Macracote is a spherical granule of gold, compounded Controlled Slow Release Fertiliser with a diameter of 2 to 4mm. This is manufactured by coating granular NPK with a polymer composition of modified wax, natural additives and with trace elements.
Macracote range with various nutrient compositions and varying release rates are manufactured that meet the fertilisation requirements of many kinds of plants. As the release rates of the nutrients are accurately controlled by a blend of special coating technology, one single dose application is possible for the entire fertilisation to the plants, adjusting the rate of release to match the plant growth throughout the required period.
The controlled release of plant nutrients from Macracote fertilisers is a physical process, consisting of three steps;
Water penetration through its coating
Nutrients dissolving in the water within the coated granule
The release of nutrients in solution, through the unique coating which is in the form of a semi permeable membrane by the reverse osmotic pressure of the penetrating water.
 
The release of nutrients from Macracote is not influenced by microbial activity but is highly dependent on soil temperature variance.
Macracote technology is unique and differentiated in that the release of all the nutrients through the coating is simultaneous and at an even rate irrespective of the varying molecule sizes of N,P and K. This is due to the unique crystalline structure and morphology of its modified coating.
