It was apparent that the soil broke up on tillage into the usual range of aggregate sizes plus a dust which was presumably composed of micro-aggregates. This was apparent on sections through the blocks which showed three components: voids, aggregates and dust. A statistical method for ...

40% silt and 20% clay. This combination of soil components holds nutrients and water, while draining well. Loam comes in various gradations—sandy loam, silty loam, loamy clay—each with a slightly different composition.

A new method of acquiring three components of surface deformation using three SAR interferograms with different satellite's line of sight is presented. To verify this method, interferograms of two type ideal surface deformations are modeled with three group of satellite orbits data. Then the differenc...
Two field experiments were conducted at the Research and Production Station, National Research Centre, El-Nubaria Province, El-Behira Governorate, Egypt, during the two successive winter seasons of 2010/2011 and 2011/2012 to study the response of yield and yield components of three flax cultivars...
A prepn. for detoxification of cultivated agricultural soil, rivers and ponds contains three mineral silicates, i.e.: 40 wt.% klynoptylolite, 40 wt.% mardenite, and 20 wt.% diatomaceous-earth. Following optimum dosages are used: 10-15 g/sq.m on cultivated land, 20-25 g/sq.m in ...

Passivation mechanism of lime and phosphate is relatively simple16. However, soil is not a homogeneous body, and the partitioning of different matter components in soil particles with different sizes is not uniform. Many specific reactions or phenomena only occur within a specific range of soil ...
