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.

The concept of eco-culture has a sustainability paradigm that emphasizes the harmony of humans and ecosystems. The target is the strengthening of local characters through the study of local genius, as well as the application of science and technological innovation in managing the potential for improving the quality of the environment and humans. Increasing the economy through tourism is its added value. Kampung Baran has a unique ethnographic and geographical setting inhabited mostly by low-income people. The potential that can be developed is agriculture which is now slowly starting to be abandoned. This study examines the application of the eco-culture concept which consists of an image of space, an image of building, and an idealized concept of place for the development of Kampung Baran. Through a descriptive-phenomenological study, the researcher explores the physical-spatial-architectural and economic-social-cultural phenomena of Kampung Baran as the object of study. Furthermore, the study of the application of the concept of eco-culture in the village of Baran was carried out through a SWOT analysis. The results obtained indicate that the concept of eco-culture can be applied in Kampung Baran by emphasizing on strengthening the noble values of the culture of agrarian communities in the expression of tangible and intangible heritage that is adaptive to cultural dynamics and strengthening and developing local potential.

Leaves of Reutealis trisperma (locally known as kemiri Sunan) are potential sources of organic matter and improve soil fertility, especially by increasing soil nutrient availability. This study aimed to analyze the impact of the application of compost using kemiri Sunan leaves as raw material on soil fertility, such as pH, total N and soil organic C. This study used a completely randomized design with six treatments and four replications. The treatments were without compost (control), compost 4 t ha-1, compost 8 t ha-1, compost 12 t ha-1, compost 16 t ha-1 and compost 20 t ha-1. This study used a PVC pipe with a diameter of 14 cm and a height of 60 cm for the composting process and using polybags for the soil incubation process. The leaves were mixed with EM4, molasses, and water in a ratio of 1:1:50; after mixing, all the ingredients were put into a tube, and observations were made. The soil was then mixed with compost according to the treatment dose of compost 0; 4; 8; 12; 16; 20 t ha-1, then added water until it reached field capacity and then put into a polybag and incubated for 30 days. Observations were made at 0, 15, and 30 days after incubation. The results of this study showed that the application of waste compost of kemiri Sunan leaves had a significantly increased soil pH, total N, and organic C. The best application of kemiri Sunan leaf compost was found at a dose of 20 t ha-1 .

Onion has become one of the popular horticulture commodities in Indonesia due to the crop having several benefits. Consequently, the demand for onions in Indonesia increases annually. In contrast, the supply of onion fluctuates because of unstable onion production. One of the factors that affect unstable onion production is soil fertility degradation. Therefore, the study aimed to analyze the effect of different doses of inorganic fertilizer compounds on the chemical properties of soil, plant growth and production. The field research was conducted in the experimental land of the Faculty of Agriculture, Brawijaya University, located in Jatimulyo Village, Lowokwaru District, Malang City. This study could not detect a significant difference in fertilization doses on onion plant growth but could increase the yield and tiller numbers. The highest values of tillers number, tuber fresh weight and tuber dry weight were observed for the treatment of 50% basal fertilizer + 150% compound inorganic fertilizer and the lowest production of biomass, tillers number, wet weight, and tuber dry weight was on treatment control.

The main commodity of food crops cultivated in Indonesia is rice, but rice productivity in Indonesia has decreased. Factors that cause a decrease in rice productivity are land conversion that continues to increase and unbalanced fertilization. Efforts to increase rice yields are by applying a combination of inorganic fertilizers and biological fertilizers. Otherwise, this study focused on studying the effect of the application of a combination of inorganic fertilizers and biological fertilizers on several soil chemical characteristics and rice production in the experimental field of the Faculty of Agriculture, Jatimulyo District, Malang City. Application of biological and inorganic fertilizers with analysys of variance (ANOVA) showed a significant effect on chemical characteristics parameters such as pH and available P. Otherwise, this research showed a significant effect on production, such as the weight of biomass and milled dry grain harvested. Based on this research, the best combination fertilizer is T3 (75% basal inorganic fertilizer + 100% biological fertilizer).

Humic acids play a crucial role in ion exchange and metal ion complexes; therefore, they are potentially useful in improving soil fertility and crop yield. This study aimed to explore the role of humic acid (HA) from various composts in improving degraded soil fertility and maize yield. A field experiment was conducted on Inceptisols having low soil organic carbon, nitrogen and available phosphorus contents. Eight treatments of HA formulas and one control were arranged in a randomized block design with three replications. The HA formulas used were combinations of two doses of HA (0.15 and 0.20% of soil on w w-1 base) and four types of HA (HA extracted from bagasse compost, HA extracted from water hyacinth compost, HA extracted from market waste compost, and commercial HA). The results showed that the HA application increased 16-97% of soil organic carbon, total nitrogen, available phosphorus, exchangeable potassium and calcium compared to the control. The formula of commercial HA at 0.15% was the best treatment for inhibiting soil fertility degradation in agricultural land. The best maize yield of 15.13 t ha-1 and starch content of 63.54% was obtained from the application of commercial HA at 0.20%.

The addition of organic fertilizer into soil increased earthworm growth and its activity and, not only for decomposer group but also for soil digger group (ecosystem engineer).Pontoscolex corethrurus is one of ecosystem engineer group create many channel in soil, so that increased soil porosity and infiltration in soil The objective of this research was to study on N leaching in various biopores condition which formed by earthworm`s activity. Various level of soil porosity and nitrate consentration at controlled condition was obtained from application ofÂ mixture of 3 types of litter (coffee, Gliricidia and durian), N-urea fertilizer and soil digger earthworm (Pontoscolex corethrurus) into soil. Â The treatments tested were (1) KO : Control 1 (without worm, N-Organik and N-Anorganik); (2) KCC : Control 2 (added earthworm, without N-Organic and N-inorganic); (3) UREA : (added earthworm + N-inorganic, without N-Organik); (4) KGD : (added earthworm and N-Organic, without N-inorganic); (5) KGDU : (added earthworm + N-inorganic + N-Organic). Each treatment was repeated four times. The biopores formed by earthworm was measuredÂ from the length of soil channelÂ at 1st, 2nd, 4th, 6th and 8th weeks after treatments (WAP). Measurement on earthworm`s growth was conducted with measuring earthworm`s length, diameter, biomass and casting by the end of treatment (8 WAP). Analysis of nitrate in leachete was done at 2nd, 4th, 6th and 8thÂ WAP. Result of this research showed that application of N-anorganic only led to more active earthworm rather (83 %) than application of N-organic resulting longer vertical channel formed by earthworm.Â However, the increasing the length of vertical channel was not followed by increasing of water percolation. Porosity was related to nitrat leached concentration (R2 = 0.36). Total of leaching was not only influenced by porosity but also by another factor like NO3- -available (influence by N source input). Application of N-anorganic increased concentration of leached NO3- (42 %) than application of N-organic (181 mg L-1 concentration of leached NO3-). No significant (p>0.05) correlation between soil porosity and earthworm`s biomass was found.

Forest plays important roles including, ecology, social and economic, for the sustainability of life. UB Forest, as an example, is located at the foot slope of Mt. Arjuna. This study aimed at elucidating exploring soil chemical properties of the UB forest. Five different land uses i.e., protected areas (KL), pine + coffee (PK), pine + annual crop (PS), mahogany + coffee (MK), and mahogany + annual crop (MS) were selected for this study. Each land use was repeated three times. Inside of each plot (20 x 20 m2 size), three sub-plots (5 x 5 m2 size) were prepared randomly for soil and litter sampling. Soil samples were taken from every sub plot, at four different depths (0-10, 10-30, 30-50, 50-100 cm), and then composited for the respective depth. Soil chemical properties (CEC, pH, total N, available P, C, available bases, soil texture, and litter (thickness, dry weight) were measured. The results showed that land uses in UB Forest significant affected total N, and pH, but theyÂ did not affect available P and CEC. The highest CEC was in KL. However, MS and MK tended to have high total, especially in the depth of 50-100cm.
