Abstract
There is disclosed an agricultural mulch in sheet form pierced by a recurring, closely spaced slit pattern which provides normally closed passage points between the open air and ground at any random point in the growing area for germinating plants and rain water. The slit pattern can provide structural integrity for the sheet laterally, longitudinally, diagonally or various combinations thereof, and can additionally provide flaps which can be oriented to protect the emergent plants from cold winds.
