Novel Pilot Development Of A Closed-Loop Sustainable System Between Biogas Renewable Energy, Distilling, And Aquaculture By Vermiculture Of Stillage Wastes, Samuel C. Kessler Sep 2021

Novel Pilot Development Of A Closed-Loop Sustainable System Between Biogas Renewable Energy, Distilling, And Aquaculture By Vermiculture Of Stillage Wastes, Samuel C. Kessler

The Cardinal Edge

This study provides a mixed-methods approach in analyzing a potential closed-loop system between renewable biogas production from anaerobic digestion, vermiculture production, aquaculture production, and organic wastes with a particular focus on stillage wastes. Such system may hold significant promise for significantly reducing organic carbon and methane emissions from its components, and should be assessed for such. The 2021 IPCC report essentially identified methane reduction as the single fastest way to slow global warming (IPCC, 2021), making the study and implementation of methane-reducing systems and supportive policy for them critical. Knowledge gaps to implementing this system were qualitatively identified as disconnect …

Development Of Yam-Starch-Based Bioplastics With The Addition Of Chitosan And Clove Oil, Ulyarti Ulyarti, Lavlinesia Lavlinesia, Surhaini Surhaini, Nurainun Siregar, Anggel Tomara, Lisani Lisani, Nazarudin Nazarudin Jun 2021

Development Of Yam-Starch-Based Bioplastics With The Addition Of Chitosan And Clove Oil, Ulyarti Ulyarti, Lavlinesia Lavlinesia, Surhaini Surhaini, Nurainun Siregar, Anggel Tomara, Lisani Lisani, Nazarudin Nazarudin

Makara Journal of Science

The potency of yam starch (Dioscorea alata) as film-forming material together with the potency of chitosan and clove oil as antibacterial materials has led the authors to produce active bioplastics based on these materials. This research was performed to determine the effect of chitosan and clove oil on the physical, mechanical, and barrier properties of yam starch’s active bioplastics. The best bioplastics produced were further tested for their antimicrobiological properties. This study used a completely randomized design with five levels of chitosan concentration (1%, 1.2%, 1.4%, 1.6%, and 1.8%) and five levels of clove oil concentration (0.3%, 0.6%, …

Comparison Of Static And Active Downforce On Corn At The Kansas River Valley Experiment Field In 2020, E. A. Adee Jan 2021

Comparison Of Static And Active Downforce On Corn At The Kansas River Valley Experiment Field In 2020, E. A. Adee

Kansas Agricultural Experiment Station Research Reports

Uniformity of plant spacing and emergence have been shown to be significant contributing factors to increasing corn yields. Improved seed meters that offer very precise seed drop have been available on planters for a number of years. However, uniformity in plant emergence continues to be a challenge, especially with reduction of tillage and in fields with variable soils. Correct, consistent depth is critical for uniform corn emergence. By keeping the gauge wheels on the ground, consistent depth is achieved. An active downforce system, such as Precision Planting’s DeltaForce, applies hydraulic downforce or lift to the row unit. With a Precision …

Using A Sprayable Biodegradable Polymer To Reduce Soil Evaporation In Greenhouse Conditions, J. Flory, J. Grane, A. Patrignani Jan 2021

Using A Sprayable Biodegradable Polymer To Reduce Soil Evaporation In Greenhouse Conditions, J. Flory, J. Grane, A. Patrignani

Kansas Agricultural Experiment Station Research Reports

Sprayable biopolymer membranes (SBM) is an emerging mulching alternative to increase horticultural and agricultural productivity by reducing soil erosion and evapo­rative losses. The SBM is usually applied in liquid form directly to the soil surface where the polymer molecules form a thin biodegradable film. In order to test this technology, an experiment was performed in greenhouse conditions with the goal of quantifying the impact on soil evaporation rate and biomass accumulation in winter wheat.

Laboratory Calibration Of The Spectrum Field Scout Tdr 300, W. Dyer, D. Bremer, P. Rossini, M. Stone, A. Patrignani Jan 2021

Laboratory Calibration Of The Spectrum Field Scout Tdr 300, W. Dyer, D. Bremer, P. Rossini, M. Stone, A. Patrignani

Kansas Agricultural Experiment Station Research Reports

Soil moisture sensors (SMSs) are a useful tool that aid in data-driven water management decisions. However, default factory calibrations can be inaccurate and soil-specific calibrations are often required to obtain higher accuracy in the determination of soil water storage and plant available water. In this study, we conducted a lab calibration for the Field Scout TDR 300, which is a popular SMS used in the turfgrass industry. Five soils of different soil textural classes were packed in containers with known soil moisture for the laboratory calibration. The logarithmic model best fit the data for the course- and fine-textured soils, with …
