Abstract

Nyatoh (Palaquium obtusifolium Burck) is a type of tree that is very much in demand by local and international communities. Nyatoh stands (Palaquium obtusifolium Burck) which is adjacent to the agricultural crops owned by residents in the village, is interesting because it will show that, the level of soil fertility is influenced by vegetation. Not only that, according to local residents, after the land was planted with Nyatoh plants (Palaquium obtusifolium Burck) erosion and landslides had not occurred again.The research was conducted from October to December 2017 located in the village of Sindosa, Sindue Tobata district, Donggala district. This research was started from a field survey, determination of sampling points, soil sampling and analysis of soil samples in the laboratory of the Faculty of Agriculture, University of Tadulako. Soil sampling is done by taking intact soil samples at several predetermined locations namely peaks, backs, and valleys. Each slope is determined by 5 soil sampling points to represent each location with 2 types of depth, namely 0-30 cm and 30-60 cm. Then the samples obtained from these 5 points will be compiled. From the three locations there were 30 soil samples before they were compiled. Overall soil samples after being compiled will get 6 soil samples analyzed at the Soil Science Laboratory of the Faculty of Agriculture to determine the chemical condition of the soil. Data obtained from the laboratory are then analyzed descriptively, namely by describing the chemical properties of the soil, namely pH, CEC, C-Organic and soil organic matter.The results showed an average pH with a depth of 0-30 cm, which is 6.64, while at a depth of 30-60 cm showed a pH with an average of 6.43, Cation Exchange Capacity (CEC) on average below the Nyato stand at Sindosa village Sindue Tobata District Donggala Regency at a depth of 0-30 cm, which is 25.87 (cmol (+) kg ¹) is in the medium category, while at a depth of 30-60 cm is 3.23 (cmol (+) kg kedalaman ¹) belongs to the very low category. The C-Organic content at a depth of 0-30 cm with an average of 2.45 is included in the medium category and at a depth of 30-60 cm that is 0.65, including very low. The content of Soil Organic Materials (BOT) with an average depth of 0-30 cm, which is 4.23 included in the high category and at a depth of 30-60 cm with an average of 1.11 is low.

Abstract

Watutau Village is one of the villages in the Napu valley plains of Central Sulawesi, can be found stands pine breadth ± 500ha. In addition to pine stands there are also grasslands, which are located adjacent to pine stands, it attracts attention for research because it has two distinct land cover vegetations. Differences in vegetation composition of land cover can also affect the physical condition of the soil. The purpose of this study was to determine the physical condition of the soil under the stands of pine and grassland. The study was conducted from November 2017 till January 2018, located in Watutau Village, Lore Peore Sub-district, Poso District, Central Sulawesi. This research starts from field survey, location determination, soil sampling, analysis of soil sampled laboratory. Determination of location done purposive sampling by considering slope condition that is section of valley, slope and peak. Soil sampling is done at two depths 0-30cm and 30-60cm. The results showed that the soil under pine stands had dust clay soil texture and clay, granular soil structure, bulk density 1.26gr / cm3 (High) and 1.3gr / cm3 (High), porosity 50.2% (Good) and 48.6% (Less good). Permeability 2.45cm / hr (Medium) and 2.9cm / hr (Medium), soil colors yellowish red, very dark gray, gray irish, very dark grayish brown, grayish brown. While the soil conditions in the grassland area have clay soil texture, granular soil structure, Bulk density 1,34gr / cm3 (High) and 1,4gr / cm3 (Very High), 50% Porosity (Good) and 47,63% Not good), Permeability 2.14cm / hr (Medium) and 3.66cm / hr (Medium), soil colors dark grayish brown color, brown, strong brown.

Abstract

Primary Forest and Imperata cylindrica grasslands are two different ecosystems that meet in the same area in Lore Lindu National Park. Climatic conditions such as rainfall are also the same. The difference in vegetation between the two ecosystems is interesting to be investigated by comparing the physical properties of the two ecosystems. This study aims to determine the physical properties of soils in the Primary forest and Padeha grasslands in the Lore Lindu National Park Area. This research was conducted from January to March 2017, located in the Lore Lindu National Park, Sedoa Village, Lore Utara District, Poso Regency, Central Sulawesi. This research was started from a field survey, determining the location of sampling, soil sampling, analysis of soil samples in the Laboratory. Determination of the location is done intentionally (purposive sampling) by considering the slope conditions namely, valley back and hill. Soil sampling was carried out at two depths namely 0-30 cm and 30-60 cm. Soil in primary forest has physical properties as follows: clay soil texture, medium granular and coarse granular soil structure, high bulk density 1.2 gr / cm3 and very high 1.5 gr / cm3, good soil porosity 54.5% and less good 43.6%, moderate soil permeability 5.12 cm / hour and 0.57 cm / hour rather slowly, and the color of the soil is dark yellowish, yellowish brown, strong brown. Soil in Padeha grasslands has the following physical properties: clay soil texture, rough granular soil structure and medium granular soil, high bulk density 1.3 gr / cm3 and very high 1.4 gr / cm3, good porosity 50.3% and bad 35 , 9%, moderate permeability 2.2 cm / hour and rather slow 1.46 cm / hour, and the color of the soil is strong brown, brown, and black.

Abstract

The area of pine stands 25 year old are 500 ha grow at advacent of grassland. The pine stands and grassland have different effect on chemical properties of soil. The objective of tree study are to determine the soil chemical propertie of pine stand and grassland. The research was conducted from November 2017 to January 2018, located at pine and grassland area of Watutau Village, Lore Peore Sub-district, Poso District, Central Sulawesi. Analysis of chemical properties of soil samples including pH, C-organic, N-total, P-available, K-total and CEC was conducted at the Soil Science Laboratory, Faculty of Agriculture, Tadulako University. The results showed that pine stands had soil chemical conditions at a depth of 0-30 cm lower in (C-organic, P-available, K-total, and CEC) but higher in pH and N-total than on grassland areas. The soil chemical conditions in pine stands consist of pH 4.90 acid, C-organic 0.55% very low, N-total 0.09% very low, P-available 5.26 mg / 100g very low, K-total 11 , 81 mg / 100g low, CEC 4.29 cmol (+) kg-1 is very low. While soil chemical conditions on grassland area consist of pH 4.79 acid, C-organic 1.61% low, N-total 0.08% very low, P-available 9.24 mg / 100g very low, K-total 19.45 mg / 100g average, CEC 4.76 cmol (+) kg-1 is very low.

Abstract

Soil microorganism populations are also affected by land use forms, such as agroforestry and mixed farms. The population of soil microorganisms also form an inseparable system of life from minerals and organic matter in the soil. This study aims to determine the population of fungi and soil bacteria in agroforestry and mixed garden. This research was conducted in December 2017 until January 2018. This research started from field survey, determination of soil sampling point. Soil sampling was done on plot with size 20 m × 100 m with a soil depth of 0-10 cm and composite soil sampling ie each soil sample is represented by one same land bed. This research uses descriptive analysis method, that is by interpretation of soil biology condition data obtained from the laboratory as facts describing soil conditions in the field. The results showed that the population of soil fungi and bacteria differ between agroforestry and mixed garden. The highest number of land fungi population at the mixed garden site (811 x 103 CFU g-1), whereas the lowest fungi population at the Agroforestry Land location (20.1 x 103 CFU g-1), the highest population of soil bacteria at the Mixed Garden location (10,38 x 106 CFU g-1) whereas in Agroforestry Land has the lowest total population (33.1 x 106 CFU g-1).
