Suitable climatic conditions and large scale alluvial deposits have helped in the cultivation of rice on such a scale. Over two-thirds of the production comes from Medinipur, Bardhaman, Twenty four Parganas, Bankura, Birbhum and West Dinajpur districts. The other producing districts are Haora, ...
Profile distribution was investigated for total and DTPAextractable Zn, Cu, Mn, and Fe in soils developed on three physiographic zones (alluvial terraces, interdunal areas, and sand dunes) in the arid zone of Punjab in northwest India. Total and DTPAextractable micronutrient cations were highest ...

Usually, the stratified summation method is used in estimation of SOC concentration at small...
2018). Aquifer sediments deposited in the Late Pleistocene to Holocene are mainly composed of Yellow River bed-load sediments carried from upstream or alluvial/fluvial deposit from the surrounding Lang Mountains, which both can have different weathering intensities (Cai et al. 2019). Furthermore, ...
This study was carried out to develop a conceptual framework for determining the best interpolation method which mainly is employed to calculate the variability maps of electrical conductivity (EC) in neighboring regions. The considered case study is par
In this context, it should be very important to prospect and conserve the wild parentals of the current crops as wild grapevine is. Moreover, some wild grapevine populations show a higher tolerance to pests and diseases [15] or to soil lime [16], [17] and, possibly, to saline soils [...

(Suixi County) with a total area of 2714 km2. Xiangshan mountain lies in the north of Huaibei with a height above sea level of 342 m. The terrain is flat, high in the northwest and low in the southeast. The quaternary sediments are mainly alluvial deposits, followed by alluvial prolu...
Radionuclide distribution in alluvial sediments and among fractions of the soil in the region of the Balchug settlement is analyzed, making emphasis on the contribution of the clay fraction to accumulation of radionuclides.doi:10.1007/s11137-005-0020-yV. G. Linnik...
alluvial fan areas at altitudes of 1000−1,300 m59. Therefore, over time, the distribution center ofT. mongolicamay migrate eastward along the horizontal gradient, with minimal changes in the vertical gradient. Due to factors such as the soil environment, the migration distance ofT. mongolicais...
