Abstract

Methane (CH4) is an important greenhouse gas that has a high heat trapping capacity thus potentially contribute to the global-warming.  Agriculture is considered among the responsible emission sources of CH4. Relationship among soil characteristics, soil microbes, and CH4 flux is very important in understanding the mechanism involved in the mitigation effects of certain agriculture practices. Results of this research showed that rice field produced the highest CH4 flux (7.4976 ± 0.5299 mg CH4-C m-2 h-1, n=3), while vegetable, sweet potato, yam bean and corn cropping produced lower CH4 flux (-0.7708 ± 0.6434 to 0.4605 ± 0.5255 mg CH4-C m-2 h-1, n=3). Nitrifier population among cropping systems was 3.13x103 to 3.17x104  MPN g-1 soil (dry weight), while denitrifier population was 3.77x103 to 1.17x105 MPN g-1 soil (dry weight).  There were no specific dominance proportion of nitrosomonas, nitrobacter, denitrifier and total propagule among cropping systems. The CH4 flux had highly correlation to soil water content (r = 0.951), soil pH (r = 0.852) and soil Eh (r = -0.982). Denitrifier had significantly correlation to soil pH (r = -0.635) and soil ammonium content (r =  -0.681).   Key words :  CH4 flux, cropping system, soil characteristic, soil microbes

Abstract

There are two main problems when system of rice intensification (SRI) cultivation is carried out at tidal areas, e.g. the presence of Fe which is potentially toxic to plants and low nutrients availability. Utilization of Azotobacter-enriched compost is a choice to overcome iron toxicity as well a source of nutrients. The aims of this research were to study the effect of Azotobacter enriched compost to reduce the rates of inorganic fertilizers applied, to increase the efficiency of N, P, and K uptake, and to increase plant growth and yield. Two rice cultivation methods were applied namely SRI and conventional rice cultivation methods on tidal lands (rice fields) of South Kalimantan. A completely randomized block design with two factors was applied. The main plots were SRI and conventional rice cultivation, and as subplots were eight types of fertilizer that is a combination between Azotobacter-enriched compost with inorganic fertilizers rates. The results showed that soil nutrient availability, uptake and efficiency of N, P, and K with SRI technique was higher than conventional cultivation. Azotobacter- enriched compost on the tidal land (rice fields) could reduce the use of N and K fertilizer by 25%. Furthermore, the efficiency of N and P uptake in enriched compost with 75% of fertilizer N, P, and K were not different with enriched compost with 75% of fertilizer. Ciherang rice yields with SRI cultivation was approximately 22% higher compared to that from conventional rice cultivation. Keywords: Azotobacter-enriched compost, conventional rice cultivation, inorganic fertizers
