1. Monocropping:

monocropping

It is the practice of growing one crop on a farm year after year

Advantages of Monocropping:

Farming efficiency.

(i) The crop is the same over the whole farm, therefore farming-management decisions are simplified.

(ii) Only the machinery necessary to maintain the crop needs to be purchased.

(iii) The seasonal work is predictable allowing scheduling of casual labour (e.g., harvesting) and contract machinery.

(iv) Maximises the financial return and minimises costs.

Disadvantages of Monocropping:

(i) It destroys the soil structure leading to soil erosion.
