Do you think a herd of about 20 cows will devistate 2 acres of clover and 2 acres of corn? The cows get fed hey every day and have aporox. 100 acres to roam the woods/fields. It' s newly aquired land and I have ideas with high hopes and serious doubts.

Hi-wall

They will destroy it in a matter of days. I know from exp. i run cows next to my hunting and use a hotwire to keep them in.

That plot would make a nice snack for 20 cows. Old pasture is not nearly as tempting as young clover to the cattle. An electric fence will keep them out. But; they' ll be in the plot as soon as the fence is turned off. The other pasture will be grazed out and your plot will be even more of a temptation.

Thanks you two for the replies! I figured so but was hoping the answer would be they would keep it low enough that I wouldn' t have to cut it.

So you guys are saying deer wouldn' t mind getting zapped!? Or say they will learn to jump in and not freek out and run to the next county after a few zaps?

What does a system like this run? Lets just figure on an acre as this is gettin to be a pain

Dan O.

A 3 ft. high electric fence to a deer is like you stepping over a garden hose on the grass. They hop my neighbours fence routinely. If you can get old posts (even 4 ft. rebar) the insulators, wire and battery operated unit should be about $100. A plug in unit is more expensive but you never need a battery (just a long extension cord) LOL.

Yeah in this case a couple thousand yds of cord Well I might write this section with the cows off. Don' t know how the farmer would feel about new fence. Down the road 1/4 mile is another partial with an abandon (un used) hay field. The hay is waist high. My guess is I have to mow it and kill it and till it and kill again and test and lime and fertilize and maybe next year have nice crop by this time. Don' t you just love new land!

Thanks for the help Dan!

Dan O.

If it' s clover or alfalfa hay, a few timely cuttings and an overseeding with clover in the spring might rejuvenate it. My bird' s foot trefoil is spreading like crazy where I mow the grass short. It' s thinning out in the field where it has to compete with the taller grass and there is less mowing.

The frequent mowings also keep the clover etc, more tender for the deer.

Dan O. Man O Man now you have me on the edge of my seat! How can I tell what kind of hay it is. All I know about hay around here is that it feeds local cows and horses.

So your saying I don' t have to start from scratch(bare soil) if it' s one of the two types of hay? I just mow it and sow away? How short and often do you mow?

Dan O.

Just look at the hay for alfalfa or clover. If it' s all grass you' ll be starting from almost scratch. If there' s 25%or more of clover/alfalfa you' ve got a good start. I' d mow every 4-6 weeks to keep the grass down. I' ll check the internet to see if I can find a site on pasture renovation for you.

Renovate Pastures to Increase Production at Lower Costs

Renovating pastures by introducing legumes into an existing grass field without plowing is not new. It has been around in some sections of the USA for at least 50 years. In other areas, it has been used very little simply because farmers either do not know it’s advantages or know how to go about the process. So here goes!

Why put legumes into grass fields when commercial nitrogen in the form or ammonium nitrate is so accessible? Mainly it’s a matter of better animal performance. Livestock just ‘do-better’ on the mixture than they do on straight grass. Research has shown and farmers have proven that an 8-12 pound seeding rate of red clover costs about a dollar a pound and will produce as much forage as $50-$65 invested in nitrogen (ammonium nitrate @ $220 per ton @ 150-200 pounds of N per acre). Also when legumes are added to grass, the production distribution is better throughout the spring, summer and fall grazing months than grass alone.

Pasture renovation improves conception rates as well as cattle gains. In an Illinois study, it was found that cow conception rates on grass and legume pastures was 89% compared to 75% on straight grass. And, the calves from these mixed pastures weighed an average 50 pounds more at weaning.

Renovation also produces more milk. In a Tennessee study, milk production increased 6 pounds per day or 1,800 pounds in a 305 day lactation period when grazing a clover-grass mix versus grass and nitrogen.

A study by Purdue University researchers puts the entire picture together when it comes to the beef cow-calf herd. Over a three-year period using 100 cows, the renovated pastures produced 20 more calves each year. All of the calves in the herd on the clover-grass pastures weighed 85 pounds heavier than the matched calves on pastures with grass and nitrogen. When the 20 more calves saved are added to the increased weights for all of the calves, that’s an additional 15,000 pounds more beef. At a dollar a pound for stockers today, it doesn’t take a rocket scientist to figure that’s $15000 more gross income from that 100 cow herd for a seed cost of $10-$12.

Renovating Grass Fields with Red Clover

Seeding clovers into cool season grass fields (tall fescue, orchardgrass, bluegrass, smooth bromegrass) is more successful in the early spring than in the fall. There are three basic systems: 1) with tillage 2) Tred-in and 3) with minimum or no tillage. All systems are explained below:.

1) When using the tillage system plant as early as possible! This provides earlier growth from competing weeds and kicks the early growth off to a great start.

Graze or mow the grass prior to renovation. This allows the tillage tools to penetrate the soil and leave a minimum deposit of trash so that the seed has a better chance for contact with the soil.
Test the soil and apply the needed lime, phosphate and potash. No Nitrogen!
Seed RedlanGraze red clover or Redland III at 10-12 pound rate. If you decide to include 1-2 pounds of white clover, you can reduce the red clover rate by 2 pounds per acre.
There are three systems of renovating that work well with clovers. Conventional System: With a field cultivator, tiller, or disc harrow, open 40-60% of the grass sod. This tillage can and should be done in the late fall or early winter so that early spring plantings are more feasible. If the soil is likely to erode because of slope and soil type, till on the contour. In the spring, smooth the ground and plant the clover seed.
2) The Tred-In Method: When fields are too hilly to mechanically till or if you want to reduce costs of renovating, this system works well. Confine a large population of livestock to a small acreage at a time so that the livestock can till the soil with their feet. When necessary, feed hay in areas that are somewhat isolated to get even tillage. Increase the seeding rate by 2-4 pounds and plant early and keep the cattle on the fields to ‘punch’ the seed in the soil.

3) Chemical renovation plus No-Till drill system: This is the new look. The use of Gramoxone plus surfactant or Roundup are great substitutes for tillage. The only differences are 1) the resident vegetation needs to be green for these chemicals to work so the plantings will be later. 2) the use of a no-till drill is necessary for best results. Very often, two sprays are necessary for best results. One can be applied in the fall while the vegetation is still green the second after green-up in the spring. Don’t bury the seed when you seed with the no-till drill! For more details on no-till seeding with herbicides, go to no-till seeding alfalfa in the Alfalfa Grazing Section in our web site.

Newly renovated fields should be grazed closely to keep the grass under control until the livestock start biting off the new legumes. Then remove them and allow the clover to establish (4-6 weeks). At that time, you can start grazing or mowing the fields to suit your program.
Grazing management is important when carrying capacity and returns are important. Rotational grazing that allows the livestock to take the clovers to 2-3 inches of top growth is ideal. Then, remove them to allow the legumes to recover.
Don’t forget to top-dress fertilize as needed. Let your soil tests determine what materials are needed and how much. In most sections (except the deep southern states) red clover will flourish for two years and in some regions, some farmers are able to get as much as three years from a planting. Experienced growers have formed a habit of over-seeding as the livestock are grazing early each spring. This practice helps to keep a viable stand of clover ‘coming-on’ every year so that renovating is not so imperative.
