Notes:
Summary An experiment involving three zinc treatments and two rice varieties in seven adjacent fields along a toposequence of soils with increasingly poor drainage downslope confirmed that zinc deficiency is most severe in the most poorly drained areas. Lack of soil aeration during the dry season and high organic matter contents in the wettest fields which are subjected to upwelling of artesian water, seem to be mainly responsible for the very low availability of zinc. High pH and high levels of dissolved magnesium bicarbonate may contribute to the disorder, but do not explain the variation in zinc deficiency along the toposequence.
