Abstract

Vegetation type changes some soil properties such as bulk density, nutrient absorption and soil organic carbon. Nutrition management of lawn plant is an important factor which affects soil properties in lower layers. The application of biofertilizers enhance the quality of soil and enhance the growth of lawn plant and in addition they are ecofriendly. The purpose of this study was to investigate the effect of urea and biofertilizer containing nitrogen-fixing bacteria (Pantoea agglomerans) on some quality characteristics of soil under lawn plant cultivation. This experiment was conducted in a completely randomized design in a greenhouse condition with three replications. Treatments include: 1-Control (Br), 2- lawn plant cultivation (Speedy Green) by conventional method (Gr), 3- lawn plant + urea (GrU), 4- lawn plant + bio-fertilizer containing Pantoea agglomerans (GrPA), and 5- lawn plant + Pantoea agglomerans + growth promoting bacteria (GrPP). The fresh weight of lawn plant was measured along with some soil properties. The results showed that lawn plant and application of biofertilizer containing Pantoea agglomerans shaped larger soil aggregates than control but they had no significant effect on aggregate stability. Biofertilizers and urea increased the growth of lawn plant. Cultivation of lawn plant increased soil organic carbon, total nitrogen, phosphorus and potassium uptake, but the effect of biofertilizers was not significant. The highest amount of total nitrogen and soil organic carbon observed in urea fertilizer treatment. In general, the use of biofertilizers in lawn plant cultivation is recommended.
