The Kali Kungkuk micro watershed which is located in the upper area of Brantas watershed, had Â experienced forest conversion to horticulture during the last fourth decades. Since the physiographic of Kali Kungkuk micro watershed is hilly, forest conversion to horticulture may result in soil nutrient stock changes. The research aimed to analyze soil nutrient stock from forest to horticulture land uses (i.e. apple orchard and vegetables) in the Kali Kungkuk micro watershed. The field research was conducted on three different land uses (i.e. vegetable land (PK), apple orchard (PA), and forest (PH)) and four land slope classes (i.e. slope 0-8% (K1), 8-15% (K2), 15-25% (K3), and > 25% (K4)), with three, replicates plots of each. Soil samples were collected at three different depths (0-10, 10-30, and 30- 50 cm) from each plot. The parameters measured included soil texture, bulk density, standing litter mass, canopy cover, basal area, soil organic carbon and total Â nitrogen. Data analysis was conducted with Linear Mixed Effect Models with a level of 5% and a further analysis of LSD test level of 5% as well as a correlation test between observational parameters. The results showed that differences in land use and slope affected to significant differences in the content of soil organic C and total N. In general, forests had higher soil C and N stocks as compared to other land uses (i.e. apple orchard and vegetables). Furthermore, soil organic C and total N was higher in the low slopes (i.e. 0-8%) and (8-15%) as compared to the high slopes (i.e. 15-25%) and (> 25%). The study found a positive correlation between soil nutrient stocks (i.e. C and N) and clay content. In contrast, soil C and N stock was negatively correlated with soil bulk density. Soil fertility degradation that occurs in the Kali Kungkuk micro watershed (i.e. apple orchard and vegetables) requires serious attention in soil management in order to ensure the sustainability of apple and vegetable production.

Differences in tree age and cropping systems may influence the microbial diversity, including fungal species and population. The purpose of this study was to determine the diversity, of species and population of arbuscular mycorrhiza spores and the relationship between the number of arbuscular mycorrhiza spores and the soil chemical properties in different pine age group and coffee as an intercropping system at sloped areas. The study was conducted from April to July 2017. The study used a survey method with 5 age groups (KU) and three replications. The study was divided into 3 stages: 1). collection of soil and root samples, as well as measuring plot characteristics (i.e. basal area, canopy cover, standing litter mass); 2). Measurement of Mycorrhizal in the laboratory (spore extraction, spore identification, root colony percentage analysis); 3). Soil Chemical Analysis (pH, total P, available P). All data was tabulated, and tested using ANOVA with Randomized Block Design. If there is a significantly different, a further LSD test is performed with a level of 5%. Correlation and regression tests were performed to determine the relationship between parameters. The results showed that there were significant differences in the parameters of canopy density, number of genus spores of Acaulospora 100 g-1 soil, Soil pH, and total P in the soil. However, the study was unable to detect significant differences in, other parameters, such as root infection, number population of Glomus and Gigaspore, available P, etc.. The correlation test showed that the increase in the age group of the coffee intercropping system did not correlate with the number of arbuscular mycorrhizae in each plot observed. The number of Arbuscular Mycorrhizal Spores in each age group of intercropping pine did not correlate with the soil's chemical properties (pH, P-Total, P-Available).

Fire is a serious problem that must be faced in the management of forest or plantation areas. Land fires have caused huge losses of soil nutrient. Lampung is one of the provinces in Indonesia having a problem related to land fires. The purpose of this study was to analyze the impact of land fires on the soil base cations (K, Mg, Ca, Na) and cation exchange capacity (CEC) in three different planting zones (i.e. fertilization, harvesting path, and frond stack areas) within oil palm plantations between land with low fire intensity and land with high fire intensity. Observations were made using a survey method in three zones of oil palm plantations, including fertilization area, harvesting path, and frond stack area. Soil samples were collected by using a soil drill at two depths, namely 0-10 cm and 10-30 cm from the soil surface. The study showed that at depth 0-10 cm, land A (land with low fire intensity) had higher K, Na, and Ca contents, as well as higher CEC as compared to land B (land with high fire intensity). At depth 10-30 cm, field A had higher K and CEC content, and lower Mg content than land B. comparing among different zones of oil palm plantations also showed that soil exchangeable K and Mg were significantly different, especially at depths of 10-30 cm. This was due to differences in land management (i.e. fertilization and liming).

Peat land has an important role, function, and benefit for human life, biodiversity, and global climate. The peat swamp forest in Central Kalimantan was devastated to a very large extent, which addresses the restoration of peat swamp forests, has changed the characteristics of peat which contain physical, chemical, and biological characteristics. Peat recovery efforts carried out at the KHDTK Tumbang Nusa consist of natural succession and revegetation. The study aimed to analyze the chemical properties of peat soils in different types of post-fire forest protection and to assess the spatial variability of peat chemical properties in Forest Areas for Special Purposes (KHDTK) Tumbang Nusa, Desa Tumbang Nusa, Jabiren Raya District, Pulang Pisau Regency. The research plot consisted of forest restoration efforts, namely secondary forest, revegetation, and natural regeneration. Variable measured consisted of pH, total organic C, CEC, N, P, K, exchangeable K, Na, Ca, Mg, as well as ash content and water content. The results showed that secondary forest treatment was the best peat swamp forest restoration technique. Spatial variability sub-plots and sample points did not significantly affect the differences in chemical properties of the peat, but the differences in chemical properties of peat is the peat swamp forest was determined by restoration technique.

Peatlands have specific characteristics, namely irreversible drying, so that become flammable. Peat fires have an impact on changes in soil pH. The study aimed to analyze the soil acidity after peatland fires in oil palm plantation. This study used a survey method on two main plots (low and high fire intensity). Samples were taken at two soil depth including 0-10 cm and 11-30 cm in three zones (fertilization area, harvest path and frond pile zone) and repeated three times. Data were analyzed by ANOVA using the 5% nested test, then LSD test, and analyzed for correlation. The results showed that the soil pH on all land was included in the very acid category. Soil pH in the land B (land with high fire intensity) is higher than those in the land A (land with low fire intensity), both in top soil and sub soil. The micro-nutrient elements of Fe and Al in the land B are lower than land A, while the micro-nutrients of Mn in land B are higher than land A. The correlation of soil pH towards Fe and Al is negative, while for Mn is positive (pH increases, acid cations of Fe and Al will decrease while acid cations of Mn will increase). This was presumably due to competition in occupying the land-catchment complex.

Entisol of Wajak Malang has low base saturation and organic matter and slightly acid. The result of the analysis also showed that soil has nutrient P with high criteria; however, N, K, Ca, Mg, Na contents are low to very low criteria. Application of humic acid at the first planting can leave residual nutrients and can still be used in the second planting. Besides urea-humic, goat manure can also be because it can improve soil properties, organic matter and nutrients contents. The purpose of this study was to explore the effect of the application of urea-humic residue with goat manure on the availability of phosphorus, potassium and the growth of okra on an Entisol of Wajak Malang. The combination of treatments consisted of: U1 (soil residue urea-humic 100% + goat manure), UH1 (soil residue of urea-humic 75% + goat manure), UH2 (soil residue of urea-humic 100% + goat manure), UH3 (soil residue of urea-humic 125% + goat manure), UH4 (soil residue if urea-humic 150% + goat manure). The five treatments were arranged in a completely randomized design with three replicates. The results showed that urea-humic residue with application goat manure had no significant effect on available P, exchangeable K in the soil, plants height and leaf number of okra on 4, 6 and 8 weeks after planting.

Agricultural practices, especially land clearing by burning in peat-land, usually causes land-fire and result in nutrient degradation of peat-land. The research was aimed to assess nutrient content (i.e. C, N, P) in oil palm plantation within peatlands post land fire. The study was conducted on Tulang Bawang regency, Lampung Province. Soil samples were collected from two locations with different intensity of land fire, i.e. field with low intensity of land fire (land A) and land with high intensity of land fire (land B). In each land, the soil was taken from two depths (i.e. 0-10 cm and 10-30 cm) in three different zones of oil palm plantation, named as fertilization area, frond stack, and harvested path, with three replications of each. The variable measured including soil organic C, total N, and available P. Prior to statistical analysis, the data were tested normality. The result showed that the location with low intensity of land fire (land A) had higher soil organic C, total N, and available P at 0-10 cm and 10-30 cm depths of soil as compared to the area with high land fire intensity (land B). Application of N fertilizer and liming resulted in a higher total N at 0-10 cm depth of soil and available P (in the land A) in fertilization area as compared to frond stack and harvest path areas, both in land A and land B. Available P in land B at 0-10 cm and 10-30 cm soil depth in the fertilization area was lower than harvest path and frond stack areas, and this was probably due to the high losses through leaching and/or uptake by palm oil.

Orange is a national superior commodity that has an important role in increasing foreign exchange for the country. However, the development of citrus cultivation in Indonesia is still relatively low, probably due to soil fertility degradation. Therefore, this study aimed to analyze the effect of differences in the application of organic fertilizer (form and dose) and their interaction on soil chemical properties, nutrient concentration in the leaf (i.e. N, P, K), and growth in Siamese citrus seedlings. The treatments included the application of a combination of forms and doses of organic fertilizer, namely SD1 (powder dose 2 t ha-1), SD2 (powder dose 4 t ha-1), SD3 (powder dose 6 t ha-1), SD4 (powder dose 8 t ha-1), SD5 (powder dose 10 t/ha), GD1 (granule dose 2 t ha-1), GD2 (granule dose 4 t ha-1), GD3 (granule dose 6 t/ha), GD4 (granule dose 8 t ha-1) and GD5 (granule dose 10 t ha-1). The results showed that there was a significant difference in the interaction between form and dose of organic fertilizer only in the number of primary branches at 4 WAP (weeks after application) with the highest values was found in powder organic fertilizer at a dose of 8 t ha-1 and granules organic fertilizer at a dose 10 t ha-1. In addition, the application of powder organic fertilizer application had a higher plant height at 10-12 WAP as compared to the application of granule organic fertilizer.
