Impacts of Microplastics on the Soil Biophysical Environment

Microplastics represent potential threat for soil biota if contamination would cause changes on the soil habitat. Empirical calculations suggest that about 32% of all plastic produced is environmentally available in continental systems, and certain authors argue that soils might store more microplastic litter than oceanic basins.

Soil water salinity can affect soil physical properties by causing fine particles to bind together into aggregates. This process is known as flocculation and is beneficial in terms of soil aeration, root penetration, and root growth.

Influence of Plant Root Systems on Subsurface Flow

From a strictly mechanical point of view, the orientation in which roots are aligned with regard to slope direction can affect soil reinforcement, depending on whether the plant is located at the top or at the bottom of a slope (Genet et al. 2010, Thomas and Pollen-Bankead 2010). From a hydrological perspective, root orientation is also important.

AP Notes - Soil

Soil pH is important because it affects the solubility of nutrients; and thus in turn determines the extent to which these nutrients are available for absorption by plant roots. If the soil is too basic or too acidic, certain soil nutrients will not be able to be used by regional plants. WHERE DOES SOIL COME FROM?

How does tillage intensity affect soil organic carbon? A

The loss of carbon (C) from agricultural soils has been, in part, attributed to tillage, a common practice providing a number of benefits to farmers. The promotion of less intensive tillage practices and no tillage (NT) (the absence of mechanical soil disturbance) aims to mitigate negative impacts on soil quality and to preserve soil organic carbon (SOC). Several reviews and meta-analyses have ...
