Interpretive Summary:

Technical Abstract: Boron is an essential micronutrient element required for plant growth. Boron deficiency is wide-spread in crop plants throughout the world especially in coarse-textured soils in humid areas. Boron toxicity can also occur, especially in arid regions under irrigation. Plants respond directly to the B concentration in soil solution and only indirectly to the amount of B attached to soil surfaces. Therefore, the soil adsorption complex acts as both a source and a sink for dissolved B and can mitigate phytotoxic soil solution B concentrations. Plant B response is affected by many aspects of B soil chemistry. In this review we will treat several of these topics: i) methodologies for determining the mechanisms of B attachment to soil particle surfaces; ii) kinetics of B adsorption reactions; iii) description and prediction of B adsorption reactions using chemical models; iv) use of B soil tests to predict plant response in field situations.
