Table 3 Soil column set-up for the Lolium perenne and Medicago sativa intercropping experiment

From: Real-time monitoring of rhizosphere nitrate fluctuations under crops following defoliation

  1. Columns underwent the management practice as colour coded as follows; pink for planting with 80:20 L. perenne cv. Aber Magic and M. sativa cv. Daisy seedlings, at a seeding rate of 43.7 kg ha−1 to match the forage industry standard; blue for day 0 nitrate application with KNO3 treatments equivalent to 57 kg ha−1; purple for day 28 total aboveground vegetative defoliation with biomass measurement. All columns with crops growing were cut on day 56 for harvesting the biomass total, and in the case of ‘Monocrop 3′ this new growth mass was added to the day 28 biomass measurement
