Please note the following: 
Nitrogen (N) is not directly measured in this type of soil test despite being an essential macronutrient. As a dynamic nutrient with various pathways of movement, N content changes quickly; accurate testing requires immediate freezing and is an expensive process. Therefore, N recommendations are based on multiple calculations that consider soil fertility research, your soil’s organic matter content, your cropping history, and the next crop needs. Make sure to contact your local office ahead of time, as tests are often out of stock during periods of high demand.
