Dynamic response of an alluvial valley consisting of three different types of soil was studied. In the two-dimensional model, the alluvial valley was assumed to have half-cylindrical shape. The alluvial valley contained three different types of soil with different shapes. The valley was surrounded ...
MAJOR TYPES OF SOIL DEPOSITS IN URBAN AREAS IN JAPAN By taking into account the geological processes of formation of alluvial and diluvial soil deposits, it has been found that the soil deposits are classifie... Y Ohsaki,O Sakaguchi - 《Soil & Foundation》 被引量: 2发表: 2008年 pH ...
Laboratory experiment was conducted to understand the persistence behavior of tetraconazole in three soils of West Bengal (alluvial, red lateritic, and coastal saline) and also in water maintained at three different pH (4.0, 7.0, and 9.2) conditions. Processed soil samples (100 g) were ...
e., alluvial and volcanic ash soils. The results obtained are as follows :1) Potted chrysanthemums grown on alluvial soil markedly exceeded those grown on volcanic ash soil in such attributes as size and weight of single leaves, leaf number per lateral shoot, and weight of inflorescences per ...
The summer temperature of nearly 100° F. drops in winter to - 70°. The mean annual precipitation is about 12 in. The important types of forest soils include lithosols and regosols, alluvial soils, melanized raw-humus soils, micro-podzols, half–bog soils, lowmoor peat, highmoor bog ...
Soil pollution, or soil contamination, is the accumulation of man-made toxic substances in soil that has a negative effect of plant and animal life. Common pollutants include herbicides and pesticides; litter and waste. Soil pollution is usually caused by mistreatment of the soil through poor cult...
The objectives of this study were to determine if apparent electromagnetic conductivity (EC(a)) alone or combined with previous year crop yields using global positioning system technology can provide a useful alternative to detailed soil mapping. The site contained alluvial soils ranging from Bojac 1...
Alluvial sediment is a term for material, typically silt (but also sand, gravel or other material), that is deposited on a land form by water action. As a stream approaches its mouth it becomes wider, and the current moves slower. This slowing of the current allows for the deposit...
The difference of the SHI of the three soil types was significant at P = 0.05. The paddy soil had the highest SHI values, followed by the gray alluvial soil, and the coastal saline soil was in a poor soil health condition, indicating a need to plant some salt-tolerant crops to ...
13 Different Types of Spruce Trees 1. Blue Spruce or Picea Pungens f. Glauca One of the most popular evergreens with silver blue-grey needles, Blue spruce is also known as Colorado Blue spruce. With a preference for full sun and any kind of well-draining soil, a Blue Spruce grows rather...
