Description Research article
Uneven distribution and intensity of rainfall in subtropical semi-arid Vertisol creates different hydro-climatic
condition due to its mineralogy and expansive type of clays. Indeed, information on impact of moisture levels on
soil C- and N-mineralization in presence of residue and recommended fertilization is scarce. Thus, this incubation experiment was conducted at ICAR-Indian Institute of Soil Science, Bhopal during 2018–19 with four moisture, two fertilizer, and two residue levels to evaluate the effects of fertilization and residue incorporation on moisture sensitivity of soil C- and N-mineralization. Application of fertilizer induced positive priming effect for CO2-C and increased by ~ 28%. Residue- and fertilizer × residue accelerated the Ccum by ~108 and 125%, respectively. Residue application caused initial N-immobilization. A significant interaction was observed among fertilizer, residue and moisture content for both C- and N-mineralization. C-mineralization was amplified with increase in soil moisture content from 24 to 40% moisture levels, but decreased at 48% moisture level. Irrespective of fertilization moisture sensitivity of C and N mineralization was reduced by residue incorporation. But, fertilization led to highest moisture sensitivity of N-mineralization. Thus, residue incorporation could be recommended as obligatory practice in sub-tropical Vertisol to decrease its moisture sensitivity and to maintain positive C balance and soil health.
