“…The preliminary survey in Probolinggo Regency, a regency in the province of East Java, Indonesia, discovered intensifying use of chemical fertilizers and pesticides yet a declining trend in yield production. Soil quality studies had been performed in a number of areas in Indonesia, among them are of apple plantations [36], cassava fields [37,38], paddy fields [39,40] and post-paddy fields [41], oil palm plantations [2, [42][43][44][45][46], rubber [47], sugarcane [48][49][50], even volcanic soils [51] and drylands [52][53][54]. A few researchers had also compared different fields at once in Bengkulu [55] and West Java [56].…”

Soil is paramount to sustaining living in biomass production, water quality control, climatic mitigation, and biodiversity endurance. Closely associated with sustainable agriculture, it degrades soil in the long run, robbing the soil of its production capacity and food-generating ability. In Probolinggo, a regency in Indonesia, intensifying the use of chemical fertilizers and pesticides yet a declining trend in yield production was discovered. This research analyzed the acid, nitrogen, organic carbon, and nutrients focusing on phosphor, potassium, iron, and manganese contents. Organic carbon/nitrogen ratio, soil organic compound rate, and cation exchange capacity were also discussed in order to illustrate the correlations among chemical substances and their roles in soil and plant maintenance. While such a study has yet to be performed in Probolinggo, the results should show the degree of land deterioration and future attempts at damage control and correction open to facilitate. Employing a simple random method, soil and plant samples were collected from 18 villages in six districts and their chemical contents were compared to the standard set in Government Regulations No 150/2000. The results showed low N-total, P-Bray, P-Olsen, K, C-Organic, and C/N ratio availabilities at 0.18, 13.88, 14.41, 0.37, 1.36, and 7.38 respectively, contrasted to high rates on pH (5.94), Fe (153.46 mg kg–1) and Mn (37.96 mg kg–1). Biomass production is conclusively imperative to fix the land composition and meet the plant nutrient requirements through an organic approach; fertilizers from digester biogas are therefore recommended. This action requires field agricultural advisors to raise awareness of sustainable agriculture.

Volcanic slope soils in Indonesia may have degradation due to forest conversion to intensive agriculture since more than three decades. This research aimed to assess soil characteristics from different land uses and slopes in volcanic slope soil, East Java. Three different land uses, namely crops, apple orchard and forest were chosen as different land-use factors, where each land-use was examined in four slope classes (e.g. 0-8 %, 8-15 %, 15-25 %, and > 25 %), except forest with three slopes area, and each plot repeated three times. Soil samples were taken from three sub-plots at 0-10, 10-30, and 30-50 cm. Variables measured included soil texture, bulk density, pH, CEC, and soil nutrients. Degradation soil quality under horticulture practices (i.e. crops and apple orchard) is shown by the increases of 27-40% soil bulk density and decreases of 17-65% soil nutrient content (i.e. C, N) as compared to forest. The impact of slope on soil fertility degradation was more pronounced in the forest soil as compared to horticulture land. Our study suggested the benefit of tree density and diversity in the forest to maintain soil fertility, and proper soil conservation in the horticultural lands to slow down volcanic slope soil degradation.
