Lance Wise farms 1650 hectares on Queensland\u2019s Darling Downs. The farm grows sorghum, wheat, barley, chickpeas and mung beans, all of which are cropped for grain.
Though production varies from season to season, yields average 4t\/ha yield for sorghum, 2t\/ha for wheat and barley, 1.5t\/ha for chickpeas and 1t\/ha for mung beans. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Lance Wise has four Kelly harrows (two 30ft and two 40ft models), which he uses on his own farm as well as renting them out to others as part of his dry hire business. Two machines (one of each model) are fitted with CL1 Disc Chain front and rear, for a more moderate and versatile approach. The other two machines have CL2 Disc Chain front and Spiked Disc Chain on the rear; the sharp-edged CL2 discs provide more aggressive weed control, while the spiked discs leave a coarser finish which is more resistant to erosion. Lance Wise feels that the CL2\/ Spiked Disc combination is the best fit for his farm\u2019s soils.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Lance Wise first purchased a Kelly harrow as a way to supplement his weed control. He uses the disc chain together with herbicide as a cheap \u2018double knock\u2019 that doesn\u2019t contribute to chemical resistance. This process helps him to kill a higher percentage of weeds at a lower cost.
The Kelly harrow has been effective at controlling herbicide resistant feathertop Rhodes grass and fleabane, especially on Wise\u2019s black clay soils.
Wise has found that the Kelly harrow kills 85-90% of weeds when used before spraying herbicide. After a light spray though, weed kill goes up to 99%.
Since integrating the Kelly into his weed control program Wise has been able to cut out a total of 3-4 sprays per year and weed pressure on his farm has decreased significantly. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

The Kelly Diamond Harrow plays a key role in multiple sustainable processes on the Wise farm. It\u2019s used to incorporate stubble into the topsoil, retaining carbon and minimising the loss of organic matter. In the same pass, the Kelly harrow pulls out 85-90% of weeds, reducing the need for herbicides.

Wise also uses the Kelly harrow to help soil moisture levels. Improving water retention is the biggest challenge for Wise, who has begun to use sub-soil ripping to increase water holding capacity. By working to a depth of 35-40cm, he\u2019s been able to improve moisture levels in the soil and break up compaction. The Kelly harrow aids in this process by levelling the field after ripping, mitigating damage to the seedbed and increasing the tilth. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
