The Holzer Permaculture is a branch of permaculture developed independently from the mainstream permaculture in Austria by Sepp Holzer. It is particularly noteworthy because it grew out of practical application and was relatively detached from the scientific community.
Sepp Holzer started reorganising his father's property according to ecological patterns in the early 1960s after he took over the farm. As an adolescent he conducted layman experiments with plants native to the area and learned from his own observations.
His expanded farm now spans over 45 hectares of forest gardens, including 70 ponds, and is said to be the most consistent example of permaculture worldwide. In the past he has experimented with many different animals. As a result of these experiments, there is a huge role for animals in the Holzer Permaculture.
He has created some of the world's best examples of using ponds as reflectors to increase solar gain for passive solar heating of structures, and of using the microclimate created by rock outcrops to effectively change the hardiness zone for nearby plants. He has also done original work in the use of Hügelkultur and natural branch development instead of pruning (see Fruit tree pruning) to allow fruit trees to survive high altitudes and harsh winters.
Comparison to regular permaculture
It is difficult to make out differences between the methods and practices of Sepp Holzer in contrast to the more scientific and theoretical permacultural mainstream. Nevertheless, here are some major points to consider:
- His designs are mostly aimed at raising temperatures and creating micro-climates with rocks, ponds and living wind barriers, in an area with 4 °C on the average and -20 °C in the winter. The ponds he makes do not contain any pond liner. Instead, he makes the ponds watertight by sifting the fine from the coarse soil in the earth pile dug up with the excavator. The excavator is then used to pile only the coarse soil up into walls which are then tampered down using the excavator's bucket. The bottom of the pond, he makes watertight by vibrating the excavator's bucket when the pond has been filled with 30–40 cm of water.
- Another aspect was the necessity of creating terraces on his farm's hillsides leading him to the use of heavy machinery (like excavators). Many of the terraces he construct are also given a humus storage ditch (placed in between the terraces).
- Famous is his Hügelkultur technique, which is basically the use of raised beds in which he uses bulky material such as tree trunks. On his farm, he made a pick-your-own area where visitors can pick their own produce from the raised beds and then pay for it at a counter upon leaving the area.
- He uses animal labor alongside human labor, working his farm with only two people. He optimizes the natural patterns of animal behavior to reduce human or machine-driven labor. As an example: he uses swine to "plow" new beds for sowing. This is a very effective way of digging, as the only thing he has to do is to throw some corn and fruit on the spot he wants dug up. A couple of days later, he can bring the pigs back to their enclosure and plant new plants in the bed. Holzer is able to successfully grow his plants without using any fertilizer. The animals he uses are all heirloom races, which are hardy and require (almost) no maintenance. Examples of the races of swine he uses are Mangalitza, Swabian Hall swine, Duroc, Turopolje, ... He also keeps quail, capercaillie, hazel grouse, wisent, scottish highland cattle, hungarian steppe cattle, Dahomey miniature cattle, American bison, yak, water buffalo. He has the animals live outside, in paddocks/shelters and has them share space with orchards and forests. Many of the fruit trees in the orchards (especially those on very sloped terrain) are used exclusively to feed the animals. They collect it as it falls to the ground (those trees are hence not being picked/ nor is produce of it sold)
- He also does not prune fruit trees much nor does he cut the lower branches on fruit trees (as this can hurt the tree -due to the lignification not being able to complete before frost and the fact that the unpruned fruit trees survives snow loads that will break pruned trees.-. He also says that leaving the branches on protects the tree against browsing by animals. He does however makes a point of using deep-rooted pioneer plants such as lupins, sweet clover, lucerne and broom. These crops are said to aerate the soil and make sure no water is left standing near the tree. No use is made of wire meshes as protection against voles, since he states they are not efficient in preventing damage from voles using this technique anyway. He makes no use of contemporary fruit tree cultivars, but only uses (very strong/hardy) old, local (heirloom) cultivars. In addition to (old cultivars of) regular fruit trees, he also plants much fruit tree species that are specific to use in phytotherapy or which can only function as animal feed (i.e. crab apple, wild pear, wild cherry, blackthorn, rowan, wild service, service tree, cornelian cherry, snowy mespilus, ...). Similar to mainstream permaculture, he makes no use of chemical fertiliser or pesticides, at all. It should be noted that due to the altitude he's at, his trees bear fruit later, meaning he can sell it after most (sealevel) farmers sold their produce. Due to this (and the fact that he produces heirloom fruit varieties, and not regular varieties), he is often able to get a better price for it. In some cases, customers (like distilleries) are even willing to pick the fruit themselves, eliminating the labour expense for him.
- He grows many old cereals on his farm, such as einkorn, emmer, black emmer, spelt, fichtelgebirgshafer, wild rye, black oats, naked oats, barley, Siberian grain (secale cereale, russian cultivar), tauernroggen, ...
- He also makes much use of green manure crops (like stinging nettle, phacelia, yellow, white and narrow-leaved lupin, garden pea, grass pea, fodder & Kidney vetch, yellow, subterranean, Crimson, Persian, Egyptian, red & white sweet clover, Birdsfoot trefoil, lucerne, black medick, Sainfoin, Serradella, fiddleneck, sunflowers, Jerusalem artichoke, Gold-of-pleasure, ...)and grows these crops extensively on his farm. He leaves them standing in autumn, rather than digging them in. He instead relies on natural decay of the plants. He often relies on the natural spreading of the seeds of the crops for their re-sowing.
- Another aspect is the abandonment of other horticultural principles such as intercropping plants with very high and very low pH requirements (for example, Rhododendron with roses). Instead, Holzer mixes thirty or more different types of seeds in a bucket and tosses the mix richly onto a larger area.
Situated in Ramingstein on the slopes of Mount Schwarzenberg his farm (Krameterhof) lies at varying elevations ranging from 1100 to 1500 metres above sea level.
The exceptionally harsh climatic conditions in the area are generally considered inappropriate for farming. Nevertheless, he has managed to cultivate a variety of crops and even exotic plants like Kiwis and Sweet Chestnut.
The Krameterhof is less an operational enterprise, in terms of crop-yield (although it does provide numerous sorts of produce for the community), and more a fully functional showcase or research station for permaculture.
Endangered livestock species and rare alpine- and cultural plant species are integrated into the farm.
