The county agent....YES WE HAVE THEM...along with the feed store guy, and the local "young farmers" fella........Don't know if you have a place where all the good ol boys go for their coffee, biscuits and gravy, and mainly gossip.......Anyway, I got mixed answers about the wet soil absorbing the NIT. It makes sense as if you put some fert on the concrete floor, within a few hours you see wet stains and then the stuff goes away............So, that is evaporation happening, and is it sucking into water saturated soil?.....That is the chance one takes. A for sure opinion is that NIT goes into the soil and stays there for 45 days. Yes, the first two weeks or so is the best. So, If one puts down the fert a bit later like you suggest, that would be the best thing for the young plants............
Watching the weather so one can time the WHEN is the tricky part for me. A couple of years ago got my seed down and it rained just right......Then I was ready to put the fert down and NO rain......April that year was totally dry and then when it finally started raining the seedlings were mostly gone and it was to late in the season to get seed down...........
Max, you mentioned drilling. Wish I could as with the trees and hills, I end up using a harrow of one type or another.....Not doing that this year as I have a good result from the fall seeding and don't want to destroy them, so am gonna just overseed........
What I have had best results with is using straw mulch goat poop from the barn/sheds where the goats overnight and stay on rainy days.........Spread that out over an eroded hillside where water control up slope got out of hand due to the HEAVY rains this year..........Most often this is put in a pile and used as a fert mix on the garden, shrubs, and lawn seed projects........IT GROWS......Enough....I talk way to much.....God bless......Dennis
