The 100 m false-colour image of 4 April 2016 shows us Dalhart in Texas. Dalhart's economy is centered around agribusiness, including farming, ranching, feedlot operations, large scale pig farms, and, more recently a cheese processing plant. During the peak operating period of the cattle ranch (1885 to 1912), the land was in native grass. Some land was diverted into dry farmland, but there was insufficient rain to make it productive. A few irrigation wells were drilled in areas where the soil was not sandy and was level enough for row irrigation. Later, center pivot irrigation was introduced and was found to be ideal for the area's rolling sandy soils. About the same time frame, large feedlots were built due to the low-humidity climate. This created a good market for corn, which is the major crop grown by farmers in the area.
