REGIONAL ASSESSMENT OF SOIL NITROGEN MINERALIZATION IN DIVERSE CROPLAND OF A REPRESENTATIVE INTENSIVE

Frontiers of Agricultural Science and Engineering 2023, Volume 10, Issue 4,   Pages 530-540 doi: 10.15302/J-FASE-2023515

Abstract:

Soil nitrogen mineralization (Nmin) is a key process that converts organic N into mineral N that controls soil N availability to plants. However, regional assessments of soil Nmin in cropland and its affecting factors are lacking, especially in relation to variation in elevation. In this study, a 4-week incubation experiment was implemented to measure net soil Nmin rate, gross nitrification (Nit) rate and corresponding soil abiotic properties in five field soils (A–C, maize; D, flue-cured tobacco; and E, vegetables; with elevation decreasing from A to E) from different altitudes in a typical intensive agricultural area in Dali City, Yunnan Province, China. The results showed that soil Nmin rate ranged from 0.10 to 0.17 mg·kg−1·d−1 N, with the highest value observed in field E, followed by fields D, C, B, and A, which indicated that soil Nmin and Nit rates varied between fields, decreasing with elevation. The soil Nit rate ranged from 434.2 to 827.1 µg·kg−1·h−1 N, with the highest value determined in field D, followed by those in fields E, C, B, and A. The rates of soil Nmin and Nit were positively correlated with several key soil parameters, including total soil N, dissolved organic carbon and dissolved inorganic N across all fields, which indicated that soil variables regulated soil Nmin and Nit in cropland fields. In addition, a strong positive relationship was observed between soil Nmin and Nit. These findings provide a greater understanding of the response of soil Nmin among cropland fields related to spatial variation. It is suggested that the soil Nmin from cropland should be considered in the evaluation of the N transformations at the regional scale.

Keywords： cropland     gross nitrification rate     regulatory factors     soil nitrogen mineralization     spatial variation

Frontiers of Structural and Civil Engineering 2011, Volume 5, Issue 3,   Pages 323-334 doi: 10.1007/s11709-011-0119-5

Abstract: When a PT frame deforms laterally, gaps between the beams and columns open.However, the gaps are constrained by the columns and the slab in a real PT self-centering building frameThe method is verified by cyclic tests of a full-scale, two-bay by one-story PT frame.Moreover, a sliding slab is proposed to minimize restraints on the expansion of the PT frame.only minor differences in peak drifts caused by expansion of the PT frame.
