Abstract
Abstract A perforate member is laid over a windrow of cut plants to confine it against the action of the wind. The member is open over a major portion of its area to sunlight and the passage of air. The member is held against the ground preferably by the weight of water in flexible tubes extending along opposite sides of the windrow.
