“…The stocks and relative proportions of these different forms of P change during pedogenesis, with a decrease of calcium phosphates and a build-up of organic P, non-occluded P i (P i on surfaces) and occluded P i (P i within secondary minerals) over time (Walker and Syers, 1976). When revisiting one of the soil chronosequences studied by Walker and Syers, Turner et al (2013) found that microbial biomass P represented up to 40% of total organic P. Soil microorganisms contain inorganic as well as organic P (Bünemann et al, 2011). By (operational) definition, however, they are often included in the total organic P of the soil.…”

“…In order to properly identify plant fertilisation needs, the current supply of certain macroelements to the fertilised soils has to be known. These include such elements as phosphorus (Berg and Joern, 2006;Bünemann et al, 2011;Fernandes et al, 2000;Mc Dowell and Sharpley, 2003), potassium (Brennan and Bell, 2013;Fotyma, 2007;Moody and Bell, 2006), magnesium (Tkaczyk et al, 2016;Tyler and Olsson, 2001) and sulphate-sulphur (Gąsior and Alvarez, 2012;Szulc et al, 2014), and microelements such as boron (Majidi et al, 2010;Shaaban, 2010;Szulc and Rutkowska, 2013), copper Su and Yang, 2008), iron (Mcgrath and Zhao, 2006), manganese (Antonkiewicz et al, 2016) and zinc (Barczak et al, 2009;Domańska, 2009;Rutkowska et al, 2014a). This knowledge should be complemented by the equally important data on other physicochemical properties of the fertilised soils, such as pH KCl or humus content (Aponte et al, 2010;Lipiński and Bednarek, 1998).…”

In the years 2008-2011, an environmental study was conducted for Polish soils, focusing on the south-eastern Poland soils, as they exhibit significant acidification. This study aimed at assessing the current pHKCl and the supply of basic macro- (P, K, Mg and S-SO4) and microelements (B, Cu, Fe, Mn and Zn) in the collected soil samples, and also at determining their relationship with the soil agronomic category, humus content and pH class. Soil reaction and humus and macronutrient content were positively correlated with the amount of colloidal clay and particles < 0.02 mm. In the majority of cases, the macro-element content in the soil was positively correlated with soil pH and humus content. As for microelements, a usually significant and positive correlation was found between the soil agronomic category and the content of manganese, iron and zinc, whereas for the content of boron and copper, no such relationship was observed. A significant and positive correlation between soil reaction and the content of manganese, iron and boron was also found. Such correlations were not observed in relation to copper and zinc content. Statistical analysis indicated that the content of boron and manganese depended to the greatest extent on the investigated physicochemical properties.

“…The PS actinomycetes, however, through the release of organic acid (acidification) (Hoberg et al 2005;Abdulla 2009) and by other mechanisms such as chelation, exchange reactions, and polymeric substances formation (Delvasto et al 2006) convert the insoluble forms of P into soluble forms. The organic anions assist P solubilization mainly in two ways: (a) lowering pH and (b) ligand exchange reaction (Beunemann et al 2011;Balemi and Negisho 2012). However, the organic anions in some cases have been found not to acidify the medium, probably because once they are released in soil, they already exist in the dissociated form due to their low acid dissociation constants (pKa).…”

Phosphorus (P), an essential plant nutrient, is a nonrenewable resource whose availability depends exclusively on mined rock phosphates. Deficiency of P in soil results in reduction in food production since all plants require an adequate supply of P for its growth and development. Even though synthetic phosphatic fertilizer has played some major roles in enhancing crop production, its excessive use has also dark sides to it where it has been found to damage the environment, destruct soil fertility, and, via food chain, seriously affect the human health. Considering the nuisance of overuse of P, there is an urgent demand by the agriculture practitioners to find nonhazardous strategy that can overcome/reduce the use of agrochemicals in agricultural practices and, hence, may preserve the very integrity of soil ecosystems. In this context, actinobacteria, a group of Grampositive bacteria, ubiquitous in soils, are likely to play some important roles in supplying soluble P to plants by solubilizing/mineralizing complex P resources of soils. Additionally, the extracellular metabolites produced by actinomycetes may inhibit phytopathogens and, sometimes such metabolic compounds may also act as plant growth regulators. These qualities, among others, make actinobacteria an ideal candidate for developing as microbial inoculants for ultimate use in agriculture production system. The potential roles of actinomycetes as phosphate solubilizers in enhancing crop production are discussed.
