“…Konkresi Mn berwarna hitam dan konkresi Fe berwarna merah terdapat pada profil P-3, sedangkan pada profil P-1 dan profil P-2 tidak teridentifikasi adanya konkresi. Keragaman konkresi yang ditemukan pada ketiga profil tersebut menunjukkan keragaman kondisi oksidatif-reduktif pada transek lereng (Curmi et al 1994), meskipun secara umum, ketiga profil dapat dikatakan saat ini berada dalam kondisi oksidatif dan berdrainase baik. Kondisi perakaran efektif pada ketiga profil cukup baik karena akar dapat menembus lapisan olah dan tanaman jati yang tumbuh mempunyai tegakan yang baik.…”

Teak (Tectona grandis Linn f.) produce one of the most desirable wood in the world. Nowadays, fast growing teak resulting from genetically engineered teak have been available. This study aims to look at the relationship between land characteristics and soil classification with vegetative growth of "Unggul Nusantara" varieties of teak. The study was conducted in Ciampea, Bogor Regency. Soil properties were analyzed from three profiles, while the vegetative growth of teak was measured from 2.5-3 years old teak planted on those land. The diversity of soil properties on the profiles were function of the difference of soil parent material as well as its position on the slopes. Three soil profiles of P-1, P-2, and P-3, lying from upslope to the downslope, were classified respectively as Typic Paleudalf, very fine, mix, active, isohipertermic; Typic Dystrudept, very fine, mix, active, isohipertermic; and Typic Hapludult, very fine, mix, semi-active, isohipertermic. Soil of the three profiles were capable of supporting the growth of teak varieties of "Unggul Nusantara". The best grown plant was found on the profile P-1 in the upslope, followed by the plant on the profile P-3 in the downslope, and then the plants on land above the P-2 in the middle slope. Nevertheless, the quality of the teak harvest produced in the three profiles can be categorized as low category. Soil with lime sediment parent material that has a high pH and base saturation is able to provide better growth for plants teak varieties of "Unggul Nusantara".

“…The chemical compositions of these granites are given in Table 1. Variations in the substratum lead to saprolites of different mineralogical compositions and clay contents (Curmi et al, 1994). The textures induce changes in drainage conditions of these saprolites.…”

Smectite genesis in two granitic saprolites was studied, using qualitative and quantitative mineralogical methods and high resolution transmission electron microscopy (HRTEM). The primary minerals (plagioclase and mica) give rise to the formation of different kinds of smectites according to the weathering conditions (pH and drainage). Under a relatively basic, drained environment, a neoformed montmorillonite with a spheroidal organization exists in fillings of plagioclase cores. In the same conditions biotites are transformed into beidellites with a quasi-crystal organization. Under hydromorphic conditions, muscovites evolve incompletely towards smectites, whereas biotites lead to a montmorillonite with a tactoid organization.
