* the three secondary macronutrients: calcium (Ca), sulphur (S), magnesium (Mg).
* and the micronutrients or trace minerals: boron (B), chlorine (Cl), manganese (Mn), iron (Fe), zinc (Zn), copper (Cu), molybdenum (Mo) and selenium (Se).
The macronutrients are consumed in larger quantities and are present in plant tissue in quantities from 0.2% to 4.0% (on a dry matter weight basis). Micronutrients are consumed in smaller quantities and are present in plant tissue in quantities measured in parts per million (ppm), ranging from 5 to 200 ppm, or less than 0.02% dry weight.
Rock phosphate: Let us explain a little more of the raw material product which form the core of our current
interests. This material is mined from the regions having large deposits, carried by surface transport to the nearest port and despatched world wide through the sea. The phosphate contained in the rock is of great importance to plants and agriculture. 
Riches from the earth
The grades that could be organised range from 18 % purity onwards for specific applications. Some source origins go up to 37 % purity. The most sought after being in the range of 28 %, 30 % etc. Availability of rock worldwide is limited to certain regions, logistic cost is another important factor in the delivered pricing. Surely pricing is influenced due to location, purity, and a host of other parameters.
