Compost vs biochar amendment: a two-year field study evaluating soil C build-up and N dynamics in an organically managed olive crop

摘要

Despite the high interest in biochar as soil amendment, the number of field studies is still limited, being experiments with perennial crops in arid lands particularly lacking. This study evaluated the application of compost and biochar in a drip-irrigated organic olive crop in a calcareous soil in South-East Spain.
