Forage Quality — LTAR Aspirational Cropping System Experiment (ACSE)
Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use
Forage quality is an important measure of the value of a crop for livestock consumption. We measure a variety of quality indicators that are summarised in this table. Samples are collected when the biomass is removed from the field, For forages this might be a few days after the crop is cut.
This datatable is part of the LTAR agronomic production datasets dataset.
