Design and evaluation of a grain respiration measurement system for dry matter loss of soybeans
… was designed, fabricated and tested to estimate dry matter loss (DML) of soybeans through monitoring carbon dioxide (CO2) from grain respiration by gravimetric analysis. The system consisted of three parts: conditioned air input, grain respiration column, and moisture and carbon dioxide …

Dry matter loss and compositional analysis of large switchgrass round bales during ambient storage in Virginia
… weathered layer to the inner core, depending on drying conditions since the last precipitation. In one instance weathered layer moisture content was three times the core moisture content Netwrapped bales were drier than string-wrapped bales. Negligible dry matter loss (DML) was reported at four …

Dry matter loss and lipid oxidation evaluation of soybeans during storage at elevated moisture content and temperature
Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2023-08-01

Dry matter loss rates of soybeans: Effects of respiration measurement system, damage by splits, and moisture content at elevated temperatures
… on the final use of soybean, t_s can be based on dry matter loss (DML), germination, or mold growth. DML can be estimated by measuring the amount of respired carbon dioxide (CO2) during grain storage, and so has become the basis of previous recommendations for t_s of grains, oilseeds, and …

Evaluating dry matter loss rates of 14 to 22% moisture content soybeans at 35°C using a dynamic grain respiration measurement system
… respiration rate (v_(〖CO〗_2 )) and, thus, dry matter loss rate (v_DML) are affected by moisture content (w) and temperature (T). Knowledge of v_(〖CO〗_2 ) or v_DML is useful in developing maximum allowable storage time (MAST) guidelines for soybeans, which are currently sorely lacking for …

An Analysis Of The Impact Of Storage Temperature, Moisture Content & Duration Upon The Chemical Components & Bioprocessing Of Lignocellulosic Biomass
… Stored samples of each were examined for dry matter loss and composition change to develop a material balance around carbohydrates and lignin.</p> <p>A mean dry matter loss of 24% was observed at 8 weeks in sweet sorghum stored at high moisture content (26% w/w). Soluble sugars …

The effect of controlled atmospheres on the keeping quality of sweetpotatoes
… 1963-65 period. Evaluations were made of decay loss, weight and dry matter loss, soluble solids percent, carotene content, taste of raw and baked roots, keeping after storage, and the ability of roots to sprout. In 1963-64, ranges of carbon dioxide from 0 to 15 percent were used in combination …

Modelling the microclimate in a conical bottomed circular grain silo
… absolute humidity, wet bulb temperature, dry matter loss, seed viability and pesticide decay. Significantly, a novel configuration of an annular aeration duct and a traditional linear aeration duct in farm silos have been investigated. It was found that the annular aeration system provides …

Numerical model for analysis and control of the quality of bulk-stored grain using cold air
… can be slowed, seed viability is maintained, dry matter loss is reduced and the persistence of chemical pesticides can be improved. This thesis reports the development of a mathematical model of ventilated grain stores that enables optimal cooling strategies to be identified and developed. The …

Ensiling characteristics, digestibility and palatability of tropical grasses as affected by growth stage, chopping length and additives
… acetic acid of silage increased (P<.01), whereas dry matter loss and pH decreased (P<.05) with fineness of chop. In a third study, 2 and 3 wk growths of Guinea-'A' were harvested and ensiled in 210 liter metal drums, double lined with polyethylene bags, chopped or unchopped. Cutting grass at 2 wk …

Direct and Indirect Greenhouse Gas Emissions from Biomass Storage: Implications for Life Cycle Assessment of Biofuels
… biofuels do not sufficiently account for biomass losses and emissions associated with the harvest and storage of biomass feedstocks, which can require additional fuel and materials use on the farm as well as reducing the effective yield of a crop at the biorefinery gate. The goal of this …
