TL;DR: In this article, the impact of pyrolysis temperature on two important soil hydrologic properties, namely field capacity and hydrophobicity, was investigated. And they found that both properties can be controlled by choice of pyrotechnic temperature, and that 400°C-600°C produced biochars with the most desirable hydrological properties.

TL;DR: The addition of biochar can increase or decrease soil drainage, and suggests that any potential improvement of water delivery to plants is dependent on soil type, biochar amendment rate, and biochar properties.

TL;DR: The lateral distribution of topsoil by erosion controls the availability, stock, and persistence of essential elements in the t... as mentioned in this paper. But, most of Earth's terrestrial surface is made up of sloping landscapes.

TL;DR: In this paper, a global radiocarbon data set suggests that human disturbance is also introducing aged carbon to rivers and to active carbon cycling and that most dissolved organic carbon in rivers originates from young carbon in soils and vegetation.

TL;DR: 12 hypotheses that must be tested to improve understanding of the Critical Zone are advanced, showing how biogeochemical properties impart thresholds or tipping points beyond which rapid and irreversible losses of ecosystem health, function, and services can occur.
