Cím:	Complex effect of secondary salinization and composting on soil respiration / József Zsembeli, Yuriko Mori, Géza Tuba, Krisztina Czellér, Györgyi Kovács
Dátum:	2017
Megjegyzések:	Salt-affection has been and still is a critical issue facing croplands in a large portion of the GreatHungarian Plain. Compost is known to have a positive effect on salt-affected soil, but little is known about thecorrelation between soil organic matter and bacterial activity. Microbial biomass and activity is found to berelative to levels of soil organic matter (SOM). Bacterial activity is affected by both salts and organic matter, andthis research aims to determine the breakpoint and relationship between those two parameters. A pot experimentwith 27 pots was set in Karcag Research Institute of RISF UD where soil respiration was measured undercontrolled conditions over a 16-week-long period. During the initial phase of the experiment, compost wasadded to non-salt-affected soil in differing doses (0, 25, 50 t/ha), and each sample was irrigated with a solutionof different salt concentrations (0, 600, 1800 mg/l) with three test replications. At the tenth week, the compostwas added to each at second time. At the thirteenth week, soil conditioner, rich in N, S and Ca, was addedequally to each soil sample. Following the experimental phase, nutrients and bacterial colony measurements wereconducted. During the phase of the experiment with compost application alone, the results demonstrated thatsalt concentration of irrigation water and compost ratio had negligible influence on soil respiration. However,following the addition of soil conditioner, a dramatic increase in respiration was recorded with initial spike ofchemical reaction and second spike with biological reaction. Nutrient components were highly affected by saltand SOM, therefore, soil microbial activity fluctuates with variable reasons including combination of nutrientsunder salt stress environment.
