Physical and thermal characteristics of dairy cattle manure.

摘要: Greenhouse and regulated gas emissions from animal waste are naturally mediated by moisture content temperature. As with soils, manure could be readily estimated given the physical, hydraulic, thermal properties described models microbes nutrients not limiting factors. The objectives of this study were to measure model dairy support advanced modeling water fluxes in addition solute, colloid, heat transport. A series soil science measurement techniques applied determine a set fundamental as-excreted cattle manure. Relationships between dielectric permittivity volumetric (θᵥ) obtained using time-domain reflectometry capacitance-based measurements. measured retention characteristic for was similar organic peat soil. unsaturated hydraulic conductivity function inferred inverse numerical fitting laboratory evaporation results. manure, including conductivity, diffusivity, bulk capacity, also determined three penta-needle pulse probes. accuracy capacity measurements comparison theoretical θᵥ, that measurement. These data represent novel unique contribution advancing prediction capabilities although uncertainties associated complexities shrinkage, surface crust formation, cracking must considered.
