What is the maximum water-soluble nitrogen limit for fertilizer application per 1,000 square feet?

The maximum water-soluble nitrogen limit for fertilizer application per 1,000 square feet being 0.7 lb is based on guidelines aimed at minimizing the potential for nitrogen leaching into waterways. This limit is established to regulate the amount of nitrogen that can be applied in a single application to promote sustainable agricultural practices while reducing environmental impact.

By adhering to this limit, fertilizer applicators can ensure that nutrients are effectively utilized by plants with minimal runoff entering water sources. A lower application rate helps reduce the risk of over-fertilization, which can lead to nutrient pollution in aquatic systems. This standard is part of best management practices in agronomy that aim to balance agricultural production needs with environmental stewardship.
