Recovery of depleted soils with low agricultural production


The collaboration agreement signed by the Agricultural Technological Institute of Castilla y León and CARTIF, is focused on the valorization and application of technology to agricultural waste to increase the competitiveness of the agrifood sector in Castilla y León.

The main objective is recover exhausted soils with low agricultural production through the application of artificial soils made from mixtures of waste, by-products and products.
Proper combination of these wastes results in the “technosoil”. This new substrate with similar characteristics to fertile soil, reduces the environmental impacts (wastes valorization) and recovers/improves low-productive soils without excessive cost.


  • Development of different substrates to improve agricultural activity.
  • Select different wastes as raw materials and evaluate their role within the technosoil.
  • Determine the influence of different substrates on the soil, plants and seeds of different species, evaluating the technical-agronomic viability of the technosoils.
  • Demonstrate the benefits of implanting technosoils in degraded or depleted areas.


  • Selection, supply and management of the raw materials base of the substrates.
  • Formulation of the different substrates taking into account the composition of the raw materials.
  • Development and application of substrates in experimental plots.
  • Evolutive analysis of substrates in nursery-laboratory and in field.

Expected results

  • Obtain a database of the raw materials that may compose the substrates.
  • Elaborate a protocol for the management and treatment of raw materials for the development of technological substrates.
  • Develop several substrates and evaluate differences properties according to their composition.
  • Determine the influence of substrates on plants and seeds of different species and in different environments.

Natural resources projects:



Agricultural side streams-olives, wine, chicory and onions- are rich in bioactive compounds (BAC) and have antioxidant, antimicrobial, anti-inflammatory and anticancer properties. Their full potential has yet to be realised, due to a lack of technologies that preserve the complexity and functionality of these BAC.
