Title: Study pH Variation of Northeast Black Soil and Its Influencing Factors by Soil Removal Method
Abstract: Soil pH is an important indicator in assessing soil quality.pH variation and its influencing factors of black soil was studied in the same environmental condition by a soil removal based on a long-term field experiment,in which the samples were collected from south to north of northeast black soil zone with five different organic matter contents and moved to Hailun Agricultural Ecology Experimental Station,CAS.The results showed: black soil pH varied dynamically during whole growth period,their variation ranged from 0.1 to 1.2.Fertilizer application and soil organic matter contents greatly impacted black soil pH.There was a significant negative relationship between soil moisture and black soil pH.The soil pH was significantly influenced by precipitation,not significantly by rainfall pH.
