Biodiversity Foundation Project: Application of compost from municipal waste to agricultural soils and pastures

Description

One of the main causes of desertification, an indicator of climate change, is the removal of organic matter from soils. This is essential for good physical, chemical, and biological conditions, its fertility, its agricultural use, and the prevention of soil erosion, and is an important factor in adaptation. "Application of Compost from Municipal Waste to Agricultural Soils and Pastures" is an initiative of Friends of the Earth Spain, supported by the Biodiversity Foundation of the Ministry for Ecological Transition through its 2017 grant application program.

Description of activities

The project was based on two fundamental pillars. First, practical experiments were conducted with the application of compost from 18 sources to 22 soils with different characteristics, distributed regionally across the peninsula. Another pillar was laboratory analysis of the characteristics of the compost used, as well as of the soils before and after application.

Objectives

Developing new applications for compost from municipal waste has led to a study to demonstrate and improve practices in this regard. This study demonstrates that applying compost from municipal waste to Spanish soils contributes positively to climate change adaptation.

Results

Using the data extracted, the potential for implementing these practices to improve the resilience of Spanish soils to climate change, reduce greenhouse gas emissions, and the potential for using compost from municipal waste on arable soils has been calculated.
