Comparación del carbono orgánico proveniente de los ácidos húmicos, ácidos fúlvicos y el grado de humificación en cinco órdenes de suelos

open access: yesPeruvian Journal of Agronomy, 2021
En este estudio se realizaron las comparaciones del contenido de carbono orgánico (CO) en las fracciones de los ácidos húmicos (AH) y los ácidos fúlvicos (AF) en cinco órdenes de suelos (Aridisol, Entisol, Histosol, Inceptisol y Mollisol) y conocer su ...

Soil degradation: a problem threatening the sustainable development of agriculture in Northeast China

open access: yesPlant, Soil and Environment, 2010
Soil degradation that results from erosion, losses of organic matter and nutrients, or soil compaction are of great concern in every agricultural region of the world. The control of soil erosion and loss of organic matter has been proposed as critical to

Exclusion of plant input affects the temperature sensitivity of soil organic carbon decomposition

open access: yesEcological Indicators, 2022
Plant residue input plays a vital role in cropland carbon (C) balance, which can be greatly affected by climate change. Our knowledge of the effect of plant residue on soil respiration is crucial for evaluating C exchange between the atmosphere and ...

Levantamiento de suelos en la cuenca baja del río Pilón, Nuevo León, México

open access: yesInvestigaciones Geográficas, 1993
A soil survey was carried out at a semidetailed level by means of aerial photography and the relationships of photographic–soil and landscape–soil images. This permitted to separate the photointerpretation units.

Ditch‐Buried Straw Return Improves Soil Physical Quality and Crop Biomass in Two Rice–Wheat Paddy Soil Systems

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Ditch‐buried straw return (DB) is an innovative practice combining deep tillage and straw incorporation. This study aimed to evaluate its effects on soil physical quality compared to rotary tillage (RT) and identified key constraints to crop in sandy‐loam and clay‐loam paddy soils within rice–wheat systems. Two field experiments were conducted

Effects of Straw Incorporation and Tillage Depth on Soil Quality in Mollisol Profiles

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Although improvements in soil quality under straw incorporation have been well documented, responses across soil profiles under different tillage depths remain unclear. To address this issue, a field experiment was established in 2011 in Mollisols with conventional tillage (20 cm depth) without straw (CT) and with straw (SCT), no tillage with ...

Knowledge gap on the spatial structure of soil nitrogen mineralization variability—A systematic review

open access: yesAgricultural &Environmental Letters, Volume 11, Issue 2, December 2026.
Abstract Soil nitrogen (N) mineralization governs plant‐available N from soil organic matter and microbial turnover, and is typically estimated as potentially mineralizable nitrogen (PMN) via anaerobic incubations or as N0 and mineralization rate (k) via long‐term aerobic incubations.
