Phytoremediation of Poultry Manure-Enriched Soils for Phosphorus Using Cowpea Genotypes
Journal of Crop Improvement, 2012Co-Authors: R. B. Dadson, I. Javaid, Fawzy Hashem, Jagmohan JoshiAbstract:The application of Poultry Manure to crops to obtain higher yields is a widely used practice in many Poultry-producing regions of the United States and other parts of the world. This practice often results in the enrichment of phosphorus (P) in soils, resulting in various environmental and ecological concerns. We evaluated several diverse cowpea (Vigna unguiculata Walp.) genotypes to explore their potential for the removal of P from Poultry Manure-enriched soils and the soils that had not received Poultry Manure applications. Cowpea genotypes, including Champion and White Acre, extracted higher amounts of P compared to other genotypes under field and greenhouse conditions in both types of soils. These genotypes could play an important role in P removal from Poultry Manure-enriched soils.

Potential of Corn Genotypes for Phosphorus Removal in Poultry Manure-Enriched Soils
Journal of Crop Improvement, 2011Co-Authors: R. B. Dadson, I. Javaid, Fawzy Hashem, Jagmohan JoshiAbstract:The repeated application of Poultry Manure to agricultural lands in Poultry-producing regions of the world has resulted in excess farm-level phosphorus (P) with various undesirable effects. To reduce high P accumulation in soil and its undesirable environmental consequences, plant-based P-remediation strategies have been suggested. Our objective was to determine the difference in P uptake in various genotypes of corn (Zea mays L.) harvested at the milk stage of grain formation in Poultry Manure-enriched soils. Field experiments were conducted during three growing seasons at two sites: One site had a history of heavy Poultry Manure applications during the past 10 years, and the other site had not received Poultry Manure applications. Results showed that genotypes 57K14 and DKC 64-11 exhibited superior P uptake in both amended and unamended soils. The superior P extraction of genotypes 57K14 and DKC 64-11 relative to that of other genotypes indicates that there is potential to improve P uptake in corn genot...

The value of Poultry Manure for wetland rice grown in rotation with wheat
Nutrient Cycling in Agroecosystems, 1996Co-Authors: Bijay-singh, Yadvinder-singh, M. S. Maskina, O. P. MeeluAbstract:Poultry Manure applied alone or in combination with urea at different N levels was evaluated as a N source for wetland rice grown in a Fatehpur loamy sand soil. Residual effects were studied on wheat which followed rice every year during the three cropping cycles. In the first year, Poultry Manure did not perform better than urea but by the third year, when applied in quantities sufficient to supply 120 and 180 kg N ha−1, it produced significantly more rice grain yield than the same rates of N as urea. Poultry Manure sustained the grain yield of rice during the three years while the yield decreased with urea. Apparent N recovery by rice decreased from 45 to 28% during 1987 to 1989 in the case of urea, but it remained almost the same (35, 33 and 37%) for Poultry Manure. Thus, urea N values of Poultry Manure calculated from yield or N uptake data following two different approaches averaged 80, 112 and 127% in 1987, 1988 and 1989, respectively. Poultry Manure and urea applied in 1:1 ratio on N basis produced yields in between the yields from the two sources applied alone. After three cycles of rice-wheat rotation, the organic matter in the soil increased with the amount of Manure applied to a plot. Olsen available P increased in soils amended with Poultry Manure. A residual effect of Poultry Manure applied to rice to supply 120 or 180 kg N ha−1 was observed in the wheat which followed rice and it was equivalent to 40 kg N ha−1 plus some P applied directly to wheat.

Ecotoxicity Bioassays on Leachates from Poultry Manure
Bulletin of Environmental Contamination and Toxicology, 2013Co-Authors: M. Delgado, R. Miralles Imperial, F. Alonso, C. Rodríguez, J. V. MartínAbstract:The main aim of this study was to evaluate the toxicity of different Poultry Manure landfill leachates, using a well-known toxicity test system (MS3). The bioassay was made using a battery of toxicity tests including acute toxicity with crustacean ( Daphnia magna ), algae ( Chlorella vulgaris ) and the in vitro toxicity test with the fish cell line RTG-2. On D. magna was high mortality for zero time and almost 100 % and 70 %–80 % mortality for sawdust and straw Poultry Manure respectively. No effects on C. vulgaris , was observed after the leachate exposure. None of the parameters considered: protein, EROD activity, β-gal activity and neutral red, showed differences between control test and the leachate collected from exposure to Poultry Manure.

Environmental assay on the effect of Poultry Manure application on soil organisms in agroecosystems.
The Science of the total environment, 2011Co-Authors: Miguel Delgado, Jose Valero Martin, R. Miralles Imperial, C. Rodríguez, F. AlonsoAbstract:This paper reports the effects produced on the organisms of the soil (plants, invertebrates and microorganisms), after the application of two types of Poultry Manure (sawdust and straw bed) on an agricultural land. The test was made using a terrestrial microcosm, Multi-Species Soil System (MS3) developed in INIA. There was no difference in the germination for any of the three species of plants considered in the study. The biomass was increased in the wheat (Triticum aestivum) coming from ground treated with both kinds of Poultry Manure. Oilseed rape (Brasica rapa) was not affected and regarding vetch (Vicia sativa) only straw Poultry Manure showed significant difference. For length only Vicia sativa was affected showing a reduction when straw was exposed to Poultry Manure. When the effect on invertebrates was studied, we observed a reduction in the number of worms during the test, especially from the ground control (13.7%), higher than in the ground with sawdust Poultry Manure (6.7%), whereas in the ground with straw Poultry Manure, there was no reduction. The biomass was affected and at the end of the test it was observed that while the reduction of worms in the ground control was about 48%, the number of those that were in the ground with sawdust Poultry Manure or straw Poultry Manure decreased by 41% and 22% respectively. Finally, the effects on microorganisms showed that the enzymatic activities: dehydrogenase (DH) and phosphatase and basal respiration rate increased at the beginning of the test, and the differences were statistically significant compared with the values of the control group. During the test, all these parameters decreased (except DH activities) but they were always higher than in the ground control. This is why it is possible to deduce that the contribution of Poultry Manure caused an improvement in the conditions of fertilization and also for the soil.
