Soil health assessments within managed agroecosystems help to further understand conservation practice efficacy when management practices are altered. In this study, soil was quantified via the Management Assessment Framework (SMAF) and Haney Health Test (HSHT) eight fields (a dryland pasture seven under no-till conditions for various time lengths, cropping system diversity differences, (in)organic fertilizer use) in Northeastern Colorado. The results across systems were variable comparing two frameworks, yet site received greatest score (SHS) from both frameworks. differences present physical, chemical, biological indicators SMAF, HSHT outcomes show high variability between each field, SHS did not align with understanding of practices. SHSs greatly relied on single indicator Solvita CO2-C burst (r = 0.82). mineralizable N overestimated availability correlated SMAF 28-day mineralization (R2 < 0.01), a pathway analysis, only (β-glucosidase (BG) microbial biomass carbon (MBC)) along bulk density (Bd) HSHT. overall scores frameworks moderately 0.48), which ascribed lack physical chemical indicators. While can still be useful tracking general trends over time, remains more comprehensive robust tool assessing studied agroecosystems.

Impact of Three Decades of Conservation Management Systems on Carbon Management Index and Aggregate Stability

Sustainability, Journal Year: 2025, Volume and Issue: 17(8), P. 3378 - 3378

Published: April 10, 2025

The sustainability of agroecosystems depends on the maintenance soil organic matter (SOM) and aggregate stability, which are key components health. long-term effects conservation management systems, such as adoption no till (NT) associated with cover crops, quality still unclear. aim this study was to evaluate NT systems combined cropping ecologically intensified by presence legumes carbon index (CMI) state aggregation, sensitive tools assess systems. autumn spring legume crops increased proportion aggregates > 2 mm, resulting in higher weighted average diameters aggregation values comparison conventional tillage (CT), favored microaggregate proportion. C content only surface layer, while use stock 23% compared system without 0–20 cm layer. In topsoil under NT, stocks particulate (POM) mineral-associated (MAOM) were 100% 37% greater than CT, respectively. A CMI observed CT (18%), one (52%), two (72%) crops. These results highlight till’s positive impact health, further enhanced legume-based ecological intensification

Biochar Derived from Agro-Industrial Waste: Applications in Agricultural and Environmental Applications

Agronomy, Journal Year: 2025, Volume and Issue: 15(5), P. 1087 - 1087

Published: April 29, 2025

The aim of this study was to investigate in vegetation and laboratory experiments the impact biochars derived from agro-food industry waste (wheat bran cherry pits) on selected soil chemical properties, maize yield, composition, as well their ability adsorb zinc copper, thereby reducing uptake by plants. obtained results indicate that produced under same pyrolysis conditions differ composition. Both significantly increased total organic carbon (TOC) nitrogen (TN) content soil, but they did not affect availability nutrients soil. tested enhance plant yields or increase N, P, K, Mg, Ca However, both reduced Zn Cu plants due adsorption these elements biochars. experiment biochar wheat adsorbed approximately 438.5 mM(+) kg−1 566.8 kg−1, while pits 239.4 303.5 solution. ion exchange contribution Zn2+ Cu2+ 65.8% 65.0%, respectively. In contrast, for pits, contributions were 59.4% 44.7%,
