Improvements relating to soluble powder prescription fertiliser compositions incorporating special soil test systems

摘要

The object of the invention provides a new technique of soil nutrient analysis using a photo-colourmetric determination system. The manufacture of soluble powdered chemical fertiliser containing certain protective chemicals ensures that all the chemicals are utilised by plants, protozoa life, bacteria and fungi and subsequently the animals eating produce grown in the soil. Prevention by use of the protective chemicals of the fertiliser chemicals being available for surface run-off, leaching and fixation. A prescribed protected chemical fertiliser will replace determined deficient chemicals in the soil providing sufficient balanced nutrients for crop or pastures needs in the next growing season. A controlled means of applying with the protected prescription fertilisers fungicides, herbicides, hormones, insecticides, medicines and/or antibiotics, vitamins or weedicides. Included in the prescription fertiliser are protective chemicals having channel-lattice properties which are either foods or fertiliser protecting the powdered fertiliser's organic and inorganic chemicals from reaction by humid conditions.
