The Global initiative of Crop Microbiome and Sustainable Agriculture aims to establish a global collaborative network – the CROP MICROBIOME survey – to collect soils from natural and cropland ecosystems worldwide. We aim to identify (1) a list of species of bacteria, fungi and micro-fauna; and (2) functional attributes characterizing the soil crop microbiome worldwide. We will focus on five functionally important and globally distributes crops: (1) rice, (2) wheat, (3) cotton, (4) corn and (5) potato.
