Abstract

Soil erosion causes a loss of nutrients in the soil and is evident in the agricultural areas of Batu City, primarily due to the steep or very steep topography. So it will affect the level of production. Determination of the effectiveness of observation was based on four classes of slope: 0-8%, 8-15%, 15-30%, and >30% at various altitudes: <1,100 m, 1,100-1,300 m, 1,300-1,500 m, 1,500-1,700 m, and >1,700 m above sea level 40 observation points. Geostatistical analysis with ArcMap software was conducted to determine the pattern of semivariograms. The results of this study indicated that the slope, altitude, and organic matter affect the yield of potatoes. The resulting formula is y = 11.845 - 0.258x1 + 0.007x2 + 2.454x3, where y is the potato productivity, x1 is slope, x2 is altitude, and x3 is the organic C, with r value is 0.87 and R2 value = 0.74. The highest potential production of potatoes in Bumiaji reached 33.06 t ha-1, and the lowest was only 7.12 t ha-1. Available land planted with potatoes can produceĀ  35,891 t of potato, with average productivity reaching 24.6 t ha-1.

Abstract

Drought is a major challenge in developing the integrated farming system (IFS) in Trenggalek Regency, making it one of the factors contributing to the construction of the Tugu Dam. Additionally, in developing the IFS area, it is necessary to assess soil fertility and land suitability evaluation for food and livestock feed commodities. The research was conducted in Tugu and Karangan Sub-Districts, Trenggalek Regency by conducting spatial analysis and soil survey at locations potentially affected by dam construction and soil samples analysis at the laboratory. The results of this study found that the level of soil fertility at the research site was included in the low to very low class with characteristics of acidic pH, very low C-organic, very low total N and low base saturation. While the results of the actual land suitability evaluation of rice, maize, and elephant grass showed the land suitability class S3 with limiting factors of C-organic, pH, total N, P2O5, and base saturation.
