A root of a cotton plant must
overcome various potential forces such as gravitational forces that pulls water
downward, matric forces where there is an adhesion of water molecules from a soil and osmotic forces where attracting water in the presence of large amount of soluble salts in the mixture of soil.
If the soil were compacted by
a heavy vehicle, the matric forces would be mostly affected for compaction will
result to increase matric forces due to reduced size of pores of the soil
making it more difficult to draw water from a solid surface.
Answer:# 1 is salt #2 is fresh #3 fresh #4 salty
