Crops on deep ripped soils show promise in dry season

Plain text source: 
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...
