B: Loess

Loess is aeolian deposit also identified as fine sediments which are created by the gathering of wind-blown deposit, typically in the 20–50-micrometer size spectrum, 20 percent or less clay and the balance corresponding parts debris and sand which are loosely bonded by calcium carbonate making the finest sediments.

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.
