A review of the phosphorus content of dry cereal and legume crops of the world
When food scarcity increases, instability in society increases. The majority of food consumed is from cereals and legumes. Phosphorus is essential for crop plant growth and soils are depleted as this element is removed from crop lands with harvested grains/seeds. To sustain yields, inputs of nutrients are required to balance losses. On global and continental/regional bases, we assembled nine ...
