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

Lahan pertanian, terutama di daerah tropis seperti Indonesia, umumnya telah mengalami proses degradasi secara intensif, yang dipicu oleh tingginya intensitas curah hujan dan praktek pemanfaatan lahan yang kurang  mengindahkan prinsip konservasi tanah dan air. Akibatnya, telah terjadi kerusakan lingkungan dan penurunan tingkat kesuburan tanah-tanah  pertanian dari tahun ketahun, dengan konsekuensi berupa makin rendahnya produktifitas lahan-lahan pertanian tersebut. Penelitian yang dilaksanakan di  Kecamatan Parangloe, Kabupaten Gowa, Provinsi Sulawesi Selatan ini, bertujuan untuk mengevaluasi  status kerusakan tanah pada lahan budidaya pertanian (lahan kering/cabe, lahan kering/jagung, lahan kering/rambutan dan sawah),  dan dibandingkan dengan status kerusakan tanah pada areal non-budidaya (hutan sekunder, semak belukar). Metode penilaian status kerusakan tanah yang digunakan adalah sesuai PERMEN LH No. 07 Tahun 2006 tentang Tata Cara Pengukuran Kriteria Baku Kerusakan Tanah Untuk Produksi Biomassa.  Hasil studi mengindikasikan bahwa, dengan menggunakan kriteria  Status Kerusakan Tanah pada PERMEN LH No. 07 Tahun 2006 maka, tidak ditemukan adanya perbedaan status kerusakan tanah antara areal bididaya dan areal non-budidaya. Dengan kata lain, parameter yang digunakan untuk menilai Status Kerusakan Tanah pada PERMEN LH No. 07 Tahun 2006 ini, kurang sensitif dipakai untuk menilai perbedaan status kerusakan tanah pada areal budidaya dan areal non-budidaya.
