WHY CTF ?(No-Till)<br />
• Conventional (not sustainable)<br />
- Degrading soil conditions<br />
- Labour<br />
- Economical ratio’s<br />
• Opportunity to upgra<strong>de</strong> equipment<br />
• Rob Ward<br />
- no-till information
Sustainable?<br />
• Topsoil loss<br />
• Run off<br />
• Erosion<br />
• Nutrients
compaction
Wheat planting 1990’s
Rob Ward first visit Dec 1998<br />
r
Beginning of no-till 1999
Issues with implementation of<br />
CTFand no-till<br />
• Capital investment<br />
• Row spacing and layout (9 or 12m )<br />
• Planting next to stubble<br />
• Extending front axle’s<br />
• Hea<strong>de</strong>r front width and unloading<br />
• Cotton into system (Opportunity crop)<br />
• Local <strong>de</strong>alers (1999 no knowledge)
Capital investment<br />
• New equipment<br />
• RTK Base station, etc
9 or 12m<br />
• Wi<strong>de</strong>r – lest equipment (33% )<br />
• Compaction<br />
- 9 m (11.5%)<br />
- 12 m (8.6%)<br />
• Cotton (opportunity crop)<br />
- 9m (OK)<br />
- 12 (2 extra wheel tracks with picking!!)<br />

Achievement<br />
• Soil improvement<br />
• Equipment upgra<strong>de</strong> over time<br />
• Efficient use of capital<br />
• Easy to add on operations<br />
• Increased yields<br />
- grain (40-60%)<br />
- Cotton (80-100%)<br />
• Fuel use 30lt/ha (60% less)<br />
• No cattle on stubble<br />
• Unfortunately chemical use increased
After thun<strong>de</strong>rstorm<br />
(minimum run off) 2013
Upgra<strong>de</strong>d machinery<br />
Productive use of machinery
Optimum use of capital
Wheat planting 2013
CTF<br />
Unload in the run<br />
(25-30% increase efficiency)
CTF and manure spreading
N application on cotton
Sunflower
Sorghum
Dryland cotton
Future<br />
• Flotation tyres on self propelled sprayers<br />
(need to cut on chassis ?)<br />
• Sprayers 36m boom (Extending JD 24m)<br />
• Rubber tracks on hea<strong>de</strong>rs/chaser bin<br />
• Mulching cotton, irrigated maize stubble in<br />
12m layout (manufacturing at the moment)<br />
• Dropping chaff in wheel tracks
Prototype dropping chaff in wheel tracks
CTF rest of RSA<br />
• Changing direction every season<br />
• Challenger tractors on sandy areas<br />
• No hea<strong>de</strong>rs/chaser on CTF<br />
• 2m tramlines with hea<strong>de</strong>rs on its own<br />
• No till area increasing every year
