Abstract
Two multifactorial trials incorporating major and trace element treatments were conducted on Te Anau yellow-brown loam. Elements included in one or both trials were calcium (lime), phosphorus, potassium, magnesium, sulphur, manganese, copper, zinc, boron, iron, and molybdenum. The main effects and two-factor interactions of the seven treatments in each trial were determined on dry matter yield, concentration of nutrients in the herbage, pasture composition, pasture vigour and percentage pointings, and soil quick tests. With the exception of phosphorus, which gave very large responses, the main effects of most elements were small. Responses in growth were obtained with phosphorus, potassium, sulphur, lime, boron, iron, and zinc, but not with magnesium or manganese. Copper depressed vigour in some instances. Many interactions were noted, particularly those affecting nutrient concentration in herbage.
