As you all, know, we still aren’t living on our farm. We’re getting close, and hope to move in by the end of September. But in the meantime, we have been sticking to research rather than hands on farming.
Having said that, it’s still been a frustrating experience. I was hoping for some guidance in how to improve our land. A template to follow, if you will. And each book we’ve read has been a template to follow of sorts, but none of them fit our situation.
Linda Woodrow is one of my favourite writers, but she is much better on a home scale than on 20 acres. Her advice for improving damaged land involves running chooks and importing heaps of organic material. Other farmers I know who have tried her techniques have struggled to implement them commercially.
Bill Mollison, P A Yeomans and Peter Andrews all concentrate on large scale properties. What they have learned and written is brilliant. As well as incredibly useful: most of Australia has huge problems with low rainfall and dry soils. They all recommend holding water on your property for as long as possible. Unfortunately, I don’t think they meant in large anaerobic puddles, or mud pugs. Our average annual rainfall is around 800mm. Obviously we still need water on our property, but it’s not as simple an equation when the water has the potential to flood.
I’ve read Sepp Holzer, but most of what he covers in his book “Permaculture” involves steep slopes, and terracing as that is where he grows. Our land is flat. He does mention allowing wet areas to be wet. He recommends turning them into ponds or wetlands, but most of our property is wet, so his advice isn’t feasible for us.
I’m now partway through Masanobu Fukuoka’s The One Straw Revolution. It’s brilliant reading, but like all the others, it’s not specifically useful to us.
Our water table is quite high. According to Visualising Victoria’s Groundwater it’s roughly 5m below the surface. Our land is almost entirely flat. The soil is a heavy clay, and the worst parts of it crack dreadfully in summer. In winter it’s waterlogged and soggy.
For the last few years it’s been slashed regularly with a tractor. Our neighbour’s sheep have been overstocked and overgrazing our paddocks. The soggy paddock didn’t seem to bother either the sheep or the tractor.
We suspect severe compaction as a result.
All of this amounts to a significant problem if we want to run stock. As well as problems if we want to plant fruit trees and vines: their roots don’t like water logging. Regular annual crops also dislike water logging, and any drainage put in to deal with it, will compound the drying out over summer.
I don’t expect any of the permaculture bibles to cater to us perfectly. The idea of permaculture is that it’s based around principals, not instructions. After all, no two pieces of land are the same. Permaculture is a method of observation. You watch what occurs or doesn’t occur in nature, and replicate or avoid as you can. We can follow those principles. We will do that. We’ll experiment.
But I can’t help wishing a few more of the templates and examples given were for flat land, or compacted land, or waterlogged land. By 1992, Victoria had 1.8 million hectares of land affected by water logging. And it’s only getting worse. Water logging can lead directly to soil salinity. It’s a serious problem, throughout all of our dairy country. Ours is a severe case, with flooding and standing water sitting on the surface. As I drive to and from Moorooduc, I see a lot of our neighbours have similar situations.
Given that the problem is so prolific, I expected to find a great deal of information on it online. So far all the advise I’ve found has been on how to determine whether you need surface or subsurface drainage. Obviously all things have a place in holistic management, but I don’t think these should be the first or only port of call.
I haven’t been able to find a template, or even techniques for how to proceed. There don’t even seem to be failed experiments recorded. Perhaps ours will be the first!
We need to determine how much of our water logging is from surface water, and how much is subsurface, that is, a high water table. We’re hoping that it’s surface water struggling to drain away due to compaction and damaged soil, as that is much easier to fix. If the water table has risen high enough to be water logging the surface, longer term solutions will need to be found.
The digging on Thursday will be wet and dirty work, but hopefully it’ll help us develop a new template for people to follow.
