A soil, plant and water testing laboratory with an annual analysing capacity of about 10 –12 samples requires a building space of about m2. For a fertilizer testing laboratory with an analysing capacity of 2 samples, the space requirement is about m 2. A . Most laboratory tests in soil mechanics require the determination of water content. Water content is defined as weight of water present in a given soil mass w = weight of dry soil () Water content is usually expressed in percent. For better results, the minimum size of the most soil specimens should be approximately as given in Table

Add clean water to the aggregate in increments of % of dry aggregate weight. After adding each increment, mix thoroughly by hand. Repeat until the surface of the aggregate is moistened and very little free water is present. Add the pre-determined amount of emulsion to the moistened aggregate.
