“…According to Heydarnezhad [ 41 ], when sulfur elements and sulfur-oxidizing bacteria were added to calcareous soil, the solubility of phosphorus, zinc, iron, etc. increased significantly as the soil pH decreased, while EC increased [ 42 , 43 , 44 , 45 , 46 ].…”

Peat moss is an organic substance corroded by sphagnum moss and has a pH of 3.0–4.0. Elemental sulfur is sulfated and oxidized by the action of bacteria to become sulfuric acid. These biological factors can alter the soil environment. Blueberries require soil with a pH of 4.5–5.2 and high organic matter content. In this experiment, we investigated whether different treatment rates of peat moss, elemental sulfur, and sulfur-oxidizing bacteria affect changes in soil pH, physicochemical properties, and electrical conductivity. We detected strong changes in soil pH as a reaction to the supply of peat moss, elemental sulfur, and sulfur-oxidizing bacteria. The pH of the soil when peat moss and elemental sulfur each were supplied was reduced. In addition, the pH decreased faster when elemental sulfur and sulfur-oxidizing bacteria were supplied together than elemental sulfur alone, satisfying an acidic soil environment suitable for blueberry cultivation. In this experiment, it is shown that peat moss, elemental sulfur, and sulfur-oxidizing bacteria are suitable for lowering soil pH. It was demonstrated that when elemental sulfur and sulfur-oxidizing bacteria were treated together, the pH decreased faster than when treated with peat moss. It could be economically beneficial to farmers to use elemental sulfur and sulfur-oxidizing bacteria, which are cheaper than peat moss, to reduce the pH of the soil.

In agricultural highland, soil properties change over time due to soil management methods, soil erosion, and cultivation. The objective of this study was to investigate the differences in soil properties according to land management in agricultural highland. As a result of the soil analysis, Anbandegi, Maebongsan, Yeongwol, and Jeongseon, located near the top of the mountain, had low bulk densities, and organic matter, CEC, exchangeable cation, water stable aggregation rate, and dehydrogenase activity, were relatively higher than those of Daegwallyeong and Punch bowl. In the Daegwallyeong and Punch bowl, saprolite soil was periodically piled to replace eroded top-soil, and as a result, soil characteristics differed significantly from those located near the top of the mountain. In the principal component analysis result, organic matter showed the largest eigenvalue in PC1, and pH was selected as PC2. The distribution of soil clusters by sampling point was PC1, and Daegwallyeong and Punch bowl were classified differently from highland areas near the top of the mountain, and coastal basins and Daegwallyeong were classified by PC2. In conclusion, highland soil showed different soil properties for each region, which was the result of differences according to the soil management methods. And considering the relationship between soil characteristics, it was confirmed that organic matter was the most important factor in the soil management methods.

The photosynthesis, productivity, and mineral content of Chinese cabbage (Brassica campestris subsp. napus var. pekinensis cv. Detong) grown in different soil types on Jeju Island were investigated to develop soil-crop system management, with the goal of increasing crop productivity and quality. The soils were black volcanic ash soil (BS), very dark-brown volcanic ash soil (VDBS), and darkbrown non-volcanic ash soil (DBS). VDBS had a pH of 5.87, relatively close to the optimal pH range for Chinese cabbage cultivation, and slightly higher than the pH of BS and DBS; it had high contents of organic matter, available P2O5, and exchangeable cations (K, Ca, Mg, etc.). Growth of the cabbage head including height, diameter, fresh weight, leaf numbers, and leaf area were greater in Chinese cabbage grown in VDBS compared to BS or DBS. Root biomass was also greater in VDBS, although root length did not differ significantly among soil types. However, the soluble solid content was lower in VDBS than in BS or DBS. The maximum photochemical efficiency (F v /F m ) of photosystem II was slightly higher in VDBS and DBS, although it had stable values ≥ 0.8 in all three soil types. The SPAD values did not differ significantly and were ≥ 55 in all three soil types. The water-use efficiency (WUE) was slightly higher in VDBS, although the maximum photosynthetic rate (A) and dark respiration (R d ) did not differ among soil types. Of the mineral elements in cabbage head, total nitrogen was lower in VDBS than in BS and DBS. However, all macronutrients, except Mg, and micronutrient Cu were slightly higher in VDBS than in the other soil types. These results suggest that the relatively favorable soil conditions of VDBS (suboptimal pH, high mineral content, etc.) and high water-use efficiency of Chinese cabbage favor head growth and its nutritional value. VDBS was suitable for cultivating Chinese cabbage, considering productivity and product quality, such as its size, weight, and mineral content.
