Abstract: Hydrogen sulfide (H2S) toxicity is an increasingly problematic physiological disorder reported in certain Arkansas rice (Oryza sativa L.) fields. Though the exact causes of this disorder are unknown, one contributing suspect is use of ammonium sulfate (NH4)2SO4 fertilizer. A greenhouse study was designed to investigate the physical and chemical differences in four soils in Arkansas where this disorder regularly occurs (H and HR-Y) and never has been reported (HR-N and PTRS) and to investigate the effects of different rates of (NH4)2SO4 fertilizer on those soils. According to the Mehlich 3 soil test report, few major differences were present between soils prone to H2S toxicity and those that are not. With Zn deficiencies appearing in PTRS and HR-N, several fact... view moreĀ»
