Changes in Soil Properties, Organic Carbon, and Nutrient Stocks After Land‐Use Change From Forests to Grasslands in Kumaun Himalaya, India

Land Degradation and Development, Journal Year: 2025, Volume and Issue: unknown

ABSTRACT Land‐use changes are anticipated to be a substantial contributor global change climate, substantially causing significant modifications in soil characteristics. This study addressed the impact of land‐use from native forests grasslands on physico‐chemical properties entirely replicated three different forest zones (Oak, Pine and Cypress) temperate region Kumaun Himalaya. A total 162 samples (6 sites × 3 plots seasons depths = samples) were randomly collected each site triplicates depths. The texture, bulk density (bD), porosity, water holding capacity, moisture content, pH, organic carbon (SOC), nitrogen (TN), available phosphorus (P) potassium (K) determined at grassland sites. Results showed that bD, SOC, TN, P K significantly ( p < 0.05) decreased with increasing depth. Moreover, conversion into reduced nutrient concentrations, physical qualities (bD porosity), pH levels. decreasing trend along depth explains zone accumulation is not well established these because leaching effect. Our findings indicate natural resulted losses SOC TN stocks which can attributed disturbance forests. Therefore, while making plans, alterations nutrients must considered. These emphasize value establishing vegetation (forests) areas retain safeguard against runoff erosion. However, anticipating impacts alteration necessitates better comprehension its relations other drivers change, such as changing climate deposition.

Leguminous green manure intercropping changes the soil microbial community and increases soil nutrients and key quality components of tea leaves

Abstract Intercropping, a green and sustainable planting pattern, has demonstrated positive effects on plant growth the soil environment. However, there is currently little research influence of intercropping leguminous plants using them as manure environment tea quality. During profuse flowering period Chinese milkvetch, contents amino acids soluble sugar in with soybean increased by 6.89 54.58%. Moreover, was 27.42% increase ammonium nitrogen 21.63% available nitrogen. When milkvetch returned to for 1 month during its period, enhanced 9.11 33.96%, nitrogen, nitrate 25.04, 77.84, 48.90%. Intercropping systems also have quality components, fertility, microbial communities soybeans when this were field month. Furthermore, fertility index significantly increased, especially system tea–soybean–Chinese milkvetch. The bacterial community complexity fungal interactions increased. Soil pH, phosphorus found be crucial influencing factors communities, specifically communities. These results highlight significance optimizing improve components. They provide theoretical foundation promoting development plantations.

Effects of Different Types of Microplastics on Cold Seep Microbial Diversity and Function

Environmental Science & Technology, Journal Year: 2025, Volume and Issue: 59(2), P. 1322 - 1333

Published: Jan. 7, 2025

The massive production and widespread use of plastics have resulted in a growing marine plastic pollution problem. Cold seep ecosystems are maintained by microorganisms related to nitrogen carbon cycling that occur deep-sea areas, where cold hydrocarbon-rich water seeps from the ocean floor. Little is known about this ecosystem. To fill knowledge gap, we collected sediment seawater samples Haima conducted laboratory cultivation experiments, simulating situ environmental conditions. Environmental factors microbial genetics were analyzed at different stages over 2-month period. Our main conclusions as follows: (1) When microplastics (MPs) added environments, communities most closely resembled those original habitat. changes plastisphere mainly associated with culture time. (2) co-occurrence network was more fragile than environments. (3) Multiple determined community composition, whereas small number variables drove function. MPs affected methane metabolism might aggregate pathogenic species. This work provides better perspective effect on structure function seeps.

ABSTRACT Soil microbial diversity and community life strategies are crucial for nutrient cycling during vegetation restoration. Although the changes in topsoil communities restoration have been extensively studied, structure, strategies, function of subsoil remain poorly understood, especially regarding their role In this study, we conducted a comprehensive investigation soil community, assembly process, functional genes profiles (0–100 cm) across 36 year chronosequence (5, 15, 28, years) fenced grassland one grazing on Loess Plateau China. Our results revealed that organic carbon increased by 76.0% 91.6% after years The bacterial were influenced primarily depth, while fungal highly sensitive to Microbes recovered faster, structure gradually became more consistent following addition, observed transition history from persistent K -strategy rapid r Notably, process played an important genes, which accompanied fixation nitrogen mineralization function. Overall, our findings provide several novel insights into impact profile IMPORTANCE study microbes faster than those topsoil, contributed reduction differences distribution throughout process. Importantly, plays pivotal driving such as mineralization, alongside degradation gene abundance. These alterations increase availability understanding critical facilitate accumulation This insight can guide development manipulating nutrients grasslands.
