Sample Handling Techniques

After sampling, water samples should be analyzed immediately. If forced to be stored, any water quality parameters require specific treatment to the sample. In addition to treatment with chemicals, preservation of the most common is the cooling at a temperature of 4 ° C during transportation and storage. At this temperature, bekteri activity is inhibited. Samples were delayed measurement and ...

Agricultural Soil Productivity

The productivity of agricultural land is an economic concept that is determined by three factors, namely: (1) land management system, (2) results (of production), and (3) the type of soil. The value of agricultural land is highly dependent on the value of land productivity, more productive, then the higher the value of agricultural land. In the management of farmland there ...

Determination of Soil Texture With Feelings

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 ...

Based Soil Texture Volume

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 ...
