Sulfur deficiency vs. control-Rice

Symptoms
Uniform pale green discoloration on young leaves, proceeding to complete yellowing (starting from leaf tip).

Reasons
Sulfur deficiency. Nitrogen deficiency may cause similar chlorosis, but occurs on older leaves first. Plant analysis can help to identify S deficiency. S deficiency more likely occur in: - Soils with low organic matter status - Highly weathered soils containing large amounts of Fe oxides. - Sandy soils, which are easily leached - In areas located far away from industrial centers. - After intensive cropping and the use of S-free fertilizers. - After intensive cropping and removing or burning the straw.
