  10. DESKRIPSI HORISON : WARNA TANAH • Warna Matrix – hue, value danchroma, kondisikeringdanlembab, menurutMunsellSoil Color Charts, atau Revised Standard Soil Color Charts • Becak-becak = Mottling– Banyaknya, Ukurannya, Kontras, Batas-batas, danwarnanya (keringdanlembab) Sumber: Soil Profile Description. Otto Spaargaren. ISRIC-World Soil Information. Wageningen The Netherlands

  11. DESKRIPSI HORISON TANAH: KOMPONEN PRIMER • Teksturtanah: – sand (Pasir), loamy sand, sandy loam, loam (Lempung), silt loam, silt (Debu), silty clay loam, silty clay, clay loam, sandy clay loam, sandy clay, clay (Liat) • FragmenBatuan– Kerikil = gravel, Batu-batu = stones, Batubesar = boulders Sumber: Soil Profile Description. Otto Spaargaren. ISRIC-World Soil Information. Wageningen The Netherlands

  12. DESKRIPSI HORISON TANAH: ORGANISASI KOMPONEN PRIMER • Struktur Tanah– grade, ukurandantipe • Tipestruktur: single grain, massive, granular, prismatic, columnar, angular blocky, subangular blocky, platy, rock structure, strukturberstrata • Konsistensi– KondisiKering, LembabdanBasah Sumber: Soil Profile Description. Otto Spaargaren. ISRIC-World Soil Information. Wageningen The Netherlands

  13. DESKRIPSI HORISON TANAH: RONGGA - POROSITAS Pori, termasuksemuaronggadalamtanah, dideskripsikandengan parameter: • Tipe • Ukuran • Kelimpahan • Kontinyuitas • Orientasi. Sumber: Soil Profile Description. Otto Spaargaren. ISRIC-World Soil Information. Wageningen The Netherlands

  14. DESKRIPSI HORISON TANAH: KONSENTRASI • Cutanic features – clay, humus, pressure faces, slickensides, iron coatings • Cementation dancompaction – kontinyuitas, struktur, sifat, derajat • Nodul Mineral – abundance, kind, size, shape, hardness, nature, colour Sumber: Soil Profile Description. Otto Spaargaren. ISRIC-World Soil Information. Wageningen The Netherlands

  15. DESKRIPSI HORISON TANAH: AKTIVITAS BIOLOGIS • Roots – kelimpahandanukurannya • Biological features – Kelimpahandanmacamnya Sumber: Soil Profile Description. Otto Spaargaren. ISRIC-World Soil Information. Wageningen The Netherlands

  16. DESKRIPSI HORISON TANAH: REAKSI TANAH • Adanya carbonate– non-calcareous, slightly calcareous, moderately calcareous, strongly calcareous and extremely calcareous (ujidengan 10% HCl) • pHdilapangan– Hellige test, pH-meter, ujiNaFuntuktanahvulkanik Sumber: Soil Profile Description. Otto Spaargaren. ISRIC-World Soil Information. Wageningen The Netherlands

  17. DESKRIPSI HORISON TANAH: SAMPLE Adaduametodepengambilansampeltanah: • Sampling denganproporsi yang samauntuksemuahorison • Sampling in equal proportions within a depth of 20cm, either from the centre of the horizon, or at balanced intervals if the horizon exceeds 50cm thickness Sumber: Soil Profile Description.
