Measurement of Vertical Water Percolation Through Different Soil Textures of Paddy Field During Rice Growth Season
The water percolation loss beyond root zone in the soil is one of the important parameters to determine water requirement of rice plant. If the amount of water percolation rate into the soil is estimated more carefully, determination of water requirement will be evaluated better and designing for system of irrigation, drainage and related establishments will be more easily done. The purpose of ...

Puddling is the most common method of land preparation for lowland rice cultivation. The purpose of this study was to assess the influence of various intensities of puddling on percolation rate, water retention by soil and the amount of water used for different puddling intensities in three dominant soil textures of paddy fields in Guilan province. Undisturbed soil samples were taken from 3 dif...
متن کاملSustainable Covers for Uranium Mill Tailings, Usa: Alternative Design, Performance, and Renovation
The U.S. Department of Energy Office of Legacy Management is investigating alternatives to conventional cover designs for uranium mill tailings. A cover constructed in 2000 near Monticello, Utah, USA, was a redundant design with a conventional low-conductivity composite cover overlain with an alternative cover designed to mimic the natural soil water balance as measured in nearby undisturbed na...
متن کاملA Mechanical Shaker for Sieving Dry Soil Samples
E.I. Ekwue 2 The design, construction and testing of a soil dry sieving apparatus, which could be used to effectively determine the particle size distribution curves of dry soil samples is described. The design required that a means be developed to agitate soil samples placed on two stacks of sieves, each arranged in decreasing sizes.
