Soil amendments showed contradictory results in heavy metal immobilization. Peat moss increased mobility and bioavailability of heavy metals in soil while peat moss-derived biochar decreased both through the coordination of metal electrons to CC bonds of the biochar.

Soil plays a vital role in supporting the growth of crops and other vegetation, maintaining the environment, and acting as source and sink for atmospheric gases. Soils are natural bodies on which plants grow. The increasing population, industrialization, and changing lifestyle have negative effect on soil and are responsible for soil pollution. Good soil and climate for more crop production are valuable things for any nation. Soil amendments can be used to cost-effectively reduce the bio-availability and mobility of toxic metals in contaminated soils. Organic amendments considerably affect nutrient balance and interaction mobility of nutrients by influencing the chemical, physical, and biological environment in soils. Here in this chapter, the author has discussed the soil, its profile and type, analysis, and benefits on rock phosphate amendments.

The aim of this study was to evaluate metals (Cd, Cu, Pb and Zn) sorption behavior after biochar application into a metal-contaminated soil. Additionally, two different types of biochar originated from the same organic material (contaminated and uncontaminated) at different application rates (1% and 2% w/w) were evaluated as a novelty of the experiment. Batch sorption/desorption experiments were established to compare the sorption behavior of metals originating from single- and multi-element solutions. Zinc as one of the main contaminants in the studied soil was easily desorbed in the presence of Cu, Pb and to a lesser extent by Cd. This desorption was reduced after biochar application. The obtained results proved the different sorption behavior of metals in the single-metal solution compared to the multi-metal ones due to competition effect. Moreover, during multi-element sorption, Zn was significantly desorbed. The applied biochar enhanced Cu and Pb sorption and no changes were observed when contaminated and uncontaminated biochar was used. Furthermore, the application rate (1% and 2% w/w) had no effect as well. In summary, it is needed to point out that the applied rates of biochars were insufficient for metal immobilization in such contaminated soils.
