According to Rule 5E-1.003, what is required for fertilizers used on urban turf or lawns?

The requirement for fertilizers used on urban turf or lawns, according to Rule 5E-1.003, emphasizes the need for either no phosphate or low phosphate content. This regulation addresses environmental concerns, particularly the risk of nutrient runoff causing water pollution, such as algal blooms in freshwater systems. By limiting phosphate levels in fertilizers, the rule aims to promote responsible lawn care practices that protect water quality while still allowing for healthy grass growth.

In contrast, high nitrogen content is not specifically mandated, nor is there a requirement for fertilizers to consist solely of organic ingredients or to utilize special packaging. Each of these alternatives may have their own benefits or applications in specific contexts, but they do not align directly with the specific regulations outlined in this rule.
