# A comprehensive dataset gathering 37 cover crop field experiments across France (2004–2022): plant and soil-related agronomic variables on 33 crop species from five botanical families

## TL;DR

This paper presents a dataset of 37 cover crop experiments in France, tracking plant and soil variables for 33 species over 19 years.

## Contribution

The paper introduces a comprehensive, long-term dataset on cover crops in France, including diverse species and environmental conditions.

## Key findings

- The dataset includes 33 cover crop species from five botanical families, measured over 19 years.
- It provides agronomic data on plant and soil variables, along with climate and management details.
- The resource supports evaluating cover crop performance and sustainability.

## Abstract

Cover crops, sown between cash crops to provide ecosystem services, contribute to sustainability but present challenges related to the use of environmental resources out of the main cropping season. This dataset gathers the results of 37 field experiments related to cover crops, whether grown in sole crops or in mixtures, conducted in France over 19 years. It compiles quantitative data from field measurements and laboratory analyses on 33 species among five botanical families, along with information on technical management and climate conditions, providing a valuable resource for assessing cover crops performance.
