Â Effort to reduce the high dependence of farmers on inorganic fertilizers is introducing compost as soil conditioner. The objectives of this research are to create enriched granular-compost (EGC) and to test its effect on nutrient availability, plant growth, and grain yield in intensive farming systems. The research was conducted in two consecutive years (2011-2012), consisting of three steps: production of EGC, incubation and field experiment. Incubation experiment was designed by randomized complete design with 5 treatments (control, 4, 6, 8, and 12 Mg ha-1), and the design of field experiment was randomized block design with 7 treatments (control, inorganic fertilizer (IF), 25% EGC + 75% IF, 50% EGC + 50% IF, 75% EGC + 25% IF, 100% EGC + 100% IF and 100% EGC). The results showed that application of EGC increased total-N and P-available 12.5% and 33% respectively on the 10th day after incubation. The highest grain yield (6.13 Mg ha-1) was gained from the application of 100% EGC + 100% IF. The productivity of rice is closely related to the number of productive panicles per plant (r = 0.507*) and percent of filled grain (r = 0.685*).Â Â Keywords: enriched granular-compost, nutrient availability, grain yield

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.

Degraded lands are getting extensive worldwide. Even its existence has projected as a solution to fulfill agricultural land scarcity to meet the global demands of food and other agricultural goods, the rate of its extension should be inhibited. Some factors play important role. This research was aimed to find the explanation about how degraded land, biophysical and social factors are related. Research site was located in Lekso Watershed, East Java, Indonesia. Land degradation is assessed by evaluation of the critical land status based on procedure established by Indonesia’s Ministry of Forestry in form of Regulation No. P.32/Menhut-II, 2009.A series of field survey using secondary data obtained from GIS tool performed to collect data for quantify the critical land status. Social factors in this study were limited on people perception, awareness and participation. These data collected by in-depth interview to the respondents. Site of presented respondent selected with purposive sampling, while the respondents in each site selected with stratified random sampling method. The research revealed that surface cover demonstrated high correlation and regression toward critical and very critical land (average r = -0.9822, R2= 0.9648). However, slope steepness located in high altitude showed a contrary trend in which increasing slope steepness decreased the number of total moderate, critical and very critical lands. The functional area of this location as protected forest gave a good surface cover on the steep slope and resulted on small area of degraded land. On the other side, negative perception about cultivation on forest and steep slope resulted in positive correlations with the area of very critical land (r = 0.6710 for cultivated forest, and r = 0.9113 for cultivated steep slope). Moreover, people awareness about flood, landslide and drought gave a negative correlation (r = -0.6274) with critical and very critical area. At last, people participation on farmers’ organization could not be used to elucidate the range of degraded land as the participation in this context did not include the competency building about soil and water conservation values.

The utilization of natural resources in recent decades is not accompanied by proper and effective management. This has a major impact on environmental degradation in watershed scale and climate change. The study aimed to evaluate changes in soil characteristics at various ages of sand mining and the cost of reclamation of environmental degradation due to sand mining activities. The study was conducted in Sumberbulu Micro Watershed, which is located in Wajak Sub-District, Malang Regency. Soil sampling was collected from un-mined, 2 to 6 years old sand mining and post-mining lands. Natural resource equivalency analysis (REA) was applied for environmental damage assessment and reclamation cost calculation required to restore natural resource services to their original condition. The findings show that sand mining activities significantly decreased soil organic C in 0-40 cm soil depth, resulting in increased soil bulk density and decreased soil porosity at 20-40 cm depth of soil. Sand mining activities by using truck traffic carrying mining products, soil erosion, and the removal of topsoil during mining activities determined changes in soil properties. REA shows that the total area of land that must be reclaimed is 21,487 ha. The land will be reclaimed by revegetation (with maize) to restore the lost function of environmental services and income of local farmers, assuming a reclamation cost of 36,767,500 IDR/ha. Therefore, post-mining land reclamation should be encouraged by the government for mining business actors in Indonesia so that the land can be reused as before.

This study aimed at determining the community structure and diversity of soil bacteria in several land-use changes as an environmental bioindicator. This research was conducted in areas of intensive agriculture (PI), monoculture abandoned old-coffee plantation (KTT), mixed-young coffee plantation (HLS), and secondary forest/reference site (RS) in UB Forest (UBF) area, Malang, Indonesia. Soil samples were taken as a composite at three different points in each area using a soil ring at a depth of 0-20 cm. The 16S rRNA gene was used to determine the community structure, species richness, diversity, and ecological index (Chao1, Shannon, Simpson, ACE) of soil bacteria using the NGS approach. Statistical data were analysed using R and QIIME software. The community structure of soil bacteria at the phylum level displayed the same pattern in all study sites where Proteobacteria, Acidobacteria, Actinobacteria, Chloroflexi were the dominant groups. Conversely, the bacterial composition showed differences between study sites at the genus level. Alpha diversity in agricultural areas (PI, KTT, and HLS) was higher than forest area (RS), but it was not followed by bacterial beta diversity. The distinct soil bacteria composition and diversity were influenced by the physicochemical of soil properties in the studied area. Therefore, several bacterial taxa suggested being a potential bioindicator of forest soil degradation due to land-use change in this study. Soil bacterial indicators can be utilized to evaluate or monitor alteration of soil quality in terms of forest restoration or rehabilitation.

Nutrient loss in dry land through surface runoff and soil erosion is thought to dominate the watershed eutrophication. Conservation agriculture is expected to be able to reduce the nitrogen (N) loss into river systems. This study aimed to compare the N total input between conservation and conventional farming systems and to analyze N losses through surface runoff and soil erosion in conservation agriculture compared to conventional farming systems. The study was conducted at Agro-Techno-Park at Jatikerto, Brawijaya University from December 2017 to September 2018. The experiment was designed with three factors, i.e. (1) with and without biogeotextile, (2) No and conventional tillage, (3) application of four kinds of cover crop residues, with three replications. Results of the study showed that conservation agriculture was able to provide higher N inputs into the soil than conventional agriculture. The N loss through surface runoff was relatively low, ranging from 0.03 kg/ha to 0.45 kg/ha. N loss through erosion with conventional tillage and without biogeotextile reached 15 kg/ha to 32 kg/ha. No-tillage practices combined with the biogeotextile application significantly reduce N losses through soil erosion to only 0.3 kg/ha to 5 kg/ha. Conservation agriculture is one of the solutions to overcome the trade-off between the need for increased food production and environmental protection.

Degradation of soil functions in storing and cycling nutrients may be related to topography and land-use change. The research aimed to analyze the impact of land-use changes and slope positions on soil function in nutrient stock within Kalikungkuk micro watershed of East Java, Indonesia. Four different land-uses such as vegetable crops, agroforestry, shrub and forest were selected with three slope positions (e.g. ridge, slope, and valley), and three replications of each. Soil samples were collected at 0-10, 10-30, 30-50, and 50-100 cm depth of soil. Variables measured included soil properties (e.g. bulk density, soil texture, pH, CEC, soil nutrients). Slope positions impact on differences in soil physical (i.e. soil bulk density, soil texture) and chemical (i.e. total N, exchangeable K) properties. In addition, forest conversion to other land-uses (i.e. agroforestry, shrub, vegetable crops) decreased soil nutrient concentration (i.e. total C, total N, Ca, Mg, Na), and consequently resulted in degradation of soil nutrient stocks of especially C and N. The strong positive correlation between soil nutrient stock (e.g. C and N) and vegetation cover such as canopy cover, basal area, and litter (r = 0.63 – 0.78, r table 1% = 0.39) showed the benefit of biodiversity in maintaining soil function on the nutrient stock.
