Project Title: Increasing production on sandy soils in low and medium rainfall areas of the Southern Region
Peer Review: Rodrigo Da Silva
- Low-cost, low risk seeder-based strategies achieved valuable wheat/barley crop establishment and grain yield benefits in a severely water repellent sand in two below-average rainfall seasons.
- Edge-row/on-row sowing and 230mm deep furrow till achieved the greatest crop benefits by exploiting existing in-furrow moisture (via guided sowing) and deeper moisture (via lifting by furrow opener), respectively.
- While adoption of these strategies involves RTK guidance, liquid dispensing and compatible seeding system technologies, scope for simplified solutions to reduce practical challenges exist and their performance should be tested in farm scale demonstrations.
