In northern boreal region the growth of forests is slow, and yield profit are low, which why low reforestation costs important for profitable forestry. If natural regeneration successful, expensive artificial forest (planting or direct seeding) can be avoided. this study, we look at impact overstory density site preparation on seedling Scots pine. Study stands were established in different part...

Black Silicon (BSi) is a semiconductor with surface modified to get very low reflectivity and correspondingly high absorption of visible light. P-type <100> silicon wafers were used prepare reflecting samples. These samples may use as substrates in optoelectronic applications. Electrochemical etching at different current, time applied. B-silicon chemically equal normal silicon, differs tr...

The mechanism of furrow opener-soil interaction plays an important role in analyzing the process no-till planting opener. In order to study disturbance effect opener on loam soil, firstly, three-dimensional model was established by using SolidWorks. Secondly, 3D discrete element EDEM software. Combined with indoor soil bin test bench and high-speed camera technology, micro-disturbance macro-dis...

The northeastern region (NER) of India has several complex regional geological structures, out which the Dauki fault (DF) is a prominent one. E–W trending reverse DF, inferred to go through southern margin Shillong Plateau (SP), played major role in deformation adjoining areas and was believed be active during Late Quaternary time. Previous paleoseismological studies conducted on eastern wester...

Characterization of material changes with depth (profiles) in many landfill sites can be problematic for some conventional geophysical methods. Localized anomalies within the landfill can complicate mapping of underlying layers, and layered-model techniques are inappropriate for imaging laterally discontinuous landfills. Recently-developed geophysical hardware and software tools provide the opp...

Moso bamboo forest (Phyllostachys heterocycla [Carr.] Mitford cv. Pubescens) is an important forest type in subtropical China and comprises an important pool in the global carbon cycle. Understanding the effects of the stand management, such as understory removal, on soil respiration (RS) will help to provide a more accurate estimation of carbon cycling and predict future climate change. The st...

The addition of biochar to agricultural soils has been shown to improve crop productivity and sequester carbon in soils over a millennial timeline. However, little formal research has assessed the logistics or economics of transitioning to a biochar economy. This paper examines the problem of biochar application to soil. Specifically, we look at two methods of application-broadcast-and-disk and...
