Summary

This 2025 field study examined how agricultural cultivation duration shapes soil inorganic nitrogen cycling and supply capacity in subtropical karst agroecosystems. By sampling sites with contrasting land-use histories, the authors quantified nitrogen turnover dynamics to elucidate how cumulative cultivation history alters soil nitrogen availability. The findings contribute to understanding nutrient management constraints in karst farming systems, where inherently limiting baseline soil conditions restrict agricultural productivity.

UK applicability

Karst soils are not prevalent in the UK, limiting direct applicability of region-specific findings. However, the study's framework for assessing how cultivation duration affects nitrogen cycling may inform understanding of long-term soil fertility changes under different land-use histories in contrasting UK soil types.

Key measures

Soil inorganic nitrogen turnover rates, nitrogen supply capacity, net nitrification, net ammonification, and related soil biogeochemical parameters across sites differing in cultivation duration

Outcomes reported

The study quantified soil inorganic nitrogen turnover dynamics and supply capacity across sites with contrasting cultivation histories in subtropical karst agroecosystems. The research measured how cumulative cultivation duration alters soil nitrogen availability and cycling processes.
