Gravity’s always doing its best to take your fertility to the bottom of the hill. The following images explore a couple of ways to reverse this ever-present process, hopefully bringing a more positive slant to the old saying, “Pushing faecal matter uphill”.
This is a floodplain at Baramul stud, hydrated by the Natural Sequence Farming work completed by Peter Andrews. The pasture in the foreground is obviously lush and will provide some very decent feed, however, the tan coloured biomass in the background is equally interesting
This photo was taken standing on the back of a ute which Peter directed straight through this stand of Phragmites. The scale shows the considerable biomass produced as a result of the landscape hydration
Peter had said to me on many occasions that reeds make the best compost. So one day I gave it a go and what do you know, it did (and I’ve made my fair share). This was mainly cumbungi, but I’ve had similar results with Phragmites too.
A forage harvester, baling or in the gut of a cow are a few ways of moving the material up the landscape so that the compost is useful, as Peter Andrews mentions when talking about mulch farming in Back from the Brink.
Another plant that’s synonymous with water are willows, and the more fertile it is the better they grow.
Drop a willow near stock and see what happens. Sheep will strip every bit of bark off, as they have here on Peter and Kate Marshall’s property. Their sheep come to the sound of a chainsaw, as did the stock of a few people I have met, especially during the drought. That’s the time it’s valuable and research by the Kiwis has shown that with protein levels similar to lucerne, poplar and willow can maintain lambing rates during drought periods.
Because you’re close to water, the woody material which might otherwise get in the way can be used to fill in gullies and build more fascines and brush mattresses for erosion control.
With a feed value comparable to lucerne, poplars are another tree that grow on well-hydrated land, which stock will devour. The bark is especially high in trace minerals which are mined from deep down.
There are many varieties of poplars which can be used for different purposes, Populus trichocarpa being one which also provides useful timber.
Populus alba (silver poplar) is another, this stand provides good windbreak even when dormant, while the upright form minimises shading of pasture.
Pasture grows right up to the base of most poplars. The nutrients mined from deep down by the poplars are returned to the surface via leaf drop, enriching the soil beneath.
Browse blocks are utilised by the Kiwis which if grazed often enough don’t require felling with the chainsaw.
Using a number of tyres tech-screwed together, the Marshalls are able to establish poplars while the stock are still in the paddock. A large piece of cardboard eliminates grass competition during establishment. Tyres are removed when the tree is first pollarded.
Another use for a well hydrated floodplain is cricket bat willows. These ones are inoculated with white truffle, hence the oyster shells as a free, slow-release source of calcium.
Bamboo is another plant which does a fantastic job at stitching creek banks together, the foliage providing good fodder while the poles have a huge range of uses, one of which is a good cellular structure for biochar production.
And where do the stock head when they’ve got a gut full of all this? Up the hill of course, Nature’s anti-gravity nutrient transport service. Recognising this pattern, Martin Royds has realigned his fencing to facilitate this nutrient connection between watercourse (filter zone) and hilltop.
