Annuals Scheme – Final Analysis

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.

I drive through the annuals with my Gator to make it easier to set up a polybraid fence through it.

Grazed part next to ungrazed annuals.  That tall stuff still standing in common ragweed.

My ground is very poor in most areas and this is all it will grow in a 65 day period of the annuals.

This is along the fence line (see fence on the left).  What a difference in where i tilled and planted vs undisturbed.  The ubiquitous Kansas ragweed (lanceleaf) is still thriving where it is undisturbed.

Those cows didn’t waste any.  They really, really enjoyed eating the succulent annuals and snarfed down the volunteer yellow foxtail.  The stalks are trampled nicely.

Cows on the Annuals

It's been a rather busy and momentous month, so i'm way behind on reporting on the annuals for grazing and pasture improvement project.  Here are photos of growth at 60 days.  Turned the cows in on August 1, 2017.  Yah willing, my final report will be coming soon.  It will take some number crunching and analysis, so will be several days, but i'm ready to put paid to this project.
