PHOSPHORUS IN THE ENVIRONMENT: Natural Flows and Human Interferences. Phosphorus has a number of indispensable biochemical roles, but it does not have a rapid global cycle akin to the circulations of C or N. Natural mobilizat... Smil,Vaclav - 《Annual Review of Energy & the Environment》 被...
Eight years later, they have only just started to observe the first signs of phosphorus shortage. (英国作物科学家Roger Sylvester-Bradley迈出了合乎常理的第一步:他们停止向一半的大麦田添加磷肥,以观察植物的生长情况。八年后,他们才刚刚开始观察到磷短缺的最初迹象)”以及“Our production isn’t changing...
1993). Despite its importance to the total marine sedimentary phosphorus inventory, advances in understanding the compositional makeup of sedimentary organic phosphorus have been fairly limited, due in large part to the analytical difficulties associated with characterizing its molecular forms. The principle...

We determined bioavailable, dissolved organic phosphorus (BAP) by measuring changes in dissolved organic phosphorus (DOP) in experiments using 0.8 μm filtered seawater, representing the free bacteria fraction, with the addition of carbon and nitrogen. Experiments were conducted at 3 stations in the ...

Take chemical fertilizers, which deliver nitrogen, an essential plant nutrient, to crops along with some phosphorus and potassium. It is a mantra of organic farming that these fertilizers are unwholesome, and plant nutrients must come from natural sources. But in fact, the main ...
