How many biogeochemical cycles are there

WebThere are also three types of biogeochemical cycles interconnected: Gaseous: macro and micronutrients are rapidly recycled and circulate between the atmosphere and living things. The oxygen, carbon and nitrogen cycle stand out. Sedimentary: elements (eg phosphorus and sulfur) circulate between the earth's crust, hydrosphere, and organisms and ... WebApr 13, 2024 · We measured soil CO 2 fluxes during wet-dry cycles from 2015 to 2024 in four Panamanian forests that vary in rainfall and soil fertility. Measured soil CO 2 fluxes declined in the dry season and peaked in the early wet season ahead of peak soil moisture, resulting in lower soil moisture optima for respiration than previously modeled.
