一个简单的模型有可能解决海洋学家之间长期存在的关于氮或磷是否对海洋初级生产力产生全面控制的争论。固氮和其他浮游植物之间的竞争的代表插入到一个两个盒子的海洋氮和磷循环的全球模型。稳态调节硝酸盐和磷酸盐浓度的结果，与表面沃茨更缺乏硝酸盐比磷酸盐在稳定状态下，但与外部磷酸盐输入控制长期初级生产在全球海洋。
A simple model has the potential to resolve the long-running debate amongst oceanographers over whether nitrogen or phosphorus exerts overall control on oceanic primary production. A representation of the competition between nitrogen-fixing and other phytoplankton is inserted into a two-box global model of the oceanic nitrogen and phosphorus cycles. Homeostatic regulation of both nitrate and phosphate concentrations results, with surface waters more deficient in nitrate than phosphate in the steady state, but with external phosphate inputs controlling longer-term primary production in the global ocean.
