Determination of soil texture by using the volume percent can be simpler than the method hydrometer. The principle of determination based on the percent of this volume is based on the speed of precipitation. Wherein the fraction of the rough or the sand will settle early (1 minutes before turning it) and then followed by the fraction of the dust ...

Determination of the texture in the field is done by 1) the period of dry or moist soil is wetted, then dipirid between the thumb and forefinger so memebntuk ribbon moist, as he felt a sense of rough, slippery and sticky; 2) the land made the ball, rolled up and observed their resistance to compression and adhesion Masaa ground when ...

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, ...

Chemical parameters of the water can not only be measured using digital equipment, but there is also a water quality measurement method using titration methods or staining. Here below is the equipment used in the measurement of water quality parameters by titration can be seen in Table 17. Table 18. Equipment used for the measurement of water quality by titration

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 ...

For water quality monitoring, sampling time interval is set on a different day and time, so it can be differences in the quality of water every day and every hour. For example, if the first sampling is done on Monday at 06.00, then the sampling is then performed on Tuesday at 07.00, etc. Frequency of sampling The frequency of sampling ...
