Kebakaran di hutan gambut telah mengubah karakteristik lahan tersebut. Ironisnya, saat ini perhatian berupa riset terhadap sifat fisik dan kimia lahan gambut yang mengalami perubahan tersebut masih sangat rendah. Padahal sifat fisik dan kimia gambut merupakan faktor penting yang mempengaruhi kemampuan tanah untuk berproses. Sehingga tujuan dari penelitian ini adalah untuk kondisi fisik dan kimia tanah pada lahan gambut pasca kebakaran tahun 2006 dan 2015. Studi ini dilakukan pada tahun 2017 di Kebun Konservasi Plasma Nutfah, Indonesia dan analisis dilakukan di Laboratorium Ilmu Tanah, Universitas Sriwijaya dan Balai Riset Standarisasi Industri Palembang (Baristand). Berdasarkan analisis uji lanjutan Beda Nyata Jujur (BNJ) pada sifat fisika tanah menunjukkan bahwa ada perbedaan nyata terhadap perubahan kadar air dan bulk density di lahan pasca terbakar tahun 2015 dan lahan pasca terbakar tahun 2006 yang sudah dilakukan kegiatan rehabilitasi. Pada sifat kimia, pH, C-Organik, Phospor, dan Kalium menunjukkan adanya perubahan nyata terhadap kebakaran di lahan gambut pasca terbakar tahun 2006 dan di lahan gambut pasca terbakar tahun 2015, akan tetapi terhadap N-total adanya perubahan akan tetapi tidak terlalu nyata di kedua lokasi. Masih dibutuhkan informasi lebih komprehensif terhadap unsur fisika dan kimia lainnya serta  sifat biologi tanah sehingga dapat menjadi acuan yang lebih presisi. Fires in peat forests have changed the characteristics of the land. Ironically, current attention includes research on the physical and chemical properties of peatlands that have changed is still scarce. Though the physical and chemical properties of peatlands is an essential factor affecting the ability of the soil to process. So, the purpose of this research is to analyze the physical and chemical properties of soil on peatlands after burning in 2006 and 2015. This study was conducted in 2017 at the Kebun Konservasi Plasma Nutfah (Germplasm Conservation Garden), Indonesia and analysis were carried out at the Soil Science Laboratory, Sriwijaya University and the Palembang Industrial Standardization Research Center (Baristand). Based on further analysis of Honest Significant Difference (BNJ) on the physical properties of soil shows that there are significant differences in changes of water content and bulk density in post-burnt land in 2015 and post-burnt land in 2006 that have been carried out rehabilitation activities. In the analysis of chemical properties consisting of analysis of pH, C-Organic, Phosphor, and Potassium showed a real change in fires in peatlands after burning in 2006 and peatlands after burning in 2015. However, at the N-total values, changes occurred but not too real in both locations. More comprehensive information is still needed on other physical and chemical elements as well as soil biological characteristics so that they can become more precise references.

Recently most farmers in developing country like Nigeria has resulted to the use of solid wastes as compost to replenish the deteriorated soils while some are farming on the abandoned waste dumpsite due to their richness in organic matter. This study assessed the soil nutrient and fertility status by investigating the influence of wastes (if any) on physical and chemical properties of soils in and around Lapite dumpsite for environmental sustainability. Ten soil samples each collected from three locations: dumpsite, downslope and upslope sites at depth of 0-20cm were analyzed for soil texture, bulk density, porosity, electrical conductivity, pH, organic carbon, organic matter content (OMC), total nitrogen (TN), available phosphorus (AP), Na, K, Ca, Mg, Fe, Zn, Cu, Pb and Ni. Significant differences were observed on soil physical: moisture content (18.05-38.11 %); Bulk density (1.01-1.54 g/cm3); porosity (49.09-74.56 %) and chemical properties: : OMC (1.39-5.98 %);TN (0.58-1.60 %); AP(0.35-1.09 %) among others in soils from the studied location sites at p ≤ 0.05; however, no remarkable impact was noticed on soil texture. This study has shown that deposition of wastes has impacted the physical and chemical properties by improving soil organic matter contents and increasing nutrient contents such as exchangeable bases and micronutrient, thus enhancing soil organic matter, fertility and productivity status of the soil for maximum plant growth. However, increase in heavy metal concentrations in dumpsite soils call for incessant assessment and monitoring, thus sorting, reuse and recycling should be encouraged to reduce the metal loads over time.

The organic matter content has significantly decreased in some of the tea gardens in north of Iran, thereforeresulting in degradation of their physical and chemical properties. An experiment was conducted in two tea gardens in order to investigate the effect of lime and vermicompost on soil's physical and chemical properties. The studied tea soils were located in Gilan province (Bazkiyagorab and Azbaram) in Iran (with clay loam and sandy loam texture). Vermicompost was applied in 3 levels of 0, 2.5% and 5% and lime was applied in two levels of 0 and 0.5%. The measurements were carried out three times (after 0, 90 and 180 days). The results showed that lime and vermicompost application has significantly affected the calcium carbonate content, pH, the electrical conductivity (EC) and the soil organic matter (SOM) content in the studied soils. Lime application significantly increased the infiltration rate (P<0.01). Comparison of the average interaction of lime with vermicompost in the Azbaram station soil showed that 5% vermicompost and 0.5% lime with an average of 5.49 (mm h-1) had the highest infiltration rate (IR) and had a significant difference with the other treatments. Comparison of the average interaction of lime with vermicompost in Basquegorob garden showed that the treatment of 5% vermicompost with 0.5% lime, the time stage of 180 days with an average density of 1.11 (g cm-3) had the lowest bulk density (BD) and was significantly different from other levels. It seems that the simultaneous presence of lime and vermicompost and their effect on improving the soil structure and increasing porosity, leads to reduction of the soil's bulk density. The results obtained in this study have clearly indicated that the simultaneous applications of vermicompost and lime is an effective way to improve soil physical and chemical properties. However, the real potential of the amendments used in this experiment should be further assessed under field conditions using a test crop.

Organic farming is one of the management strategies that improve productivity of marginal uplands. The study aimed to: (1) evaluate effects of various organic-based fertilizers on the growth and yield of corn; (2) determine the appropriate combination for optimum yield; and (3) assess changes on the soil physical and chemical properties. Experiment was laid out in Randomized Complete Block Design, with 3 replications and 7 treatments, namely; T0=(0-0-0); T1=1t ha-1 Evans + 45-30-30kg N, P2O5, K2O ha-1; T2=t ha-1 Wellgrow + 45-30-30kg N, P2O5, K2O ha-1; T3=15t ha-1 chicken dung; T4=10t ha-1 chicken dung + 45-30-30kg N, P2O5, K2O ha-1; T5=15t ha-1 Vermicast; and T6=10t ha-1 Vermicast + 45-30-30kg N, P2O5, K2O ha-1. Application of organic-based fertilizers with or without inorganic fertilizers promoted growth of corn than the control. But due to high infestation of corn silk beetle(Monolepta bifasciata Horns), its grain yield was greatly affected. In the second cropping, except for Evans, any of these fertilizers applied alone or combined with 45-30-30kg N, P2O5, K2O ha-1 appeared appropriate in increasing corn earyield. Soil physical and chemical properties changed with addition of organic fertilizers. While bulk density decreased irrespective of treatments, pH, total N, available P and exchangeable K generally increased more with chicken dung application.
