Diagram the relationship of phosphorus inputs and soil processes. List and describe inherent factors that affect soil phosphorus. The . texture. of a soil depends upon the proportion of sand, silt, and clay that are in the soil. The texture and soil structure (how the soil particles are arranged), influence the amount of pore spaces (or air) found within the soil. Pores are important conveyors of water, nutrients, and air, as well as provide space for roots to grow..
