Abstract

Soil sampling was carried out at PT. Wijaya Inti Nusantara, Torobulu Village, Laeya District, South Konawe Regency.This study used a randomized block design (RBD) consisting of 7 treatments, namely: B0D0 = without amelioran, B1DI = ameliorant of rice husk 50g/polybag, B1D2 = ameliorant of rise husk 100g/polybag, B1D3 = ameliorant of rice husk 150g/polybag, B2D1 = ameliorant of sawdust 50 g/polybag, B2D2 = ameliorant of sawdust 100 g/polybag , and B2D3 = Amelioran sawdust 150 g/polybag, each treatment was repeated 3 times and 21 research units were obtained.The results of the study on the effect of ameliorants on the growth of patchouli plants in ex-mining soil showed that the highest treatment was C-organic B2D3 3.38% (T), water content B1D3 34.5% week 4, and aggregate stability B1D1, B1D2 , B1D3 (3) Total Slanging.The effect of using ameliorant on the growth of patchouli plants in ex-mining soil has an effect on plant height and biomass variables compared to no treatment. The best results were found in the B2D3 treatment.Keywords: ameliorant, patchouli, rice husk, sawdust

Abstract

This study aims to determine some of the physical and chemical properties of the soil on different lands in Lasori village Mawasangka Timur district cental Buton District. Soil samples were analyzed at the UPT. University integrated laboratory halu oleo. This research is a descriptive study using the observation method, namely taking samples in the field and analyzing them in thelaboratory to obtion quantitative data. Point determination is carried out using a random method sampling. The land used is a corn sample point and cassava sample point. There were 6 sample units from different land to represent 1 land. The results showed that the physical and chemical properties of the soil on different land in Lasori village Mawasangka Timur District central Buton Tengah. The parameter were very high that becomes the limiting factor for physical properties is bulk density with 1,00 g/m3 – 1,36g/m3 with low – medium criteria. The soil textures are dusty loam and sandy loam. Porosity with 48.12% - 62,18%, diamond not good. While limiting the factor for chemical properties is soil pH with a value of 6,38 – 7,68, a dlighty acidic to slightly alkaline content of C-organic with a vaule of 2,27% - 5,28% moderate-high index and KTK with a value of 35,26 me/100g – 58,36 me/100g with a high – very high index. Keywords: Soil physical, corn, soil chemical, cassava.
