ABSTRACT:
Disclosed herein is agricultural paper to be made into pots for raising seedlings. It is made up of a first layer made chiefly of natural pulp and a second layer made of synthetic fibers having a basis weight of 3-15 g/m.sup.2, said first layer and second layer being joined to each other by the wet papermaking process which intertwines the fibers of the two layers at their joining interface. The second layer is formed by fusion bonding composite synthetic fibers of polymers having different plasticizing temperatures.
