Step-by-step explanation:
What is Afforestation ?
Afforestation is the process of planting trees or sowing seeds in a barren land so as to create a forest .
It is important because it helps check the over-use of natural resources by providing an alternative
source pool. Basically it is the creation of a new forest.
Why is Crop Rotation important ?
Crop rotation helps to maintain soil structure and nutrient levels and to prevent soil borne pests from
getting a foot hold in the garden.
When a single crop is planted in the same place every year, the soil structure slowly deteriorates as the
same nutrients are used time and time again. So in order to prevent the soil from losing its fertility
different crops are planted in a systematic manner according to their requirements.
What is Fallowing ?
Fallow ground or fallow soil, is simply ground or soil which has been left unplanted for a period of time
In other words, fallow land is a land left to rest and regenerate . So, a field or several fields are taken out
of crop rotation for a specific period of time, usually one to five years, depending on the crop.

a) How do trees help in soil conservation ?
a.. Trees hold back the soil with the help of roots. As the trees grow taller and older, their roots
becomelonger and dig deeper into the ground. The network of roots inside the soil holds it in
place, particularly in the rainy season. This also supports the water retention capacity of the
soil. Moreover, trees also act as a vegetative cover for the soil, thus preventing the top soil
from being blown away by the wind.
b) What is crop rotation ?
b) When a single crop is planted in the same place every year, the soil structure slowly deteriorates as
the same nutrients are used time and time again. So in order to prevent the soil from losing its fertility
different crops are planted in a systematic manner according to their requirements. This process is
known as crop rotation.
