Soil Science, 1988
The analysis of soil solutions generated by a large, isolated, summer rainstorm in the boreal forest of arctic Alaska has provided direct evidence for threshold-controlled subsurface translocation in soils. Intense leaching apparently initiates progressive weakening and eventual break-down of amorphous particle coatings in the Bs horizon. The result is

The role of earthworms as one of the most important groups of ecosystem engineers in human-modified and natural environments has been increasingly recognized only during the last 30 years, yet earthworms and humans have been acting together in building landscapes for millennia.

Rates of Pedogenesis in Reclaimed Lands as Compared to Rates of Natural Pedogenesis
Soil Horizons, 2014Reclamation is performed on disturbed lands to return the land to productivity as rapidly as possible. From the perspective of the pedologist, the ultimate in reclamation would be to return the soil resource to its previous condition as rapidly as possible, but do reclamation methods increase rates of pedogenesis?

Proceedings of the International Conference on Mine Closure, 2006
Although mine tailings dams are man-made deposits it is anticipated that soil forming (pedogenic) processes are active e.g. translocation and transformation. These two main groups of soil forming processes are controlled by environmental factors, also called soil forming factors; parent material, climate, topography, and biota. In the case of man

EVOLUTION MODEL OF PEDOGENESIS
Soil Science, 1987This comprehensive model of soil genesis is based on the observation that soils (S) evolve along two coacting pathways: progressive (P) and regressive (R). For all soils S=f(P, R). The progressive pathway includes conditions, processes, and factors that promote horizonation, developmental ...

Soil Complexity and Pedogenesis
Soil Science, 2017ABSTRACTThis paper reviews recent developments in studies of soil complexity, focusing on the variability of soil types within soil landscapes. Changes in soil complexity are directly related to divergent and convergent pedogenesis and to dynamical stability and chaos.

PHOSPHORUS DYNAMICS DURING PEDOGENESIS ON SERPENTINITE
Soil Science, 1999Many studies on the dynamics of P deal with soils in which calcium and pedogenic iron oxides are the most important factors controlling P fate, whereas serpentinitic soils are characterized by the presence of lithogenic iron oxides and low amounts of calcium in the soil solution.

Role of Bacteria in Pedogenesis
2019Most commonly microorganisms are known as disease causing agents amongst common people but when we turn towards their positive aspects they do wonderful things. Microbes have remained an integral part of soil since ever earth originated. They are capable of turning soil into waste land and further into productive soil.

Quantitative models for pedogenesis — A review
Geoderma, 2008Abstract Pedogenesis models should give us answers to: how does soil form, how does it evolve, where does it come from and how long does it take to reach this state? This paper reviews quantitative models that describe pedogenesis ab initio and the processes that directly lead to development or evolution of soil. We review factorial, energy, and mass-
