Abstract:
A biodegradable plant protector and growth enhancement device comprising, in combination:(a) a first layer of weblike first material having a plurality of passages which permit the passage of air and water therethrough but are sufficiently small to prevent the passage of sandlike granular material, said first material being capable of naturally biodegrading when placed in the soil;(b) a second layer of loose, granular second material for enhancing plant growth, said second layer being porous to air and water and being capable of naturally biodegrading when placed in the soil;(c) a third layer of weblike third material having a plurality of passages which permit the passage of air and water therethrough but are sufficiently small to prevent the passage of sandlike granular material, said third material being capable of naturally biodegrading when placed in the soil;wherein said first and third layers are connected together and form a sandwich-like mat with the second layer between them;whereby said mat is adapted to be placed on or in the soil adjacent to a plant to protect the plant and enhance its growth.
