The study aimed to assess soil biochemical properties and nutrient leaching in palm oil plantation. The research was conducted in smallholder oil palm plantations which were located in Jambi Province - Indonesia. Nutrient leaching was determined by measuring nutrient concentration in soil solution bi-weekly and monthly in the frond stacked and fertilized areas; soil water samples were collected by using suction cup lysimeter. The result showed that the application of mineral fertilizer (e.g. NPK) and dolomite resulted higher base saturation, exchangeable Ca, and available P in the fertilized than frond stacked and inter row areas (p â‰¤ 0.05). Stacking palm oil frond increased the soil macro-porosity, hence decreased leaching of K, Mg, Na, P, and total Al in the frond stacked than in the fertilized areas. The lower leaching losses and the higher soil macroporosity in the frond stacked than in the fertilized areas indicated that either the water did not dilute nutrient in the soil due to bypass flow, or the nutrient release from mineralization did not surpass nutrient demand which is quickly uptaken by palm root. Proper soil management through synchronizing rate of fertilizer application with nutrient output or frequency of fertilizer application may potentially minimize leaching losses.

Differences in land use systems may resulted in different soil cover, litter input, and soil management practices, and consequently affect to soil nutrient stock. The study aimed to assess soil carbon (C) and nitrogen (N) storages on various soil depths from difference land use systems within UB forest. The research was conducted in UB forest, Malang – Indonesia, from April to November 2017. Soil sample was collected from four soil depths (0-0.1, 0.1-0.3, 0.3-0.5, and 0.5-1.0 m) within five land use systems, including (1) protected area; (2) pine + coffee; (3) pine + crops; (4) mahogany + coffee and (5) mahogany + crops, each with three replicate plots. Soil C and N concentrations, soil texture, and bulk density, were measured. The study showed significant difference in soil C and N storages among land use systems. In 0.5 m depth of soil, soil C and N storages was higher in protected area (64% and 53%, respectively) as compared to other land use systems. The result support clay content controls soil C and N stock, whereas vegetation determines soil N stocks. Therefore, proper management in vegetation and soil were needed to conserve soil C and N storages.

Soil degradation is expected to continue as forest conversion into other land uses increases significantly. In Indonesia, Jambi is one of the main areas for the development of oil palm and rubber, whichare mainly converted from the forest. As a base for better management, we attempted to study macro-porosity in rubber and oil palm plantation, in comparison to secondary forests. Four landuse systems (secondary forest, jungle rubber, rubber plantation and oil palm plantations) in Bukit Duabelas, Sarolangun District, Jambi Province, Sumatera, were selected for this study. The number of macropores in vertical or horizontal planes and their related factors (root mass, litter thickness, % organic C, bulk density, water content at pF 0 and pF 2.54, aggregate stability) were measured within the soil profiles. Forest conversion to jungle rubber, rubber and oil palm plantation led to a decrease of macro-porosity in the soil profile, especially in the upper 50 cm. Macropores, both at vertical and horizontal planes in the secondary forest was significantly higher than other landuses. Horizontal macropores in jungle rubber were higher than rubber and oil palm plantation, but not the vertical macropores. Among the soil properties measured, litter thickness, coarse root dry mass (Ø >2 mm), mesopores and aggregate stability were closely associated with soil macro-porosity. However, macro-porosity in the soil profile was insignificantly correlated to soil bulk density and % organic C. Increasing the number of horizontal macropores resulted in higher nutrient leaching, especially K and Na.

Pyroclastic materials from Mount Kelud eruption which deposited in surrounding areas has very low nutrient availability. Fertilizer efficiency is normally low due to a coarse texture. This research was an attempt to increase nutrient availability using zeolite and organic matter in combination with inorganic fertilizers. The materials was treated with three rates of inorganic fertilizers (100%, 70%; 40% of the recommended rates, i.e. Urea 400 kg/ha; SP-36 150 kg/ha, and KCl 75 kg/ha), in combination with three types of amendments (zeolite, Tithonia diversifolia leaves, and cow manure at the rate of 20 t/ha), and 100% inorganic fertilizer treated materials as control, and incubated for 60 days. Soil samples were taken every 10 days after incubation and analysed for soil pH, C-organic, available N, P, K content measurement. The results showed that total N content increased with the rates of inorganic fertilizers. At 10-20 days after incubation the content of NH4+ is greater than NO3- but gradually changed after 30 days after incubation. Apparently, zeolite treated materials had lower NH4+ content than organic treated samples at 10-20 days after incubation, however at 60 days after incubation its NO3- content was relatively higher than Tithonia leaves treated samples. At 60 days after incubation, the higher the fertilizer rates, the higher the content of available P and exchangeable K. The highest content of available P and exchangeable K occurred respectively in cow manure and Tithonia diversifolia leaves treated materials. Until 60 days after incubation, organic treated materials had a higher amount of available and exchangeable K than zeolite treated materials, because they originally contain considerable P and K. However, at 60 days after incubation, zeolite treated materials contained the highest amount of NO3-. This indicated that zeolite had a higher capability to retain mineral N, hindering N removal from leaching and volatilization. A higher nutrient holding capacity could be related to the increasing cation exchange capacity after the addition of amendments, and to a lesser extend to pH and % C.

Market demand for maize (Zea mays L.) in Indonesia is increasing from time to time along with the increasing demand for food and livestock for fodder. However, current farming practices in the upland area where maize usually cultivated, threaten the sustainability of maize production. Conservation farming could be an alternative to reduce land and soil degradation caused by current farming practices. A factorial randomized block designed field experiment was conducted to determine the combined effect of biogeotextile with cover crop residues and soil tillage on growth and yield of maize. The treatments included utilization of Mendong plant’s mat (Fimbrystilis globulosa) as biogeotextile material and four cover crop species: Sunn hemp (Crotalaria juncea), Cowpea (Vigna unguiculata), Pigeon pea (Cajanus cajan), and Mucuna (Mucuna spp). The results showed that the biogeotextile mat and cover crop residues, but not soil tillage, increased maize height and the number of leaves, and yield of maize. Biogeotextile mulch increased maize yield up to 43% compared to control. The highest yield (8.0 t/ha) was shown by the combination of biogeotextile application with cowpea residues. Conservation farming is prospective for improving plant production and protecting land from degradation.

Kajian Perubahan Sifat Fisik dan Kimia Akibat Penyawahan pada Andisol Sukabumi, Jawa Barat Dewo Ringgih; M. Luthfi Rayes; Sri Rahayu Utami

Areal persawahan di Indonesia tersebar hampir 42% lahan sawah ada di Pulau Jawa, 27% di Sumatera, sedangkan 13%, 11%, dan 7% berturut-turut ada di Kalimantan, Sulawesi, dan Bali, NTB dan NTT. Lahan sawah menunjukkan adanya indikasi pelandaian produksi padi yang disebabkan oleh degradasi kesuburan tanah dan perubahan sifat fisik akibat reaksi fisiko kimia tanah sawah. Sesuai dengan sifat tanah asalnya, baik dimanfaatkan untuk lahan kering atau lahan sawah, terdapat perbedaan yang mendasar atas kedua tanah tersebut. Perbedaan tersebut nampak pada sifat morfologi, fisika, dan kimia. Penelitian ini difokuskan pada perubahan-perubahan sifat-sifat tanah antara lain sifat morfologi, fisik maupun kimia pada ordo Andisol di daerah Sukabumi, Jawa Barat. Pada lokasi atau daerah penelitian diamati 6 profil. Masing – masing 3 profil untuk tanah sawah, dan 3 profil untuk tanah bukan sawah (Tegal). Sifat fisik pada ordo Andisol menunjukkan perbedaan yang cukup nyata adalah nilai bobot isi (Bulk Density). Perlakuan pengolahan lahan pada epipedon (kegiatan pembajakan dan pelumpuran) dapat meningkatkan nilai bobot isi tanah. Bobot isi tanah pada lapisan tapak bajak (pada lahan sawah) lebih tinggi dari lapisan tanah di atas maupun dibawahnya. Penyawahan tidak menyebabkan perubahan pH tanah. Perbedaan kandungan C-organik yang di amati, banyak dipengaruhi oleh sedikit banyaknya masukan bahan organik ke dalam tanah. Nilai Kapasitas Tukar Kation (KTK) tanah dipengaruhi kandungan C-organik dan jenis mineral liat pembentuk tanah tersebut. jadi perbedaan nilai KTK antara lahan tegal dengan lahan sawah banyak dipengaruhi oleh banyaknya masukan bahan organik ke dalam tanah, sehingga semakin tinggi nilai C-organiknya maka semakin tinggi pula nilai KTK nya.

Changes in natural land use for monoculture cropping systems may affect the soil properties over a certain period of time. In an attempt to evaluate soil chemical properties in the cassava cropping system, the research was conducted in Pati Regency, Central Java. Four land use systems were compared, i.e. monoculture cassava (cultivated for 5, 10, and 15 years) and agroforestry systems in two different slopes (i.e., 8-15% and 16-40%), with four replications. Soil samples from each location were taken at a depth of 0-20 and 21-40 cm for soil chemical analysis (pH, cation exchange capacity, organic C, total N, available P, exchangeable K, Ca, and Mg). Soils in agroforestry systems had higher pH, CEC, the content of organic C, total N, exchangeable K, Ca and Mg than in cassava cropping systems, especially on the slope of 8-15%. The soil under 15 years cassava and on the slope of 16-40% had the most degraded soil chemical properties, as reflected by the lowest content of organic C, total N, exchangeable K, and slightly lower CEC and the content of exchangeable Ca and Mg. Soil chemical properties on the slopes of 8-15% were significantly better than on the slopes of 16-40%, especially in CEC and the content of organic C, total N, exchangeable K and Mg. However, there was an unclear pattern of the available P content, which was possibly due to the application of P fertilizer in cassava cropping systems.

Landuse change are suspected to be one responsible to soil fertility decline on Slamparejo, Jabung, Malang. Efforts done by local farmers to deal with these problems are plantation of P. falcataria trough a reforestation program around 2003-2004. The benefits of the program are still need to be assessed so that this research was done (1) to compare the soil quality between P. falcataria-planted field and no P.falcataria field by the parameters of soil organic matter content and available N, (2) to study the relationship between organic matter input and soil organic matter content and available N, and (3) to identify factors affecting N availability post-P. falcataria plantation.This research used randomized block design with 5 treatments (annual crop field, 3 and 6 years P. falcaria plantation field, agroforestry field with P. falcataria + coffee + talas plantation, and ex-P. falcataria-planted field. Soil were sampled compositely by 3 replication from 0-20 cm depth. Litter were sampled from a 0.5m2 sub-plot of each treatment.Results showed that P. falcataria plantations enhance soil fertility indicated by increased soil organic matter input to 10.6 times (monoculture) and 17.6 times (agroforestry) control, increased soil organic matter content by 1.5 times (monoculture) and 2.3 times (agroforestry) control, increased total N of 1.6 times (monoculture) and 2.4 times (agroforestry) control, increased ammonium by 1.7 times (monoculture) and 3.2 times (agroforestry) control, and increased nitrate by 2.4 times (monoculture) and 3.9 times (agroforestry) control. The increased soil N content of P. falcataria-planted field were caused by higher soil organic inputs compared to those with no P. falcataria plantation. Nitrogen availability affected by soil texture but have no relationship with soil pH. However, agroforestry fields showed higher pH, organic C, total N, and available N than monoculture P. falcataria fields. Measured soil chemical properties showed no significant change by the increase of P. falcataria age, moreover, they declined down towards control on ex-P. falcataria plantation. This indicates that reforestation would only give a temporary soil quality enhancement.Key words: Regreening, Paraserianthes, Agroforestry, Soil organic matter, nitrogen total

Tailings, waste material from gold processing, contain heavy metals that are toxic such as mercury (Hg). One of the negative impacts is causing contamination of soil, developed through the accumulation of heavy metals. Phytoremediation is an alternative technology, using plant to clean heavy metal contaminated soil. A research, using Caladium bicolor, Paspalum conjugatum and Commelina nudiflora was then conducted as phytoremediation for contaminated soil. The research was conducted in the greenhouse using a randomized block design (RBD) with 3 factors and 3 replications. The first factor was percentage of tailings in the soil (10% and 20%). The second factor was the type of phytoectractor plants (C. bicolor, P. conjugatum and C. nudiflora). The third factor was the use of organic matter (with and without organic matter). The study was conducted in two steps, namely 1) phytoremediation, using C. bicolor, P. conjugatum, and C. nudiflora; 2) evalution of corn growth after phytoremediation. The results showed that Hg content in the soil containing 10% tailings (T1) was twice less than in the soil containing 20% tailings (T2). The addition of organic matter increased the potential for Hg absorption and consequently reduced content of Hg in the soil. C. bicolor, P. conjugatum and C. nudiflora decreased Hg content in the soil, and hence potentially used for phytoremediation. Of the three plants, C. nudiflora showed the highest Hg absorption. Decreasing content of Hg in the soil improved corn growth, as indicated by increasing height, number of leavs and dry weight.Keyword: Mercury (Hg), Hyperacumulator, Phytoremediation

Mount Merapi is most active volcano and periodically erupted. The erupted materials are soil parent materials which rich of base cations that useful for plant growth. Leaching process was used as alternative approach to study base cations released. Leaching experiment used artificial rain water. The effort to reduce base cations leached and also increase base cations relesed was using chicken manure, leucana litters, and Arachis pintoi that used as cover crop as the treatment of experiment. The leaching experiment simulated 4 years rainfall intensity. After incubation for 96 days (4 years rainfall simulation), addition of chicken maure and leucana litters decreased base cations leached in Mount Merapi pyroclastic materials, except for K+ by 16%. Planting Arachis pintoi decrease base cations leached in Mount Merapi pyroclastic materials by 13% but did not increase base cations released.Key words: pyroclastic, leaching, base cations
