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.

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-

Publisher Summary The genesis of Vertisols is strongly influenced by soil movement (contraction and expansion of the soil mass) and the churning (turbation) of the soil materials. These soils have the capacity to swell and shrink, inducing cracks in the upper parts of the soil and distinctive soil structure throughout the soil. The formation of these

The fate of phosphorus during pedogenesis
Geoderma, 1976Abstract The fate of phosphorus (P) during pedogenesis is considered with particular emphasis on vertical distribution within the profile. Information is based on P fractionation studies involving a range of soil sequences in New Zealand. Forms of P in soil parent materials are discussed in relation to soil P transformations.

Quantifying Pedogenesis for Soils with Discontinuities
Soil Science Society of America Journal, 1973Abstract Comparing calculated values of changes with observable features in relatively young soils is one way of testing genetic assumptions. If the agreement is acceptable, then the probability that the assumptions are correct increases.

Conceptual Approaches to Pedogenesis
2004To fully appreciate and apply pedologic principals in archaeology, some of the theoretical underpinnings of pedology and especially soil geomorphology must be outlined. Pedologists and soil geomorphologists have attempted to describe, if not model, the processes of soil formation, the factors that drive the processes, and the evolution of soils as ...

Andosols in Germany—pedogenesis and properties
CATENA, 2004Abstract Soils conforming to Andosols in the World Reference Base (WRB) of Soil Resources have not yet been recognised in Germany. The aims of this study were to (i) show whether some German soils developed in volcanic parent materials are Andosols, (ii) investigate their pedogenetic development and (iii) determine their local distribution.

Electrical parameters of soils and pedogenesis
Eurasian Soil Science, 2008A concept of the relationship between the electrical parameters of soils (the electrical resistivity and the natural electrical potential) and their pedogenesis was advanced on the basis of the known classical laws of electromagnetism and the general theory of pedogenesis.
