Abstract:
Within 1 year (2009-2010) grass samples were taken from the respective fertilizer treatments (X=control; N=urea (50kg N ha-1 a-1); P=rock phosphate (10kg P ha-1 a-1); NP (combination of urea and rock phosphate 50kg N+10kg P ha-1 a-1) in 6 replicates, respectively) at 6 time points at the FERPAST. Grass yield within growth period as well as respective biomass properties were determined.

Title
:
cutting interval
Description
:
biomass yield was taken within a specific cutting interval, this information ist needed since the attribute "biomass_yield" gives the information about daily biomass growth within the specific growth_period

Measuring total amount of elements in plants with ICP-OES
Description
:
Total amount of elements (e.g. Ca, K, Mg, P, S) were determined by acid digestion (250mg, 50 ml HNO3, 180°C) and subsequent measurements by an inductively coupled with a plasma optical emission spectrometer (ICP-OES, CIROS, Spectro).
