Transactions of the ASAE. American Society of Agricultural Engineers (T ASABE)
Transactions of the ASAE, an international journal published by the American Society of Agricultural Engineers, contains peer-reviewed technical articles on the current research being conducted to help solve problems in agriculture, food and other biological systems. Every technological advancement necessarily begins with research, and Transactions of the ASAE presents cutting-edge research on a broad range of topics including agricultural machinery, drainage, irrigation, electronics, biological engineering, forestry, food engineering, agricultural structures, crop production, natural resources, soils, and more. To qualify for publication, the material must represent original, important contributions to the research or design literature and meet other rigorous criteria during the peer-review process. The journal also serves as an information network, providing names and addresses of the people and organizations conducting research in these and related areas of interest.

In aseptic processing, packaging is done after the heat transfer steps, so product quality as well as packaging size and material options are generally improved. The objective of this study was to compare aseptic processing and conventional canning based on textural quality of apple slices. Aseptic processing of apple slices heated by direct steam contact was investigated in this study, and heat penetration testing was used to determine processing time by measuring the time required for the center of apple slices to consistently reach the setpoint temperature of 82.2� C. In canning, can center temperature was tested for the same conditions. Samples of Golden Delicious, cored, sliced, and unpeeled apple slices were taken from a commercial processing line and aseptically processed based on the processing time determined by heat penetration testing. The remainder of the apple slice population was commercially canned. The texture of the aseptically processed and canned apple slices was compared by measuring the peak shear force using a Kramer shear device. Compared to the texture of conventionally canned apple slices, aseptic processing improved the texture of apple slices by 57.4%, 31%, and 30.5%, respectively, for the three processing days. Aseptically processed apple slices consistently required a higher shear force than conventionally canned slices, indicating that the former were of higher quality.

A method to reduce the phosphorus content of dairy lagoon effluent is needed to allow continued effluent application for nitrogen and irrigation water without exceeding the phosphorus needs of the crop. This study examined the feasibility of using electric arc furnace (EAF) steel slag to remove dissolved reactive phosphorus from dairy lagoon effluent. Treatment columns filled with EAF steel slag had dairy lagoon effluent added with a 12 h retention time batch flow over a course of 106 days. Samples were collected weekly and analyzed for dissolved reactive phosphorus and pH. Differences between the influent and effluent for each treatment column were determined. Four treatments were compared: warm temperatures, cold temperatures, high organic content, and a gravel control. Significant differences were observed among treatments. Cold temperature resulted in the greatest phosphorus removal efficiency, followed by high organic content, warm temperature, and the gravel control. Among the EAF steel slag treatments, the average overall phosphorus removal efficiency for the 106-day study ranged from 63% to 71%. © 2011 American Society of Agricultural and Biological Engineers.

Few studies have been published that include monitoring data from construction sites, particularly highway construction sites. In this study, water quality monitoring of runoff originating from three sections of a highway construction corridor was conducted during a 4.5-year period. Two unnamed tributaries, referred to as Tilly and Ellery for this study, were monitored at two locations downstream of the highway corridor, and one tributary, referred to as King's Mill, was monitored upstream and downstream of the highway corridor. At each station, discharge was continuously monitored and flow-proportional samples were collected. Samples were analyzed for total suspended solids, total solids, and turbidity. A recording raingauge was also maintained at one of the highway monitoring stations. Monitoring data at all stations documented increased sediment export and turbidity levels during the construction period as compared to the pre- and post-construction periods. During construction, sediment export rates ranged from 2.7 to 17.7 Mg ha -1 year -1, while mean turbidity levels ranged from 466 to 1,607 NTU for the five stations downstream of the highway corridor. For the station with the greatest sediment export, about 32% of the export occurred during two back-to-back tropical storms. At this time, one section of the highway was particularly susceptible to erosion because more than 6 m of fill material had recently been added to bring the road surface to near grade and vegetation had not yet been established. Increases in sediment export and turbidity at the other four downstream stations during highway construction were less pronounced. Mean turbidity levels during construction at all downstream stations were greater than 50 NTU. Post-construction mean turbidity levels were much less than during construction but were still greater than pre-construction at four of the five stations. Post-construction turbidity levels on the King's Mill tributary downstream of the highway were not significantly different from upstream. © 2011 American Society of Agricultural and Biological Engineers.

Because of vegetation diversity and site-specific conditions, each species has its special pattern in the development of root systems. Therefore, there is a desire to provide an appropriate technique that can be adapted to different species. In this study, a penetrometer with minor modification is proposed for the pull-out test. In addition, two types of clamps were designed. To assess the feasibility in the field, four species were tested: maize (Zea mays L.), sunflower (Helianthus annuus L.), sugar beet (Beta vulgaris L) and fat-hen (Chenopodium album). Furthermore, two indices were verified: the peak value of pull-out force, and the work of a complete pull-out course. The statistical results showed that both the shoot heights and stem diameters of maize and sunflower (single-branched plants) were significantly correlated with the peak value of pull-out force (0.871 ≥ R 2 ≥ 0.798). Alternatively, the work of the pull-out course was suitable for fat-hen (multi-branched plant) in relation to the root dry mass (R 2 = 0.791). For sugar beet, a weak correlation (R 2 = 0.371) was observed, and the reason is interpreted. In addition, the failure rate of uprooting each species by each clamp is presented. In general, the proposed technique could be regarded as an effective tool in ecological and agricultural investigations. © 2011 American Society of Agricultural and Biological Engineers.
