Different nitrogen uptake patterns of plant and soil microorganisms in the forest-grassland transition zone on the Loess Plateau.

ABSTRACT:

Introduction

It is unclear whether plants and microorganisms achieve niche complementarity by taking up different inorganic nitrogen (N) forms to alleviate N competition, particularly in N-limited regions.

Methods

This paper conducted a 15-day ¹⁵N tracer study (¹⁵NH₄NO₃ or ¹⁵NH₄NO₃) in situ to quantitatively calculate the uptake rates of plants and microorganisms in four stands (pure Hippophae rhamnoides L, pure Pinus tabuliformis Carrière, mixed H. rhamnoides-P. tabuliformis, and Artemisia gmelinii Weber ex Stechm grassland) in the forest-grassland transition zone on the Loess Plateau during the growing season. Among them, H. rhamnoides and P. tab
