There are two distinct kinds of rice

There are two distinct kinds of rice, upland rice and lowland rice. Upland rice demands in general the same methods of culture that are required by other cereals, for example, oats or wheat. The growing of lowland rice is considerably more difficult and includes the necessity of flooding the fields with water at proper times.

A stiff, half-clay soil with some loam is best suited to this crop. The soil should have a clay subsoil to retain water and to give stiffness enough to allow the use of harvesting-machinery. Some good rice soils are so stiff that they must be flooded to soften them enough to admit of plowing. Plow deeply to give the roots ample feeding-space. Good tillage, which is too often neglected, is valuable.
