| 170 | Granulated fertilizer composed of micronutrients and clay | US10530222 | 2002-10-16 | US08017158B2 | 2011-09-13 | Jose Luis Miranda Valencia; Gustavo Rebora Gonzalez |
| The invention consists of a granulated fertilizer which contains iron (11 to 13%), zinc (3 to 9%), manganese (0.1 to 2.5%), copper (0.5 to 0.7%), in the form of sulphates, also ammonium molybdate (0 to 0.1%) and a Caolinite, Illite or Montmorillonite clay (45 to 57%), or a mixture of them in any proportion. All the percentages by weight are based on the total weight of the fertilizer. The product is 100% soluble, the high cationic exchange capacity which clays have allows the micronutrients to be adsorbed by the clay and prevent its leaching or reacting, making its assimilation by the plant more efficient and better. The use of sulphates in the soil, in the presence of water provoks an acidification of the soil which allows a better assimilation of the micronutrients in alkaline soils. | ||||||

| 175 | Wet granulation method for generating granules | US10252973 | 2002-09-24 | US06805821B2 | 2004-10-19 | Robin Phinney |
| A method of wet granulation of fertilizer and other materials into granules. The method involves formation of the granule directly on the pan from the feedstock without intermediate steps or the use of seed materials. The result is a product having a completely uniform cross section. The feedstock is initially in the size distribution of −150 mesh with 90% or greater in the size range of 200 mesh. Moisture is maintained to facilitate a steady process without cycling. The method has the advantage of allowing granulation of materials either known to be hazardous or inherently difficult to granulate in a safe and expedient manner. The process permits the formation of multiple feedstock granules. The initial feedstock may be augmented with a different feedstock in a second pan having a different composition and size from the initial feedstock. | ||||||
