Whether a company goes with one or the other will largely depend on their goals, their capital, and their resources. Ecol. J.

An official website of the United States government. Higher root density in the E horizon of oak-pine uplands as compared to the other forest types was associated with high nutrient content; higher root density in the C horizon of pine-oak lowlands was associated with a shallow water table beneath the horizon; and lower root densities in the B and C horizons of pine-oak plains were associated with the presence of a firm clay layer in the B horizon. Root density correlated positively with organic C, total N, water soluble P, exchangeable Ca, Mg, K, Al, Fe, and cation exchange capacity, and negatively with bulk density, coarse fraction content, and pH, whereas root abundance correlated positively with organic C, total N, water soluble P, exchangeable Ca, Mg, K, and Fe, and negatively with bulk density.

We found that NPP in both aboveground (ANPP) and belowground (BNPP) increased nonlinearly as precipitation increased, while the allocation of NPP to BNPP (fBNPP ) showed a concave quadratic relationship with precipitation.

The idea that the roots of different species might segregate by depth is one of the oldest hypotheses for a mechanism that might explain plant species coexistence in diverse communities like grasslands (Parrish & Bazzaz, 1976).The logic is simple: if plant species distribute their root biomass differently with depth, this .
