0016-7061
Subject:
case studies; prediction; sample size; sand fraction; soil organic matter; soil surveys; China
Abstract:
... Sampling design plays a key role in digital soil mapping (DSM). Efficient sampling design for multiple soil properties is increasingly needed for multivariate soil survey and mapping. However, most of the present sampling methods are not developed for multiple soil properties. Different soil properties have different influential covariates, but usually only one set of covariates is used in designi ...

Abstract:
... Interminable plant production with negligent management might lead to zinc (Zn) depletion in soils, which could induce a Zn deficit in staple foods and cause human Zn malnutrition in many of the least-developed countries. Knowledge of the Zn pool and balance in soil-cassava systems is unclear and requires a detailed investigation. Herein, we examined Zn mass inputs (weathering and manure) and outp ...

Abstract:
... Increasing carbon input (CI) to soil has been widely recommended (e.g., residue retention and manure application) to sequester more carbon in agricultural soils thereby mitigating climate change and improving soil quality. However, carbon sequestration may not respond linearly to additional CI due to their active interactions with the turnover of native soil organic carbon (SOC) via such as the pr ...

The adoption of Urochloa forages (formerly known as Brachiaria) with biological nitrification inhibition (BNI) capacity is a promising alternative to reduce nitrous oxide (N₂O) emissions from excreta patches. However, how this forage affects methane (CH₄) or carbon dioxide (CO₂) e ...

Abstract:
... High-quality plant inputs to the soil with low lignin to nitrogen ratios have been conceptualized to foster the formation of soil organic matter (SOM) and carbon (C) in stabilized soil compartments, such as aggregates and organo-mineral associations (MAOM), in dependence of the soil’s capacity to store additional C (i.e., C saturation deficit). Yet, evidence for these conceptualizations from field ...
