Leila,
I am aware of Allan Savory’s work, and so are more and more South African farmers. Many are having a lot of success by applying the principle of managing grasslands by allowing very intense but short duration grazing with long recovery periods. But these ideas are more relevant to the extensive savanna and natural grassland ranches well North of here. But its great to see how ideas that were considered radical, like so much of permaculture, is slowly being accepted into mainstream farming.
I’m in the South-Western corner of Africa that gets winter rain. The remaining natural vegetation in this area is too valuable from a nature conservation point of view to be used for grazing, and besides the soils are too nutrient poor for sheep and cattle to survive on the stuff that grows around here. The more fertile lands have all been plowed and are quite intensely farmed, mostly wheat and wine.
We’re planning to turn a patch of ex-wheatlands into a permanent pasture for sheep and maybe pastured poultry, a classic Permaculture zone three strategy. Many farmers here simply plow annually and plant a monocrop of something like oats or barley for grazing and fertilise heavily. For planning what to grow and how to manage this pasture I have found that the most useful information comes from Australia. The area around Perth I think is very similar to here. I don’t think we could do this without the Internet.
In wet temperate zones, like where you are in NZ, pastures are mostly White Clover and Ryegrass and are quite easy to establish. But in areas with lower rainfall and seasonal droughts and weak soils it gets much more complicated. Pasture management and especially the selection of suitable blends of plant species becomes quite an advanced science. I am struck by how much of what get published by Australian agri academics sounds like Permaculture. Much of what they are doing is simply looking for suitable guilds, though they don’t use that word.
Just a couple of weeks ago we planted 20kg of seeds of four different types of pasture legumes. The seeds all come from Australia, but the species originate from all over the world. And instead of using a $64000 no-till planter, we made seedballs!
