Soil organic carbon (C) and aggregates are the important components of soil fertility foundation sustainable agriculture. The storage protection SOC in is widely regarded as material basis C accumulation. However, current understanding aggregate its associated insufficient to elucidate regulation mechanism C. A nine-year field experiment including chemical fertilizer (FR) manure (OM) treatments was set up eastern plain Funiu Mountain, central China. Using analysis, physical sieving well...
This paper was primarily devoted to understand the interactions of soil aggregates, organic carbon (C) and cycle enzymes in aggregates under different fertilization managements, aiming identify effects inorganic fertilizer amendments on C accumulation activities within Vertisol.A Vertisol following 4-year compost amendments, i.e. no (CK), mineral (FR) 60% N plus 40% (FRM), collected dynamics C, their associations with macroaggregation using aggregate fractionation techniques.The content all...
The input of exogenous organic materials is an effective way to improve soil matter (SOM) content in cropland. exploration the impact new such as woody peat on black fertility can provide important reference for preventing degradation Northeast China. In this study, effects adding SOM and soil-integrated cropland were studied by seven treatments (no addition, CK; crop straw returning, SR; decomposed DS; manure OM; 6 t/ha LWP; 10.5 natural humus material MWP; 15 HWP). results show that...
The overapplication of mineral nitrogen (N) fertilizer has become a scientific problem to be solved in the North China Plain; meanwhile, most organic manure cannot recycled into soil. To make full use and decrease applied rate N fertilizer, four-year fertilization experiment was carried out assess effects substituting with on soil carbon (SOC), labile (LOC), stable (UOC), microbial biomass (MBC), enzymatic activity. There were six treatments including unfertilized control (CK); without (FR);...
A 5-year (2012-2016) field experiment was conducted to investigate the impacts of different fertilizer treatments (no fertilizer, mineral and organic fertilizer) on carbon soil water-stable aggregates in a North China Plain Vertisol. Compared with no (control), single did not significantly (P < 0.01) affect content or aggregate mass proportion bulk soil. Small large macroaggregate proportions increased, but applying manure decreased silt + clay fraction microaggregates. Organic amendment...
Soil aggregates are the core physically distinct units that embedded in complex soil matrix. The roles of saprophytic fungi aggregation and their relevant mechanism is not fully understood. Here, a microcosm was conducted to study two on aggregation. plant growth promoting Mortierella (K1) Chaetomium (F1) were selected as representative species. After original destroyed using 100 mesh sieve, sterilized placed petri dish, fungal strains inoculated after sterile water added bring 60 % maximum...
Abstract Agricultural soil organic carbon (SOC) plays a critical role in ecosystems, and SOC sequestration is key ecosystem service. This study investigated the fractions, including mineral‐incorporated (MSC), intra‐particulate (iPOC) microbial biomass (MBC), bulk water‐stable aggregates, as influenced by fertilization managements, using three treatments: no fertilizer (CK), chemical (FR) manure (OM). Fertilizer application significantly increased content its fractions (MSC, iPOC MBC)...
Abstract Straw return with nitrogen (N) fertilizer can generally regulate soil N cycling by affecting the microbial community, thereby influencing crop productivity. Bacteria and fungi play a key role in nitrification, while effects of interactions that include protists under condition straw remain uncertain. Here, we evaluated importance microbiome, particularly ammonia‐oxidizing bacteria (AOB), regulating transformation potential wheat yields different fertilization practices. The results...
Core Ideas Changes in SOC over 30 yr were revealed a field survey Henan Province of China. We analyzed influential factors spatiotemporal variability at large scale. Cropland was shown to have great potential for C sequestration the future. Spatial and are important evaluate soil organic (SOC) pool areas. In present study, sampling conducted from May November 2011 Province, typical agricultural region Central China, study effects properties anthropogenic on cropland. Physicochemical samples...
Core Ideas Manure improved soil aggregate‐associated C and N sequestration. Fertilizer substituted with manure in increasing concentrations used. water stable aggregate stability. management influences the accumulation of organic agricultural soils. The combined use chemical fertilizers is considered a good method to enhance fertility, but it still unclear about effects substituting for fertilizer on aggregation associated N. We selected 4‐yr‐old fertility experiment examine response...
Ammonia oxidizing archaea (AOA) and ammonia bacteria (AOB) have been proven to be key microorganisms driving the oxidation process. However, under different fertilization practices, there is a lack of research on impact interaction between predators AOA or AOB nitrogen cycling at multi-trophic level.
The accurate estimation of the soil organic carbon (SOC) sequestration rate is very important for studying farmland fertility and environmental effects. In this research, a typical fluvor-aquic area, Fengqiu county, located in Yellow River basin Huang-Huai-Hai Plain China, was chosen as study area. physicochemical properties 70 samples collected from surface layer (at depth 0–20 cm) 2011 were analyzed, related data about sampling sites also Second State Soil Survey China (SSSSC), conducted...
