The object of this research is the mining relations in Sunda Islands Malay Archipelago. Analysis conducted on normative legal regulation subsoil use Republic Indonesia, regime which uniform for zones located island and offshore territories within Indonesian jurisdiction, but differentiated depending type mineral resources. author meticulously examines state mechanism management industry, placin...
The inability of crop roots to penetrate subsoil layers in some Natal sandy soils and the associated low yields are the result of toxic quantities of aluminium. The phenomenon which is common in acid sandy soils in Naltal may be easily remedied by deep liming or leaching with gypsum.
W hat constitutes “long-term” research may be as apparent as collectable art; although many are quick to identify the plots in Rothamsted-UK, started in 1843, as the gold standard of long-term research. When researchers conduct experiments in reference to a hypothesis that determines treatment application, the test duration usually lapses after a few “climatically representative” years. Mr. O. ...
A soil profile contaminated as a result of Zn smelting operations from the historic Palmerton, PA smelting facility was characterized using X-ray absorption fine structure spectroscopy (XAFS) and X-ray diffraction (XRD) as bulk techniques, coupled with electron microprobe (EM), and microfocused XAFS as microscopic techniques to determine the chemical forms of Zn and elucidate its geochemical fa...
In sandy soils of the southeastern USA coastal plains, crop production is limited by low water holding capacity and compacted soil layers that reduce root growth and productivity. Polyacrylamide (PAM) was added to sandy coastal plain soils to improve physical properties and yield. Soils were amended with linear and cross-linked PAMs. Treatments and controls included the following: (1) spraying ...
Zinc speciation in a smelter-contaminated soil profile using bulk and microspectroscopic techniques.
