ANALYSES
Why analysis is necessary?
Fertilization is the application of compounds containing one or more plant nutrition elements either to the soil or straight to the plant itself to reach the yield and quality aimed in agricultural production.
Relevant, balanced and timely fertilization is only possible by organising a fertilization program based on the soil, plant and irrigation water analyses. When the fertilizer is used more or less than it is necessary, herbal production is inefficient and poor.
As DOKTOLAB, we highly recommend you to have an analysis done in a licenced laboratory before plantation.
