ABSTRACT
Treat area with systemic non-selective herbicide one month before starting cultivation operations; rip up subsoil using subsoiling machine to a depth of 250mm below topsoil at 1.20m centres in light to medium soils; rotavate to 200mm deep in two passes; cultivate with chain harrow; roll lightly; clear stones over 50mm By tractor 100m² 11.50 As above but carrying out operations in clay or compacted gravel 100m² 13.00 As above but ripping by tractor rotavation by pedestrian operated rotavator; clearance and raking by hand; herbicide application by knapsack sprayer 100m² 29.00 As above but carrying out operations in clay or compacted gravel 100m² 30.00
