i am going to have my soil tested in early spring and try to correct some inbalances before planting time. my question is with the nitrogen level difference from the time i test to the time i plant. i added calcium nitrate to the patch in late december more for calcium reasons than for the nitrogen. if my soil test in late winter/early spring shows higher than desirable nitrogen readings, do i assume that the level will become more desirable by planting time? also, if the nitrogen level looks good at the soil test, should i assume that come planting time i might be a little lighter on the nitrogen as the soil heats up and ntrogen in the nitratem form gets released? and ultimately, the most important thing would be my nitrogen levels at pollinating time to not be excessive for healthy fruit reasons?
i applied 100 lbs evenly in 2500 sq ft. i know i should have done more research and asked advice prior to the application, but i had i great spell of weather and started to apply it along with 4 inches of mushroom compost and before i knew it both 50 lb bags were spread. after doing some recent research, i definately have my concerns.
any advice is again greatly appreciated. shazzy

Won't all the chemical nitro leach away with snow and spring rain? We side dress our field corn instead broadcasting at planting so we don't lose the nitro by the time its needed. But I'm no expert..... I also have sandy soil witch is prone to leaching.

Number 1 Pumpkins do not need alot of nitrogen. The NH growers will tell you that. Number 2 The calcium is more important than the nitrogen in that product. Number 3 Yes, much of the nitrogen will leach out by spring. It is best to apply Cal-Nitrate in the Spring.

Most labs don't test for Nitrogen by chemical extraction. Rather if an N quantity is reorted, it is an estimate based on the percent Organic Matter.
Before having the soil tested again, call the lab & speak with them regarding their Nitrogen test protocol. Be sure also to explain what has been applied & when.
In the future, when applying large amounts of Calcium in the fall, reach for a bag of Gypsum. Calcium Nitrate is fine for light early spring N pushes & inseason tweaking. But not a first choice for heavy duty corrections.
