Planting a perennial pasture

We have been talking about perennial pasture for months now. Actually I wrote about it in July 2013, so its been nearly two years in the planning and discussing phase. This weekend we bought pasture seed, ploughed up about 10 acres and planted the first section of our 60 acres of cultivation land with a perennial pasture mix. What were we waiting for?  Rain mostly, and also just deciding what to plant and how to plant it....

eight acres: planting a perennial pasture
ploughing the paddock one last time

Here’s what I wrote before about why we wanted to try to establish a perennial pasture instead of growing forage for our cattle:
When we looked at how much we had spent on diesel, seed, and fertiliser just to plant these forage crops, which never made it to hay bales, we started to question whether it was really worth doing. Forage crops do have more energy and protein compared to perennial grasses, but they cost more to grow and are unpredictable in dry-land farming.

From a permaculture perspective, all this driving around in the tractor, ploughing and planting, when we could be just maintaining a perennial pasture, is not really optimising our yield. On a monetary basis, maybe when diesel and fertiliser were cheaper this was worth doing, but from what we have seen so far, and given that costs are only going to increase, we would be better to maintain a perennial pasture. And on a time and energy basis the arrangement is far from optimal. A perennial pasture that is established and just needs to be maintained with both careful management of cattle and the occasional dose of fertility enhancers would be more optimal in terms of energy, time and money. While we do occasionally need some hay if we have a really bad season, it would also be better for us to let the cattle do the harvesting, by strip grazing the paddock, instead of driving around making and stacking bales. And we can make hay from perennial pasture instead of planting forage.

As I explained in that post, our pasture currently consists mainly of African Love Grass.  Our cattle do eat it when its green, and to be honest, it is the first grass to grow after winter and is has sustained our cattle thus far. Unfortunately its the best grass we have, compared to blue couch and some other very feeble natives, but there are plenty of better species that we can plant. The three desirable traits in a pasture grass are:
  • Perennial - live for more than 2 years
  • Palatable - high proportion of leaf and actively selected by stock
  • Productive - produce large quantity of useful forage.
The main options in our climate and soil are:

Rhodes grass (Chloris gayana) 

Blue grass (Bothriochloa insculpta)

Digit grass (Digitaria eriantha spp. Eriantha)

Green Panic Panicum maximum var. trichoglume - (more useful in shaded areas)

eight acres: planting a perennial pasture


All of these are grasses produce tall, thick blades of delicious grass. The first two are spreading, while the others are tufted. We decided to plant a blend of the first three, with a legume (wynn cassia, which seems to grow well at our property)

I would have liked to plant and even wider variety, but we were limited by the cost of seed and the logistics of setting up the cultivator drill to plant the seed. We had some robust discussions about whether or not to plough. In the end we decided that one paddock really did need to be ploughed as it hadn’t been cultivated since we moved the house through that paddock, and it was starting to sprout some rather large wattle trees and had some bare patches with hard packed soil. Another area is starting to have some good grass established without our intervention, and so we probably won’t plough that area. 

eight acres: planting a perennial pasture
 

We used the “off-set” disc plough, which effectively turns the top of the soil, so the weeds growing in the paddock turned in as “green manure” and we didn’t worry about it being perfectly smooth or weed-free. We took some of the “boots” off the cultivator so that the seed would spray out more randomly, and the tynes were just touching the ground, so most of the seed sat on top or just below the soil. We mixed up a ratio of one bag Rhodes grass (the cheapest) and about half a bag each of Digit and Blue grass respectively, with a bit of Wynn Cassia mixed in. I would have like to get seed without a coating (I don’t even know what’s in the coating, but judging by the bright colours, I assume its not good, usually its has a fungicide), but it is very difficult to plant uncoated grass-seed as it tends to be very fluffy.

The afternoon after we planted we got some decent rain over the property, so we are hoping to continue to get showers through February and start to get this pasture established! We will be ploughing and planting the entire cultivation area (60 acres) gradually (and as usual, “we” means Pete drives the tractor and I cheer from the sidelines and open the occasional seed bag). After a very hot weekend, we were both very pleased to say, “if this works, that’s the last time we have to plough that ground”.

Not only is ploughing boring, hot, dusty, diesel-consuming work, it doesn’t help our soil. It destroys soil structure, and harms the microbial and macro-bial life in the soil (i.e. earthworms, if we have any). If we put our effort into building soil instead of ruining it, we should eventually see a more productive property and higher carrying capacity. We struggled to keep 20 cows and calves on 258 acres, so we certainly have room to improve!


Have you planted (or do you maintain) a successful perennial pasture?  What do you look for in you pasture?

  1. How exciting. I hope you see improved economics in the next few years. Another benefit of pasturing in this way is the ability of the stock to selectively forage and instinctively eat. Nan Bray in the Midlands here has taken a different approach to sheep grazing from anyone else here. She has seen how the stock will seek out certain plants for natural worming and other intermittent illness. She has some great stats to back up her practices now. Her stock are raised with far less chemical intervention. I think her story is available on Landline if you haven't seen it. Fingers crossed for some good rains for you.

  2. good luck!
    i've been hearing a lot about bio-dynamics from one of our volunteers at our markets, he never ploughs & uses his cow manure to do liquid fertilizing, one of them anyway, i love listening to him, it all sounds like it's getting back to nature, how grasses are meant to be grown, i saw a youtube of a woman who is going to be taking a farm over from her uncle & father too, she was talking about letting the natural grasses grow back. it's all very intriguing, please keep us updated with your progress.
    thanx for sharing

  3. One big step forward and many more to follow. So glad to be on this journey with you.

  4. Ha ha yes we have some 'robust discussions' about farm work around here too and I too am often giving my verbal support (putting my 2 cents in) from the sidelines. Do it once and do it well and I am sure you will be glad of it.

  5. Good grief, but I had a heck of a time getting to your blog. Used to be I could click on the name of a commenter, go to their profile, and select their blog. With G+, it goes to G+ which may or may not have an obvious link to the blog I'm looking for! LOL, anyway, want a great post. As you know, this is something we've been pondering as well. I so agree with this philosophy, but can't get around the fact that even perennial pastures (as you point out) have a relatively short lifespan. Still, this is better than doing it every year!

What to do with eight acres

Behind the scenes of my blog I can see the search terms that led people to find my blog.  It can be quite interesting to look through them occasionally and see what people are looking for.  Most of them involve chicken tractors, but another question that comes up regularly is “what can you do with eight acres?” or “how much land is eight acres?”.  Today I will try to answer this question.

Of course it is a very broad question, there are lots and lots of things you can do with eight acres, but I’m going to assume that you want to live there, feed your family and maybe make a little extra money.  I make that assumption because that’s what I know about, if you want to do something else with your eight acres, you will need to look somewhere else.

If you haven’t chosen your land yet, here a few things to look for.  Focus on the things you can’t change and try to choose the best property you can find in your price range.  Look for clean water in dams, bores or wells, either on the property …

Making tallow soap

For some reason I've always thought that making soap seemed too hard.  For a start the number of ingredients required was confusing and all the safety warnings about using the alkali put me off.  The worst part for me was that most of the ingredients had to be purchased, and some even imported (palm oil and coconut oil), which never seemed very self-sufficient.  I can definitely see the benefits of using homemade soap instead of mass produced soap (that often contains synthetic fragrance, colour, preservatives, and has had the glycerine removed), but it seemed to me that if I was going to buy all the ingredients I may as well just buy the soap and save myself all the hassle.  For the past several years I have bought homemade soap from various market stalls and websites, and that has suited me just fine.
Then we had the steer butchered at home and I saw just how much excess fat we had to dispose, it was nearly a wheel-barrow full, and that made me think about how we could use that…

Growing and eating chokos (chayotes)

Cooking chokos (not be confused with another post about cooking chooks) has been the subject of a few questions on my blog lately, so here's some more information for you.
Chokos - also known as Chayote, christophene or christophine, cho-cho, mirliton or merleton, chuchu, Cidra, Guatila, Centinarja, Pipinola, pear squash, vegetable pear, chouchoute, güisquil, Labu Siam, Ishkus or Chowchow, Pataste, Tayota, Sayote - is a vine belonging to the Cucurbitaceae family, along with pumpkins, squash and melons, with the botanical name Sechium edule.


The choko contains a large seed, like a mango, but if you pick them small enough it is soft enough to eat.  If you leave the choko for long enough it will sprout from one end and start to grow a vine.  To grow the choko, just plant the sprouted choko and give the vine a structure to climb over.  In summer, the vine will produce tiny flowers that will eventually swell into choko fruit.  The vine doesn't like hot dry weather.  And it doesn&#…
