Abstract: A modular soil conserving planter constitutes a longitudinal trough having open transverse end faces, the trough including a lower horizontal grate and an upper horizontal grate, each of such grates extending along substantially the longitudinal length of the trough, the lower grate defining a drainage grate and the upper grate defining a soil retention grate, a region of the trough beneath the drainage grate including apertures for control of drainage from the trough, in which longitudinal ends of the trough. Each longitudinal end of the trough further include means for selectable connections to open end faces of adjoining like planters.

Abstract: A modular soil conserving planter is definable in terms of a longitudinal trough having open transverse end faces and longitudinal side walls which are axially compressible, laterally flexible integral accordion-like surface, the surface including elements for control of drainage from the trough and each end face of the trough further including snap-fittable selectable connections to open end faces of adjoining like planters. In the bottommost region of the planter are provided drainage openings which control the rate at which water can escape from the planter through the effect of gravity and of osmosis from the surrounding soil.
