Pre-Columbian tribes in the northeast practiced a mix of agriculture, including growing crops such as maize, beans, and squash. They used a system called "slash and burn" agriculture in which they cleared land by cutting and burning vegetation before planting crops. These tribes also practiced crop rotation and intercropping to maintain soil fertility and maximize yields.
Turfing in the medical field is a negative term meaning getting a patient out of your area and into someone else's. I believe it was made famous by Samuel Shem's House of God.

Irrigation is the artificial application of water to soil, and there are several types of irrigation systems which work in different ways. The most common method is surface irrigation (or flood irrigation), wherein water moves across land by gravity flow. Localized irrigation, on the other hand, distributes water under low pressure through a piped network, in a pre-determined pattern, and applied as a small discharge to each plant or adjacent to it. Drip irrigation, also known as trickle irrigation, functions as its name suggests. Drip irrigation (or trickle irrigation) delivers water at or near the root zone of plants, drop by drop. In sprinkler irrigation (or overhead irrigation), In sprinkler or overhead irrigation, water is piped to one or more central locations within the field and distributed by overhead high-pressure sprinklers or guns. There are several other types, but all have in common that they provide the appropriate amount of water to crops via an artificial system of distribution.
Irrigation is the process of supplying water artificially to the plants through land or soil. Some of the commonly used irrigation types are surface irrigation, localized irrigation, sprinkler irrigation, sub irrigation, automatic irrigation and in-ground irrigation.
Examples of irrigation system are,Perennial irrigation (Dams)Direct irrigation (river canal irrigation)Storage irrigation (tanks and resevoirs)

They created a series of irrigation ditches to bring water to their crops. This civilization pre-dated Egypt by at least one thousand years.
