Row crop in the context of Drill (agriculture)

Rice production is the fourth largest among cereals in the United States, after corn, wheat, and sorghum. Of the country's row crop farms, rice farms are the most capital-intensive and have the highest national land rental rate average. In the United States, all rice acreage requires irrigation. In 2000–09, approximately 3.1 million acres in the United States were under rice production; an increase was expected over the next decade, to approximately 3.3 million acres. USA Rice represents rice producers in the six largest rice-producing states of Arkansas, California, Louisiana, Mississippi, Missouri, and Texas.

Historically, rice production in the United States was connected to agriculture using enslaved labor in the American South, first planting African rice and other kinds of rice in the marsh areas of Georgia, South Carolina, and later in the Louisiana territory and Texas, frequently in southern plantations. For some regions, this became an important profitable cash crop during the 18th and 19th centuries. In the 20th century, rice production was introduced to California, Arkansas, and the Mississippi Delta in Louisiana. Contemporary rice production in the United States includes African, Asian, and native varieties from the Americas.

Micro-irrigation, also called Micro-spray,localized, low-volume, low-flow, or trickle irrigation, is an irrigation method with lower water pressure and flow than a traditional sprinkler system. Low-volume irrigation is used in agriculture for row crops, orchards, and vineyards. It is also used in horticulture in wholesale nurseries, in landscaping for civic, commercial, and private landscapes and gardens, and in the science and practice of restoration ecology and environmental remediation. The lower volume allows the water to be absorbed into slow-percolation soils such as clay, minimizing runoff.
