A compressed horticultural slab includes a substrate including a plurality of fibers compressed in a volume ratio of initial to compressed fiber of 1:4 to 1:60, the plurality of fibers having a shape of the slab, a first set of dimensions when the substrate has a moisture content of up to about 20 to 25 wt. % and a second set of dimensions when the moisture content increases above about 20 to 25 wt. %, based on the total weight of the substrate, the second set of dimensions having greater values than the first set of dimensions.

A fluid retention compound and more specifically, but not exclusively, a fluid retention compound for use in agriculture, mining and construction. Retention of water using moisture absorbers is known in the art and used to improve the water-holding capacity of various media. A problem with existing moisture absorbers is the relatively ineffective rate at which water is retained and nutrients absorbed. In accordance with the invention there is provided a fluid retention compound including a superabsorbent polymer, an adsorbent, and a pH modifier. It is envisaged that the invention will provide a fluid retention compound which increases the efficacy of its water holding capacity, nutrient uptake and adsorption of other substances.
