What term describes the portion of a fertilizer that easily dissolves in water?

Water soluble
Slow release
Granular
Insoluble

The correct answer is: Water soluble

The term that describes the portion of fertilizer that easily dissolves in water is water soluble. Water-soluble fertilizers are designed to dissolve quickly in water, allowing for immediate availability of nutrients to plants upon application. This characteristic is particularly important for nutrient uptake because it ensures that the essential elements are accessible when plants need them most, especially during critical growth stages. The rapid dissolution also facilitates methods like fertigation, where nutrients are applied through irrigation, promoting efficient nutrient use and minimizing losses to the environment. This high availability of nutrients makes water-soluble fertilizers very effective, particularly for crops with high nutrient demands or in situations where a quick response is necessary.
