An analysis of the soil and plant tissues was undertaken to ascertain the effect that land irrigation with pulp mill effluent has on nutrient uptake and element balance of tree seedlings. Results show that the effluent significantly increased the sodium content of both soil and tissue; however, these levels fell far below the level necessary to become detrimental to plant life, soil chemistry and soil structure. There was evidence that the increase of elements from the effluent provided positive effects in growth and plant health. There was no evidence of sodium toxicity or calcium starvation. Evidence clearly points out the value of nutrient increases from the effluent in sandy soil of low cation-exchange-capacity.
