Soil organic matter (SOM) is essential for sustaining food production and maintaining ecosystem services and is a vital resource base for storing C and N. The impact of long-term use of synthetic fertilizer N on SOM, however, has been questioned recently. Here we tested the hypothesis that long-term application of N results in a decrease in SOM. We used data from 135 studies of 114 long-term experiments located at 100 sites throughout the world over time scales of decades under a range of land…

These findings implicate fertilizer N in promoting the decomposition of crop residues and soil organic matter and are consistent with data from numerous cropping experiments involving synthetic N fertilization in the USA Corn Belt and elsewhere, although not with the interpretation usually provided.

A major global evaluation of current cereal production systems should be undertaken, with a view toward using scientific and technological advances to increase input efficiencies, and the input of ammoniacal N should be more accurately matched to crop N requirement.

Comparison of the N-concentration results with an estimate of the initial N concentration suggests that all fallow-containing monoculture wheat rotations and unfertilized Cont W have failed to maintain soil N, the unfertilsized 3-yr legume green manure-wheat-Wheat system has maintained soilN, while the 6-yr fallowing-cereal-hay (grass-legume) and fertilizedcont W systems have increased soil N.

This work shows that nitrogen additions significantly accelerate decomposition of light soil carbon fractions (with decadal turnover times) while further stabilizing soil carbon compounds in heavier, mineral-associated fractions ( with multidecadal to century lifetimes).
