[QUOTE="Auggie, post: 157601, member: 237"] Leaching can happen. That is dependent on moisture and texture. Denitrification is another nitrogen loss pathway. 1-3%/day of your nitrogen will be lost to the atmosphere after 3 days of saturation. This is caused by anoxic bacteria. So denitrification is minimal in the spring since the soils are so cold. You can soil test. NDSU, Ag Soil Science (Minot) and AGVISE (Northwood) are certified testing labs. I recently completed a study where I compared NDSU soil test results with various kits purchased from a few different retailers. Those kits are OK for pH and nitrogen, but not very accurate for phosphorus and potassium. I just submitted a poster on this for a national meeting (below) Also, on Monday evening for the next few weeks, NDSU Extension is hosting a state wide gardening forum. It started last week. I'll be talking about soil testing next week. [ATTACH=CONFIG]34098._xfImport[/ATTACH] [/QUOTE]
