“…Soil properties are known to affect the occurrence of potato scab. The disease-suppressing factor in soil has been reported to be soluble Al and not the soil pH (Mizuno and Yoshida 1993;Mizuno et al 1998b), which was confirmed in this study.…”

“…Root rot of common bean (Phaseolus vurgaris L.) caused by Fusarium solani f. sp. Phaseoli (Furuya et al, 1996) and common scab of potato (Solanum tuberosum L.) caused by Streptomyces scabies (Mizuno and Yoshida, 1993) are common in Hokkaido, Japan where allophanic Andosols are widely distributed. Suppression of these soil-borne pathogens was reported in non-allophanic Andosols because the higher levels of exchangeable and associated aqueous Al inhibit these pathogens.…”

Nature, properties and function of aluminum–humus complexes in volcanic soils

Andosols (or Andisols) possess several distinctive properties that are rarely found in other groups of soils. These properties are largely due to the dominance of short-range-ordered minerals (allophane, imogolite and ferrihydrite) and/or metal-humus complexes (Al/Fe-humus complexes) in their colloidal fraction. While several papers have extensively reviewed the nature and properties of short-range-ordered minerals, there is no comprehensive review of the genesis, characteristics and management implications of Al-humus complexes, the dominant form of active Al in non-allophanic Andosols. In this review, we survey the chemical characteristics of Al-humus complexes and discuss the pedogenic environment favoring their formation in non-allophanic Andosols. The role of Al-humus complexes in carbon cycling and soil organic carbon accumulation is emphasized as an important mechanism controlling organic dynamics in Andosols. While non-allophanic Andosols share many common properties with allophanic Andosols, they display several distinct characteristics associated with Al-humus complexes, such as strong acidity and high exchangeable Al content that impair agricultural productivity due to Al phytotoxicity. Thus, we focus on the role of Al-humus complexes in regulating aqueous Al 3+ solubility and release/retention kinetics, Al phytotoxicity, phosphorus dynamics, and suppression of soil-borne diseases. Knowledge of these soil properties as related to Al-humus complexes is necessary to develop effective soil management practices to assure sustainable agricultural productivity in non-allophanic Andosols. Finally, future research needs are identified concerning the role of Al-humus complexes in regulating soil biogeochemical processes.

“…Soils from the fields with high copy numbers were treated with the antagonistic microorganism and/or fertilization amelioration, and we investigated the effects of these treatments on scab disease control. The fertilization amelioration method used was demonstrated by Mizuno et al 14) as a measure against potato scab disease in Hokkaido 15) . This method uses ammonium sulfate as the nitrogen component of the chemical fertilizer applied to the planting rows, and mixes the phosphorus and potash components with the soil all over the field.…”
