Public Notice: DOGAMI Rule Writing for Aggregate

2020-3-30 · DOGAMI Rule Writing for Aggregate Mining on High Value Farm Soils . What: DOGAMI has started the process of writing a new rule for aggregate mining on high value farm soils. This rule stems from the passage of House Bill 2202 (HB 2202) in the 2013 legislative session and resulted in ORS 517.825 which became effective on August 1, 2013.

Soil Aggregate an overview ScienceDirect Topics

A mechanism particularly prevalent in many tropical soils is the physical aggregation process, which occurs abiotically as a physicochemical process (Oades and Waters, 1991). In both temperate and tropical soils, there are several biological processes that result in the formation of “biological macroaggregates” (Fig. 3.12, Six et al., 2002b). These include the following: (1) fresh plant- and root

2018-10-1 · Human activities, such as industrial processing, mining, fossil fuel combustion, and industrial processing can release large amounts of heavy metals into the surface soils (Wang et al., 2014). Previous studies have indicated that heavy metal concentrations in soils are strongly influenced by soil aggregate-size distribution ( Huang et al., 2017 ; Xiao et al., 2016 ).

Effects of surface coal mining and land reclamation on

2019-4-1 · Silty soils and soils with high clay content are more easily compacted and restrict soil aeration and drainage, which are chief causes of poor tree survival and growth (Jones et al., 2005). Moreover, large machinery compaction causes soil aggregation changes, which may decrease water and nutrient availability, aeration and plant production due to limitation in root growth ( Abu-Hamdeh, 2003 ; Kim et
