Why have my compost analyzed?

The analysis of the compost allows us to know its agronomic value. It informs about the fertilization to bring to make a success of your vegetable or pleasure garden.

Description of the analyzes carried out by the laboratory

Dry matter (DM) : Corresponds to the percentage of product when the water is extracted

Organic matter : Comes from the degradation of microorganisms, plants, animals

Total nitrogen : Total nitrogen includes mineral (ammonia, nitrates, urea nitrogen) and organic forms. The majority of organic nitrogen must mineralize in the soil to be transformed into ammoniacal nitrogen.

Ammonia nitrogen : This form of nitrogen is readily available, it represents only a small proportion of total nitrogen unlike organic nitrogen.

C / N report : Provides information on the state of degradation of organic matter

Phosphorus : Information on available phosphorus is expressed as P2O5

Potassium : Informs about the available potassium is expressed in K2O (potash)

Calcium : Informs about the available calcium is expressed in CaO (lime)

Magnesium : Informs about the magnesium available is expressed in MgO (magnesia)
