THE INFLUENCE OF TECHNOLOGICAL PROGRESS ON THE LONG RUN FARM LEVEL ECONOMICS OF SOIL CONSERVATION [PDF]
The complementary interaction between topsoil depth and technical progress for winter wheat in the Palouse region was found to strengthen the long run payoff to conservation tillage.

Land Degradation &Development, EarlyView.ABSTRACT Soil carbon‐nitrogen‐phosphorus (C:N:P) stoichiometry governs nutrient cycling and carbon sequestration in desert ecosystems, yet how large‐scale photovoltaic (PV) deployment, a cornerstone of global carbon neutrality, shifts these stoichiometric balances and whether such shifts enhance or degrade long‐term land function remain unresolved over

The effect of topsoil on pavement performance [PDF]
, 1964 A laboratory study was undertaken and a field test section was constructed to study the rate of pavement deterioration which results when topsoil is used in construction of a subgrade.

Formation and degradation of immature laterites in response to paleoclimatic changes in the eastern Amazon [PDF]
Brazilian Journal of GeologyLateritic formations are widespread in eastern Amazon, occurring as bauxite-bearing mature profiles on plateaus or as immature ones in lowlands. Climate and landscape evolution over the Neogene were analyzed via mineralogical (XRD), textural (optical ...

Land Degradation &Development, EarlyView.ABSTRACT Urban expansion can substantially reshape ecosystem structure and functioning, especially in ecologically fragile Karst landscapes. Clarifying how ecosystem health (EH) responds to urbanization and identifying the factors that drive spatial variation in EH are important for regional sustainability.

Phosphorus nutrition of chickpea under dry topsoil conditions as in the High Barind Tract of Bangladesh [PDF]
, 2012 In many parts of the world, notably in South Asia, crop intensification is resulting in more crops being grown on stored soil moisture, under which conditions the topsoil commonly dries out during crop growth.

Land 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

Land Degradation &Development, EarlyView.ABSTRACT Land degradation threatens agricultural and forestry economies by lowering productivity, raising input costs, and increasing risk. This study examines whether Internet of Things applications moderate these losses in 1321 mainland Chinese counties from 2011 to 2024. Land degradation is measured separately through vegetation trends, modeled soil

Land Degradation &Development, EarlyView.ABSTRACT Soil salinization negatively impacts the economic development and ecological environment, particularly in the arid and semiarid regions of China. The Qaidam Basin constitutes a major distribution area of saline‐alkali land in the country. However, the distribution patterns of salinity and nutrients within soil profiles and the underlying salt ...
