Abstract

Soil organic carbon (SOC) plays a vital role in terrestrial C cycle, affecting soil sustainability and its quality and environment. The soil and environmental conditions of cultivated soils in semi-arid regions are favorable for rapid decomposition of SOM resulting in high rates of C loss to the atmosphere, contributing to global warming. Application of organic amendments is an important strategy to enhance SOC storage, soil fertility, water retention, crop productivity and atmospheric C mitigation. A 2-year field experiment was conducted at the research farm of Nuclear Institute for Food and Agriculture (NIFA), Peshawar, Pakistan to study the effect of 4 organic wastes with and without NPK mineral fertilizers on SOC retention, water use efficiency (WUE) and maize yield under an irrigated wheat-maize cropping system. The wastes included municipal solid waste (MSW), filter cake (sugar industry waste), farm yard manure (FYM), and wheat crop residues. The C: N ratio of the organic wastes ranged from 8.0 in the filter cake to 100 in the wheat residues. All organic wastes were applied at a rate of 3 t C ha-1 alone and with a full or half dose of NPK mineral fertilizers. Soil analysis revealed that on average, filter cake and MSW as sole treatments successfully increased the total SOC content in the 0-15 cm soil layer by 7.7 t ha-1 and 5.8 t ha-1 respectively. The MSW + full NPK fertilizer treatment accumulated the highest amount of SOC (9.4 t ha-1) followed by the filter cake + NPK treatments (8.2 t ha-1). On average, maximum maize grain WUE (20.7 kg ha-1 mm-1) and grain yield (4439 kg ha-1) were obtained by the combined application of filter cake and full NPK followed by MSW + NPK treatment. These results indicate that among the organic wastes, filter cake and MSW have the best potential for improving SOC retention, WUE and maize yield in irrigated wheat - maize cropping systems in warm semi-arid areas.

Keywords: Soil carbon sequestration, water use efficiency, maize, Organic amendments.
