Topographic and Climatic Determinants of Soil Organic Carbon Across Landscapes: A Meta‐Analysis

Land Degradation &Development, EarlyView.
ABSTRACT The soil is the greatest natural store of organic carbon, holding between 1500 to 1550 Pg C of organic carbon at the top 100 cm of the soil globally—roughly twice the carbon pool in the atmosphere. The spatial distribution of this stock is controlled by a complex chain of controls: topographic position regulates the hydrological redistribution,

Amélioration de la croissance et des paramètres agronomiques du maïs (Zea mays L.) par des composts de déchets dans la carrière des calcaires de Sika-Kondji au Sud-Togo

Revue Marocaine des Sciences Agronomiques et Vétérinaires, 2017
Mineral resources exploitation is one of the main causes of soil degradation and pollution. Restoration of mines after exploitation is a priority of mining companies.

Spatial Patterns, Driving Forces, and Potential Grain Losses of Non‐Grain Production of Farmland in Central Yunnan Urban Agglomeration, China

Land Degradation &Development, EarlyView.
ABSTRACT The expansion of farmland non‐grain production (NGP) poses a potential threat to food security and agricultural land protection, particularly in mountainous urban agglomerations. However, the utilization patterns, driving mechanisms, and associated production‐loss effects of farmland NGP in this specific regional context remain insufficiently ...

Mechanism of Combined Improvement of Saline‐Alkali Soil by Artificial Humic Acid and Microbial Inoculant

Land Degradation &Development, EarlyView.
ABSTRACT To address the widespread constraints imposed by saline‐alkaline soils on agricultural production worldwide, the combined reclamation and carbon cycle regulation effects of artificial humic acid (AHA) and a multifunctional microbial inoculant were evaluated through pot experiments. Results demonstrated that co‐application of AHA (4 g·kg−1) and

Improving Soil Health and Crop Yields Through Conservation Agriculture and Nutrient Management in Central India

Land Degradation &Development, EarlyView.
ABSTRACT Maintaining soil health and crop productivity in the semi‐arid Vertisols of central India poses a significant challenge under intensive agricultural practices. This 6‐year field study assessed the combined impact of different tillage methods, maize‐based crop rotations, and nitrogen management on soil's physical, chemical, and biological ...

Waterproofing topsoil stockpiles minimizes viability decline in the soil seed bank in an arid environment

, 2014
Topsoil is a valuable resource for revegetation of mine sites as it contains seeds of plant species indigenous to the local environment. As mine site restoration is undertaken after the completion of mining, it is a common practice to stockpile topsoil ...

Explainable, Uncertainty‐Aware Machine Learning for Maize Land Suitability and Climate Resilience in Lorestan Province, Western Iran

Land Degradation &Development, EarlyView.
ABSTRACT Maize (Zea mays L.) is strategically important in Iran, yet its cultivation in the semi‐arid Zagros is constrained by limited and variable water, heat stress and heterogeneous soils, while conventional suitability assessments are deterministic, rarely validated spatially and provide no measure of confidence.

Globally widespread weeds show preadaptation to non‐analogue climates: a common garden approach

Oikos, EarlyView.
Climatic niche shifts have been documented for plant species introduced into new regions, however the underlying mechanisms are poorly understood. Niche shifts into novel climates are particularly difficult to predict as previous occurrence data cannot reveal whether these novel climates are within species' fundamental niche limits.
