Course Spotlight. As a marine biology major, youâll most likely take a course in marine ecology. In this class, youâll focus less on the details of individual organisms and more on their relationships with each other and with their habitats.
The different types of chemical fertilizers are usually classified according to the three principal elements, namely Nitrogen (N) , Phosphorous (P) and Potassium (K) , and may, therefore, be included in more than one group. Liquid fertilizers : â these types of fertilizer come in a variety of formulations and even include organic fertilizer, complete fertilizer as well as special purpose fertilizer. 2  Some examples of liquid fertilizer are Nitrosol and African Violet Food.
Super and Triple Super. Super phosphate fertilizers come in two common forms: single super phosphate and triple super phosphate. Both are manufactured by reacting insoluble mineral phosphate with acid to create a soluble, readily available form of phosphate.ll synthetic phosphorus fertilizers are made from mined rock phosphate. Phosphorus is one of the three primary plant nutrients. Fertilizers often supply significant amounts of phosphorus, along with nitrogen and potassium, the other two primary nutrients.
