Effects of soil compaction and moisture on Juncus tenuis growth

Juncus tenuis Willd. is a warm-season, perennial weed of turfgrass. In wet and compacted soils, it well documented, yet little known regarding the interaction effects compaction soil moisture on its rooting foliar growth. A greenhouse experiment examined above- belowground growth J. tenuis. The experimental design was completely randomized with 3 × arrangement four replications two runs. Factors included (bulk densities 1.56, 1.77, 2.00 g cm–3) (10.9, 27.9, 59.6% volumetric water content). transplanted into pots, acclimated for 7 d, subjected to treatments 10-wk period. Foliar harvested every 2 wk root destructively assessed. Cumulative biomass varied in response moisture; however, no significant interactions were detected. effect accounted 15 12% explained variation, respectively. Increasing bulk density from 1.56 cm–3 reduced by 29 40%, Soil ≥84% variation biomass. 10.9 increased 150 230%, results suggested that cultural practices prioritize modification while alleviating may reduce presence within maintained
