Abstract

Limestone post mining soil had high levels of calcium carbonate and pH, this condition causing a lack of soil P availability, so the application of mycorrhizae and organic matter is necessary. This study aims to determine the effect of mycorrhizae and organic matter, and the best combination of mycorrhizae and organic matter on soil P availability of limestone post mining and growth of maize. This study was conducted at Greenhouse in Taman Teknologi Pertanian Lebaksiu, from February to May 2019. This study used a Completely Randomized Design two factors. The first factor was the dose of mycorrhizae, namely without mycorrhizae (M0), mycorrhizae 10 g / pot (M1), and mycorrhizae 20 g pot (M2). The second factor was organic matter, namely without organic matter (B0), cow manure 20 tons / ha (B1), corn litter 20 tons / ha (B2), and legumes liter 20 tons / ha (B3). Each treatment was repeated 3 times. The result shows that the aplication of mycorrhizae had a significant effect on the increasing C-organic soil, Cation Excange Capacity (CEC), plant height and plant dry weight, but it did not significantly affect on P-available, Ca and Mg. The application of various types of organic matter had a significant effect on the increasing P-available, C-Organic soil, CEC, plant height, and plant dry weight, and decreasing soil pH (H2O) and Ca, but it did not significantly affect on Mg. There was an interaction between mycorrhizae doses and organic matters on the increasing plant dry weight of 6 WAP.
