Assessments of the soil quality can be used to evaluate sustainable soil management techniques. There is currently a considerable risk of desertification and soil deterioration in the Central region of Vietnam, which includes the province of Nghe An. The present research aims to report data on 10 physical and chemical properties of soil samples collected from the hilly zone of Nghe An province and relate their characteristics to cropping patterns.
142 composite soil samples were taken from the 0-20 cm layer of rice and maize crop plots after the harvest in the summer autumn season of 2022. They were air dried and sieved at a 2 mm mesh, then were analyzed to physico-chemical characterization using standard laboratory techniques in 2023.
Our results indicate that soil properties were linked significantly to different cropping patterns including paddy soils and maize soils. Analysis of soil characteristics demonstrated that rice soils are finer textured (clay content = 30.1%), whereas maize soils have clay content lower than 25%. All 10 properties are significantly different for the rice field and another of which CEC and organic matter content are the most important to govern other characteristics. The content of organic matter was higher in fields with two rice crops (3.49%) than in fields with maize crops (2.20%).
