Abstract

Various soil health indicators that measure a chemically defined fraction of nitrogen (N) or a process related to N cycling have been proposed to quantify the potential to supply N to crops, a key soil function. We evaluated five N indicators (total soil N, autoclavable citrate extractable N, water-extractable organic N, potentially miner-alizable N, and N -acetyl- β - D -glucosaminidase activity) at 124 sites with long-term experiments across North America evaluating a variety of managements. We found that 59%–81% of the variation in N indicators was among sites, with indicator values decreasing with temperature and increasing with precipitation and clay content. The N indicators increased from 6%–39% in response to decreasing tillage, cover cropping, retaining residue, and applying organic sources of nutrients. Overall, increasing the quantity of organic inputs, whether from increased residue retention, cover cropping, or rotations with higher biomass, resulted in higher values of the N indicators. Although N indicators responded to management in similar ways, the analysis cost and availability of testing laboratories is highly variable. Further, given the strong relationships of the N indicators with carbon (C) indicators, measuring soil organic C along with 24-h potential C mineralization could be used as a proxy

长期农业试验中土壤健康氮指标的评价

已经提出了各种土壤健康指标，用于测量化学定义的氮含量或与氮循环相关的过程，以量化向作物供应氮的潜力，这是一种关键的土壤功能。我们在124个地点评估了五个氮指标（土壤总氮、可高压灭菌的柠檬酸盐可提取氮、可水提取的有机氮、潜在的可矿化氮和N-乙酰基-β-D-氨基葡萄糖酶活性），并在北美进行了长期实验，评估了各种管理方法。我们发现，59%–81%的氮指标在不同地点之间变化，指标值随着温度的升高而降低，随着降水量和粘土含量的增加而增加。由于减少耕作、覆盖种植、保留残留物和施用有机营养源，氮指标从6%增加到39%。总的来说，增加有机投入的数量，无论是通过增加残留量、覆盖种植还是生物量更高的轮作，都会导致氮指标的值更高。尽管N个指标对管理层的反应类似，但分析成本和测试实验室的可用性变化很大。此外，考虑到氮指标与碳（C）指标之间的密切关系，测量土壤有机碳以及24小时潜在的碳矿化可以用作替代
