Question

    Which factor primarily contributes to “sorghum

    sickness” observed in fields after harvesting the crop?
    A High nitrogen content Correct Answer Incorrect Answer
    B Wide carbon to nitrogen (C:N) ratio Correct Answer Incorrect Answer
    C High phosphorus content Correct Answer Incorrect Answer
    D Excessive root biomass Correct Answer Incorrect Answer

    Solution

    “Sorghum sickness” is caused by the wide C:N ratio of sorghum residues, which leads to microbial immobilization of nitrogen, resulting in nitrogen deficiency for subsequent crops.
