What rhymes with Subirrigation?
subir·ri·ga·tion

In agriculture, subirrigation, also known as seepage irrigation, is a method of irrigation where water is delivered to the plant root zone from below the soil surface and absorbed upwards. The excess may be collected for reuse. Subirrigation is used in growing field crops such as tomatoes, peppers, and sugar cane in areas with high water tables such as Florida and in commercial greenhouse operations. Three basic types of subirrigation system are in general use for potted plants in greenhouses: ebb-and-flow; trough; and flooded floor. Greenhouse subirrigation has been growing in popularity since the 1990s. Advantages are water and nutrient conservation, and labor-saving. The outfitting cost is relatively high. Potential problems, such as the possibility of increased presence of disease in recycle water, have only begun to be investigated.
