The nourishment of a plant is an extremely complicated process, which is influenced by the supply of nutrients in the soil, on the one hand, and by conditions such as humidity, aeration or season on the other.
A soil analysis indicates the soil's status at the time of sampling. The examination of nutrients allows to clearly identify nutrient-poor, sufficiently supplied or oversupplied soil and thus to determine appropriate measures.
In addition, through analysing further chemical, physical and biological parameters, further recommendations can be obtained for soil management. This overall assessment of nutrient availability and permanent soil characteristics results in an image of the functionality – and thus the 'health' – of soils. Soil analyses are therefore not only useful for farmers and horticulturers, but also for hobby gardeners.
