Final answer:
Slow release and water insoluble refer to fertilizers that dissolve over time. Multi nutrient fertilizers provide two or more nutrients, with MAP and DAP being common NP fertilizers. Organic fertilizers from living materials often contain additional nutrient-rich additives.
Step-by-step explanation:
The notion that slow release and water insoluble are synonymous refers to the characteristic of certain fertilizer components that are designed to dissolve slowly over time, as opposed to quick-release, water-soluble fertilizers. Multinutrient or multi nutrient fertilizers commonly contain essential plant nutrients, including nitrogen (N), phosphorus (P), and potassium (K). Binary fertilizers such as NP, NK, and PK provide two main nutrients to plants, with MAP and DAP being popular examples of NP fertilizers. Organic fertilizers, derived from living or formerly living materials, are often marketed as "organic fertilizer" and contain a mix of organic materials and acceptable additives. It's also key to understand that fertilizers applied to lawns and gardens may contribute to water pollution via surface run-off or groundwater movement.
