Impact of Application Rates of Pre-planting Liming Fertilizers on Changes in Soil Chemical Properties and Growth of 'Melody Yellow' Pansy in Plug Production

摘要: Abstract. Objective of this research was to investigate the influence liming fertilizers on changes in soil chemical properties and growth pansy ‘Melody Yellow’ plug production. To achieve this, dolomite (DO) with 0, 1.0, 3.5, 8.0 or 13.0 g･L -1 calcium carbonate (CC) 2.0, 2.5, 3.0, 4.0 application rate were incorporated into peatmoss + vermiculite (1:1, v/v) during formulation. The treatments 3.5 DO 2.5 3.0 CC had acceptable range solution pH such as 5.6-6.2. Faster rising observed root media containing rather than those DO, indicating higher solubility CC. Ca concentrations all 2 times high DO. highest Mg concentrations, but lower control that additional applications are required. elevated resulted increase fresh dry weight; however, plant heights not influenced by fertilizers. results tissue analysis showed contents, did contents other nutrients N, P, Fe, Mn, Zn Cu.
