Title: Worthless Nitrogen Reading in Clay Soil
Review: We have clay soil that's amended with compost and manure. We found the test kit was easy enough to use but it gave us a zero nitrogen reading. So we further amended the soil and it did not improve. So we put a nitrogen granule in the test water and it still read zero. After 48 hours the water remains cloudy so this might affect the readings but I can't really trust any reading.
