Results of the study of pH and organic matter in the surface soil of Ulaanbaatar

Proceedings of the Mongolian Academy of Sciences, 2021
This work summarizes the results of a study into such important urban soil parameters as soil actual (pH) and potential acidity (pH) and soil organic matter content (SOM) in the surface soil of Ulaanbaatar. The soil pH in Ulaanbaatar is slightly alkaline,

Soil acidity as affecting micronutrients concentration, nitrato reductase enzyme activity and yield in upland rice plants

Semina: Ciências Agrárias, 2013
The lowest grain yield of rice under no-tillage system (NTS) in relation to the conventional system may be due to the predominance nitrate in the soil and the low nitrate reductase activity.

Long-Term Application of Pig Manure to Ameliorate Soil Acidity in Red Upland

Agriculture, 2023
While the application of manure to improve soil quality has attracted attention, the effect of pig manure application rates on soil acidity remains poorly understood. In this study, we analyzed the changes and correlations between soil acidity, pH buffer
