Aims:
To investigate the effect of deep ripping and gypsum on root and plant growth of wheat, canola and lentils.
Aims:
Experiments were conducted on two different soil types to test if (a) amelioration of these subsoils with a mix of gypsum and organic peat would increase the ability of the soil to hold more ‘plant available’ water and (b) if this extra water availability, would assist crops to achieve a better yield.
Aims:
To investigate amelioration of subsoil acidity through topdressing higher rates of lime and combining lime with gypsum.
Aims:
A three year deep ripping experiment was conducted on a highly acidic soil to test how effective a range of inorganic soil amendments were to ameliorate subsoil acidity and improve crop growth and yield.
