Today marked the last day of my experiment with rotatilling, pneumatic drilling/harrowing, and grazing annuals as part of a pasture improvement scheme.
Grazing comparison data is as follows:
2013-2014 – Paddock 22 – 3218 lbs, Paddock 23 – 1871 lbs Total: 5089 lbs
2014-2015 – Paddock 22 – 3567 lbs, Paddock 23 – 2007 lbs Total: 5574 lbs
2015-2016 – Paddock 22 – 2072 lbs, Paddock 23 – 1222 lbs Total: 3294 lbs
2016-2017 – lost all my records
2017-2018 – Paddock 22 – 1547 lbs, Paddock 23 – 695 lbs Total: 2242 lbs
As you can imagine, i was shocked at the lack of grazing days provided by the annuals, but this was my first experience. When i turned them in on the annuals, the cows and calves grazed it all down in four days! In a few days, i was able to turn them back in for a couple more days grazing to boost that yield just a bit. However, at this point, the paddocks will take a very long rest. One thing i did not observe and record in previous years and that is cow condition. At least for this year, these cows were slick and shiny healthy coming off the annuals, but they were that way going in, too. So…..
So, in a nutshell, it cost me a total of $1842.12 to plant 18 acres of annuals for grazing. The purpose of annuals to help rejuvenate the soil microbe community and not necessarily for gain in grazing. Good thing, because it certainly failed in that department. However, as i had written before, the goal is to eradicate toxic fescue and build organic matter. It does look like that has happened at least in short term. It is very hard to measure long term benefits. However, from this point, i’m planning to tack the sail and switch to tilling then no-till a permanent ley (grassland). Whether or not that will work remains to be seen, but i’m keen to find a way to reduce then eliminate any tractor work. I hope to get that scheme underway and perhaps even completed this week. This new scheme, although i do plan to till before planting to permanent ley, will provide a side by side comparison of planting annuals first vs planting permanent pasture once and done. There will be a few spots, too, that won’t be tilled and seeds will be drilled straight into established pasture.
