​The Vanhoof test is something like a system analysis of the symbiosis between plant and soil biology. Some aspects we can just see with the naked eye, others are made visible by the microbial test or a chemical analysis. In our approach both points of view are important to make the picture complete.

​

• Own measurements in (mobile) lab

  • physical condition of the soil (pH, redox potential, EC)

  • how many nutrients are available immediately without soil biology (mineral salts)

  • witch part of them could quickly leach out

  • how does the decay of organic material take place: through rotting or aerobic decay, with a mineralisation or fixation?

  • how reacts symbiotic microbes in the rhizosphere to root exudates? How many nutrients do they deliver to the plant?

  • respiration of soil biology, which fertilizes the crop with CO2

  • is there a chance/risk of denitrification / nitrification, nitrogen fixation, humus build-up / oxidation / reduction...

• Own observations on the plot

  • the soil profile to a depth of at least 40 cm

  • the soil as a house for biology: structure, moisture status, soil compaction

  • how does the crop feel on the plot? rooting depth, crop condition

• Additional data from other analyses

  • chemical analysis shows which and how many minerals are present

  • plant juice measurements/feed analyses show what has really been taken up by the crop
