The method generally comprisess the steps of generating, analyzing a spatial database and devising a recipe. Generation of the spatial database involves the generation of both historic statements (110) and facts gathered from historic (112), present and future predicted events (114). Once the spatial database is generated, the facts are iteratively analyzed against the current statements (104) to see if they can or cannot be executed. If the facts can be executed, the facts are maintained as stored facts and analyzed for their economic feasibility. The determination of economic feasibility for the stored facts is accomplished by a iterative process similar to the determination of whether the facts can be executed. Once economic feasibility is determined, the recipe is devised. The method is optionally applied to the agricultural field for devising the fertilizer recipe, the irrigation recipe, and the split recipe.
