Effect of boron fertilization on soil chemical properties, nutrients status in the soil and yield of crops under cauliflower-cowpea okra sequence in North East India

Liming and micronutrient application improves soil properties and productivity of the groundnut‐rapeseed cropping system in an acidic Inceptisol of India's eastern Himalayas

“…Residual effect of lime also accelerated the dissolution of calcium carbonate and other insoluble forms of Ca by root exudates and also by various products of microbial activity, which influenced soil exchangeable Ca in soils under rapeseed (Chatterjee et al, 2005). The improvement in soil available S status due to B application was previously reported by Bhupenchandra et al (2021). Furthermore, additions of lime also might have resulted in the net mineralization of organic S and accumulation of sulphate in the soil (Haynes & Naidu, 1991).…”

“…Exchangeable Ca in the subsoil layer with the limed treatments gradually increased with time, which indicated that the downward movement of exchangeable Ca took place only after exchangeable sites of clay minerals in the profile were saturated by Ca 2+ ions (Cifu et al, 2004). Residual effect of lime also accelerated the dissolution of calcium carbonate and other insoluble forms of Ca by root exudates and also by various products of microbial activity, which influenced soil exchangeable Ca in soils under rapeseed (Chatterjee et al, 2005).The improvement in soil available S status due to B application was previously reported by Bhupenchandra et al (2021).

Elucidating the impact of boron fertilization on soil physico-chemical and biological entities under cauliflower-cowpea-okra cropping system in an Eastern Himalayan acidic Inceptisol

“…Similarly, SOC in soil remained significantly ( p ≤ 0.05) ( Table 1 ) unaffected after two years of B application, however, an increment in SOC was observed possibly due to the SOC build-up through regular addition of FYM and desirable changes in biochemical and physical properties of soil ( Ghosh et al, 2012 ; Bhupenchandra et al, 2022 ; Harish et al, 2022 ; Kumar et al, 2022 ). Also, another reason for the improvement in SOC could be due to the formation of a strong diol complex of B with organic matter in soils and the capacity of organic matter to improve CEC of soils ( Bhupenchandra et al, 2021b ). Increase in available N could be due the release of mineralized N by the addition of organic matter along with the concurrent release of N via symbiotic biological N fixation by cowpea roots, since B plays a vital role in biological N fixation and upsurges the number of effective nodules ( Bolaños et al, 2001 ).…”

The improvement in the status of available P could be explicated by the existence of positive interaction between P and B in the soil as both are in anionic forms and might have been involved in anion exchange ( Bhupenchandra et al, 2021b ).…”
