FAL'LOW, n.

1. Land that has lain a year or more untilled or unseeded. It is also called fallow when plowed without being sowed. The plowing of the fallows is a benefit to land. Mortimer.
2. The plowing or tilling of land, without sowing it, for a season. Summer fallow, properly conducted, has ever been found a sure method of destroying weeds. By a complete summer fallow, land is rendered tender and mellow. The fallow gives it a better tilth, than can be given by a fallow crop. Sinclair. A green fallow, in England, is that where land is rendered mellow and clean from weeds, by means of some green crop, as turneps, potatoes, &c. Cyc.
