Which agricultural technique is associated with the Inca civilization?

The Inca civilization is particularly well-known for its innovative use of terrace farming. This technique involves creating stepped platforms on the sides of mountains or hills, which optimizes arable land usage in challenging terrains. By building terraces, the Incas were able to cultivate crops on steep slopes, minimizing soil erosion and allowing for better water retention.

Terrace farming was crucial for the Incas as it enabled them to grow various crops, including potatoes and maize, which were essential for their diet and agricultural economy. The modification of the landscape not only enhanced agricultural productivity but also facilitated the expansion of their agricultural practices in the rugged Andean environment.

The other options provided describe various agricultural practices that are either modern or not specifically linked to the Incas, thereby further emphasizing the uniqueness and significance of terrace farming in their civilization.
