Scientists are pleased with the results of repairs to earthquake-damaged farmland in Canterbury.
Some farmland suffered extensive damage in the 7.1 magnitude quake in September, with liquefaction, cracks of up to a metre wide, and several metres deep, displaced fences and damage to grain silos and milking sheds.
A soil scientist at Lincoln University, Dr Peter Almond, says research work it carried out a month after the quake to repair land that had been damaged, particularly by liquefaction, has proved to be successful.
He says once-flat paddocks that were littered with mounds of sand after the quake are now lush with grass.
