Factors affecting the consumption of roasted peanuts and products containing roasted peanuts were evaluated. A questionnaire was self-administered to 606 students and staff at Auburn and North Carolina A&T Universities. Fifty-six percent of respondents consumed roasted peanuts less than once per week while 31 percent consumed products containing roasted peanuts between once and twice weekly. Factors influencing the weekly consumption of roasted peanuts were age, gender, the use of the product as a side dish, crunchiness, convenience, and allergenicity (p < 0.05), whereas age, gender, the use of
Numerous studies have shown that, through transformation processes, organic phosphorus (P) plays an important role in P cycling and plant nutrition in temperate and tropical soils. Field and laboratory studies were conducted to evaluate the transformation of residual organic P in the 0-15 cm surface layer of a sewage sludge-amended Decatur silty clay loam, six years after the final of five consecutive annual sludge applications to field plots of Huntsville and Chicago sludges at 20 Mg/ha and 10 years after a single application of 100 Mg/ha of the same sludges. Two indicator crops, corn (Zea mays L.) and sudangrass (Sorghum sudanenses L.), were grown on these plots for one season. Treatment plots-control, fertilizer, Chicago 20 Mg ha/yr, Huntsville 20 Mg ha/yr, Chicago 100 Mg/ha, (single application), and Huntsville 100 Mg/ha (single application)-were sampled and organic P fractions determined. The P fractions followed the order of: moderately labile P > moderately resistant P > highly resistant P > labile P, both before planting and after harvesting irrespective of the soil treatment. Generally, the Chicago and Huntsville 20 Mg/ha/yr treatments resulted in higher soil organic P fractions than the same sludges at the 100 Mg/ha (single application) rate. The Huntsville sludge treatments also resulted in higher P fractions than the Chicago sludge treatments at the corresponding application rate. Percentages of the two major P fractions to the total organic P, calculated both before planting and after harvesting, revealed that by the end of harvesting, the moderately labile P had decreased by 5.5% while the moderately resistant P had increased by 4.7%, suggesting that transformation of the organic P could have occurred during cropping.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
