The invention relates to a culture soil with water absorption properties, comprising peat moss having fibers coated with a film of water-absorbing clay material. Such a culture soil is produced by a process comprising the steps of (a) subjecting water to a surface activation treatment; (b) suspending a water-absorbing clay material in the water obtained in step (a) to form an aqueous suspension of the clay material; (c) treating peat moss having water repellency when dried, with the aqueous suspension of clay material obtained in step (b) to thereby coat fibers of the peat moss with a film of the clay material; and (d) drying the coated peat moss fibers obtained in step (c). The culture soil of the invention is useful for growing seedlings and can be molded into a board to provide a seedling-growing peat board which is lightweight and easy to handle.
