Revisiting the pasture

I have irrigation water coming on tomorrow morning at 7 a.m.  (It comes through Solano Irrigation District and I have to call when I want the water "on"--in my ditches.) Irrigation has been a struggle this year. Even with the water on for 36 hours there are some paddocks that have died back because I can't get water to them. Part of the problem is probably the old culvert--too deep and too small. It is half filled with mud that I can't get out. I taught a weaving class today but after that we went out to tackle the problem. Dan dug the culvert out with the tractor.

For tomorrow's irrigation the water will be running through the ditch. Eventually we need to replace the culvert with a bigger one.

After setting up the tarps to keep the water in the ditches I checked the paddock where I experimented with burning medusahead. This is the plot that my son burned early in the season. He didn't think it was effective but the medusahead is still gone.

The area of trefoil is where I burned the medusahead that was growing over it. This is some of the area that got water but that medusahead is still thick. I hope the pasture plants will choke it out.

This is some of the area that I haven't been able to irrigate. Not much forage there and look at the medusahead cover.

Here is the trefoil that would be a wonderful replacement for the medusahead. Hopefully irrigation will go a little better tomorrow and we'll get water on those dry areas.

Pasture management revisited

Regular blog readers may know that in the late summer and fall I start complaining about the unpalatable late summer grasses. I'm sorry, but I'm going to complain now even though it is only spring. I only graze about 7 acres so all of it seems precious. We dealt with some of the issues of the thick dallisgrass a couple of weeks ago by burning it. I hope something starts growing where all that heavy thatch was. Today's issue is the condition of the east paddock. Medusahead is a nasty, unpalatable grass that goes to seed in the summer, covering all the soil with thick dry thatch. The medusahead is starting to grow now and the only other thing growing with it is a perennial grass (Elymus--wild rye-- I think) that the sheep don't like either. The rest of the soil is covered with the dry residue from both of these. My goal in this paddock is to  graze it hard enough that they will at least trample and break up the dried up grasses from last year and hopefully eat some of the less palatable grass.

As I was uploading these photos I realized that they don't show what I've been talking about.

This is the view looking south. You can't tell, but it's the east side (left) of the east paddock that has the problem vegetation.  It took them only a day to clear off almost everything in the south part of this paddock (as opposed to 2 days in equal sized paddocks with better vegetation).

They are hungry and ready to move.

I took this photo as I opened the fence and stepped back so I wouldn't get trampled.

Arthritic Stephanie follows the running sheep.

Amaryllis brings up the rear. She will follow Stephanie anywhere.

This view is looking north, from the part of the paddock they just left. In this photo you can't really tell the difference in vegetation between the west (now on the left) and east sides of the paddock. It's much easier in person, but notice where the sheep are. There is no fence keeping them from the east side--it just doesn't have what they want to eat.

Compare this photo to the one where they are running into the new pasture. There is a blue cast to these plants--this is very sparse (although it may not look so in a photo from this angle) and it is so tall because the sheep avoided eating it the last time they were here.

Tomorrow I will start irrigating. I hope for some warm weather to follow so that the clover and trefoil will come in faster.

I'll race you to breakfast!

I'm pleased with the pasture this year, especially considering the number of sheep I have grazing. One 5-acre pasture is subdivided with electric fence (NZ spider fence) into 8 paddocks, each of which can be split in half using electric net fencing. There is one other 2-acre piece that I split in half. Here is the paddock the sheep went into yesterday.

If you go to the "prescribed burning" tag on the right you will see this same paddock (looking from the other direction). See all the dry grass? There was so much tall, rank dallis-grass that there was no green feed growing up through it. We burned it two years ago and with proper grazing I'm able to keep the dallis-grass in check and there is a lot of trefoil and other desirable plants. In the photo above it's those clumps that are the dallis-grass. The sheep eat it readily if it's kept in an early vegetative stage.

This is after I opened the net-fence at the end of this paddock and the sheep are going into the new one.

A few lambs who didn't get all the way around the fence and then started following the ewes back up the fence line on the wrong side. Now Rusty gets to help.

You can easily see the difference between the paddock they were just on and the new one. A paddock is not overgrazed by putting a lot of animals on it; it's overgrazed by time. Once a pasture is eaten low it needs to rest. If the animals continue to graze it as the new growth occurs, there will be negative impact on the root system and it will take much longer for the plants to recover. So the trick is to eat the paddock evenly and then move the sheep to a new paddock. By concentrating the sheep on a small area they eat all the plants, not just the ones they like best. This also helps with parasite control. right now with the lambs getting so big I'm moving the sheep every day or two. If I go through all the paddocks too quickly I may need to hold the sheep off and feed them in the barn for a little bit. I will probably try to coincide that with my next irrigation when I have to have sheep off the pasture anyway.

Another fence-line photo.

Entries for Solano County Fair were due this week so I needed to figure out who to enter. It was fun to separate out all my yearlings for a look. You get a different feel for the sheep when you get them out of the main group and I hadn't had a look at the yearlings as a group since they were lambs last year.

This is most of the 19 yearlings in the flock. There are some really nice sheep with with great fleece in this group. I narrowed the field down more and more until I chose my show sheep. (drum roll please....) And the winners are...

...Dazzle and Spring. They both have nice conformation, good size, and consistent fleeces. I have entered these two, the two yearling rams, and 4 lambs. Does anyone want to come help me show? It's June 22-24, a few days after Black Sheep Gathering.
