The contribution of compost

Composting is process that transforms organic material and enables the enhancement of nutritive elements at source for cultivation.

These elements improve the biological, physical and chemical properties of the soil and help crops resist drought, disease and toxic elements. This in turn improves performance and at the same times diminishes the need for mineral fertilizer.

Types of composting

There are two types of composting: aerobic (in the presence of oxygen) and anaerobic (without oxygen). These two mechanisms often exist together in the same compost.

Anaerobic composting

This kind of composting is defined by the development of anaerobic micro-organisms which degrade the organic material in intermediate compounds such as methane, organic acids, hydrogen sulphates and other products from fermentation. These compounds may give off odours and some of them may even be phytotoxic. This method, which takes longer than aerobic composting, is carried out at low temperatures, which limits the hygienization of the compost.

Nevertheless, anaerobic composting requires little work and greatly limits the loss of nutritive elements.

Aerobic composting

Contrary to anaerobic composting, this method requires a great amount of oxygen. This process especially produces carbon gas, ammonia, water and humus, and very few phytotoxic compounds.

Aerobic composting also emits heat, which accelerates the decomposition of the organic material and enables the hygienization of the compost by killing the other bacteria present in the manure. The disadvantage of this process is the greater loss of nutritive elements. It is, however, considered more efficient and more useful for agricultural production.

Depending on the substratum and conditions of preservation, one or the other kind of composting prevails. Manure is a naturally aired product, and so the activity of aerobic micro-organisms is therefore greater in composting.

Nolivade Microflora

The addition of Nolivade microflora to compost enables a faster activation of the composting process by providing supplementary bacteria. The Bacillus effectively secretes enzymes which promote the degradation of the organic material. This activity also lets off heat, the first stage of aerobic composting. The increased temperature then favours the growth of thermophilic micro-organisms for the second phase of composting. The Bacillus is then in conditions which are no longer favourable and so they form spores.

Spores are a highly resistant structure which enables bacteria to survive in this phase. They will germinate when they are in favourable conditions.
