WebEstimate soil texture by the feel method. II Introduction A General Soil texture is the relative proportion of sand, silt, and clay in a soil. Within each of these soil separates there is a continuum of particle sizes. Thus, there is a particle size distribution in soil ranging from the largest sand particles to the smallest clay particles. Webcontent of the leaves was determined by polarography. The assays of mineral elements were carried out according to Lu et al (2000). Whereas, the Si content of the leaves was determined based on standard assays (LY/T 1270-1999). All items were used to control and test the quality with standard material GBW07603. 2.4.

WebThe soils used in this experiment differed in potential nitrogen availability—from previous studies they were known to have different rates for nitrogen mobiliza- tion. The soils were combined with sand to give a porous mixture. The pots containing the soils were embedded in sand to stabilize the soil temperature (Plates 3 and 4).
