Nitrogen addition alters soil organic carbon (SOC) and total nitrogen (TN) accumulation in forest ecosystems, but the responses of SOC TN sequestration rates dynamics to ecosystems worldwide remain unclear. This study conducted a global analysis evaluate effects application rate, duration (time), humidity on from 257 data points (63 articles). increased by 4.48% 10.18%, respectively.

Soil Microbial Biomass and Bacterial Diversity Enhanced through Fallow Cover Cropping in Rice–Fish Coculture

Agronomy, Journal Year: 2024, Volume and Issue: 14(3), P. 456 - 456

Published: Feb. 25, 2024

Traditional rice production is often reliant on the unsustainable practice of utilizing intensive inputs in monoculture cropping systems. Alternatives fallow cover and rice–fish coculture (RFC) offer promising solutions. However, potential RFC remains underexplored, its impact soil microbes poorly understood. In this study, assessments soil–plant–microbe interactions were conducted across three systems: Chinese milk vetch (Astragalus sinicus L.) single (CM), Rapeseed (Brassica napus (RP), a combination rapeseed intercropping (CM_RP). These systems evaluated with without nitrogen (N) addition, encompassing both (RMC) The findings indicate notable increase microbial biomass (MBN) CM. Soil carbon (MBC), influenced more by N-fertilizer than crop species, decreased N addition. system, bacterial co-occurrence network exhibited connections, yet negative links increased.

Patterns and environmental drivers of C, N, and P stoichiometry in the leaf‐litter‐soil system associated with Mongolian pine forests

Ecology and Evolution, Journal Year: 2024, Volume and Issue: 14(3)

Published: March 1, 2024

Abstract Ecological stoichiometry is an important approach to understand plant nutrient cycling and balance in the forest ecosystem. However, understanding of stoichiometric patterns through leaf‐litter‐soil system Mongolian pine among different stand origins still scarce. Therefore, reveal variations carbon (C), nitrogen (N), phosphorus (P) homeostasis origins, we measured C, N, P concentrations leaves, litter, soil, analyzed resorption efficiencies leaves differently aged plantations natural forests from semi‐arid dry sub‐humid regions. The results showed that (1) origin had a significant effect on C–N–P stoichiometry, also significantly affected leaf N reabsorption efficiencies. Leaf N/P ratios indicated was co‐limited by NF, HB HQ, mainly limited MU. (2) With increasing age, C initially increased then decreased, were gradually increased.
