We are developing a holistic DA model for a 7.53-ha nut alley cropping system at [Hof Lebensberg] (https://hoflebensberg.de/) (plot 1 of the German living lab under [ReForest project] (https://agroreforest.eu/). It contains a vartiety of nut trees: X rows of 420 Hazelnut (Corylus avellana) trees, X rows of 208 Walnuts (Juglans spp.) trees, X rows of 183 Chestnut (Castanea sativa/Aesculus hippocastanum) trees, X rows of 68 Pecan (Carya illinoinensis) trees, X rows of 89 Cashewnuts (Anacardium occidentale) trees, X rows of 73 Almonds (Prunus dulcis) trees, and X rows of 23 Hickory (Carya spp.) planted syntropically with shrubs. Between the tree rows, wheat, dinkel and einkorn are currently grown.
The farmers plan changing the system from silvoarable to silvopastoral once the shade of the trees start affecting the arable crop yield. A scenario of changing the system based on Gompertz curve for tree growth is being thought of. This will model provide recommendation to farmer about their planned system change.
Since the farmers have not registered the land as AF, the subsidy or financial support parameter will account for the type registered by the farmer.
The farm experienced wildfire in 2023. Therefore, based on the continuous dry days during peak summer from climate change data can be added to the model (??)
