1 SOIL TEXTURE GEOGRAPHY 6A
CAMERON LAWRENCE

2 WHAT IS SOIL TEXTURE ? The term soil texture refers to the degree of coarseness or fitness of the mineral matter in the soil. It is determined by the proportion of sand , silt and clay particles. *NOTE- Particles larger than sand are grouped together and described as stones.

3 SANDY SOIL: SANDY SOIL FEELS GRITTY AND LACKS COHESION.

4 SILTY SOIL: A silty soil has a smoother, soap like feel as well as having some cohesion.

5 CLAY SOILS: A clay soil sticky and plastic when wet and being very cohesive, maybe rolled into various shapes.

6 SOIL TESTING: there are several ways to test soil samples three easy to do test are by feel, sieving and sedimentation. 1) FEEL:

7 SOIL TESTING CON’T: 2) SIEVING:

8 SOIL TESTING CONT: 3) SEDIMENTATION:

9 SOIL TEXTURE ANALYSIS (TRIANGULAR GRAPH)

10 THE IMPORTANCE OF TEXTURE:
As texture controls the size and spacing of soil pores, it directly affects the soil water content, water flow and extent of aeration. * TEXTURE GREATLY INFLUENCES SOIL STRUCTURE.

11 CONCLUSION: HOW DOES TEXTURE AFFECT FARMING
