Do you need to add lime and fertilizer to a winter rye planting?
No...rye will grow on almost any soil and PH levels, however it is a great time to start correcting soil nutrient problems for the next crops by applying lime, P&K per soil testing.
Should I use nitrogen tilled in at planting?
That depends on how intense you feel grazing will be and time of planting. Applying nitrogen can cause more harm then good by encouraging rapid growth that will leave winter rye (or any cereal) to tall, stemmy and unpalatable by late hunting season.
Use 40-80#'s of actual nitrogen per acre only if...
1) You expect heavy grazing and need to encourage growth to keep up with it
2) You plant late and want the rye to grow rapidly to catch up before cold weather
I fertilized with 200#'s of urea on the right, 100#'s in the middle and zero on the left in this pic and you can see that it is greener on the right.
Will deer prefer areas I fertilize?
On three different farms...deer eat the rye with and without nitrogen equally
No nitrogen....
200#'s of urea applied at planting
Should I topdress additional nitrogen to "sweeten" the rye?
Topdressing will not make the rye any "sweeter" then adding nitrogen at planting and because rye (or any fall grains) are in the ground a short time before cold weather it makes little sense to add additional nitrogen.
Top dressing nitrogen is risky when using urea, without rain it will quickly be lost and all forms of nitrogen need rain to push it to root depth so if you need N the least risk option is to apply it at planting time.
If you find that your rye is being hammered hard and you need addtional growth then apply nitrogen just before a rain but adding it is not going to attract more/bigger/better deer then already feed there.
How late can I plant rye?
Rye will germinate at 34 dgrees and grow at 38 degrees but a minimum of 3 weeks of growing weather is usually required to have enough growth for the rye to be attractive to deer. Weather of course plays a huge influence on the actual growth of winter rye but generally by this time one has little to lose by sowing rye.
I planted 2 more acres on September 29th and expect to have very good growth yet this fall.
This is 30 days of winter rye and pea growth after 3 weeks with not a drop of rain.
Can I really just broadcast winter rye onto untilled soil and actually have it germinate and grow??
Absoutely!
Two things are required...soil/seed contact and rain! Without rain the seed will just lay there until it gets moisture but once it does rain (or the soil is already moist) the seed will quickly germinate and grow.
I over seeded this rye about 10 days ago into some heavily grazed brassicas...
Into some field peas
and just bare soil
Nothing could be easier then overseeding winter rye into standing crops such as soybeans, corn, thin or heavily grazed brassicas, beets, peas, milo...the list is endless!
It will not work to overseed rye into brassicas or soybeans that are tall and have a heavy canopy. Soys will eventually drop leaves but brassicas will remain standing until to late for the rye to grow.
Overseed winter rye at 100-150#'s per acre as close to a rain as possible although it will just lay there until it does rain.
Red clover can be added to the rye to overseed into standing soybeans as well...
