In agriculture, a terrace is a piece of sloped plane that has been cut into a series of successively receding flat surfaces or platforms, which resemble steps, for the purposes of more effective farming. This type of landscaping is therefore called terracing. Graduated terrace steps are commonly used to farm on hilly or mountainous terrain.
A water channel to drain and irrigate andenes. Andenes were complicated to build, requiring provisions for drainage and irrigation. The first step in constructing an andén was to lay an underground or bedrock foundation about 1 metre (3.3 ft) deep to lend strength and stability to the retaining wall, which might rise about 2 metres (6.6 ft) above the slope of the ground.
The Inca agriculture system not only included a vast acreage of crops, but also numerous herds, some numbering in the tens of thousands, of animals, some taken by force from conquered enemies. [9] These animals were llamas and alpacas , the dung of which was used to fertilize the crop fields. [ 9 ]

The agriculture terraces are a feature of the complicated drainage system; the steppes helped avoid erosion and were built on a slope to aim excess water into channels that ran alongside the stairways. These channels carried the runoff into the main drain, avoiding the main water supply.
The Ifugao complex of stone or mud walls and the careful carving of the natural contours of hills and mountains combine to make terraced pond fields, coupled with the development of intricate irrigation systems, harvesting water from the forests of the mountain tops, and an elaborate farming system.
The difficulty of planting kalinayan and other rice varieties with the soil type in these areas leads to the building of the rice terraces entailing construction of retaining walls with stones and rammed earth which are designed to draw water from a main irrigation canal above the terrace clusters. Indigenous rice terracing technologies have ...
Systematic ploughing, manuring, weeding, irrigation and crop protection was practiced for sustained agriculture. [45] Water storage systems were designed during this period. [1] Kallanai (1st-2nd century CE), a dam built on river Kaveri during this period, is considered to be one of the oldest water-regulation structures in the world still in ...
