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

Soil physical characteristics refer to the depth of soil drainage and soil structure and influence root development and water availability, the drainage of which influences oil palm plant production. This research aims to analyze the condition of soil physical properties on different slopes and their relationship with oil palm production located at PT. Tani Prima Makmur, with coordinates 3°00′ – 4°25′ South Latitude and 121°73′ – 123°15. Namely Afdeling of Lawulo, Anggotoa, and Wawotobi. Analysis includes soil texture, water content, organic matter, total pores, permeability and slope class. Using the survey method, Soil samples were taken in three sections with 3 slope classes, namely sloping (0-15%), slightly steep (15-25%) and steep (25-45%). Soil samples were taken to the Soil Science Laboratory. The research results show ed that Soil in the three subdivisions the a variety of textures from sandy loam to clay, water content tends to be high (16,92%-25,75%). The organic matter content (2.15%-5.09%), while the bulk density is high (1.35-1.86 g cm-3), indicates a fairly significant level of soil density. Soil permeability varies from moderate to very slow (1.96-2.75 cm h-1), especially in Afdeling Lawulo. Total pore space (30%-49%). Production data on lower slopes has a higher FFB weight than steeper slopes. Proper soil management is needed to increase oil palm productivity, especially in maintaining a balance between water retention and good drainage in each planting area
