Abstract

ABSTRACT Entisols Palu including the area Poboya formed under the influence of a dry climate with the parent material which is dominated miniral quartz, very resistant to change arid climate causes weathering chemical reactions in the soil is slow, Activity processing of gold amalgamation using a mercury/mercury result in the loss of top fertile soil and polluted that will affect environmental conditions soil. Research is done to determine the effect of Humic and Fulvic Acid Extract Against Compost Thitonia diversifolia HgKhelat, pH and Org-C Entisol Contaminated Mercury. This study was arranged in a randomized block design (RBD) consisting of 6 dosage: control (without humic acid and fulvic acid), humic acid and fulvic acid at a dose of 50 ml/kg, 75 ml/kg, 100 ml/kg, 125 ml/kg, and 150 ml/kg soil, each treatment was repeated three times to obtain 18 units of experiment, results showed that the extract humic acid and fulvic acid compost Thitonia diversifolia up to a dose of 150ml/kg soil during incubation time for 30 days the significant and proven effective against changes in the Hgchelate were able to raise Hg-chelate, the pH of the soil and C-entisols Organic soil polluted with mercury. Key Words : Entisols Contaminated mercury, Humic acid and fulvic acid Tithonia,

Abstract

The research aimed at identifying the morphology of mycorrhizal arbuscular fungi (MAF) on the root zones of different horticultural crops (peppers, potato, leek, cabbage, tomato and chicory) in Nupabomba village Tanatovea sub district of Donggala.  It was descriptive exploratory study and conducted from October to December 2015. Samples of soil were purposively taken around the root zone and analyzed for its chemical and physical characteristics as well as for mycorrhizae  spore isolation and its identification.  The research results showed that the highest spore number of 303 spores per 10 g was found in the leek plantation whereas the lowest number of 43 spores per 10 g in the potatoes plantation.  There are four types of spore genus i.e. Acaulaspora, Entrophospora, Glomus and Paraglomu.  The Glomus genus was the dominant spores found in all types of the horticultural plantations.

Abstract

This study aims to determine the density and diversity of spores of Arbuscular Mycorrhizal Fungi (AMF) at rhizosphere of several plantation crops, such as ; cocoa (Theobroma cacao L.), coconut (Cocos nucifera L.), aren (Arenga pinnata Merr), candlenut (Aleurites moluccana L.),     and bush. Soil sampling was taken by descriptive exsplorative method. Soil samples of rhizospheres of several industrial plants, had been taken from January to March, 2018. Enumerations of spores conducted in Laboratory of Soil Science Department, Faculty of Agriculture, University of Tadulako. Horizontally, the most spores numbers of AMF were found on the rhizosphere coconut in a distance of two meters from stand of plant, that weres 119 spores in 10 g of soil, the lowest spores number were found on the rhizosphere of cocoa in a distance of one meters from stand of plant, that were 15 spores in 10 g of soil. Vertically, the most spores numbers were found on the rhizosphere of aren plant in a depth of 40 cm, that were 98 spores in 10 g of soil. The lowest spore number were found on the rhizosphere of cocoa in a depth of 40 cm, that were 14 spores in 10 g of soil. The analysis of the diversity of colors found there are nine kinds of different colors, includes the yellow clear color, yellow, yellow green, reddish yellow, red, red brown, brown, brown black, and black. The spores are found is dominated by the color of black that is 337 spores, then the color of red being the color of most little found which amounted to a total of 15 spores.
