Soil Properties Influence Distribution of Extractable Boron in Soil Profile

Studies on Boron Fractions with Different Physico-Chemical Properties of Cultivated Soils of Himachal Pradesh, India

“…Similar findings have been stated by various other researchers (Datta et al, 2002 andSarkar et al, 2008). The greatest significant correlation was observed between residual boron and total boron (r = 0.99**) followed by relationship between readily soluble and specifically adsorbed boron (r = 0.98**).…”

“…Recent estimates suggested B deficiency in one-third of over 40 thousand soil samples analysed (Shukla et al, 2012). Most of the research on soil B in India remained confined to the determination of hot water soluble B (Moafpouryan and Shukla, 2002;Sarkar et al, 2008), with only sporadic attempts of B fractionation (Datta et al, 2002;Chaudhary and Shukla, 2004).…”

Depth Wise Distribution of Boron in Some Soils of Red and Laterite Zone of West Bengal, India

“…Sarkar et al, (2008) also found significant and positive correlation with soil pH. As the soil is highly weathered soil, rich in iron and aluminium oxide, large portion of B is bound with these oxides.…”

“…This decrease may be due to decreasing organic carbon content, clay content and Fe content with depth (Table 1). Sarkar et al, (2008) Table.2 Depth wise distribution of B in red and lateritic soils Table. …”

Liming Effects on Extractable Boron in Six Acidic Soils

“…Of the two soil groups, Inceptisols (Matikata, Sonarpur, and Itahar) contained a greater amount than Alfisols (Purulia, Hura, and Bankura), the mean values being 0.15 and 0.10 mg kg −1 , respectively (Figure 1). Inherently low B content due to its fixation by greater amount of Fe-and Al-oxides present in Alfisols and leaching from light-textured acidic Inceptisols receiving high precipitation have been researched for the observed deficiency of B in these two soil groups (Mandal, Ghosh, and Chattopadhyay 2004;Sarkar et al 2008). Liming, on average, increased availability of native soil B initially (at the fifteenth day) and then decreased progressively with time ( Figure 1).…”
