Q. EXPLAIN THE RELATIONSHIP MAINTAINED BETWEEN SOIL AND HUMAN ACTIVITIES.
ANALYZE THE INFLUENCES OF SOIL ON ECONOMIC ACTIVITIES.
DRAW THE RESULTS COMBINING HUMAN ACTIVITIES WITH THE SOIL.
The influences of sod are very prominent and decisive on the agricultural activities. Agriculture activities are possible in the regions only where the soil is fertile either due to the natural conditions or it has been made fertile through the artificial means.
If all other factor is highly favourable but the soil is not fertile, the agricultural activities can’t take place in such areas. It is decided by the soil that which crop should be sown and grown on what kind of and because the soil of a particular kind can’t be suitable for all the crops. For instance, the jute is cultivated successfully on the coastal areas of Bangladesh because the proportion of required mineral salts is found in that soil.
Cotton can’t be cultivated on the Eastern Coastal areas of America because soil is sandy. Contrary to this, the black soil of Texas is highly fertile for the cultivation of cotton.
Soil plays the key role also for growing trees. For catching hold of roots of the trees, it is required that this capability should be embodied in the soil. If the soil can have the catch hold of the roots of the trees, they could stand straight and water that reaches to the roots after passing through the soil, provide the food to the trees. On the contrary, if the surface (soil) is hard and compact, it would resist allowing the roots to penetrate in deep and so the trees can’t stand. This is the reason that ‘Domat’ soil is taken as suitable for the trees. The saltesh soil of deserts does not suit for the plants but the acidic soil of forests is highly suitable for this purpose.
