• Chapter 2. Production and Processing of Aluminum

    Production and Processing of Aluminum Extraction of Aluminum The extraction of aluminum from its ore and subsequent processing into finished products takes place in a series of successive operations, each largely independent of the other. Generally the various processes are carried out at different plant sites. A summary of production steps from the bauxite mine through casting is given ...

  • Nutrient Management

    High clay content increases CEC and thus the ability to hold nutrients, while high sand content decreases the CEC and nutrient holding capacity. Sandy soils also have large pore spaces, allowing more leaching of nutrients. See the next page for a diagram of various soil texture characteristics. A diagram provided in the next few pages demonstrates the different components of soil texture.

  • Understanding Soil Texture and Structure

    Clay is the smallest size soil particle. Clay has the ability to hold both nutrients and water that can be used by plants. It creates very small pore spaces, resulting in poor aeration and poor water drainage. Clay forms hard clumps when dry and is sticky when wet. TABLE 1.

  • Absorption of Minerals

    Water logged soils or soils with higher content of clay have very little amount of air; under such conditions roots are subjected to anaerobic conditions and the absorption of minerals is drastically affected. The inhibition of absorption of minerals due to the effect of respiratory poisons on roots clearly suggests that the absorption of minerals is an energy dependent process.
