Magnetic properties and magnetic minerals morphology of orchards soils Batu Malang

Apples Plantation is one of the national agricultural assets, especially fruits commodities. This study examined magnetic properties, especially magnetic susceptibility and morphology of magnetic minerals in orchards soils Batu Malang. The magnetic susceptibility test was conducted using Bartington MS2B and magnetic minerals morphology performed by SEM-EDX test. The results showed that the orchards soils magnetic susceptibility has a range of 2.58 – 8.26 × 10^_6m³kg"¹. The results of SEM-EDX test, indicate that magnetic minerals of orchards soils Batu Malang has octahedral shape, that may this magnetic mineral comes from pedogenic processes with various size is 40.64 – 143.07 μm. Some magnetic minerals are spherules that indicate the magnetic minerals come from anthropogenic processes with various size is 34.38 - 67.02 μm. (paper)
