DE2643443A1 - Plant growth medium prodn. - by composting vegetable waste using mixt. of specified plants treated with argillaceous mineral or diatomaceous earth as accelerator - Google Patents

Abstract

Prodn. of plant growth medium comprises layered composting of 70-90 wt.% vegetable material, organic kitchen waste etc., the remainder being mineral components, e.g. clay, sand, lime etc. Each layer is treated with a composting accelerator consisting of a thinned mixt. of Achillea millefolium, Urtica dioica and opt. Matricaria chamomilla, Taraxacum officinale, Valeriana officinalis, oak bark and/or honey. This is spread in a wt. ratio of 1:103-105 with a powdered argillaceous mineral (I) and/or the same amt. of diatomaceous earth and with 1-3 kg/m2 of compost. (I) is pref. bentonite, attapulgite or montmorillonite.

Description

Method of making a

Plant substrate It is known to produce a plant substrate by layering it Composting 70 to 90% by weight of plant material, organic kitchen waste and the like, remainder mineral constituents, such as clay, sand, lime and treat each Layer with a composting accelerator containing a diluted mixture of herbs from Achillea FIillefolium (yarrow), Urtica dioica (nettle) and possibly Taraxacum officinale (dandelion), Vilariana officinalis (valerian), Cortex quercus to make robur (oak bark) and / or honey.

The layers should not exceed about 30 cm and the total height of the heap to be composted should not significantly exceed approx. The composting accelerator acts to accelerate the Rotting process, the in 6 to 12 weeks at least until a certain raw fermentation is complete. Though plant material can be produced in a relatively short time even without the composting accelerator compost, but there are certain undesirable processes, such as certain Putrefaction processes and a sticky end product cannot be ruled out and germs as well Weed seeds are retained, which is what happens with the method using the herb accelerator is not the case, as temperatures up to the beginning of the rotting process occur at 800C and thereby a selection of bacteria and killing undesirable Germs and seeds takes place. However, for the application of the well-known herbal It is important that the accelerator is in a very finely divided form to the composting Mixture is added. This is done by grinding the herbs very finely and suspending them the herbal powder in water with thorough stirring or

Shake and pour on or splash on the suspension achieved. A disadvantage of this relatively cumbersome production of the composting accelerator can be seen in the fact that the suspension is not indefinitely stable, but within must be used for a maximum of 3 weeks, otherwise it will rot, and that includes the herb mixture is not indefinitely durable.

It has been found that these disadvantages can be avoided if in the known method mentioned at the outset, the herb mixture is in a weight ratio from 1: 103 to 105 with a powdered clay mineral and / or with diatomaceous earth evenly rubs in and of the mixture 1 to 3 kg / m3 of compost as a composting accelerator begins.

It is sufficient if the unmilled herbs together with the carrier, Clay mineral or diatomaceous earth serving as diluents and durability enhancers be ground until an even, fine distribution and mixture of the ingredients is achieved.

The clay mineral or the diatomaceous earth have to be at the same time Composting mixture has an effect in terms of promoting humus formation and Buffering of the humic acids, which serves the desired bacterial growth. aside from that the mixture binds moisture and thus creates favorable conditions for rotting.

In particular, bentonite, attapulgite or montmorillonite are used as clay minerals in question, which also have an ion exchange effect, which apparently is beneficial acts on the mixture to be composted. These can also be sprinkled particularly well and are therefore easy to use.

The herbal mixture preferably consists of the dried flowers of the plants mentioned, with the exception of Urtica dioica, of which one is called the aboveground Plant parts used, and oak bark or honey. If you wish, others can additives known per se can also be used, in particular other known additives Herbal additives or organic fertilizers such as horn shavings and the like. Additions of artificial fertilizers should be avoided.
