Abstract
Boron (B) is an important plant micronutrient with a narrower range of deficit to toxicity than any other plant nutrients. As a result, comprehending the chemistry of born in soil is crucial. Although B inadequacy and toxicity may be linked to total B levels in the soil, these issues are caused by the chemical forms of B present in the soil, notably its solubility and availability to plants. Solution pH, soil texture, soil moisture, temperature, organic matter, and clay mineralogy all impact B availability and its adsorption in soils. Various empirical equations may be used to characterize boron adsorption processes. Due to the latest fertilizer technologies which provide better nutrient dissemination, year-round B availability, and a more adjustable application window in diverse crops boron management has improved dramatically. This paper reviews about different studies and progress of research in dynamics of boron and its management in different horticulture and agriculture crops.
Keywords: Boron, boron chemistry, adsorption-desorption of B, management of B
