    1. Rice for Acid Soils & Moisture Stress Arunava Pattanayak ICAR Research Complex for NEH Region Umiam, Meghalaya

    2. Acid Soil & Toxicities Soils with low pH (<5.0) results in chemical imbalances. Elements like phosphorous (P), molybdenum (Mo), magnesium (Mg) and calcium (Ca) become less available. Other elements like aluminium (Al), iron (Fe) and manganese (Mn) reach upto toxic levels. Plant sensitivity to moisture stress increases. Activity of nitrogen fixing bacteria and mycorrhizal fungi are severely hampered.

    3. Effect of aluminium toxicity Rapid inhibition of root growth Variations in relative root length and root biomass Dammaged root apex Callose formation at the root apex Thickening of primary roots Excessive branching of roots
