Consistency

In the Basic Sciences of the soil, there are several kinds of soil properties. On this occasion, will be explained about consistency. Consistency is the soil's ability to retain the shape of land size, due to pressure from outside the force of cohesion and adhesion. There are several kinds of consistency, ie:
1. Wet 

    a. Sticky: not sticky, somewhat sticky, sticky, and 

        very sticky
    b. plastically: no plastic, somewhat plastic, plastic, and

        highly plastic
2. Dried
    freelance, somewhat hard, hard, and very hard
3. Moist
    friable, somewhat firm, firm, and very firm.

To measure the consistency can be done in two ways, ie:
a. Qualitative methods
This method is done by determining the resistance of the land mass of the pressure or massage hands on a variety of soil moisture content.
b. Quantitative Methods
This method is termed as the number Atterberg. This method is done by stating the number of water content in the liquid limit and plastic limit of a soil.

There are several factors that are influenced by the consistency, ie:
a. root crops
if the soil has a friable consistency (clay), so root crops will be easy to move in the ground

b. organism
if the soil has a friable consistency, it will be easy living organisms and easy to breed in the soil
c. tillage
if the soil has a friable consistency, it would be easy to do tillage
d. erosion
more strong consistency of the soil, the erosion will often happen
