What is smothering in plants?
Smothering weeds is the process of depriving them of light and water until they starve.

| Increased water infiltration | Addition costs (planting and killing) |
What is ley farming?
Definition of ley farming
: the growing of grass or legumes in rotation with grain or tilled crops as a soil conservation measure.
What is the difference between intercropping and strip cropping?

What is terrace farming?
terrace cultivation, method of growing crops on sides of hills or mountains by planting on graduated terraces built into the slope. Though labour-intensive, the method has been employed effectively to maximize arable land area in variable terrains and to reduce soil erosion and water loss.
What is the 4 crop rotation?
The sequence of four crops (wheat, turnips, barley and clover), included a fodder crop and a grazing crop, allowing livestock to be bred year-round. The four-field crop rotation became a key development in the British Agricultural Revolution. The rotation between arable and ley is sometimes called ley farming.
