A zoning-based machine learning framework for accurate soil organic matter prediction across Mollisol and non-Mollisol regions

Journal of Integrative Agriculture
Soil organic matter (SOM) is a core indicator of soil fertility and ecosystem function. However, in regions where Mollisol and non-Mollisol coexist, high-precision spatial mapping faces significant challenges due to pronounced terrain heterogeneity and ...

Distinct effects of short-term reconstructed topsoil on soya bean and corn rhizosphere bacterial abundance and communities in Chinese Mollisol [PDF]

Royal Society Open Science, 2019
Eroded black soils (classified as Mollisols) lead to a thinner topsoil layer, reduced organic carbon storage and declined crop productivity. Understanding the changes in soil microbial communities owing to soil erosion is of vital importance as soil ...

Distribution of earthworm growth stages along a naturally occurring soil salinity gradient

Soil Organisms, 2021
One major soil health challenge of the Northern Great Plains of North America is the natural occurrence of soluble salts in the soil. Salinity impacts on plant production are well understood, but we stand to learn more about the effects of salinity on ...

Variation of soil organic matter depends on light-fraction organic matter under long-term monocropping of different crops

Plant, Soil and Environment, 2021
Cultivating crops influences soil organic matter (SOM), but the effect of different crops remains unclear, particularly under long-term monocropping.

Organic carbon in Mollisols of the world – a review

1st International Conference of Soil and Agriculture TOWARDS SOIL SUSTAINABILITY/9788372594570, 2023
Mollisols represent 29 % of agricultural land and they are considered to be one of the most fertile soils in the world. Here, we compare soil organic carbon (SOC) concentrations and pools of Mollisols for the globe, the USA and Poland, and review how differences are caused by climate, land use, and key environmental factors.

Quantifying Phosphorus Leaching Loss from Mollisol with Organic Amendments

Agronomy, 2022
The phosphorus (P) leaching from continuous fertilization is generally neglected in mollisol. The in situ leaching loss of phosphorus (P), especially dissolved organic P, is poorly quantified under organic amendments given its potential environmental ...

Soil type-dependent effects of drying-wetting sequences on aggregates and their associated OC and N

International Soil and Water Conservation Research, 2022
Evaluating the impacts of drying-wetting (DW) cycles on soil aggregates and their associated organic carbon (OC) and nitrogen (N) is crucial to understand the OC and N cycles.

Long-term effect of fertilization and manuring on soil aggregate carbon mineralization

The Indian Journal of Agricultural Sciences, 2021
The 32 years impact of manuring and fertilization on carbon mineralization in macro- and micro-aggregates in major soil groups of India was studied.

The Lower Boundary of Selected Mollisols [PDF]

Soil Science Society of America Journal, 1967
Abstract Thicknesses of three Mollisols (Tama, Elburn, and Drummer series), developed from Wisconsinan‐age material in a toposequence in Central Illinois, were considerably greater (18 to 68 cm) when their lower boundaries were determined by the depth of rooting of native perennial big bluestem (

Soybean yield and yield component distribution across the main axis in response to light enrichment and shading under different densities

Plant, Soil and Environment, 2010
A 2-year field experiment was conducted under light enrichment and shading conditions to examine the responses of seed yield and yield components distribution across main axis in soybean.
