متن کاملChallenges in measuring moisture content of feeds.
Accurate determination of the moisture (water) content in individual feed ingredients and mixed feeds is critical throughout the feed industry. Most analytical methods used to determine apparent water content of feedstuffs are empirical, estimating water by evaporation and loss of weight on drying (oven drying methods). These methods differ greatly in effectiveness, resulting in bias. Bias asso...
متن کاملUsing cereal grain permittivity for sensing moisture content
A brief history of cereal grain moisture measurement by sensing the electrical properties of grain is presented. The basic principles are also described for using radio-frequency (RF) and microwave dielectric properties, or permittivity, of grain for sensing moisture through their correlation with moisture content. The development of density-independent functions of the permittivity is explaine...
متن کاملEvaluation and Calibration of a Soil Moisture Sensor for Measuring Poultry Manure or Litter Moisture Content
Moisture content (MC) of poultry manure or litter affects its ammonia (NH 3 ) emissions. Relating MC to ammonia emission of manure or litter is thus of importance to modeling and/or managing ammonia emissions from the manure sources. Development of such relationships would require the knowledge of ammonia emission and the concomitant MC of the manure or litter. This work was carried out to char...
متن کاملInvestigating the Effect of Soil Organic Matter on Gypsum Block Calibration for Measuring Soil Volumetric Moisture Content
Continuous soil moisture assessment and evaluation is essential for irrigation management and planning. One of the common methods for measuring the moisture content of the soil is the use of a gypsum block. The use of gypsum blocks in some cases, including the presence of organic matter in soil, may cause an error in the measurement of moisture. For this purpose, a laboratory study was conducte...
