Abstract: The invention pertains to a compound used as a soil additive to enhance farming, forestry, ornamental and landscaping production in conditions of droughts and insufficient fertile soils. This composition contains potassium based absorbent acrylamide crossed linked copolymers, together with nutritional elements of fast and slow solubility, derived from mineral and organic substances, including in some cases, extracts from sea kelp as growth stimulants. This soil additive is used in varied dosages according to the type of crop, soil and climate. In field tests it has demonstrated great efficiency in enhancing crop production and/or higher quality crops and/or larger bloom and/or saving of irrigation water.
