The organic matter cycle: the basis of soil life

The good balance of the organic matter cycle is essential for the soil to remain an efficient support for the development of plants and the optimization of productions. In this cycle, the microbial biomass (bacteria, fungi...) plays a major role of transformer.

Under the action of the microbial biomass, the constituent elements of the organic matter deposited in the soil (lignin and cellulose / starch and proteins) begin two types of transformation:

The humification cycle: the lignin/cellulose enters a process that feeds the "stable humus" compartment of the soil, which will be mineralized in a second step and will provide nutrients to plants.
The mineralization cycle: the transformation of proteins and starch rapidly releases nutrients (mineral elements) that recharge the soil reserves and feed the plants.
The diagram below illustrates the different phases of this cycle.

Beware of organic matter deficits

The consequences of a deficit in organic matter are not immediately visible. However, they are multiple and detrimental to the optimal functioning of the soil from a physical (structure), chemical (reserves) and biological (microbial biomass) standpoint.


Choosing the right solution 

Vegetable matter is traditionally used as the basis for organic fertilization. They have a strong humigenous power (humus provider), which improves the soil structure, aerates it and improves its capacity to retain water.

The effectiveness of this organic plant contribution is reinforced by the incorporation of animal matter, which provides nutrients that are gradually released.

Depending on the case, the addition of selected mineral materials can target a particular impact on the soil and plants.

At Violleau, we formulate our products based on these different materials (animal, vegetable and mineral) to achieve maximum efficiency.

Whatever your objectives, we have a solution:  

To restore the soil's organic matter level (humification), choose a mass amendment (with plant matter) in the form of compost as a base fertilization.
To participate in the biological life of the soil (biomass) and bring nutrients (mineralization): bring organic and organo-mineral fertilizers in the form of plugs.
Our plugs can be placed in the fall as "bottom dressing" to recharge the soil, or in the spring as "cover" to ensure plant growth.
