To call something "marginal" means it is not very good. Farmers have their own way to【47】marginal land: It is the last to be planted under good conditions, and has the【48】to be avoided under poor conditions.

Grass seed can be bought from a foreign supplier or【52】grasses can be used. However, using marginal land for grazing is not a simple issue. There is a【53】of overgrazing.

A(n)【54】way to reduce the harm is to move animals from one field to another. This method is known as rotational grazing (循环放牧) which is extremely important for marginal land.
Another use for marginal land is for tree crops. Studies have【55】that the white pine and loblolly pine (火炬松) are two kinds of trees that grow well on such land. They grow fast and provide good quality wood. Another tree is the poplar (白杨), found in many parts of the world.

A) feed B) priority C) transplant D) effective
