Abstract

Sand-mining can damage to physical, chemical and biological soil properties. Land reclamation is one of method that can be use to solved that problem. Adding soil ameliorant and revegatation are known can improve soil productivity. The objective of this study was to determine the effect of soil ameliorant, which is organic fertilizer and biofertilizer in improving soil organic-C and root infection of dragon fruit (Hylocereus costaricencis L.) by AMF on soil originated from Sand Mining, Sumedang, Indonesia. Greenhouse experiment was conducted at Faculty of Agriculture, Universitas Padjadjaran from December until June 2013. The experiment used was Factorial Randomized Block Design consist of two factors and three replications. The first factor was biofertilizer which consist of: without biofertilizer, AMF and AMF + MHB (Mychorriza Helper Bacteria). The second factor was organic fertilizer that consist of: without organic fertilizer, chicken manure, goat manure, cow manure, rabbit manure, cocopeat and Organic Granule Fertilizer (each 5 kg / pot). Results of experiment showed that there was interaction effect between organic fertilizer and biofertilizer in improving soil organic-C. There was no interaction effect between organic fertilizer and biofertilizer to root infection.

Abstract

Hydroponics is one of the urban farming techniques that can be used to improve crop yield. Nowadays, the supply of all nutriens in hydroponics, particulary phosphate only derived from inorganic fertilizers. Application of arbuscular mycorhiza fungi (AMF) as bioagent may help plants to fill its nutrient need, especially phosphate. This study aimed to find out the best concentration of phosphate fertilizer to be applied to the hydroponic Ebb-flow system model. The stage was to test several vegetable plants with various concentrations of phosphorus (0, 20, 40, 80 ppm) on the Ebb-flow hydroponic system. Vegetables used were romaine lettuce, red lettuce, and kale. Interaction was found between vegetables and the variety of phosphate concentrations and the root colonization by AMF, and phosphate uptake. The AMF applications on the hydroponic Ebb-Flow system model reduced phosphate fertilizer need by 40 ppm (50%), on red lettuce 0 ppm (100%), and on kale 20 ppm (25%). Besides lowered phosphate doses, such applications also increased the plant yield.
