Under the new law, when can phosphorus be applied for turf maintenance?

Phosphorus application for turf maintenance under the new law is permitted only if a soil test indicates the need. This aligns with the best management practices aimed at minimizing environmental impacts, particularly in preventing nutrient runoff into waterways. Soil tests provide precise information about nutrient levels in the soil, allowing for a more targeted and responsible approach to fertilization.

Using soil testing as a prerequisite ensures that phosphorus is only applied when necessary, promoting both plant health and environmental protection. This method reduces the chances of over-fertilization, which can lead to issues such as algal blooms in nearby water bodies due to excess phosphorus.

Other potential scenarios, such as applying phosphorus anytime during the growing season, during drought periods, or only using slow-release fertilizers, do not take into account the specific nutrient needs determined by soil testing. Thus, they do not conform to the regulations set forth by the law aimed at sustainable turf management.
