Both spin-ups recycle years of piControl climate data and use a constant CO2 concentration of Using a combination of plant physiological relations, generalized empirically established functions and plant trait parameters, it simulates processes such as photosynthesis, plant growth, maintenance and regeneration losses, fire disturbance, soil moisture, runoff, evapotranspiration, irrigation and vegetation structure. Nitrate moved to the lower soil layer with percolation NO 3 – perc , l is calculated as. Furthermore, nitrogen transformation in soils is simulated in a more sophisticated way incorporating the immobilization of nitrogen. Global Change Biology, doi:

The establishment of PFTs in natural vegetation is constrained by climatic suitability and the density of the existing vegetation, whereas their mortality depends on climatic stress i. Is cropland soil management included?

Outputs are generated as daily, monthly or annual spatially explicit time series for individual plants, carbon and water pools and fluxes, individual land-use types or the entire mosaic present in each grid cell.

Water demand is then recalculated using the reduced V max. Carbon dynamics are mostly unchanged from the predecessor version LPJmL3. Drivers and patterns of land biosphere carbon balance reversal. Windows installer available for download from http: First, for each soil layer the fluxes of carbon from the soil into the atmosphere are calculated and the respective fluxes of Nreflecting the actual C: For this approximation, we use the allocation shares of the previous year f rootf sapwood:.
To calculate the limitation opjml N availability, N stress is calculated after determining water stress on photosynthesis.
N ratios of roots and sapwood relative to the C: The system is solved for a 1a 2… a n so that the relative ratios R 1…R n – 1 are ensured. Search Site only in current section.
Impact of abundance weighting on the response of seed traits to climate and land use, J. Finally, the amount of nitrate that is removed with surface runoff NO 3 – surf and lateral flow NO 3 – latl is calculated as.
