With the aim of improving the fertility and productivity of the client’s vine crops, the best fertiliser was selected from a number of suppliers to achieve the desired physical, chemical and biological fertility properties, as well as to improve the yield and quality of the grapes. Taking into account the edaphological characteristics of the soils and their nutritional needs, a fertiliser was chosen with the capacity to solve possible soil deficiencies, while also providing great stability, both physical and chemical. On this basis, the application rate of the fertiliser/fertiliser required was also determined.
