True or False: Nitrogen levels are required to be included in soil test results.

Soil test results typically include values for various nutrients like phosphorus, potassium, pH, and organic matter, but nitrogen levels are not routinely included. This is due to the transient nature of nitrogen in the soil; it can quickly change forms and is often subject to leaching, volatilization, and microbial activity. As a result, while nitrogen is critically important for plant growth, soil tests usually measure it indirectly or recommend using specific methods to assess nitrogen levels, often tied to the needs of the crop rather than standard values provided in all soil tests.

In practice, nitrogen recommendations are frequently based on crop needs and previous soil management practices rather than direct nitrogen test results from every soil sample. Consequently, having nitrogen levels reported is not a standard requirement for all soil tests across the board, which is why the assertion that nitrogen must be included in soil test results is considered false.
