Rapid Phytate Quantification in Manures and Runoff Sediments using HPIC
… quantification of phosphorus (P) fractions in manures and agricultural runoff is vital to understanding P dynamics in the environment. Phytate is an organic form of P, with 6 phosphate groups, which is found in manures, but is difficult to quantify due to its affinity for complex formation with …

Nutrient and Bacterial Transport From Agricultural Lands Fertlized With Different Animal Manures
The increase of animal agriculture coupled with excess manure production, and the reduced availability of land has led to the over application of animal manure on agricultural fields. The excessive application of manure is responsible for nutrient and bacterial pollution of downstream waterbodies. …

Maximising the benefits of cover crops through optimising the use of rotations, nitrogen fertiliser and organic manures
… winter barley, select species respond to organic manures and sequester nutrients by transforming them into biomass. This means that application of slurry to cover crops is a more sustainable land management practice than applying them to fallow land. However, this is dependent on species choice …

Plant Medicine: The Use of Medicinal Plants as Green Manures in the Treatment of Streptomyces scabies Infection and Potato Scab Disease
… this experiment suggest the use of these green manures as a feasible, effective, organic means of potato scab control and warrant further research into the use of these and other medicinal plants in the treatment plant disease.</p>

The influence of fertilizers, manures, and lime on the plant and seed characters of wheat and corn and on their yield trend
Under the conditions of the Rotation Experiment with Fertilizers, the following results were obtained with corn: The phosphorous plat, complete fertilizer plat and the manure plats produced a much higher yield of corn than the check plat. Also, these plats produced a higher percentage of marketable …

Viability of weed seeds in manure and silage
Where manures are spread out on the fields, this problem is extremely important, but where manures are hauled out into the pastures or some pot hole and there burned or left, never to be utilized, weed seeds in manure are of no concern. However, the majority of the farmers do spread the barnyard …

Nitrogen values of liquid dairy manure and dry broiler litter as affected by preservation treatment
Five liquid dairy manures and five dry broiler litters were tested in the laboratory to determine the effects of four preservation techniques on the forms and concentrations of nitrogen. 300 ml samples of fresh manure from five Virginia dairy and five poultry farms were analyzed for total Kjeldahl, …

Effects of Feeding Phytase Enzyme and HAP Corn on Solubility of Phosphorus, Copper, and Zinc in Turkey Manure and Manure-Amended Soils
… instead of the NPA+P diet reduced total P in manures by 40%, but increased the percentage of total manure P extracted with 0.01 M CaCl₂ from fresh excreta (P < 0.05). Soils amended with wet NPA+Phyt, HAP, and HAP+Phyt manures released 29 to 49% more water-soluble P than soils amended with …

Economic Impact Analysis of Mixed-Species Green Manure on Organic Tomato: Evidence from the Northeastern United States
… about the benefits of using mixed species green manures were significant factors. Each variables and factors except age had a positive influence. Similarly, probit results for microbial inoculants indicated that education, gender, and access to the internet were significant determinants, and had …

Organic manure effects on selected soil properties, water use efficiency and grain yield of sunflower
The application of organic manures as alternatives to reduce the use of mineral fertilizers is considered a good agricultural practice for smallholder farmers. However, the effect of organic manure on soil properties and crop yield depends upon its application rate and chemical composition. …

Response of corn to high levels of CuSO₄ and ZnSO₄ applications
… to soils not only as a fertilizer but also as manures, pesticides and waste materials such as sewage sludge. High levels of Cu and Zn application to agricultural soils are considered to pose a potential hazard to plants and animals. Research findings have not established Cu and Zn levels that …

The Comparative Risk of Antimicrobial Resistance Transfer from Pig, Poultry and Bovine Manure to Grassland
… and Pseudomonas aeruginosa isolated from the manures and grassland were assessed and the molecular mechanisms of their resistance were investigated using PCR and whole genome sequencing (WGS). The manures, soil and the grass phyllosphere, both pre and post manuring, contained a diverse range …

Nitrogen dynamics and biological response to dairy manure application
Animal manures are land applied in agronomic systems to supply essential crop nutrients and decrease dependency on chemical fertilizers. Liquid manures are traditionally surface broadcast to fields and sometimes incorporated to reduce odor and nutrient losses; however, incorporation is incompatible …

Land, Labor, and Reform: Hill Carter, Slavery, and Agricultural Improvement at Shirley Plantation, 1816-1866
… lands, and employed a variety of fertilizers and manures to resuscitate his soils. Significantly, Carter efforts to improve Shirley transformed not only the physical landscape of the plantation. The changes produced in the work and lives of his slaves also were considerable. This study, then, …

The recovery and behavior of fertilizer nutrients from the anaerobic digestion of poultry manure
Nutrients of animal manures digested anaerobically for biogas production are highly conserved. The objectives of this study are to evaluate changes in the fertilizer value of poultry manure following digestion. Total kjeldahl N (TKN) was completely recovered during digestion, however, NH₄⁺N was 159 …

Nitrous oxide and methane emissions from agriculture and approaches to mitigate greenhouse gas emissions from livestock production
… GHG emissions from litter-based farmyard manures; evaluate means by which GHG emissions from agricultural production may be abated; assess synergies and conflicts between the abatement of other N pollutants on emissions of nitrous oxide (N2O); analyse two records of soil temperature from …
