Kindersley Sk. | Wow that is some really good detailed testing, you sure have my curiosity peaked now. Have you ever noticed changes in the ratio between NO3 and depth. In other words, is the highest NO3 test always the 3ft depth or does it change depending on previous crop, or other factors? And from year to year is there ever any big swings in NO3 results in the deeper samples.
edit. I thought of another question. Is the water the test refers to a measure of, plant available moisture or total moisture.
