What percentage does "% Slowly Available Water Soluble Nitrogen" indicate?

The designation "% Slowly Available Water Soluble Nitrogen" refers to the specific fraction of nitrogen in a fertilizer that is released gradually and is soluble in water. This is significant for understanding how the nitrogen will be available to plants over time. Unlike immediately available nitrogen, which can be quickly taken up by plants, slowly available nitrogen helps to ensure that the plants receive a steady supply of this essential nutrient without the risk of leaching or volatilization.

This gradual release is particularly beneficial in preventing nutrient runoff into waterways and providing a more sustained feeding for plants, effectively matching their growth rates and reducing the frequency of fertilizer applications. Understanding this concept is crucial for effective soil and nutrient management in agricultural practices. The other choices either misinterpret the definition or focus on different aspects of nitrogen content that do not pertain to the slowly available soluble fraction.
