Dataset paper "N2 use in perennial swards intercropped with young poplars, clone I-214 (Populus × euramericana (Dode) Guinier) in the Mediterranean area under rainfed conditions"

Description

These files contain the data produced within a 2-yr field experiment conducted in Pisa, Central Italy, to assess N dynamics in a young silvopastoral system (i.e., where two forage crops, sulla and ryegrass, were grown in intercropping with an alley row of poplar trees) compared to a pure pastoral system (i.e., where teh afore-mentioned forage crops were grown without trees). Specifically: - "15N_poplars_Ntransfer.csv" contains the data on N2-transfer from sulla to poplar trees - "Averaged cumulate values.csv" contains the data on aboveground biomass, N yield and N fixed of the forage crops, cumulated over the two years of experimentation; - "Poplars growth.csv" contains the data on plant height and trunk diameters ( at the foot and at 130 cm) collected on poplar plants at different dates (at plantation time and at the end of each experimental year); - "Root_N_Nfix.csv" contains the data on delta 15N, %N derived from fixation and N concentration in poplar tree roots sampled at the end of each experimental year; - "Seasonal Data_AGB_N_Nfix.csv" contains the data on aboveground biomass, N yield, delta 15N, %N derived from fixation and N concentration and N fixed of forage species observed at each sampling time (mowing date) within the two experimental years; - "Soil_N_only SIPAST.csv" contains the data of soil total Nitrogen and nitric Nitrogen observed only in the silvopastoral system at different positions on the field; -"Soil_N.csv" contains the data of soil total Nitrogen and nitric Nitrogen observed in the two cropping systems at different positions on the field.
