In a pot experiment very-acid soil liming increased the ‘Start’ spring barley yield. The plants grown on acid soil accumulated a greater amount of phosphorus in grain, straw and roots than in limed soil. Liming and nitrogen and phosphorus fertilisation enhanced the uptake and use of phosphorus by plants whose uptake was greater from triple superphosphate than from rock phosphate meal. The use of phosphorus was also greater from superphosphate than from meal, irrespective if the fertilisers applied onto acid or limed soil.
