  1. Soil: Add slurry to the soil

    A meta-analysis from 2013 of studies in Mediterranean climates found similar percentages of organic carbon in soils with or without added slurry. Organic matter: There was no difference in organic carbon between soils with or without added slurry (2% higher in soils with slurry). Methods: Slurry included liquid pig and cattle manure, both raw and digested. The Web of Knowledge database was searched, using the keywords, “Mediterranean”, “soil”, and “conventional”, and 3 data sets from 3 studies of slurry amendment were found and meta-analysed. The most recent studies included in this meta-analysis were published in 2011.

     

  2. Soil: Plant or maintain ground cover in orchards or vineyards

    A meta-analysis from 2013 of studies from multiple Mediterranean countries found a higher percentage of organic matter in soils with cover crops, compared to bare soils. Organic matter: A higher percentage of organic carbon was found in soils with cover crops, compared to bare soils (10% higher). The Web of Knowledge database was searched, using the keywords, “Mediterranean”, “soil”, and “conventional”, and 13 data sets from 10 studies of cover cropping were found and meta-analysed. The most recent studies included in this meta-analysis were published in 2011. It was not clear how many of these studies were from arable fields, orchards, or vineyards.

     

  3. Soil: Use organic fertilizer instead of inorganic

    A meta-analysis from 2013 of studies in Mediterranean climates found a higher percentage of organic carbon in soils with added organic matter, compared to conventionally fertilized soils. Soil organic matter: A higher percentage of soil organic carbon was found with than without added organic matter (24% higher). Methods: The Web of Knowledge database was searched, using the keywords, “Mediterranean”, “soil”, and “conventional”, and 37 data sets from 26 studies of organic amendment were found and meta–analysed. The most recent studies included in this meta–analysis were published in 2011.

     

  4. Soil: Grow cover crops in arable fields

    A meta-analysis from 2013 of studies in multiple countries with Mediterranean-type climates found a higher percentage of organic matter in soils with cover crops, compared to bare soils. Organic matter: A higher percentage of organic carbon was found in soils with cover crops, compared to bare soils (10% higher). Methods: The Web of Knowledge database was searched, using the keywords, “Mediterranean”, “soil”, and “conventional”, and 13 data sets from 10 studies of cover cropping were found and meta-analysed. The most recent studies included in this meta-analysis were published in 2011. It was not clear how many of these studies were from arable fields, orchards, or vineyards.

     

  5. Soil: Use no tillage in arable fields

    A meta-analysis in 2013 of studies from multiple Mediterranean countries found a higher percentage of organic matter in soils with no tillage, compared to conventional tillage. Organic matter: A higher percentage of organic carbon was found in soils with no tillage, compared to conventional tillage (in herbaceous crops: 18% higher). Methods: No tillage included herbicide use. The Web of Knowledge database was searched, using the keywords, “Mediterranean”, “soil”, and “conventional”, and 33 data sets from 21 studies of no tillage were found and meta-analysed. The most recent studies included in this meta-analysis were published in 2011.

     

  6. Soil: Use reduced tillage in arable fields

    A replicated meta-analysis from 2013 of multiple Mediterranean countries found a higher percentage of organic matter in soils with reduced tillage, compared to conventional tillage. Organic matter: A higher percentage of organic carbon was found in soils with reduced tillage, compared to conventional tillage (15% higher). Methods: The Web of Knowledge database was searched, using the keywords, “Mediterranean”, “soil”, and “conventional”, and 17 data sets from 12 studies of reduced tillage were found and meta-analysed. The most recent studies included in this meta-analysis were published in 2011.

What Works in Conservation

What Works in Conservation assesses the research looking at whether interventions are beneficial or not. It is based on summarised evidence in synopses, on topics such as amphibians, bats, biodiversity in European farmland, and control of freshwater invasive species. More are available and in progress.
