  1. 1. How do rainfall patterns change microbial induced carbon dynamics in soil?

    University essay from Lunds universitet/Teknisk mikrobiologi; Lunds universitet/Bioteknik

    Author : Maria João Silva; [2023]
    Keywords : drying and rewetting; bacterial growth; fungal growth; annual crops; perennial crops; soil depth; climate change; biotechnology; Biology and Life Sciences;
