Nutrients in greenhouse soil 

Nutrients in greenhouse soil can be freely available or they can be bound to soil particles. The ratio between organic matter and clay particles determines how strongly the elements are bound to the soil particles.

Factors playing a role

The fertility of greenhouse soil is not determined purely by the minerals present and their availability. The following factors also play a role:

Organic matter

Acidity (pH)

Moisture retention capacity (pF)

Soil life

Greenhouse soil analysis

At Eurofins Agro we offer a complete package of greenhouse soil analysis for identifying the chemical, physical and biological properties of the soil. There are two options for analyzing greenhouse soil:

• Before cultivation (Greenhouse SoilStock)
• During cultivation (Greenhouse SoilCheck)

With the Greenhouse SoilStock you can make sure you take the right action to optimize your greenhouse soil fertility before the crop goes in. A greenhouse soil analysis will give you the information you need for this. During the crop cycle it is important to monitor the availability of nutrients. This can be done with the Greenhouse SoilCheck.
Eurofins Agro’s fertilization analysis gives information about the condition of greenhouse soil and absorption by the crop. We offer two types of greenhouse soil analyses:

The total picture of the fertility of your soil:

Chemical: N-total soil reserve, C/N, N supply capacity (NSC), S total soil reserve, C/S, S supply capacity (SSC), K soil reserve, Ca soil reserve, Mg soil reserve, Na soil reserve, P plant available, P soil reserve

Physical: pH, organic carbon, organic matter, organic matter balance, calcium carbonate, clay, silt, sand, CEC, Ca, Mg, K, Na, Al and H saturation %, structure pyramid, friability, capping, pF-curve.

Biological: Microbial biomass, microbial activity, fungal and bacterial ratio.

Method

Eurofins Agro analyses samples according to prescribed and established methods. The analysis report briefly describes the method. Here you can also see which method has been accredited by the Accreditation Council. We then put a Q after the method.

In the tab Downloads, in the document “Methoden Horticulture onderzoek” (in Dutch) you will find a detailed description of the methods. This document supplements the information on the analysis report.
