Don’t seed or fertilize anything. Buy a couple of OBriens reels, poly wire and step in pigtails (Kencove Fence) and a good solar fencer. Max investment $1,600.00, utilize high stock density grazing to get this 10 year dormant grass back in shape.
You don’t need fertilizer if your grazing properly with daily moves allowing for the required amount of rest. 30 days is not enough rest, your going to run out of grass. A 30 day rotation is fine for one turn, but then every subsequent turn after that will get faster. Meaning your grass was not rested enough to re-graze. You eventually exhaust the root reserves and its just like driving a truck 50 miles a day and only putting in enough gas for 30 miles of driving at the end of each day. Its only a matter of time and your going to be out of gas, The grass is the same way, its fuel tank (root reserves) must be refueled to full capacity before you return to graze again or your going to run out of grass.
You will likely have lots of waste (trampled grass) in this 10 year dormant grass, that should not be viewed as a problem. That trampled grass is what feeds the mini critters in the soil, and they are needed to recycle all the manure urine and trampled grass back into new vigorous grass growth naturally. Fertilizers Herbicides, Insecticides all work against the soil microbes and drastically reduce the presence of Earth Worms as well. Cows, grass and fencing to control their grazing is all you need.
And here is the hardest part, put all the seed fertilizer herbicide and equipment money in the bank and leave it there. You can not buy your way to prosperity. The best place you can spend money is by buying a good style cafeteria mineral feeder and keep it stocked with the 11 different minerals (less than $200,00 worth of minerals) keep it supplied as they consume the minerals. It will change often as far as what they need.
Then stand back and let the Cows do the work for you. The goal is to extend the grazing season as long as you can. It gets better in time as your learning curve progresses. Spend time observing your stock, what they are doing and what is happening in your grass as it improves.
Clovers will come back naturally as will other grasses that may not be there now. Every day you don’t feed hay is like putting those dollars directly into your pocket. Those Canadian Thistles are like Candy to a Cow, mine eat them to the ground, high Calcium makes them a treat to a Cows appetite.
The seed bank is already in the soil it just needs hoof action to kick it into the growth mode. If bragging rights are important to you then you should be warned the learning curve is not straight up. The learning curve is actually an inverse curve, you will make mistakes, its sort of like jumping off a cliff. But hang in there and be brave because most people bail out just before they would have started to make some noticeable gains at the bottom of the learning curve.
With persistence and some self discipline you will be a winner. Just let the Cows do their thing they will show you how its done. Fence control, proper rest of the grass with water and minerals are all you need. All else is just like recreational tillage. There is nothing so useless as doing efficiently that which should not be done at all “Pete Drucker”
If you have problems or questions as you progress let me know, there is usually a simple solution to any problems that arise. E-mail is good, and good luck with the grazing, don’t let anybody convince you it will never work!! Prove them wrong
