Soil TextureNatural RadionuclidesIn this research, a gamma ray sensor (The Mole) was used to get the natural radionuclides concentration in in the surface layer of cultivated soils. For sand, silt and clay predictions, an adaptive neuro fuzzy inference system (ANFIS) was performed to predict ...
Ammonium acetate lactate-extractable K (K-AL) was rapidly depleted, and in K0 the K-AL level stabilized at 30 and 100 mg K kg -1 in the silt and clay soil, respectively. Corrected for different ''minimum'' values, the K-AL value predicted the K uptake by ryegrass from AL extractable...
Without a microscope, sand, silt, and clay soil particle sizes are impossible to measure directly so sediment testers determine the coarse fractions by separating the size grades with precision sieves and weighing them. For the smaller particles, they use tests based on how fast the different size...
•Water covers a large proportion of the earth's surface. 水覆盖了地球表面的大部分。 •Loam is a soil with roughly equal proportions of clay, sand and silt. 壤土是由大约等份的黏土、沙和粉砂合成的。 •The proportion of regular smokers increases with age. 习惯吸烟的人口比重随年龄的增长而...
Organic refuse application to soil may improve soil structure and thus soil quality and productivity. Two semiarid, structureless soils with < 10 g kg(-1) organic C (OC), differing in clay mineralogy, were amended annually at rates of 30 g kg(-1) fresh or composted refuse to a total ...
