Application of Organic Fertilizer Tithonia Plus to Control Iron Toxicity and Reduce Commercial Fertilizer Application on New Paddy Field
Hakim, Nurhajati, ., Agustian, Mala, Yanti
Ferrous toxicity is a one of the problems most often found in lowland rice systems in tropical and sub-tropical regionespecially in new paddy field (NPF) on Ultisols and Oxisols. Flooding during rice growth creates a chemicallyreduced state in soils causing reduction of insoluble (Fe3+) to soluble (...
