Group members are also in favour of adopting more stringent limits regarding impurities in feed phosphates used in all types of feed material. Eventually guano also failed to be a sustainable source of phosphorus fertilizer. Instead, most of the phosphorus that’s used for human food production comes from rock phosphate. Similarly, the formulation of typical plant-based diets for monogastrics demonstrates that it is impossible to meet the animals’ phosphorus requirements with these materials alone. These are substantial challenges that will require all of us, food producers and food consumers, to work together. What are sources of phosphorus for crops?

In order to fully reflect the source of the phosphorus in Daya Bay, rainwater samples for δ 18 O P analysis were simultaneously collected at the Marine Biology and Resources Station (MBRS), Aotou station (AT), and Xunliao station (XL) from October 2015 to March 2017, and then, they were mixed to trace the sources of phosphorus considering the proximity of these three sites (less than 20 km). The oxygen isotope ratio of phosphate (δ 18 O PO 4) can shed light on P sources and P cycling in ecosystems. The following list provides a description of the different sources for phosphorus along with a brief description of how each source is managed and what can be done to minimize over use. People should avoid eating meats which typically contain more easily absorbed phosphorus than found in plants.

Phosphorus is naturally present in the earth and it is also added to the environment through other sources including fertilizers, detergents, and human and animal feces. Main phosphate sources are of plant, animal and inorganic origin, containing varying quantities of phosphorus in several different chemical forms.
