<p>A nutritive growth material suited for compaction into plantation bales in admixture with an organic binder comprises the following components: a) Lumpy sphagnum for retaining water, b) Hygroscopic long-fibered sphagnum, c) Fine sphagnum for mechanically stabilizing the other components, d) A nitrogen rich and only slightly decomposed material such as grass, straw or leguminous plants, e) A slowly decomposing nutritive material such as sea wrack which is rich in nutritive minerals such as iodine and boron, and g) Clay. The bales are mountable in suitable support structures to form very stable plantation walls or sound walls, which will remain sufficiently self-nutritive over a long row of years.</p> |
