Disentangling management factors influencing nitrogen ...

2021-10-1  RESULTS AND CONCLUSIONS. Analysis based on combination of advanced statistics showed that soil organic matter (SOM), seeding rate, sowing date, and in-season N sidedress influenced N balance, mostly via N inputs application and, to a lesser degree, grain yield. In many cases, producer risk behavior explained the relationship between N balance and soil and management factors.

Global analysis of nitrogen and phosphorus limitation of ...

2007-10-8  The cycles of the key nutrient elements nitrogen (N) and phosphorus (P) have been massively altered by anthropogenic activities. Thus, it is essential to understand how photosynthetic production across diverse ecosystems is, or is not, limited by N and P. Via a large-scale meta-analysis of experimental enrichments, we show that P limitation is equally strong across these major habitats and ...

Does the nutrient stoichiometry of primary producers ...

2009-7-8  Consumers habitually face the problem of nutritional imbalances, as the nutrient content of their prey does not always meet their requirements, leading to a mismatch between supply and demand (Sterner and Elser 2002).Specifically, in the relationship between primary producers and herbivores, nutrients such as nitrogen (N) and phosphorus (P) are often limiting, as there is a surplus of carbon ...
