Geological Journal, EarlyView.Our petrochemical studies on ~1.2 Ga granitoids of the Natal Metamorphic Belt, South Africa, do not suggest any property similar to Phanerozoic‐style subduction‐related granitoids. Plot of Kotongweni Tonalite in Y versus Sr diagram (after Moyen 2011), note that most samples have Sr/Y < 50.

Breeding switchgrass for reduced nitrogen demand
Grassland Research, EarlyView.Breeding has improved switchgrass biomass yield, but productivity is still heavily dependent on nitrogen fertilizer application. The genetic diversity needed to improve nitrogen use efficiency of switchgrass remains underused, mainly because of the slow and laborious breeding process, thus leaving the crop's high nitrogen demand as a major barrier to ...

The effect of awns on seed yield and germination characteristics in Elymus nutans Griseb.
Grassland Research, EarlyView.The effect of awns on seed yield. Three‐year field trials demonstrated that awns significantly regulate seed yield components and germination characteristics of Elymus nutans Griseb, laying a theoretical foundation for the breeding of high‐yielding forage varieties and seed production.

Irrigation and Drainage, EarlyView.ABSTRACT Accurate monitoring of crop water use is critical for precision irrigation, yet conventional lysimeter systems remain too costly and complex for widespread adoption. This study presents the development and field validation of a low‐cost, information and communication technology (ICT)‐enabled weighing lysimeter system that integrates load cells,

BoreasClast‐fabric analysis is a widely used method for investigating depositional and deformation processes in glacial sediments. However, traditional field‐based approaches lack standardization, are time consuming and introduce sampling bias.

Two-dimensional apparent microfabric of the basal Late Weichselian till and associated shear zone: case study from western Latvia [PDF]
Estonian Journal of Earth Sciences, 2008 The examination of glacial sediments in thin sections has become a common procedure in recent years. Apparent sand grain orientation (microfabric) in thin sections is one of the key elements marking certain microstructures.

Mechanical properties of soils in internal waste bank of lignite mines and their primary characteristics [PDF]
Archives of Civil EngineeringThe modern development of urban areas is related to, among others, the location of industrial facilities on the outskirts of cities. More and more often, commercial buildings are founded on areas that have not been used for construction so far.
