Soil plays a key role in all food production, with soils providing over 95% of food and mineral nutrition for human life [<\/span>1]<\/span>. My PhD research is focused on the role of soils and nutrients in soybean, with a focus on phosphorus (P). Soybean (<\/span>Glycine max<\/span><\/i> L. (Merr.)) is a globally important crop, with production levels today being 13 times higher than the 1960s [<\/span>2]<\/span>. Soybean, or soya as it is more commonly known, acts as the largest source of both vegetable oil and animal feed, as well as being a key component of vegan or vegetarian diets [<\/span>3]<\/span>. The demand for soya is continuing to increase, with 5% of the UK population now being vegan or vegetarian [<\/span>4]<\/span> contributing to demands of increased soybean production.\u00a0<\/span>\u00a0<\/span><\/p>\n

<\/p>\n

There are two basic ways to meet this demand, expanding production area, or improving production levels in current production areas. We are suggesting that the more sustainable option is to do this by improving production levels and closing yield gaps. Closing yield gaps, i.e. growing more crop per unit area, has the potential to meet this demand. We are suggesting that one such way to close these yield gaps is through improved P fertiliser application, however, we are unsure if the benefits outweigh the costs. Hence the question, To P or not To P? Phosphorus fertiliser application has high environmental costs \u2013 costs of production and transport, and it\u2019s environmental damage to waterbodies.\u00a0 <\/span>\u00a0<\/span><\/p>\n

Phosphorus not only plays a key role in crop production, but also in human health. Phosphorus is a major component of bones, teeth, DNA and RNA, as well as being a component of cell membrane structure and the body\u2019s key energy source ATP, soybeans and fermented soy provide up to 100% of the recommended daily intake [<\/span>5]<\/span>. However, it is not as simple as applying more P fertiliser to soybean cropping systems to provide more soy, there are several pathways and mechanisms that we hope to understand more throughout my PhD. <\/span>\u00a0<\/span><\/p>\n
