Ripper trials to overturn compaction constraints.. The brothers say soil constraints associated with compaction, including acidity, sodicity and aluminium toxicity, affect part of every paddock on their 23,000-hectare property, with yield losses of up to 0.5 tonnes/ha in some areas... "We hope the deep-ripping coupled with applying organic matter in the root zone will help crop roots to proliferate, the soil to open up and maybe also overcome some soil chemical problems," Dr Blackwell says...

Deep ripping setting new productivity benchmarks.. Brady Green spent the early part of hte year fitting inclusion plates to his deep ripper... In addition to facilitating a mid-April sowing start to canola programs, it also allowed many growers, particularly in the northern wheatbelt, to try out the new 'inclusion plates' that are fitted to deep-ripping tynes to direct loose topsoil and ameliorants, such as lime, deeper into the soil profile...

Craig Thompson bought a WEEDit precision sprayer seven years ago and says it has become a crucial tool for summer weed control... A stark drop in growing-season rainfall in WA's northern wheatbelt means growers have to get crop roots much deeper into the soil profile to access moisture.. Craig says that wheat-on-wheat, with the aid of Clearfield wheats, has simplified the system and allowed him to concentrate on the single most important element - holding on to every drop of rain that falls...

Wheat crops on the deep ripped plots have already grown roots and accessed water to a depth of 40cm below the soil surface - a much deeper level compared with the unripped plots... "In coming weeks, roots in the ripped plots may access soil water below 40cm and these crops could produce yields up to 0.5 tonnes per hectare greater than the crops on the untreated plots," CSIRO researcher Phil Ward said... "During winter, there was virtually no water uptake at 20 to 40cm in the untreated soils, but there was significant water uptake and root growth at this depth in the ripped plots," Dr Ward said...

Crops on deep ripped soils show promise in dry season..

As a general rule, a machine with a 10-tonne axle weight causes crop-constraining soil compaction to a depth of 30 centimetres... GRDC-funded research by the Department of Agriculture and Food, WA (DAFWA) is finding that deep ripping, or other soil-compaction amelioration tactics, combined with controlled-traffic farming (CTF) can help to overcome deep soil compaction and reduce the risks of re-compaction... DAFWA researcher Bindi Isbister is part of a GRDC-funded project delving into the use of deep ripping and other soil-compaction-amelioration tactics with CTF to address deep subsoil compaction...

In the central wheatbelt researchers, agronomists and growers are seeing crop yield responses of 0.5 to 1 tonne per hectare where CTF is being used in conjunction with deep-ripping on compacted sands... Department of Agriculture and Food, WA (DAFWA) officers Dr Paul Blackwell and Bindi Isbister say global research shows that where CTF is being used to help protect investments in deep-ripping or other mechanical amelioration tactics for compacted soils (such as inversion ploughing, rotary spading, delving and deep working seeding points) the benefits can last for many years... DAFWA-Liebe Group trials at Buntine are also finding wheat yield gains of up to 15 to 42 per cent - depending on the season - are possible from using CTF with deep-ripping to a depth of 35 to 40 centimetres on compacted sands in years with below-average rainfall...

"Without CTF, the benefits of these tillage systems to alleviate compaction might only last for a season or two," Dr Blackwell says...

Mullewa grower Andrew Messina is trialling a new deep-ripper that can slice 80 centimetres into the soil to crack hard pans and help overcome compaction issues... Andrew says in 12m-wide and 200m-long paddock strip trials on an area that had been mouldboard ploughed in 2011, the deep-rippers produced wheat yields of 2.7 tonnes per hectare, compared with 2t/ha from the nil-treated area and 2.3 to 2.4t/ha from a conventional deep plough (tilling to a depth of 30cm)... Andrew says the main drawback of ripping to depths below 30cm is having to use a much smaller machine - the Heliripper is about 6m wide, travels at a speed of 7 to 8 kilometres per hour and treats about 5ha/hour...
