Nutrient leaching in a Colombian savanna Oxisol amended with biochar.
Nutrient leaching in highly weathered tropical soils often poses a challenge for crop production. We investigated the effects of applying 20 t ha biochar (BC) to a Colombian savanna Oxisol on soil hydrology and nutrient leaching in field experiments. Measurements were made over the third and fourth years after a single BC application. Nutrient contents in the soil solution were measured under o...
متن کاملToxicologic studies with swine fed corn grown on municipal sewage sludge-amended soil.
Over a 3-yr period 336 MT/ha of dried sewage sludge, from a municipal waste treatment plant, was applied in liquid form to land subsequently used to grow corn. The sludge contained 115 mg Cd, 4,200 mg Zn and 538 mg Ni/kg dry matter and comprised the solids remaining after treatment of the waste waters of approximately 260 industries as well as domestic users. Corn grain harvested from the plot ...
متن کاملMetal availability and uptake by sorghum plants grown in soils amended with sludge from different treatments.
Several factors depending on the sludge, the soil, or the combination of both substrates, may affect element availability to plants. In this study, an assessment was done of the effect of two sludges obtained by different processes (activated sludge and facultative stabilization pond) on heavy-metal availability and uptake by sorghum plants in soils with high and low copper contents. Results ob...
متن کاملCadmium, lead and zinc in growing rats fed corn leaf tissue grown on soil amended with sewage sludge or heavy metal salts.
Rats were fed, from weaning through 11 weeks of age, dried leaf tissue of corn plants grown on soil amended with regular NPK fertilizer (150-22-62), with 33.6 ad 67.2 metric ton/ha of sewage sludge or with salts of cadmium (10kg/ha), lead (25kg/ha), and/or zinc (50kg/ha). A very high proportion of the cadmium (cd) consumed was eliminated in feces. Only in rats fed diets containing leaf tissue f...
متن کاملArsenic and Lead Uptake by Vegetable Crops Grown on an Old Orchard Site Amended with Compost.
The potential for lead (Pb) and arsenic (As) transfer into vegetables was studied on old orchard land contaminated by lead arsenate pesticides. Root (carrot), leafy (lettuce), and vegetable fruits (green bean, tomato) were grown on seven "miniplots" with soil concentrations ranging from near background to ≈ 800 and ≈ 200 mg kg-1 of total Pb and As, respectively. Each miniplot was divided into s...
