Acid soil is commonly grown with cassava, which in general, tolerate low soilÂ fertility and aluminum (Al) toxicity. However, without any improvement efforts such soil will become worse. Intercropping cassava with Brachiaria decumbens (BD) which adapts to acid soil and tolerates low fertility soils as well as application of arbuscular mycorrhiza (AM) and organic matters are among the important efforts to rehabilitate this soil. The experiment was conducted toÂ examine the impact of BD, AM, and potassium (K) enriched rice straw compost on exchangeable Al, available K, and stability of soil aggregates. Experiment was arranged in a completely randomized design with three factors and three replications. The first factor was BD as cassava intercropping, the second factor was AM, and the third factor was 2 t ha-1 rice straw compost enriched with 0 kg, 50 kg, 100 kg, and 200 kg KCl ha-1. Brick pots (1 m length x 1 m width x 0.45 m depth) filled with Kanhapludult soil was used for growing cassava in which row of BD was planted at 60 cm from cassava stem. K-enriched rice straw compost and AM (10 g per stem) were applied around cassava stem at 2 and 12 days after planting, respectively. BD was cut every 30 days and the cutting was returned to the soil. Soil exchangeable Al was analyzed at 0, 3, 6 and 9 months after planting (MAP), while Al and K contents as well as aggregate stability were measured at 6 MAP. The results showed that planting BD decreased 33% exchangeable Al, which means that the root exudates of this grass was effective in detoxifying Al3+. Treatment of BD and/or in combination with AM was effective in preserving K added to the soil, increasing total polysaccharides, and improving soil aggregate stability. This indicated that planting BD and applying AM and Kenriched rice straw compost improved acid soil fertility, and therefore can be recommended in cassava cultivation.

The Effect of Water Management and Rice Genotypes to Against Toxicity of Iron and Productivity of Rice in Tidal Land Type B in South Sumatera. Tidal land is one of the alternative land to support increased productivity of rice, but rice productivity in this area is still low, and the land utilization is not optimal yet. One factor is high iron content in the soil that can be toxic to plants. The purposes of this study were (1) to determine the effect of water management and rice genotype, as well as their interaction on the percentage of leaf bronzing, growth and yield of rice in tidal lands, (2) to select an alternative combination of water management and rice genotypes that may increase rice yields in tidal land. This study was conducted from February until June 2013 in the tidal area with type B overflow, Mulia Sari village, Banyu Asin regency, South Sumatera. The experimental design used was a split plot design with three replications. The main plot was water management with four levels, while the subplot was rice genotypes consisted of three genotypes. The results showed that water management and its interactions with plant genotypes had significant effect only on the percentage of bronzing, Fe content in shoot, and Fe content in root crops, while the plant genotype significantly affected all observed variables. The use of genotypes tolerant to iron toxicity (Indragiri) combined with (form stagnant and saturated water management) drainage with intervals of two weeks could give yield 6.8 and 6.2 t/ha respectively.Keywords : Water management, genotype paddy, tidal landABSTRAKLahan pasang surut merupakan salah satu lahan alternatif untuk mendukung peningkatan produksi padi, tetapi produksi padi di lahan ini masih rendah, dan pemanfaatan lahannya belum optimal.

Kendala terbesar kegiatan evaluasi lahan di Indonesia adalah ketersediaan dan kelengkapan data sumberdaya lahan skala semi detil maupun detil. Meskipun data sumberdaya lahan pada skala tersebut tersedia namun data mengenai sifatkimia dan biologi tanah seringkali tidak lengkap. Untuk mengantisipasi permasalahan tersebut, penelitian ini bertujuan untuk mengkaji penerapan metode evaluasi lahan alternatif untuk identifikasi lahan sawah, yaitu metode ekstrapolasi. Metode ekstrapolasi dimulai dari identifikasi karakteristik lahan yang mencirikan keberadaan lahan sawah, penentuan kelas dan skor karakteristik lahan penciri menurut tingkat kecocokan lahan sawah, identifikasi nilai skor total berikut klasifikasi tingkat kecocokan lahan sawah akhir yang terjadi di lahan sawah, dan ekstrapolasi spasial tingkat kecocokan lahan sawah akhir ke seluruh area kajian. Hasil penelitian menunjukkan bahwa karakteristik lahan yang mencirikan keberadaan lahan sawah adalah kemiringan lereng, curah hujan, jarak dari jalan, dan jarak dari sumber air. Perbandingan metode ekstrapolasi dengan metode evaluasi kesesuaian lahan maupun evaluasi kemampuan lahan menunjukkan bahwa metode ekstrapolasi dapat direkomendasikan sebagai metode evaluasi lahan alternatif karena memiliki representasi keberadaan lahan sawah yang paling tinggi, yaitu 97,5 %.Kata Kunci: Evaluasi Lahan, Ekstrapolasi Spasial, Lahan Sawah.ABSTRACTThe main obstacle in land evaluation in Indonesia is the availability and completeness of land resources data, both in semi-detailed and detailed scale. Eventhough land resource data on semi-detailed and detailed scale are obtainable but chemical and biological soil properties data is often incomplete.To anticipate such problems, this research aimed to review the application of alternative land evaluation method for paddy field identification, which is called extrapolation method. The extrapolation method started from the identification of landÂ characteristics that could indicate the presence of paddy field, fortitude class and score of identifier land characteristics according to the paddy field suitability, identified total score and paddy field suitability level that occured in paddy field, and extrapolated paddy field suitability level spatially throughout the study area.

Oksidasi pirit di lahan sulfat masam menyebabkan pH tanah turun sehingga meningkatkan kelarutan aluminium dan besi. Budidaya jenuh air mempertahankan kedalaman muka air tanah dan membuat lapisan di bawahnya jenuh. Penelitian bertujuan menentukan pengaruh kedalaman muka air tanah dan ameliorasi terhadap beberapa sifat kimia tanah dan produktivitas kedelai. Penelitian dilaksanakan di lahan sulfat masam Desa Banyu Urip Kecamatan Tanjung Lago Kabupaten Banyuasin, Propinsi Sumatera Selatan, sejak Juni sampai Oktober 2012. Penelitian menggunakan rancangan petak-petak terpisahdengan 3 ulangan. Faktor utama adalah tinggi air dalam parit 10 cm dan 20 cm di bawah permukaan tanah dengan pembanding budidaya kering. Faktor kedua adalah amelioran : tanpa amelioran, kapur dan abu jerami. Faktor ketiga adalah genotipe Anjasmoro, Yellow Biloxi, Tanggamus dan Lawit. Hasil penelitian menunjukkan interaksi kedalaman muka air dan ameliorasi meningkatkan pH tanah menjadi 4,67; mempertahankan kadar P tanah 10,70 ppm; meningkatkan kadar K, Ca dan Mg tanah menjadi 1,15; 11,70 dan 6,90 me/100 g. Kadar Fe tanah turun menjadi 12,14 ppm sedangkan kadar Al dan kejenuhan Alturun menjadi 2,06 ppm dan 10,36 persen. Tanggamus memiliki produktivitas tertinggi (2,47 t/ha) karena memiliki lebih banyak jumlah daun (31,5), jumlah cabang (4,5 - 5,3), jumlah buku produktif (27,67) dan jumlah polong isi (80,9).Pyrite oxidation causes the soil pH drops, thus increasing the solubility of aluminium and iron. Saturated soil culture maintains the water depth and makes the soil below saturated. This study aims to determine the effects of soil water depth and amelioration on soil chemical properties and soybean productivity. The experiment is conducted on acid sulphate soil Banyu Urip, South Sumatera Province, from June until October 2012. The experiment is arranged in a split split plot design with three replications. The main factor is water depth in the furrow consisted of 10 and 20 cm under soil surface. The second factor is ameliorant: without ameliorant, lime and straw ash. The third factors are genotypes: Anjasmoro, Yellow Biloxi, Tanggamus and Lawit. The results show that interaction of water depth and amelioration increase soil pH to 4.67, maintain soil P at 10.70 ppm and increase soil K, Ca and Mg to 1.15, 11.70 and 6.90 me/100 g. The soil Fe decrease to 12.14 ppm, whereas Al and Al saturated decrease to 2.06 ppm and 10.36 percent, respectively. Tanggamus has the highest productivity (2.47 t/ha), supported by higher number of leaves (31.5), branches (4.5 - 5.3), productive nodes (27.67) and filled pods (80.9.)

Differences in productivity were observed in various land units on pineapple plantation in Central Lampung even with the same land and fertilization management. The nature of soil chemical and physical variability were thought to be the cause of these differences. The study was aimed to compare chemical and physical soil properties in land units with different pineapple productivity. Soil samples were taken from 6 units of land with low and 3 units of land with high productivity. The soil chemical properties meazured include available P and K, potential P and K, total N, pH, organic C, exchangeable cations, and available micro nutrients. The soil physical properties determined include bulk density, soil texture, and penetration resistance. The data was analyzed using T-test and correlation. The T-test revealed that the high productivity soils were significantly lower in available P, potential P, total N, and available Zn compared to the productivity soils. Furthermore, the high productivity soils were significantly lower in bulk density and penetration resistances both vertically and horizontally. There were significantly negative correlations between pineapple yields with potential P, available Zn, bulk density, and penetration resistance both vertically and horizontally. Overall analyses indicating that the physical properties were more as productivity determinant, particularly bulk density and penetration resistance, compared to the chemical properties. The chemical properties were more as residual conditions after nutrient absorption process to support pineapple productivity. In order to increase the productivity, it is necessary to manage the soil to lower bulk density and penetration resistance. Keywords: Crop management, nutrient management, penetration
