Acid upland smectitic soil is identified by high amount of exchangeable Al due to the weathering of aluminum (Al) octahedral layer by H+ saturation and by very low phosphorus (P) status. Calcium carbonate (CaCO3) and calcium silicate (CaSiO3) were commonly used to decrease exchangeable Al and increase soil pH. Laboratory experiments were conducted with clayey smectitic Typic Paleudults from Gajrug region, West Java. The CaCO3 and CaSiO3 were added at rates to replace 0, 1.5 or 3 times of exchangeable Al. After one month of incubation, P sorption kinetic experiments were conducted. The changes in some chemical properties after one month incubation showed that both CaCO3 and CaSiO3 increased the soil pH, exchangeable Ca, and base saturation but did not increase the cation exchange capacity. The results of the experiment showed that both CaCO3 and CaSiO3 decreased the rate constant value of first order kinetic equation (k) and the P sorbed maximum (a) at given amount of added P compared to Control.The CaCO3 was better than CaSiO3 in decreasing k values and on the contrary for a values. The decrease in P maximum sorption and the rate constant of the soil amended with CaSiO3 and CaCO3 due to occupation of P sorption sites by silicates and hydroxyl ions. The CaCO3with the rate to replace 1.5 x exchangeable Al was recommended to decrease the rate constant of P sorption. However, the CaSiO3 at the rate to replace 3 x exchangeable Al was recommended to decrease the maximum P sorption.

Andisol tersebar luas di Indonesia dengan luas total mencapai 5.4 juta ha. Tanah-tanah ini digunakan secara luas oleh petani sebagian besar untuk pertanian hortikultura dan perkebunan teh, dan sebagian kecil untuk peternakan. Karakteristik pola pelepasan anion nitrat sangat spesifik lokasi sehingga perlu diteliti lebih jauh sifat-sifat kimia tanah apa saja yang berpengaruh terhadap pola pelepasan nitrat pada Andisol di Jawa Barat dan Jawa Tengah. Tujuan dari penelitian ini adalah: (i) mengkarakterisasi sifat kimia Andisol, (ii) mengkarakterisasi pola pelepasan nitrat pada Andisol dengan sifat kimia yang berbeda, (iii) mendapatkan hubungan antara sifat-sifat kimia tanah dengan pola pelepasan nitrat pada Andisol di Jawa Barat dan Jawa Tengah. Percobaan pelepasan nitrat dilakukan dengan metode inkubasi. Jumlah nitrat yang terlepaskan dalam penelitian ini disimulasikan dengan menggunakan persamaan first order kinetic. Berdasarkan hasil analisis, sifat-sifat kimia tanah Andisol di Jawa Barat dan Jawa Tengah bervariasi. Pelepasan nitrat pada Andisol Lembang, Pangalengan, Sukamantri, dan Dieng secara umum semakin menurun dengan meningkatnya kedalaman tanah pada satu profil tanah dan semakin meningkat dengan meningkatnya waktu inkubasi. Hasil uji korelasi sederhana menunjukkan bahwa untuk nitrat maksimum yang dapat dilepaskan (N0) memiliki korelasi yang tidak nyata dengan sifat-sifat kimia tanah yang dianalisis. Hal ini menunjukkan bahwa nitrat sangat mobil di dalam tanah. Walaupun demikian N0 berkorelasi positif dengan C organik, N total, Fe-oksalat (Feo), Al-dithionite dan Fe-dithionite. Sebaliknya N0 berkorelasi negatif dengan Al-oksalat (Alo), dan Alo + ½ Feo. Untuk konstanta kecepatan pelepasan nitrat (k) berkorelasi negatif dengan semua sifat tanah tersebut kecuali dengan dengan Fe-dithionite yang mempunyai korelasi positif. Hasil ini menyimpulkan bahwa pelepasan nitrat pada Andisol punya kemungkinan meningkat dengan meningkatnya kadar C organik dan N total tanah akan tetapi menurun dengan meningkatnya Alo + ½ Feo. Alo + ½ Feo juga mempunyai kemungkinan menurunkan kecepatan pelepasan nitrat pada Andisol.

Perubahan Sifat Kimia dan Pola Pelepasan Amonium dan Nitrat pada Ultisol Darmaga yang Diberi Pupuk Pelet Berbahan Dasar Lumpur Kolam Ikan: Chemical Properties Changes and Releasing Pattern of Ammonium and Nitrate on Ultisol Darmaga Fertilized by Fishpond Sediment-Based Pellet Fertilizer Arief Hartono; Lilik Tri Indriyati; Putri Tria Santari; Neng Elin Novianti

Fishpond sediment-based pellet fertilizer enriched with fishpond water and goat manure was made to decrease load of nitrate contamination in water bodies. The objective of this research was to evaluate the changes of some soil chemical properties and the releasing pattern of nitrogen (N)-ammonium (N-NH4+) and N-nitrate (N-NO3-) in Ultisol Darmaga which was fertilized by pellet fertilizer. The rate of pellet fertilizer which was applied to the soil was 6.10 g of pellets/300 g of soil or equivalent to 40.8 ton of pellets ha-1. This rate was based on the amount of N fertilizer for sweet corn that was 200 kg N ha-1. The pots were incubated in 1 week, 2 weeks, 3 weeks, 4 weeks, 5 weeks, 6 weeks, 7 weeks, 8 weeks, 10 weeks, and 15 weeks at field capacity condition. Soil analyses were conducted after the end of each incubation period. The results showed that in the end of incubation period, the application of pellet fertilizer increased soil pH, organic carbon, cation exchange capacity, exchangeable bases, N-NH4+, and N-NO3- and total available N which is the total amount of N-NH4+, and N-NO3- compared to those of control soil. As for the releasing pattern of N-NH4+ and N-NO3-, in the 1 week to 7 weeks of incubation N-NH4+ was dominant and decreased after that. The decrease of N-NH4+ was followed by the increase of N-NO3-. The N-NO3- was dominant from 8 weeks to 15 weeks of incubation. The results recommended that fishpond sediment-based pellet fertilizer improved the soil properties and provided available N.

Penggunaan pupuk urea dan pupuk kandang yang berlebihan oleh petani menyebabkan terjadinya akumulasi ion nitrat pada tanah pertanian. Pengetahuan tentang kemampuan tanah dalam mengerap nitrat menjadi sangat penting dalam kaitan pergerakan nitrat di dalam profil tanah. Tujuan penelitian ini adalah karakterisasi tanah-tanah pertanian yang mempunyai order Andisol di Pulau Jawa dalam mengerap nitrat dan mengidentifikasi sifat-sifat tanah yang mempengaruhi erapan nitrat. Data erapan nitrat diperoleh dengan menjenuhkan tanah dengan larutan nitrat pada berbagai konsentrasi, setelah sebelumnya tanah dijenuhi dengan ion klorida. Nitrat dalam larutan supernatan ditetapkan menggunakan UV Spectrophotometer dengan panjang gelombang 210 nm dan 275 nm. Kemudian, data dianalisis menggunakan dua persamaan yaitu, persamaan Langmuir dan persamaan Freundlich. Hasil menunjukkan bahwa erapan nitrat dapat disimulasikan paling baik oleh persamaan Freundlich. Nilai konstanta K persamaan Freundlich yang merupakan indeks erapan maksimum berkorelasi positif dengan karbon (C) organik, aluminium yang diekstrak dengan amonium oksalat (Alo), aluminium yang diekstrak dengan dithionite-citrate-bicarbonate (Ald) dan Alo+1/2Feo (sifat Andik). Penelitian ini merekomendasikan bahwa C organik, Alo, Ald dan sifat Andik mengontrol erapan nitrat.

Pupuk urea merupakan sumber hara nitrogen (N) yang paling banyak digunakan di Indonesia, termasuk pada lahan sawah. Urea merupakan pupuk N yang larut air sehingga penggunaan urea di sawah perlu dikaji dalam hubungannya dengan pelepasan pupuk. Di dalam penelitian ini digunakan urea dengan formulasi berbeda yaitu pupuk urea Kujang dan Pupuk Sriwijaya (Pusri) yang merupakan urea konvensional dan urea prill dan granul yang merupakan urea modifikasi yang mengandung formaldehida masing-masing 0.10 dan 0.50%. Tujuan penelitian ini adalah untuk mengevaluasi pelepasan N dari tipe urea konvensional dan urea yang diberi formaldehida pada kondisi tanah tergenang. Metode penelitian yang digunakan adalah inkubasi dan pencucian. Inkubasi dilakukan selama 7, 14, 28, 45, 60, dan 90 hari serta dilakukan pencucian pada setiap akhir masa inkubasi. Hasil pencucian ditetapkan kandungan amonium dan nitrat. Hasil penelitian menunjukkan bahwa pelepasan N dalam bentuk amonium dan nitrat antar perlakuan pupuk urea tidak berbeda nyata. Hasil total N tercuci menunjukkan nilai paling tinggi diperoleh oleh urea granul sebesar 78.0 mg tabung-1, kemudian disusul oleh urea prill 75.2 mg tabung-1, urea kujang sebesar 71.5 mg tabung-1, dan urea pusri sebesar 68.4 mg tabung-1. Berdasarkan hasil persamaan first order kinetic, diperoleh nilai pelepasan maksimum dan konstanta kecepatan. Nilai pelepasan maksimum tertinggi dimiliki oleh urea granul sebesar 94.6 mg tabung-1, kemudian urea prill sebesar 88.3 mg tabung-1, urea Pusri sebesar 82.3 mg tabung-1, dan urea Kujang sebesar 79.2 mg tabung-1. Sementara untuk nilai konstanta kecepatan, konstanta kecepatan tertinggi diperoleh pada urea kujang sebesar 0.0349 hari-1, kemudian dilanjutkan oleh urea prill dan pusri sebesar 0.0256 hari-1, dan urea granul sebesar 0.0253 hari-1. Hasil penelitian menunjukkan bahwa urea yang diperlakukan dengan formaldehida terutama dalam bentuk granul cenderung memiliki kemampuan untuk memperlambat proses pelepasan N yang ditunjukkan dengan nilai konstanta kecepatan pelepasan N yang paling rendah.

Productivity of pepper in Bangka Belitung Province has decreased because one of the causes is the problem of the low nutrient availability. The research was conducted in Bangka Belitung Province to determine the distribution of pH, exchangeable aluminium (Exch Al), and available phosphorus (P) and the correlation among those parameters. Soil samples at depths of 0-30 cm and 30-60 cm were collected at the specified points on a 1: 250,000 scale land system map. The pH was determined by shaking the soil sample with distilled water and the ratio of soil sample and distilled water was 1:5. Exch Al was extracted using 1.00 mol L-1 KCl and determined by titration. Available P was determined using the Bray 1 method. Basic statistic analyses to have minimum, maximum, average and standar deviation (SD) values were conducted. Correlation test among pH, exch Al, and available P to evaluate their relationship were also conducted. The results showed that soils in Bangka Belitung were relatively acid, relatively high exch Al especially in the depth of 0-30 cm and relatively low available P as Bray 1-P. Bray 1-P and exch Al on the depth of 0-30 cm had higher SD than that of the other paramaters. As for correlation analyses, pH significantly negatively correlated with exch Al. pH and exch Al did not correlate with Bray 1-P. This research suggested that soil in Bangka Belitung had problem with soil acidity and low amount of available P in the form of Bray 1-P. The amount of Bray 1-P did not correlate with the amount of exch Al.

The absence of a landfill has increased the illegal waste disposal sites in Malaka Regency, which was established between 2013 and 2021. Therefore, this study aimed to analyze suitable and available land for the development of a landfill. The methodology used consisted of 2 analysis steps, namely land suitability and land availability. Land suitability was analyzed using a multi-criteria decision-making method, which included the slope, stone type/geology, lithology, soil type, soil texture, soil depth, soil drainage, distance from settlements, and water sources. The criteria were then weighted using the Analytical Hierarchy Process (AHP) and geographic information system for overlaying. Furthermore, the results of the land suitability analysis were used to determine its availability with the aid of spatial and regional planning (RTRW), land use, and forest area maps. The results showed that the highly suitable (S1) and available terrain for the landfill in Malaka Regency covered an area of 203.37 ha or 1.73% of the regency. Also, the analysis results indicated that there was still adequate land available for the landfill.

The releasing pattern of applied P in the acid upland soils and the soil properties influencing the pattern were studied. Surface horizons of six acid upland soils from Sumatra, Java and Kalimantan were used in this study. The releasing pattern of applied P (300 mg P kg-1) of these soils were studied by successive resin extraction. P fractionation was conducted to evaluate which fractions released P to the soil solution after successive resin extraction. The cumulative of resin-Pinorganic (Pi) release of soils was fitted to the first order kinetic. Regression analyses using factor scores obtained from the previous principal components analyses was applied to determine soil properties influencing P releasing pattern. The results suggested that the maximum P release was significantly (P < 0.05) increased by acidity plus 1.4 nm mineral-related factor (PC2) i.e. exchangeable Al and 1.4 nm minerals (smectite and vermiculite) and decreased by oxide related factor (PC1) i.e. aluminum (Al) plus 1/2 iron (Fe) (by ammonium oxalate), crystalline Al and Fe oxides, cation exchange capacity, and clay content. P fractionation analysis after successive resin extraction showed that both labile and less labile in the form of NaHCO3-Pi and NaOH-Pi fractions, respectively, can be transformed into resin-Pi when in the most labile resin-Pi is depleted. Most of P released in high oxides soils were from NaOH-Pi fraction while in low oxides soils were from NaHCO3-Pi. P release from the former fraction resulted in the maximum P release lower than that of the latter one. When NaHCO3-Pi was high, NaOH-Pi was relatively more stable than NaHCO3-Pi despite resin-Pi removal. NaHCO3-Pi and NaOH-Pi are very important P fractions in replenishing resin-Pi in these acid upland soils.

Pesticides are widely used in agriculture, including on peat soil. The objective of this study was to analyze the effect of the application of paraquat, difenoconazole, and butylphenyl methylcarbamate (BPMC) on CO2 emissions and concentrations of phenolic acids in a peat soil. Peat soil sample was taken in District of Pulang Pisau, Central Kalimantan. The peat soil was applied with 1.89 mg kg-1 paraquat, 1.72 mg kg-1 difenoconazole and 1.65 mg kg-1 butylphenyl methylcarbamate (BPMC), then the soil was incubated for 1, 2, 4 , 5, 7, 10, 14, 21, 26 and 30 days. The results showed that the application of pesticides on peat soil increased CO2emission, and decreased CH4 emission and phenolic acid concentrations up to 30 days of incubation. The CO2 emmisions were derived from C of degraded pesticides and from C of phenolic acids, although the oxidation reaction was not accompanied by the change of soil pH.

Conventional soil analyses are time-consuming; therefore, the soil quick test (QT) method is needed. This study was to assess the accuracy of soil pH, N-nitrate, available phosphorus (P), and exchangeable potassium (K) analysis determined by the QT method developed by Akvo and calibrated with standard laboratory methods. The field research collected 131 soil samples, collected from horticultural lands in 4 regencies within East Java-Indonesia, started from February to August 2017. Soil analysis measured were soil pH, N-nitrate, available P, exchangeable K, textures, organic C, and CEC. The colorimetric-based QT method was performed on the soil sample extracted by Mehlich 1, and the color was developed by dipping strip test paper in supporting chemical solutions. A smartphone camera was used for the reading, and the results were directly displayed on the smartphone screen. The QT method’s calibration models were created by stepwise multiple linear regression involving the correlated soil chemical properties. The values of calibrated QT method (i.e. soil pH, N-nitrate, and available P) showed significant correlations with the values from the laboratory. However, the results suggested that the QT method developed by Akvo could be used for nitrate due to having a relatively high correlation with that of standard laboratory.
