(1) Just a word of caution: Be certain that you are really growing "Eucalyptus" trees = Botanical Genus EUCALYPTUS as in Eucalyptus globulus variety globulus = one of many varieties of "blue gum" distilled to produce medicinal eucalyptus oil. I do not know of any Eucalyptus species that grow where it snows. Eucalyptus trees are tropical or sub-tropical. They do not tolerate hard freezes. How you can grow Eucalyptus in England is a wonder of forestry.

In hardwoods, they drop their leaves every year, while with softwood they self prune their branches. As these fall to their base anything under 2 inches in diameter, within two feet of the ground, within two years will decay, at least in New England where I live anyway. This ultimately ROBS the soil of nitrogen as it breaks down that woody mass.

After a bit of time however, about 7 years, that process changes and the nitrogen is released.

Cover crops are almost impossible to compare to hugel construction because they really are apple and oranges. I use cover crops on my farm, but the amount of nitrogen fixing they do is very slight compared to hugel construction simply because their lifespan is so short. I use them more for erosion control than fertilizer. It definitely is not enough to grow a high yielding crop on. With hugels (using wood) you do not have that issue, they are self-fertilized by definition since they use so much nitrogen-laden mass.

The challenge of permaculture is often how to make the best of a less than ideal situation. Yes, hillsides beyond a certain degree of slope are best left in forest, but "what if"?
