Long-term maize-soybean crop rotation: impacts on soybean yield, soil microbiota and nitrogen dynamics.

ABSTRACT:

Aims

Soil nitrogen is recognized as a vital nutrient influencing soybean growth and yield. Hence, a comprehensive understanding of the intricate connections between shifts in nitrogen patterns and the behaviors of soil microbial communities and crucial enzymes in the nitrogen cycle is highly desirable.

Methods

This study involved a rotation positioning experiment spanning 11 years (2012-2022). Measurement of soil microenvironment changes during the mature period for three consecutive years (2020-2022). Based on these groups, the study delved into the alterations in nitrogen patterns within the soybean rotation, examining both soil enzyme activity and microbial community dynamics.

Results

Long-term crop rotation and nitrogen application led to an increase ranging from
