“…When Mn + + is plotted against the redox potential of the soil (Figure 1 f), a fairly uniform curve is obtained (some cyclic tendency was observed in the actual data), thus indicating that the Mn + + + ~ Mn + + reaction is strictly chemical in nature. This may explain the well documented relationship between ferrous iron and reduction of manganese ( 2,3,5). Since ferric iron is believed to be the major electron acceptor in the reducing soil, a higher percentage of ferrous iron would create a lowereci redox potential.…”

Synopsis Incubation of a Toledo clay loam soil revealed that as soil water is increased above field‐capacity the soil environment is changed from oxidizing to reducing conditions. This transformation occurred in about five days. Thus, a soaking rain could create an healthy environment for plant growth, unless drainage is prompt. The formation of the genetic soil profile can also be partially explained by this rapid reduction.

“…Ferrous sulphate is acidic in nature which will increase the soil acidity if the treated water and sludge is apply for irrigation [18][19]. Nevertheless, the pH of aerobic feed water is in alkaline range that will have buffering effect to the lowering of pH when applying the ferrous sulphate dosage for the physiochemical treatment.…”

A B S T R A C TThe palm oil milling industry in Malaysia will be imposed with more stringent treated waste water discharge requirement from currently at BOD of 100 ppm to BOD of 50 ppm and gradually to BOD of 20 ppm. Study was conducted to use Ferrous Sulphate as more economical coagulant to reduce the biological load for tertiary treatment in palm oil mill effluent treatment at laboratory and pilot scale facility to comply with the proposed new requirement. The feed water that was aerobically treated POME with BOD of below 100 ppm was treated with various dosage of ferrous sulphate, from 250 to 2250 ppm. It was found that at laboratory jar-test, the required ferrous sulphate dosage to meet BOD-50 ppm requirement was at 750 ppm while BOD-20 ppm requirement was achieved when the ferrous sulphate dosage was at 1,750 ppm and did not produce hazardous activated sludge. The laboratory findings was scaled-up to pilot scale facility with the capacity of 7 ton/hour to evaluate the physicochemical tertiary treatment based on continuous system. Ferrous sulphate dosage at 1,000 ppm and 1,750 ppm were able to comfortably comply with the discharge limit of BOD-50 ppm and BOD-20 ppm, respectively.

“…Additional iron was not given because it acts as an antagonist of manganese (LÖHNIS 1951, GUPTA 1972. In fact, iron may also promote the uptake of manganese by the plants by reducing manganese oxides (BOKEN 1955(BOKEN , 1956(BOKEN , 1957. Four yields were harvested from the pot experiment.…”

The aim of the study was to determine the plant-available manganese in the soil and to study which factors regulate the plant-available manganese. The material consisted of 193 mineral soils and 17 organogenic soils. Oats (Avena saliva L.), Italian ryegrass (Lolium multiflorum Lam.) and turnip rape (Brassica campestris oleifera L.) were used as the test plants in the pot experiments. A cation exchange resin method was developed for extracting soil manganese. The method enabled both exchangeable and reducible manganese to be determined. Exchangeable manganese comprised the manganese which was freely present in the soil solution in cationic form, and the manganese in cationic form which could be exchanged from the soil. Reducible manganese was the manganese reducible to the oxidation state, Mn2+, by the action of hydroquinone, hydroxylammonium chloride or ascorbic acid. The content of exchangeable manganese in the soil explained 33,7 % of the variation in the manganese content of the first yield of ryegrass. The greater the number of yields harvested, the smaller was the significance of the content of exchangeable manganese in the soil as an independent variable. On the other hand, when the content of reducible manganese in the soil was used as the independent variable, then the greater the number of yields harvested, the better it explained the variation in the manganese content of the yield. The content of manganese reduced by hydroxylammonium chloride explained 68,6 % of the variation in the manganese content of the fourth yield. The contents of exchangeable manganese and manganese reducible by ascorbic acid explained 73,4 % of the variation in the manganese content of the roots. The pH, the organic carbon content and the content of hydroquinone-reducible manganese in the soil explained 67,0 % of the variation in the content of exchangeable manganese in the plough layer of the mineral soils. The content of "total" manganese in the plough layer of the mineral soils explained 27,6 % of the variation in the content of ascorbic acid-reducible manganese. The plant stands increased the content of exchangeable manganese in the soil and decreased the redox potential of the soil in comparison to the incubated soils. The content of exchangeable manganese started to increase when the redox potential of the soil fell below 0,59 V. Adding glucose promoted the reduction of manganese in the soil, reduction appearing to be both biological and non-biological in origin. Soil moisture increased the content of exchangeable manganese when the moisture was higher than the field capacity. Liming decreased the content of exchangeable manganese in the soil more than would have been expected on the basis of the change in pH values. The manganese content and manganese uptake of the crop were also reduced. Adding large amounts of manganese (Mn 51,5 kg/ha*20 cm) did not prevent liming (calcite 14 t/ha*20cm) from reducing the manganese content of the yield.
