Sentences with phrase «deeper soil horizons»

Not exact matches

A team led by scientists at Lawrence Berkeley National Laboratory found that the type of plant inputs (that is, root or needle litter) affected total carbon and nitrogen retention over 10 years, but that soil horizon (essentially, the layer of soil, such as the topsoil organic or deeper mineral layers) affected how the litter - derived soil organic material is stabilized in the long term.

«Conversely, the preferential cultivation of soils with higher clay, lower sand, and stone contents (Fig. 2) could mean that soils used for cultivation have inherently higher productivity or greater capacity for C storage below 10 cm (e.g., through illuviation with clay minerals), and that these fundamental differences in soil properties are responsible for patterns of C storage in deeper horizons.
