Evaluation of Specific Gravity and Electrical Conductivity for Determining Nutrient Concentrations in Suspensions of Poultry Manure
نویسندگان
چکیده
With increasing concern for the pollution potential of farm wastes, there is a corresponding need for rapid and robust methods of analysis for animal manures. In order to study the rapid testing methods based on the relationship between nutrient concentrations and physicochemical properties, diverse samples (n=105) were used in this study. The results indicated strong linear relations between specific gravity (Sg) and total phosphorous (TP), total nitrogen (Tn), volatile solids (VS), copper (Cu), iron (Fe), zinc (zn), and magnesium (Mg) concentrations (R2=0.80, 0.90, 0.91, 0.68, 0.71, 0.66, 0.77, respectively). Relationships between electrical conductivity (EC) and Sodium (na), ammonium nitrogen (an), and total potassium (TK) were significant with R2 values of 0.62, 0.85 and 0.68. Therefore, the hydrometer and conductivity meter can estimate rapidly nutrient concentrations of layer manure.

In the present paper Electrical Conductivity (EC) of Colloidal Gas Aphron (CGA) suspensions was measured for anionic and cationic surfactants (Sodium Dodecyl Sulfate (SDS) and Tetradecyl Trimethyl Ammonium Bromide (TTAB)). Experiments were made for different concentrations of SDS (6, 8.1, 10 mM) and TTAB (2, 3.51, 5 mM). CGA drainage behavior was observed and measured using 1 liter measuri...

Due to rapid expansion in the poultry industry, production of poultry manure has also consequently increased, resulting in unplanned disposal of this manure to the soil in some cases, with possible negative environmental consequences. In this study, 10 separate poultry manure samples were collected from different sites located in the central Eastern Cape, South Africa and characterized for chem...

Three manure agitation procedures were examined in this study (vertical mixing, horizontal mixing, and no mixing) to determine the efficacy of producing a representative manure sample. The total solids content for manure from gestation pigs was found to be well correlated with the total nitrogen (TN) and total phosphorus (TP) concentrations in the manure, with highly significant correlation coe...
