Indicative Value of the Dominant Plant Species for a Rapid Evaluation of the Nutritional Value of Soils
A study was conducted on 14 grassland communities located in the south of the Iberian Peninsula and their edaphology, which is identified as specific plant associations. The edaphic study of each association allows a rapid evaluation of the nutrient content in the soil without the need for laborator...
