Choose the correct answer using the codes below:
A) 1 and 2
B) 2 and 3
C) 1 and 3
D) All of the above

Answer : D) All of the above

Explanation :
Mulching is one of the simplest and most beneficial practices you can use in the garden. Mulch is simply a protective layer of a material that is spread on top of the soil. Mulches can either be organic -- such as grass clippings, straw, bark chips, and similar materials -- or inorganic -- such as stones, brick chips, and plastic. Both organic and inorganic mulches have numerous benefits.

Protects the soil from erosion
Reduces compaction from the impact of heavy rains
Conserves moisture, reducing the need for frequent waterings
Maintains a more even soil temperature
Prevents weed growth
Keeps fruits and vegetables clean
Keeps feet clean, allowing access to garden even when damp
Provides a "finished" look to the garden

Organic mulches also improve the condition of the soil. As these mulches slowly decompose, they provide organic matter which helps keep the soil loose. This improves root growth, increases the infiltration of water, and also improves the water-holding capacity of the soil. Organic matter is a source of plant nutrients and provides an ideal environment for earthworms and other beneficial soil organisms.
While inorganic mulches have their place in certain landscapes, they lack the soil improving properties of organic mulches. Inorganic mulches, because of their permanence, may be difficult to remove if you decide to change your garden plans at a later date. Therefore, this tip sheet is limited to the use of organic mulches
