Published: March 17, 2025

Background The objective of this study was to determine the optimal level molasses required for ensiling seed-used zucchini peel residue and corn stalks mixtures, using a 2:1 ratio stalks. experiment included control group (CON, with no added), 1% (M1, 10 g kg −1 fresh matter), 2% (M2, 20 3% (M3, 30 matter). After 60 days fermentation, samples silage were collected analyzed their chemical composition, fermentation quality, aerobic stability, ruminal degradation characteristics. Result Compared CON group, addition significantly decreased both pH ammonia nitrogen total (NH3-N/TN) in ensilage mixture In molasses-treated groups, values by 0.08, 0.09, 0.13, respectively, compared group. NH3-N/TN ratios 1.52, 1.86, 2.24, Additionally, contents neutral detergent fiber (NDF) acid (ADF) lower than those However, reduced stability feed, molasses-added showing significant decrease stability. Furthermore, improved rates silage, M3 dry matter (DM), crude protein (CP), ADF at 65.49, 55.26, 46.18%, respectively. Conclusion is beneficial improving quality stalks, nutritional components increasing rate.

Risk preference, government regulation, and the sustainability of crop straw resource utilization—based on research data from Liaoning Province, China

Frontiers in Environmental Science, Journal Year: 2025, Volume and Issue: 13

Published: April 28, 2025

Introduction Global crop straw production has increased sharply, leading to serious challenges in burning and disposal. The unsustainable practice of open wastes valuable renewable resources poses significant environmental threats, such as air pollution soil degradation, that undermine global agricultural sustainability. Despite extensive efforts by the Chinese government promote resource utilization (CSRU), low farmer participation reliance on a singular technological structure remain persistent issues. Methods Drawing prospect theory, this study integrates behavioral economics policy analysis examine how farmers’ risk preferences, including aversion, loss nonlinear probability weighting, interact with heterogeneous regulations, incentives, restrictions, guidance, shape CSRU behavior. Using micro-survey data from 440 rural households Liaoning Province, China, we apply logit model quantify these relationships analyze moderating role specific measures. Results empirical results show farmers generally exhibit strong which increases average adoption 10.56%, meanwhile an excessive focus low‐probability risks significantly willingness. Furthermore, fiscal incentives direct subsidies effectively amplify positive effect increasing its marginal impact 23.7%. In contrast, relying solely regulatory measures tends weaken compliance costs, thereby reducing 5.22%. Additional reveals heterogeneity responses based income structures business models: high‐level part‐time much stronger response their aversion being approximately 3.5 times low-level part-time farmers. Discussion By synthesizing insights economics, elucidates mechanism through economic are balanced process highlights critical tools. findings provide evidence for optimizing management, formulating more cost-effective policies, promoting green transformation agriculture.

Characteristics and Changes in the Properties of Cereal and Rapeseed Straw Used as Energy Feedstock

Energies, Journal Year: 2024, Volume and Issue: 17(5), P. 1243 - 1243

Published: March 5, 2024

Solid biofuels, including straw as production residue, are still the largest energy feedstock in structure of primary from renewable sources. However, properties a solid biofuel can vary depending on species which it was produced and harvest period year. Therefore, this study aimed to assess thermophysical elemental composition six types (rye, oat, triticale, wheat, corn, rapeseed straw) obtained over three consecutive years (2020, 2021, 2022). Rye had lowest moisture (mean: 10.55%), ash 2.71% DM), nitrogen 0.54% DM) chlorine 0.046% contents highest carbon content 47.93% higher heating value—HHV 19.03 GJ Mg−1 lower value—LHV 15.71 Mg−1). Triticale similar properties, classifying into same cluster rye straw. Corn remarkably high 48.91%), low LHV content. Rapeseed contained levels Cl, S, N ash, they were 643%, 481%, 104% 169% higher, respectively, than those The sulfur, under highly variable during study. Knowledge different feedstocks facilitates logistics organization supply bioenergy installations. further research is needed, especially studies assessing intensity logistical costs used for purposes.

The current study deals with an examination of strategies for the sequential treatment corn stalks (CSs) in integrated manner aiming to obtain papermaking fibers and recover both lignin hemicelluloses (HCs). Several pathways valorization were experimentally trialed, focusing on getting information from mass balance analysis attempt reveal potential outcomes terms pulp yield, chemical composition, properties such as tensile burst strength. raw amounts purity well separated also characterized. In this work, yields range 44–50% obtained CSs, while yielded maximum values 10 g/100 g CS 6.2 CS, respectively. Other findings evidenced that besides pulp, HCs have interesting output values. recovered yield shown be less than 50% general, meaning even if 67 90% it is removed only about half recovered. removal rates found approx. 30 60%.

In recent years, biomass utilization has significantly increased, presenting challenges in its incorporation into various systems. Effective handling requires reliable data on flow properties for designing warehouses and processing equipment. This study investigates the physical of ground barley grains, oak leaves, straw, cut jute. Barley straw bales were milled, jute was 2–3 mm lengths oven-dried. Particle size distribution, bulk density, Hausner ratio, Carr’s index, moisture content, static angle repose, flowability tests SEM analysis conducted. The found that barley, having smallest particle highest showed superior due to rounded particles clusters, as reflected by a low ratio. contrast, fibers had density poor flowability, while exhibited hindered larger, more irregular particles. Additionally, sliding behavior varied with surface irregularities, adhering well plywood leaves aluminum. These findings underscore pivotal roles shape interparticle forces determining properties, pointing towards future where precise environmental control advanced analytical methods drive innovations utilization.
