Abstract

This study aims to determine the characteristics of soil pores and therelationship of pore characteristics with soil permeability. Soil samples were collected from Punagaya Village, Bangkala District, Jeneponto Regency, South Sulawesi. Soil samples were taken from 20 observation points representing two types of land use ie cultivated land and fallow field at a depth of 0-60 cm. Soil analysis (pH, organic material, C-organic, cation exchange capacity, bulk density and soil texture), Pore characteristics(porosity, pore distribution and pore stability), and permeability. Analysis of soil properties and pore characteristics was descriptive, while the relationship between pore characteristics and permeability was analyzed by single or multiple regression and correlation analysis. The results showed that the permeability of soil vertisol 0.29 cm/h (slow) and the average value of soil pore characteristics of vertisol as follows: porosity ranged 56.49%, fast drainage pore 4.35%, water pore available 17.8% And 32.5% micro pores, and 36.46% pore stability. Based on the regression and correlation test, it is known that Porosity and porosity and pore stability index have the greatest influence on permeability.

Abstract

Nickel mining decreases the quality of soil properties, it is not suitable for agriculture so alternative technology is required such us using biochar made from oil palm empty fruit bunch and mycorrhiza. This study aims to examine the effect of biochar made from oil palm empty fruit bunch and mycorrhiza to improve the nickel post-mining soil quality. This study used two-factor factorial randomized group design. The first factor is biochar made from oil palm empty fruit bunch with 4 levels; B0 (0 g), B1 (300 g), B2 (450 g), and B3 (600 g), the second factor is mycorrhiza with 4 levels; M0 (0 g), M1 (2 g), M2 (4 g), each treatment was repeated 3 treatments so that the total experiment was 36 units. The results showed that the use of bio-ameliorant waste from oil palm empty fruit bunch with dosage of 120 g / kg, improved the chemical properties of nickel post-mining soil regarding the parameter of C-organic, pH, available phosphorus, cation exchange capacity, exchangeable aluminum, Ca-dd and Mg -dd and increasing plant growth significantly. The treatment of mycorrhiza 0.4 g / kg significantly affected the soil properties regarding the parameters of root volume, root length and percentage of root infection and improvement of soil chemical properties in available phosphorus to plants and exchangeable aluminum parameters. The treatment of biochar with dosage of 120g / kg of soil and mycorrhiza 0.4 g / kg of soil is the best interaction of mycorrhiza and biochar made from oil palm empty fruit bunch as amelioration material of post-mining soil which is characterized by the decrease of exchangeable aluminum value. The application of biochar made from oil palm empty fruit bunch and mycorrhiza can improve the nickel post-mining soil quality

Abstract

The large population growth of Indonesia encourages the transition of the function of agricultural land into non-agricultural land. The demand for land from time to time always increased, while the available land limited in number. This caused the conversion of agricultural land into non-agricultural land. This phenomenon certainly could bring serious problems. This study aimed to determine the land productivity index for rice and green beans cultivation and to find out the factors that influence production. The productivity indexes analyzed based on the Storie Approach. Soil sampling was carried out by an open grid method divided based on five land map units which spread across three different villages in Kampili irrigation area. The results of the study indicate that the highest productivity index is shown in SPT 5 where the productivity index is 47 and the lowest productivity index is shown in SPT 2 where the productivity index is 21,6. The land productivity index in the downstream of the Kampili irrigation area, which is located in the district of West Bajeng is poor to sufficient level. The low value of land productivity was strongly influenced due to poor soil quality, especially soil chemical properties. The results of the laboratory analysis show that nutrients in those areas are low.

Abstract

This study aims to describe the linkage of carbon stocks in secondary forest and oil palm land cover to the amount of CO2 absorbed and the release of O2 to estimate carbon stocks in land cover in secondary forest and oil palm. The research use sample plot size 20 x 50 that taken 9 times for each land cover. Biomass data was collected using non-destructive sampling, since for undergrowth and necromass using destructive sampling by cutting and taking all the undergrowth and litter that are in a 1 x 1 meter quadrant. There are two kinds of soil sampling that collected; disturbed soil and intact soil. The results showed that the ability of each type of plant had varying values ​​of carbon stock, CO2 absorption and oxygen release on land cover. The value of carbon stock, CO2 absorption and oxygen release respectively on land cover, namely on secondary forest land cover is 265.86 tons / ha, 974.82 tons / ha and 708.96 tons / ha and oil palm is 100.89 tons / ha, 369.93 tons / ha and 269.04 tons / ha.
