| Abstract/Contents: | "Soil health is an assessment of how well soil performs and preserves its functions. Among soil health parameters, aggregates stability and microbial community structure are two of important indicators. In this study, five forage systems including 1) Conventional tilled annual ryegrass (Lolium multiflorum) for winter grazing, 2) No-tilled annual ryegrass for winter grazing, 3) No-tilled annual ryegrass with white clover (Trifolium repens) for winter grazing, 4) No-tilled bermudagrass (Cynodon dactylon L.) for summer grazing, and 5) No-tilled multispecies pasture including Alyce clover (Alysicarpus vaginalis), perlit millet and cowpeas (Vigna unguiculata) for summer grazing were evaluated for their impact aggregate stability and microbial community response. No-till annual ryegrass system showed greater fraction in macroaggregates (>2mm and 0.25-2mm), but less in microaggregates (0.53-2mm) and silt+clay (<0.53mm), compared to conventional tilled annual ryegrass system. For no-till annual ryegrass systems, the addition of white clover significantly increased macroaggregates fraction and the N content in all aggregate and silt+clay fractions. Analysis of soil microbial phospholipid fatty acid (PLFA) showed that ryegrass with clover system and the multispecies pasture system increased overall microbial biomass as well as fungi populations. Ryegrass with clover system also showed significant increase in the ratio of Gram-positive to Gram-negative bacteria, as well as the greatest nutrient stress level to Gram-negative bacteria based on the cyclopropyl monounsaturated ratio of (cy17:0 ω7c + cy19:0 ω7c) / (16:1 ω7c + 18:1 ω7c). Overall, the results suggest that no-till and the inclusion of legumes such as white clover have a great potential in improving soil health parameters relating to physical and microbiological properties for forage systems." |
