Effects of Land Disposal of Pulp Mill Effluents on Plant Nutrient Uptake and Element Balance
<p>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, …
