Which type of fertilizer contains a higher amount of potassium compared to nitrogen or phosphorus?

The correct choice indicates a type of fertilizer specifically designed to provide a higher concentration of potassium, which is essential for plant health and growth. Potassium plays a crucial role in various plant processes, including water regulation, enzyme activation, and photosynthesis.

Potassic fertilizers are formulated primarily to supply potassium, which is indicated by a higher percentage of the macronutrient in their composition. They are particularly beneficial for crops that require significant potassium inputs for optimal yield and quality. This distinguishes them from nitrogenous fertilizers, which have a predominant focus on nitrogen, and phosphatic fertilizers, which primarily supply phosphorus. Complete fertilizers may contain a balanced ratio of nitrogen, phosphorus, and potassium, but they do not have a higher concentration of potassium compared to the other nutrients.

Understanding the role and composition of various fertilizers helps farmers and agricultural professionals to make informed decisions about nutrient management to enhance crop productivity.
