Over winter 2019, the QFH Multiparts Productive Landcare Demonstration Project is undertaking a trial testing the establishment of a range of pasture species on salt affected land.
Plants can and will grow on salt affected land – sequestering carbon into the soil, protecting against erosion and providing a valuable food source for livestock – buuuut it’s a little tricker than on fresh soil. The amount of salt present, risk of water logging, pH constraints and degraded organic content can make choosing the most suitable species – and getting them to grow – more challenging.
Three sites ranging from 8 – 18ha each have been selected for the trial, and soil samples taken. A portion of each site was scarified prior to seeding. With input from pasture-guru Neil Ballard, the following species have been selected and allocated to each site:
- Italian Ryegrass
- Scimitar Medic
- Rose Clover
- Silverosa Lucerne
- Eliza Seradella
Sowing took place in May 2019. The trial was assessed later in the season using visual assessment, food on offer (FOO) and greenness. A field walk was held in October 2019 to view the trial sites and share results.
