What is a main advantage of using coated soluble materials in fertilizers?

Using coated soluble materials in fertilizers provides the main advantage of slow nutrient release, which allows for a more controlled and prolonged feeding of plants. This slow release minimizes nutrient leaching and can help ensure that plants receive nutrients steadily over an extended period, matching their growth requirements more effectively. This method can lead to reduced nutrient loss to the environment and can improve overall fertilizer efficiency.

Additionally, the slow nutrient release helps in minimizing the likelihood of nutrient burn, which can occur when plants are exposed to high concentrations of nutrients at once. By stabilizing the nutrient delivery, coated fertilizers often improve the likelihood of optimal plant growth and yield while promoting sustainable agricultural practices.
