Contract Mouldboard Ploughing service available in South Australia
Central Hills Machinery offers a contracting service to plough ground for broadacre crops, centre pivot, potatoes, onions etc. in South Australia.
Mouldboard ploughing is a natural way of tilling the ground, and has been used for hundreds of years. It produces extremely good yield results, as opposed to discing, where the discs float over the ground, leaving an uneven surface and chopping the weeds, which generally then multiply.
We can reach around 15” to 16” depending on soil type. Generally 4” to 8 “ is a good depth for various types of sowing.
- 5 furrow linkage hydraulic
- 8 furrow Kverneland reversible
- 13 furrow hydraulic reversible
The larger 13 furrow plough is 66’ long (it’s one of the largest ploughs in Australia), and can cover a vast amount of area in a short time, especially with the 8 furrow and the 13 furrow working in unison. In order to pull these ploughs, Tony uses a 300+ horsepower Deutz and an 8-wheeler linkage versatile tractor for very heavy conditions.
The benefits of mouldboard ploughing include:
- Complete weed control without the use of pesticides. As the plough works the ground, it buries weeds that tend to spring up after harvest. The plough thoroughly inverts the soil which inhibits the growth of weeds until the following season. This spares you from the time and labour involved where weed resurgence is a frequent occurrence.
- Even depth of soil for planting. When well-adjusted, the plough automatically seeks the desired depth. The complex structure of the plough clears the ground of wheel tracks and channels left by the machinery used to harvest, which creates a more level surface, enabling seed to be sown with higher accuracy.
- Can incorporate non-wetting soils and bring clay to the surface (depending on depth).
- Removes compaction, resulting in increased productivity
- Reduced soil water repellence
- An opportunity to increase soil pH through lime incorporation
- The plough helps get rid of many of the pests that dwell on farmland. When these pests are eradicated, it provides plants with a more conducive environment for healthy growth. Minimal presence of pests also contributes towards a greater yields.
- The plough buries crop residues deeper into the ground, which enables decomposition to take place. The reduction of crop residues on the soil surface enables the soil to warm up faster. Evaporation of water is also enhanced which provide a more conducive environment for seed when it is sowed.
- The plough also buries surface manure and fertilisers. This optimises availability of nutritional content to deeper levels within the soil. It also reduces the odour of manure and fertiliser when these occur abundantly on the surface soil.
- The plough activity reduces the loss of nitrogen through volatilisation (the process whereby a dissolved sample is vaporised). More nitrogen is made available for humus to be produced from organic content. Mineral formation is also facilitated through this process.
Tony Cross has over 44 years of ploughing experience. He helped instigate the concept of mouldboard ploughing in Western Australia in 2002, and has competed in the world ploughing competitions. Tony says that mouldboard ploughing has been largely forgotten in SA, with the perception that it ruins the soil and the ground can’t be ploughed shallow, however this is totally incorrect. Mouldboard ploughing is a must for heavy cropping ground to turn the soil over, as much of the ground has become chemical-resistant, and farmers have to use 2 or 3 times the rate of chemicals to get a sufficient weed kill.
One farmer in the Clare Valley has been ploughing his ground for cereal crops for over 25 years with amazing results, and has achieved around 12 inches of beautiful chocolate soil with an abundance of microbiological activity with minimal use of sprays.
