deep ripped soil

Catalogue: GRDC Media
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..

Wet conditions can cause headaches for growers at harvest time, but a silver lining may be the opportunity to use deep cultivation to alleviate compacted sands... Research has also shown that the use of CTF techniques on deep-ripped soils can save fuel and deliver crop yields about 10 per cent higher compared with those from cultivated areas where CTF is not used... Dr Blackwell said some growers were finding they could conserve fuel and reduce soil clod size by using deep rippers with 'shallow leading tynes' at the front of the machine and deeper tynes at the back, when they needed to rip to 500 millimetres...
