Abstract Black (pyrogenic) carbon (BC) has its origin in incomplete combustion of organic matter. It is considered to be a stable fraction of soil organic carbon (SOC) accounting for a great proportion of SOC in many soils. The aim of this article is

The aim of the paper is to give an overview on the chemistry of soil organic carbon (SOC) affecting nutrient availability, the emission of greenhouse gases and detoxifying harmful substances in soil. Humic substances represent the stable part of SOC,

The organic carbon content of soils is a key parameter of soil fertility. Moreover, carbon accumulation in soils may mitigate the increase in atmospheric CO2 concentration. The principles of carbon accumulation in arable soils are well known. The inc

Phosphate (P) fixation to the soil solid phase is considered to be important for P availability and is often attributed to the strong binding of orthophosphate anion species. However, the fixation and subsequent immobilization of inositolhexa and pen

In the last three decades, the concept of soil humic substances has been questioned in two main directions. Misinterpretations of CP MAS13C NMR spectroscopy led to the conclusion that soil organic matter is mainly aliphatic, questioning the theory of

Humic substances affect iron (Fe) and phosphate (P) uptake by higher plants by two different ways. First, humic substances bind Fe(III) by forming humic‐Fe complexes of medium to high stability. In soils with pH > 5.0 these complexes account for mo

Phosphorus is one of the most limiting macronutrients for plant productivity in agriculture worldwide. The main reasons are the limited rock phosphate reserves and the high affinity of phosphate (P) to the soil solid phase, restricting the P availabi

The chemical interaction between soil organic matter and the orthophosphate anion (phosphate [P]) is important for reactions of P at the soil solid phase, in soil solution, and in natural waters. Humic substances account for an important or dominant
