Good soil tilth allows for a. hard, rocky soil b. decreased plant life c. decreased movement of air d. increased porosity

The correct answer is option D

The soil tilth can be defined as the physical condition of soil which defines the pattern of soil that is suitable for the growth of the plants.

Different plant needs different kind of soil for its growth. A soil with a good tilth has large pore size. This allows adequate amount of air supply which makes the soil rich in oxygen.

It holds a reasonable amount of water supply and nutrients.

increase soil erosion                                             reduce soil erosion

cattle grazing                                                         hydroseeding

deforestation                                                         contour plowing

                                                                                planting vegetation

plant roots basically hold the top soil

together and stop soil erosion because

in such situation top soil is not removed

during flood but cattle grazing causes

soil erosion because cattle consume the

grasses and herbs and top soil is exposed.

same situation occurs because of

deforestation, the trees and plants are cut

down to expose top soil which causes soil

erosion
