“…Soils with high concentrations of carbonates and bicarbonates are highly buffered against acidification (Rogovska et al, 2007). The buffering effects often take place more slowly than the formation of sulfuric acid from elemental S (Deubel et al, 2007). When the original S recommendation for sugarcane of 448 kg S ha −1 was established years ago, soil pH in the EAA was considerably lower.…”

“…Soils with high concentrations of carbonates and bicarbonates are highly buffered against acidification (Bloom 2000;Rogovska et al, 2007). The buffering effects often take place more slowly than the formation of sulfuric acid, therefore, a later increase of soil pH is possible (Bloom 2000;Deubel et al, 2007). A limited reduction in soil pH after S application was observed in other studies of calcareous soils (Hassan and Olson 1966).…”

“…However, soil pH dropped slightly at 2 months after S addition for the highest S application rate and increased thereafter from 6.0 to 6.4 at the end of growing season, which indicated a lag effect of soil buffering. The limited effect of acidification may result from the relatively low rates of S application and from the high buffering capacity of this organic soil (Bloom 2000;Jaggi et al, 2005;Deubel et al, 2007). Soils with high concentrations of carbonates and bicarbonates are highly buffered against acidification (Bloom 2000;Rogovska et al, 2007).…”

Nutrient export from the Everglades Agricultural Area (EAA) has been implicated in causing sulfur (S) enrichment of Everglades wetlands. However, quantification of the S budget and transformations in EAA soils is inadequate. The objective of this study was to quantify various S fractions and investigate how elemental S amendment affects S dynamics in EAA soils. Reduced S compounds were not detected in soil before elemental S application. Organic S was the major form of S, comprising 87% of total S, followed by extractable SO 4 -S (13%). Extractable SO 4 -S for soils receiving 448 kg S ha j1 was 36%, 131%, 201%, and 270% higher than for unamended soils at 2, 6, 9, and 13 months, respectively. Elemental S was significantly higher in soils receiving 448 kg S ha j1 (482 mg kg j1 ) than in soils receiving 224 (111 mg kg j1 ) and 112 kg S ha Y1 (55 mg kg j1 ) and unamended soil (0 mg kg j1 ) at 2 months after S application. Similar to extractable SO 4 -S, elemental S significantly decreased during the growing season. Sulfur application did not affect the sulfatase activity, however, mineralizable S increased concurrently with S application rate, and the effects continued throughout the growing season. This result was largely attributed to the oxidation of the applied elemental S. Our results suggest that large-scale S application in the EAA soils is likely to increase SO 4 2j concentrations in soils, which poses a potential risk of SO 4 2j export to sensitive Everglades wetlands.

Elemental S is used as an amendment for Everglades Agricultural Area soils of south Florida to decrease pH and increase P availability to crops. Our objectives were to determine how S application altered phosphorus distribution and availability in organic soils under sugarcane cultivation. Soils were sampled four times during the growing season at 2, 6, 9, and 13 months after sulfur application and subjected to chemical P fractionation. Sulfur application had minimal effect on soil pH and thus generally failed to increase P supply to sugarcane during the entire growing season at the application rates tested due to the high soil buffering capacity against acidification. Yet, a significant reduction in soil pH did increase P concentrations in labile P and Fe-Al bound P fractions at 2 months for the highest S rate. Concentrations of labile P and Fe-Al bound P declined during the sugarcane growing season. The size of Ca-P fraction remained unchanged during the early season but significantly decreased at the end of the growing season. Humic-fulvic acid P fluctuated seasonally, averaging 143, 172, 139, and 181 mg P kg -1 for 2, 6, 9, and 13 months, respectively. Residual P fluctuated in a contrasting pattern to humic-fulvic acid P and contributed approximately 50% to the total P. Overall, S application did not result in large P accumulation in labile pools, thus S application does not appear to enhance potential P export from fields into wetlands.
