoff after land application. Lower P solubility in litter is generally attributed to aluminum-phosphate complex formation. However, recent studies suggest that alum additions to poultry litter may influence organic P mineralization. Therefore, alum...
متن کاملFecal bacteria and sex hormones in soil and runoff from cropped watersheds amended with poultry litter.
The application of poultry litter to agricultural fields can provide plant nutrients for crops and forage production, but fecal bacteria and the sex hormones estradiol and testosterone are components of litter that can be detrimental to the environment. Our objective was to determine if applications of poultry litter to small watersheds would contribute to the load of fecal bacteria and sex hor...
متن کاملArsenic in Soils and Forages from Poultry Litter-Amended Pastures
In regions of concentrated poultry production, poultry litter (PL) that contains significant quantities of trace elements is commonly surface-applied to pastures at high levels over multiple years. This study examined the effect of long-term applications of PL on soil concentrations of arsenic (As), copper (Cu), Zinc (Zn), and the uptake of these elements by bermuda grass grown on Cecil (well-d...
متن کاملAlum amendment effects on phosphorus release and distribution in poultry litter-amended sandy soils.
Increased poultry production has contributed to excess nutrient problems in Atlantic Coastal Plain soils due to land application of poultry litter (PL). Aluminum sulfate [alum, Al(2)(SO(4))(3).14H(2)O] amendment of PL effectively reduces soluble phosphorus (P) in the PL; however, the effects of these litters when added to acidic, sandy soils are not well understood. The objective of this study ...
متن کاملImpacts of different tillage practices on some soil microbiological properties and crop yield under semi-arid Mediterranean conditions
Effects of six tillage practices on some soil microbiological properties and crop yields were evaluated for a clay soil (Typic Haploxererts) under semi-arid Mediterranean conditions in a three year study (2006-2009). The experiment was designed as a completely randomized-block with three replications. Treatments were: conventional tillage with residue incorporated (CT1), conventional tillage wi...
