On the 19th March 2018, soils samples were collected at each site from 0-10 cm and 10-30 cm depth from 15 randomised locations, within each experimental area. Soil was sent to CSBP and tested for pH (CaCl2), Organic Carbon, P, K, S, exchangeable cations, reactive Fe and Al, available Ammonium and Nitrate N and electrical conductivity.
Two PreDicta B tests (including retained stubble from previous year) from each site was analysed for presence of Rhizoctonia, Fusarium and Pratylenchus in waterlogged and non-waterlogged areas.
On the 21st May 2018, the trial was sown to feed wheat variety Sunlamb at 90 kg/ha with 100 kg of Agstar Cu, Zn, Mn, and 25 kg MOP applied at seeding. This totalled 14.3 units of N, 14.0 units of P, and 9.0 units of S. Post seeding nitrogen applications for each treatment are shown in Table 1, Figure 1 shows location, design and dipwell positioning.
