There is a potential for using sulfur waste in agriculture. The main objective of this study was to design a granular fertilizer based on waste elemental sulfur. Humic acids and halloysite were used to improve the properties and their influence on soil properties. This is the first report on the use of proposed materials for fertilizer production. The following granular fertilizers were prepared (the percentage share of component weight is given in brackets): fertilizer A (waste sulfur (95%) + halloysite (5%)), fertilizer B (waste sulfur (81%) + halloysite (5%) + humic acids (14%)), fertilizer C (waste sulfur (50%) + halloysite (50%)) and fertilizer D (waste sulfur (46%) + halloysite (46%) + humic acids (8%)). Basic properties of the obtained granulates were determined. Furthermore, the effect of the addition of the prepared fertilizers on soil pH, electrolytic conductivity, and sulfate content was examined in a 90-day incubation experiment. Enrichment with humic acids and the higher amount of halloysite increased the fertilizer properties (especially the share of larger granules and bulk density). In addition, it stabilized soil pH and increased the sulfur content (extracted with 0.01 mol·L−1 CaCl2 and Mehlich 3) in the soil.

Liming of six acid soil samples in an incubation experiment with rates to raise the soil pH to 6.0 or above eliminated Al soluble in 0.01 M CaCl2, reduced soluble Mn and Zn, increased NO3-N markedly, and at the highest pH increased the amounts of NaHCO3-soluble P in some of the soils. In corresponding pot experiments, liming increased the yield of alfalfa and in three of the soils the yield of barley also. Liming reduced the concentrations of the metals in the plants and at the highest pH tended to increase the P content of the plants. Liming to a pH of about 5.3 eliminated or greatly reduced soluble Al and the soils were base saturated as measured by the replacement of Al, Ca, and Mg by a neutral salt. There was some evidence that liming to reduce soluble Al and possibly Mn was beneficial for plant growth. Gypsum increased the concentrations of Al, Mn, and Zn in 0.01 M CaCl2 extracts of the soils whereas phosphate reduced them. The changes in the Mn content of the plants following these treatments were in agreement with the amounts of Mn in the CaCl2 extracts.

The effect of elemental sulfur on some chemical soil properties and wheat grown was studied by two performing experiments, under high terrace soils of northern region of the Sudan. First experiment (incubation experiment) was executed to quantify the rates and application time of elemental sulfur to be applied in the field experiment. It consisted of five rates of elemental sulfur (0, 165, 330, 495 and 660 kg sulfur feddan-1) and five application times (2, 4, 6, 8 and 10 weeks). In the second experiment (field experiment), two wheat varieties (Wadi Elneel and Debeira), three sulfur rates (0 kg S feddan-1, 495 kg S feddan-1 and 660 kg S feddan-1) and three application times (0, 5 and 7 weeks) were arranged in split plot design with four replications. Wheat varieties were assigned to the main plots and the combination of the rates and time application to the sub plots. Results obtained from the incubation experiment indicated differences in soil pH among treatments. Application of elemental sulfur decreased soil pH in each of the two experiments. The effect of elemental sulfur on wheat grain yield and the other studied yield components was not limited the plant height and the 1000 seeds weight. The nitrogen content of the plant tissue was affected by the applied elemental sulfur. Application of 495 kg sulfur feddan-1, 6 weeks before sowing gave the lowest soil pH (7.8) and the least available phosphorus compared to other treatments.

A field study was conducted at 4 sites in central Saskatchewan to examine the oxidation rate of elemental S and its influence on soil pH. Finely divided S (approximately 7-μm diameter) was applied at a rate of 200 kg ha−1 to soil cores in aluminum cylinders. Three entire cores from each site were removed and analyzed for sulfate content and soil pH four times during a 16-mo period. All four soils exhibited significant oxidative activity. Twenty-three to forty-five percent of applied S was recovered as sulfate 10 wk after application. Sulfate concentrations recovered in the soil profiles declined after approximately 1 yr, partly due to leaching losses. Fertilizer-derived sulfate was most persistent in soils of finer texture. In the coarse-textured soils, most of the fertilizer-derived sulfate was apparently leached from the soil profile by the end of the 16-mo period. Soil pH was marginally reduced by oxidation following the application of elemental S but differences were no longer statistically significant at the last sampling time. Field incubation with elemental S substantially enhanced subsequent oxidative activity in three of the soils, suggesting that an initial application of elemental S fertilizer would enhance the effectiveness of subsequent applications. Substantial oxidation activity occurs in Saskatchewan soils even under the less than ideal conditions prevalent in this climatic region. It was concluded that elemental S in a finely divided form has strong potential as an effective fertilizer S source if appropriate fertilization strategies are adopted to maximize oxidation rate or compensate for delays in plant-available S release.

Heterotrophic and autotrophic sulfur-oxidizing populations in 35 Saskatchewan agricultural soils were enumerated. These populations included heterotrophs that produce thiosulfate and or sulfate during elemental sulfur (S°) oxidation, heterotrophic thiosulfate oxidizers, and autotrophic thiosulfate oxidizers. Populations of Thiobacillus thiooxidans and T. ferrooxidans were not detected in any of the soils tested. Heterotrophs that oxidized S° to thiosulfate as the major oxyanion were the most abundant oxidizers enumerated (107–108 cells g−1) and were found in all soils. Autotrophic thiosulfate-oxidizers were detected in 10 of the soils surveyed. Heterotrophic S° and thiosulfate-oxidizing populations exhibited positive trends with soil pH, total-S, hydriodic reducible-S, and clay content, whereas populations of autotrophic thiosulfate oxidizers were negatively correlated with these factors and positively related to sand content and increasing C:S ratios. In soils containing autotrophic thiosulfate oxidizers the amount of thiosulfate relative to sulfate detected was reduced although no effect on S° oxidation rate was detected. Amendment of 15 selected agricultural soils with 0.5% S° significantly reduced total heterotrophic populations, whereas autotrophic thiosulfate oxidizers increased from undetectable levels to 104 cells g−1. Therefore most Saskatchewan soils contain abundant populations of heterotrophic S° oxidizers, and populations of autotrophs that respond to S° applications. Key words: Sulfur oxidation, autotrophic sulfur oxidizers, heterotrophic sulfur oxidizers, soil properties

Abstract. Adanan IC, Wasli ME, Perumal M, Ying HS. 2020. Characterization of soil properties in relation to Shorea macrophylla growth performance under sandy soils at Sabal Forest Reserve, Sarawak, Malaysia. Biodiversitas 21: 1467-1475. A study was conducted in the Sabal Forest Reserve, Sarawak, to characterize soil properties in terms of soil morphological and physicochemical properties under sandy soil at the reforestation site in comparison with High Conservation Forest soil as well as to assess growth performance of planted S. macrophylla under the sandy soil. Study sites with the size of 25 m x 25 m were established under reforestation sites (Early Establishment of Reforestation Site (ER) and Late Establishment of Reforestation Site (LR)) as well as the High Conservation Forests (HCF-1 and HCF-2). The results from soil morphological properties showed that the soils in ER and HCF-2 plots resemble Saratok series while soils in LR and HCF-1 plot were classified into Buso series. As for soil physicochemical properties, soil in all study sites were strongly acidic in nature with pH (H2O) value less than 5.00 with sandy (more than 55%) at both surface and subsurface soil. The survival percentage of planted S. macrophylla in ER and LR plot was 65 % and 56%, respectively. Long term monitoring on soil properties and growth performance of planted S.marophylla tree are essential in order to continuously provide information on the status of reforestation activity.

The objective of this paper was to investigate the molecular characterization of soil organic matter fractions (humic substances (HS): fulvic acids-FAs, humic acids-HAs, and humins-HNs), which are the most reactive soil components. A wide spectrum of spectroscopic (UV–VIS and VIS–nearIR), as well as electrochemical (zeta potential, particle size diameter, and polydispersity index), methods were applied to find the relevant differences in the behavior, formation, composition, and sorption properties of HS fractions derived from various soils. Soil material (n = 30) used for the study were sampled from the surface layer (0–30 cm) of agricultural soils. FAs and HAs were isolated by sequential extraction in alkaline and acidic solutions, according to the International Humic Substances Society method, while HNs was determined in the soil residue (after FAs and HAs extraction) by mineral fraction digestion using a 0.1M HCL/0.3M HF mixture and DMSO. Our study showed that significant differences in the molecular structures of FAs, Has, and HNs occurred. Optical analysis confirmed the lower molecular weight of FAs with high amount of lignin-like compounds and the higher weighted aliphatic–aromatic structure of HAs. The HNs were characterized by a very pronounced and strong condensed structure associated with the highest molecular weight. HAs and HNs molecules exhibited an abundance of acidic, phenolic, and amine functional groups at the aromatic ring and aliphatic chains, while FAs mainly showed the presence of methyl, methylene, ethenyl, and carboxyl reactive groups. HS was characterized by high polydispersity related with their structure. FAs were characterized by ellipsoidal shape as being associated to the long aliphatic chains, while HAs and HNs revealed a smaller particle diameter and a more spherical shape caused by the higher intermolecular forcing between the particles. The observed trends directly indicate that individual HS fractions differ in behavior, formation, composition, and sorption properties, which reflects their binding potential to other molecules depending on soil properties resulting from their type. The determined properties of individual HS fractions are presented as averaged characteristics over the examined soils with different physico-chemical properties.
