    Chad Sanders.
    Summary: "When Chad Sanders landed his first job in lily-white Silicon Valley, he quickly concluded that to be successful at work meant playing a certain social game. Each meeting was drenched in white slang and the privileged talk of international travel or folk concerts in San Francisco, which led Chad to believe he needed to emulate whiteness to be successful. So Chad changed. He changed his wardrobe, his behavior, his speech--everything that connected him with his Black identity. And while he finally felt included, he felt awful. So he decided to give up the charade. He reverted back to the methods he learned at the dinner table, or at the Black Baptist church where he'd been raised, or at the concrete basketball courts, barbershops, and summertime cookouts. And it paid off. Chad began to land more exciting projects. He earned the respect of his colleagues. Accounting for this turnaround, Chad believes, was something he calls Black Magic, namely resilience, creativity, and confidence forged in his experience navigating America as a Black man. Black Magic has emboldened his every step since, leading him to wonder: Was he alone in this discovery? Were there others who felt the same? In essays, Chad dives into his formative experiences to see if they might offer the possibility of discovering or honing this skill. He tests his theory by interviewing Black leaders across industries to get their take on Black Magic. Black Magic explores Black experiences in predominantly white environments and demonstrates the risks of self-betrayal and the value of being yourself"--adapted from dust jacket.

    The distribution of phosphorus capital and net annual transfers of phosphorus between the major components of two unfertilized phosphorus-deficient UK ecosystems, an oak--ash woodland in the Lake District and an Agrostis-Festuca grassland in Snowdonia (both on acid brown-earth soils), have been estimted in terms of kg P ha--1. In both ecosystems less than 3% of the phosphorus, totalling 1890 kg P ha--1 and 3040 kg P ha--1 for the woodland and grassland, respectively, is contained in the living biomass and half that is below ground level. Nearly all the phosphorus is in the soil matrix. Although the biomass phosphorus is mostly in the vegetation, the soil fauna and vegetation is slower (25%) than in the grassland vegetatation (208%). More than 85% of the net annual vegetation uptake of phosphorus from the soil is returned to the soil, mainly in organic debris, which in the grassland ecosystem is more than twice as rich in phosphorus (0.125% P) as in the woodland ecosystem (0.053% P). These concentrations are related to the rates of turnover (input/P content) of phosphorus in the litter layer on the soil surface; it is faster in the grassland (460%) than in the woodland (144%). In both cycles plant uptake of phosphorus largely depends on the release of phosphorus through decomposition of the organic matter returned to soil. In both the woodland and the grassland, the amount of cycling phosphorus is potentially reduced by its immobilization in tree and sheep production and in undecomposed organic matter accumulating in soil. It is assumed that the reductions are counterbalanced by the replenishment of cycling phosphorus by (i) some mineralization of organically bound phosphorus in the mineral soil, (ii) the income in rainfall and aerosols not being effectively lost in soil drainage waters and (iii) rock weathering. The effects of the growth of conifers and sheep grazing on the balance between decomposition and accumulation of organic matter returned to soil are considered in relation to the rate of phosphorus cycling and the pedogenetic changes in soil phosphorus condition leading to reduced fertility. Although controlled sheep grazing speeds up phosphorus cycling and may reverse the pedogenetic trend in favour of soil improvement, conifers may slow down phosphorus cycling and promote the pedogenetic trend towards infertility.
