Organic soil pH influenced by drying and salts, impacting crop yields.
The researchers studied how soil pH in organic soils is affected by drying and salt concentration. They found that the pH of field-moist soils was higher than oven-dried soils, and the type of solution used for testing influenced the pH values. Different soils responded differently to treatments. The amount of hydrogen, bases, and liming affected soil pH. Liming had a significant impact on soil pH shortly after application but less so the following year. Soil pH varied throughout the growing season, with more variability in treated soils. The amount of reacted limestone increased with higher application rates.
