What do you call a slow, soluble, synthetic fertilizer?

Fertilizer Analysis
Urea-formaldehyde
Leaching
Complete Fertilizer

The correct answer is: Urea-formaldehyde

A slow, soluble, synthetic fertilizer is a type of fertilizer that has a slower release of nutrients into the soil and is composed of synthetic materials. It is designed to gradually provide plants with the necessary nutrients over an extended period of time. It is also able to dissolve in water, making it easier for plants to absorb the nutrients. Out of the given options, only option B, Urea-formaldehyde, fits this definition. Fertilizer Analysis (option A) refers to the process of analyzing fertilizer components, not a specific type. Leaching (option C) is a method of washing out nutrients from the soil, not a type of fertilizer. Complete Fertilizer (option D) is a type of fertilizer that contains a balanced ratio of the three main nutrients (nitrogen, phosphorus, and potassium) but does not necessarily fit the description of a slow, soluble, synthetic fertilizer. Therefore, option B is the most appropriate choice.
