A growing medium comprising fibrous tree bark and fibrous wood components, wherein the fibers of the growing medium have an average length to width ratio, such that the growing medium has a dry bulk density of about 60 kg/m.sup.3 or lower and wet bulk density of about 120 kg/m.sup.3 or lower.

A composition includes a plurality of processed leguminous straw particles having about 18-21 wt. % of particles on sieve #25 or particles measuring 0.71-1.17 mm and about 18-20 wt. % of particles on sieve #50 or particles measuring 0.3-0.7 mm, based on total weight of the leguminous straw particles, the composition being a mulch composition.

Processes capable of producing bulk materials suitable for use by the horticulture industry, resulting bulk materials produced thereby, and applications for these processes and materials. Preferred bulk materials have physical properties similar to peat moss and comprise individual materials, each at least partially having a twisted, curled, clumped and rolled structure. The individual materials may further comprise small granular particles dispersed throughout the twisted, curled, clumped and rolled structure. The individual materials may be rolled fibers such that the bulk material has physical properties similar to sphagnum peat moss so as to be particularly suitable as, for example, a soil conditioner, an absorbent material, a chemical carrier, or a filtering material. Alternatively, the individual materials may be rolled particles such that the bulk material has physical properties similar to milled peat moss so as to be particularly suitable as propagation media.

Disclosed is a liquid mulching agent composition, which is environmentally friendly due to use of seaweed, facilitates soil coating, and has high light blocking efficiency, making it possible to control heat retention and water content in the soil. The liquid mulching agent composition includes a seaweed extract, a first component including at least one selected from the group consisting of humic acid, fulvic acid, and charcoal, and a second component including at least one selected from the group consisting of sodium alginate, polyvinyl alcohol, keratin, and sodium silicate.
