Leaching of PCBs and Nutrients from Soil Fertilized with Municipal Sewage Sludge
Although sewage sludge is a rich source of nutrients for arable farming and soil improvement, it can also be a source of pollutants. The effects of the land application of sludge on the PCB and nutrient content of leachate were investigated using cylindrical 650 mm length columns filled with poor quality soil. Treatments included no fertilization (control), fertilization using a 62.5 t/ha dose ...
متن کاملYield and nitrogen leaching in maize field under different nitrogen rates and partial root drying irrigation
Irrigation water is limiting for crop production in arid and semi-arid areas. Furthermore, excess nitrogen (N) application is a source of groundwater contamination. Partial root drying irrigation (PRD) can be used as water saving technique and a controlling measure of groundwater N contamination. The objectives of this investigation were to evaluate the effect of ordinary furrow irrigation (OFI...
متن کاملEndogenous losses of nutrients.
(2) (3) These are not presented in the form of practical allowances. Hence, in practice, safety margins will be allowed to take account of such factors as variations in availability of nutrients in different samples of feeding-stuffs, possible losses during manufacture and storage of food, breed and individuality of animals, environmental circumstances and standards of husbandry. livestock has ...
متن کاملLeaching of heavy metal from native plants by chemical leachants
Plant biomass harvested after heavy-metal phytoremediation must be considered as a hazardous waste that should be contained or treated appropriately before disposal or reuse. This study provides an evaluation of extractants for the removal of lead from Abutilon Theophrastus biomass. The research was carried out a leaching study to determine the lead-extraction efficiency of the different leacha...
متن کاملEffect of Silicate Slag Application on Wheat Grown Under Two Nitrogen Rates
Field studies were established on the alluvial floodplain soils in Louisiana, from 2013 to 2015, to evaluate the effect of silicate slag applications on productivity of wheat (Triticum aestivum), under sufficient and high nitrogen (N) application rates. Treatments were arranged in a randomized complete block design, with four replications consisting of twelve treatments: a factorial combination...
