Jess has about 35 of 70 acres of brassicas planted, July 30th we received a whopping 4" of rain and the least we have heard of was 2.5" so while "to wet to plant" is rare in July...such is the case this year.
Regardless if you plant by hand and use a cultipacker or have a drill with packer wheels make sure soil is not sticking to packer wheels when planting...this is borderline and many fields need another day to dry out.
Previous to that soils were dry and having tilled in fertilizer and cultipacker followed tiller...Jess went to work drilling 10#'s per acre of PTT, DER and FT using the small seed box set on 45/50
The forage radish is slightly bigger and in our mix is planted at 5# per acre
Dwarf Essex Rape at 2.5#
and Purple Top Turnips at 2.5#
Brassica seed like clover seed should be planted 1/8-1/4" deep so it's imperative to pack first, broadcast or drill seed then re-pack. In our case the small seed box drops seeds right in front of packer wheels, well behind the disc openers where large seeds are dropped and the packer wheels lightly cover/press seeds into top 1/4" of soil.
If you have a conventional drill without a small seed box, tiny seeds may get buried to deep in which case broadcast seeds rather then drill.
10# per acre is upper limit and appropriate for heavy grazing IF accompanied by high nutrient levels, especially nitrogen so use common sense in regards to seeding rates if you have poor, dry soils, low/poor nutrient levels and/or few deer
Plant ALL in one plot in strips or blocks
Alice, Kopu II, Durana (or comparable) white clover 10% of plot, sow at 6#'s per acre with the rye combination in the fall or in the spring with oats and berseem clover. Correct Ph and P&K with soil tests
Brassicas in 45% of plot
Purple Top Turnips 2.5#
Dwarf Essex Rape 2.5#
GroundHog Forage radish 5#
Plant in mid to late July in most Midwest states, or 60-90 days before your first killing frost, Use 200#'s of 46-0-0 urea and 400#'s of 6-28-28 per acre. Follow the dead brassicas with oats and berseem or crimson clover in mid spring at 50#'s oats and 12-15#'s berseem clover an/or same of crimson clover and/or 50#'s of chickling vetch)
Cereal Grain combo in 45% of plot...I use 50# each rye, oats and peas along with radish and clover seed all plant in half of each feeding area
I use 50#'s each of the following:
Winter rye 50-80#'s per acre (56#'s = a bushel)
Spring oats 50-120#'s per acre (32#'s = a bushel)
Frostmaster Winter Peas or 4010/6040 Forage peas 20-80#'s per acre
Red Clover 8-12#'s per acre or white clover at 6#'s per acre (or 20-40 pounds hairy vetch and 20-30#'s crimson clover on sandy soils)
Groundhog Forage Radish 5#'s per acre
Plant in late August to early September, if following well fertilized brassicas use 100 - 200#'s of urea, if starting a new plot add 400#'s of 6-28-28 but for best results soil test and add only what is necessary.
Rotate the brassicas and rye combo each year
