Soil Texture Determination In Laboratory

Soil is composed of soil grains of various sizes. Part grain land measuring more than 2 mm is called coarse material soil such as gravel, coral to rock when analyzed eliminated terelebih advance, as well as the organic material in the soil, so all that remains is fractions of land measuring less than 2 mm , Part ground grain size ...

Soil Biological Function

Biological soil serves as a habitat for organisms that participate actively in the provision of nutrient and growth boosters substances (additives) for plants, which are integrated capable of sustaining the productivity of the land to produce biomass and production of food crops, medicines, industrial estates, forestry and so on other. As a growing medium, the soil has four main functions, ...

Fraksi Pasir dan Debu

Fraksi pasir umumnya didominasi oleh mineral kuarsa (SiO2) yang sangat tahan terhadap proses pelapukan, sedangkan fraksi debu biasanya berasal dari mineral feldspar dan mika yang cepat lapuk, dan pada saat pelapukannya akan membebaskan sejumlah hara, sehingga tanah bertekstur debu umumnya lebih subur dibandingkan tanah bertekstur pasir. Dari penjelasan ini menunjukkan bahwa fraksi pasir dan debu lebih berperan secara fisik, sedangkan ...

Determination of Levels Alkalinity

Alkalinity is a total concentration of alkaline elements contained in water and commonly expressed in mg / liter or the equivalent of calcium carbonate (CaCO3). It is said that the alkalinity in freshwater very important role because alkalinity is not only a direct effect on the growth of plankton, but also affects other parameters. Alkalinity is the capacity of water ...

Suspended Solids and Total Dissolved

Total suspended solids or Total Suspended Solid (TSS) is suspended materials and dissolved in water, these materials filtered on Millipore filter paper with a pore size of 0.45 lm. While total dissolved solids are dissolved materials that are not filtered by Millipore filter paper with a pore size of 0.45 lm. TSS measurement is done by gravimetric consisting of screening ...

Brightness and Water Depth

One way to measure water transparency is done by using pieces Secchi (Secchi disk), which is a round pieces with a diameter of 20 cm made of zinc and painted white or black-white weighted. The tool is lowered into the water until it looks, its depth was measured, then lowered deeper. Furthermore, the chip is removed and when the puck ...
