The potential buffering capacity of soils in relation to the elements of plant nutrition.
In the general form, the provision of plants is assessed by two indicators: 1) The potential of chemical element (nutrient potential)—an energy characteristic, defined as the change in the Gibbs energy of the reaction 2) The potential buffering capacity of soils in relation to the elements of plant nutrition.
Further refinements were introduced to C-Fix, namely integration of a water limitation; temperature buffering and estimates of soil temperature [14].

The concentration of cadmium, arsenic and lead in soil, and their impact on body burden and excretion, is known to be influenced by many environmental factors such as the pH of soil, buffering capacity, content of organic matter and water quality, among others [ 50- 52].
In this study, the process performance and methane yield from SS-AD of alkaline-pretreated poplar processing residues (PPRs) were investigated using the properties of soil, such as buffering capacity and nutritional requirements.
However, few studies simultaneously investigated both intensities and frequencies of PyOM addition on soil chemical properties of soil base cations, soil pH buffering capacity (pHBC), and plant available micronutrients.
In contrast, MPK application had positive effects on the alleviation of soil acidification due to the buffering function of carbonates, bicarbonates, carboxyl and phenolic hydroxyl groups (Whalen et al. 2000; Garcia-Gil et al. 2004).
Organic matter may provide nearly all of the CEC and pH buffering in soils low in clay or containing clays with low CEC.
Working with MSS of the city of Larissa, central Greece by using representative acid and alkaline soils and wheat plants, it was found that MSS significantly increase the pH of acidic soils and decrease the pH of alkaline soils, showing a buffering effect on soil pH.
Further research is needed to identify the individual species of soil P that are involved in buffering the soil solution, and what their potential availability is to plants via rhizosphere modification.
