Moderate Biochar–Compost Mixture Is More Effective in Improving Biomass, Nutrient Fluxes, and Photosynthetic Outputs for Sustainable Land Restoration and Soil Fertility

Land Degradation &Development, EarlyView.
ABSTRACT Soil nutrient depletion severely constrains crop productivity in degraded and saline environments. Strategies such as biochar–compost integration could be useful for sustainable agriculture and land restoration on a global scale. This study evaluated the effects of biochar (1% Bc), compost (1% Co), and their blends (0.5% Bc + 0.5% Co and 1% Bc

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,

Universal growth modes of high-elevation conifers [PDF]

, 2016
In order to characterize the main growth modes of high-elevation conifers, such as typical variations inherent to annual tree growth records, we resolved eigen problems related to intra-record correlation coefficient matrices of several large sample sets

Synergistic Regulation of Soil Function and Wind Erosion Resistance by Sand Barriers, Vegetation, and Artificial Biological Crust in the Tengger Desert

Land Degradation &Development, EarlyView.
ABSTRACT Aeolian desertification poses a critical threat to ecosystem stability in arid regions worldwide. Although the combination of sand barriers and vegetation has been widely applied for sand fixation, its long‐term effectiveness is constrained by barrier degradation, slow natural development of biological soil crusts (BSCs), and the resulting ...

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 ...
