Significantly more occlusion bodies (OB) of DuPont viral construct HzSNPV-LqhIT2, expressing a scorpion toxin, were transported by artificial rainfall to cotton plants from sandy soil (70:15:15 sand-silt-clay) than from silt (15:70:15) and significantly more from silt than from clay (15:15:70). The amounts transported by 5 versus 50 mm of precipitation were the same, and transport was zero when...

this paper attempts to examine the effect of water spreading on soil physico-chemical properties, and vegetative characteristics of common mesquite. for this, on the basis of flood water discharge, three sections of lands were accurately selected at kosar water spreading experimental station, in tangestan, bushehr province. in each section, 6 profiles were digged out and studied; meanwhile soil...

Artificial fill (Holocene)—Mud, sand, and gravel of varying proportions, possibly including foreign debris such as concrete, logs, timbers, or brick. Used for highway roadbeds and other construction. Thickness generally greater than 2 m. Mapped where fill substantially obscures or has altered original geologic deposit. Beach deposits (Holocene)—Soft sand, silt, and mud deposited or reworked by ...

The mineralogical investigation, geochemical analysis, and grain size calculation were carried out for floodplain sediment in the Tigris River to identify properties of sediment. average values three main classes, very fine sand, silt, clay are 9.67, 62.53 27.80%, respectively. silt fraction was predominant. classification nomenclature surface types from sandy-silt mud, they dominant Statistica...

Genetic fingerprinting demonstrated in previous studies that differently sized soil particle fractions (PSFs; clay, silt, and sand with particulate organic matter (POM)) harbor microbial communities that differ in structure, functional potentials and sensitivity to environmental conditions. To elucidate whether specific bacterial or archaeal taxa exhibit preference for specific PSFs, we examine...

Soil surface texture is an important environmental factor that influences crop productivity because of its direct effect on soil water and complex interactions with other environmental factors. Using 30-year data, an agricultural system model (DSSAT-CERES-Wheat) was calibrated and validated. After validation, the modelled yield and water use (WU) of spring wheat (Triticum aestivum L.) from two ...

Guan S., An N., Liu J.H., Zong N., He Y.T., Shi P.L., Zhang J.J., He N.P. (2018): Warming impacts on carbon, nitrogen and phosphorus distribution in soil water-stable aggregates. Plant Soil Environ., 64: 64–69. A five-year (2010–2015) field experiment was conducted to investigate warming impacts on organic carbon (OC), total nitrogen (TN) and total phosphorus (TP) contents and their ratios in b...

This study is based on the Shihmen Reservoir silt, where the largest quantity of silt is deposited and is located right next to the National Taiwan University of Art, and with combinations of other simple components, like various kinds of clay, plant ashes or other raw materials, to produce quality glazes that can perform artistic charm and give great additional values. The development of the n...
