Abstract

Morphology and physiochemical characteristics of three soils within the altitudinal range of 315 to 1490m under different vegetal cover of South Sikkim forests are discussed. The soils are acidic with fairly high content of organic matter and total nitrogen. Exchangeable calcium is maximum at the surface of all the soils and highest under mixed broad-leaved species. Humic acid content decreases down the profile. The properties of the three soils differ fairly widely and the difference can primarily be attributed to differences in physiograpby reflected through differences in vegetal cover and ultimately in the resultant soils. The three soils have been classified upto sub-group level according to Soil Taxonomy.

Abstract

Eight different soils were recognized in South Kheri forests on the basis of diffence in their characteristics. The soils are developed on alluvial sediments and are more or less young with marks of pedogenesis either faint or lacking. Sand constitutes the bulk of the solum invariably with varying amounts of silt and clay in the pedons and manifest their properties accordingly. Grasses appear to be the initial colonizers of the depositional surfaces and with advancement in pedogenesis woodland replaced grasslands in the process or ecological succession. They do not appear to have atained equilibrium with their environments so far and are still in dynamic state.

Abstract

The soils of the grassy blanks, locally known as Chandars of the pilibhit and South Kheri forests were studied to sort out the salient differences in their characteristics in relation to associated vegetation. The growth of the supported vegetation was found to be related to organic matter and clay content. Where texture is comparatively heavier, indicative of high moisture retention capacity, with pronounced translocation of clay resulting into argillic horizon, and availability of nutrients is high, the invasion of grasses by Shorea robusla and Colebrookia oppositifoloa is apparent. The grasses are tbe early colonizers and not the retrograded stage of vegetation. The soils of the sites have heen classified as Typic Ustipsamment,Entic Haplumbrept. Eutric Ustochrepts and Mollic Argiustalf.

Abstract

X-ray diffraction of selected soil clay of South Kheri forests of Uttar Pradesh brings out kaolinite as the dominant silicate mineral, both at the surface as well as the subsurface of all the pedons. In addition, small amounts of goethite, gibbsite and integrated micaceous minerals are also identified in the clay fractions. An occurrence of some vermiculite only in the three pedons under natural sal (Shorea robusta), which decreased at the subsurface, may perhaps be a peculiar coincidence only as no tangible explanation exists.

Abstract

Mineralogical study of the fine sand fraction of ten typical soils of 'South Kheri forests of Uttar Pradesh brings out that quartz is the preponderant detrital mineral in all these alluvial soils followed by mica which is higher in lower depths' especially the muscovite type. The heavy minerals which are present in small quantities' include mainly chlorite' iron-ores and tourmaline' and in very small quantities zircon' sphene' staurolite' apatite' garnet' bornblende' kyanite and epidote. Petrographic examination revealed that excepting quartz' which is in abundance throughout the depth of the pedons' no other mineral' light or heavy' shows any definite trend of distribution along the depths of the pedons. No definite relationship appears to exist between the nature of these skeletal minerals and growth' development and distribution of the vegetation of the area.

Abstract

Clay mineralogical characterisation of soils of four different natural vegetational sequences of South Kheri forest division has been attempted. Sand mineralogical analysis revealed that the soils have developed from the same source. Hence differences in their characteristics might have been triggered off by the diversity in their vegetative cover. Ellite was present in all the soils with different relative propositions. Vermiculite, mixed minerals and chlorite seem to be present in higher amount in Argiustolls, Haplustolla and Haplustalfs having more diversity in their natural vegetation. Ellite dominated in Ustochrepts under a purest and of Shorea robusta. More alteration of Ellite or neo-synthesis of vermiculite and chlorite seems to have taken in soils with comparitively wet soil moisture regims as evidenced from the natural groeth of moisture loving indicator species like Syzygium cumini and Terminalia alata.

Abstract

Some soil biosequences occurring on a nearly similar toposequence have been classified with special reference to the role of natural vegetation on thier genesis. Sandy hyporthermic typic Haplumbrept and Ustochrepts are the major silviculturally important soils of this area. From the organic carbon content (Organic productivity turn-over) and its relative distribution along depth, comparision of base status in different horizons and clay migration, it appears that marks of grassy woodland ecotones on the genesis of Argiustoils are quite evident. Thick B-horizons, migration of clay, lower base saturation, gradual decrease in organic carbon and redistribution of exchangeable Ca and Mg possibly due to phytocycling among various horizons indicate the dominant role played by tree species in the comparatively more weathered habitats of Udic Haplustalfs. Silvicultural suitability of different taxas have been discussed.

Abstract

The clay mineralogy of soils from the moist teak forests of South Chanda Forest Division (Maharashtra) indicates that illite and kaolinite are the dominant minerals and quartz occurs as an accessory mineral in the clay fraction. The soils are well drained and kaoliniziation is the dominant clay forming process as indicated by the clay mineralogy It is inferred that the loss of bases due to kaolinization may not get adequately replenished by the nutrient cycling through inorganic and organic substances, if the balanced ecosystem is disturbed. It is, therefore, necessary to protect these forests against over exploitation for sustained yield and site protection.

Abstract

The lateritic soils of East Midnapur Forest Division, West Bengal are low in the physico-chemical agents responsible for soil aggregation except total and free iron oxides. The state of aggregation of the five depths studied considered along with the vertical distribution pattern of free iron oxides and of clay in these soils indicate that free iron oxides have participated rather actively in the formation of the non dispersible aggregates stable to water action. The trend of distribution and the relationships of the free iron oxides vis-a-vis aggregation has been discussed.

Abstract

In order to quantify and document the influence of forest fire on physico-chemical and moisture characteristics of soil, a study was and undertaken in Sukna I, Kurseong Forest Division, West Bengal. Fire affected the soil by drastic reduction of organic carbon, total nitrogen, cation exchange capacity, exchangeable calcium and magnesium, available P₂O₅ and K₂O. Soil reaction became less acidic. Moisture characteristics of the affected soils were radically changed with substantial reduction in 1/3-bar moisture as well moisture retention at different tensions, and inability to retain any moisture beyond 8.l-bar tension. Water holding and available water capacities were considerably reduced.

Abstract

A comparative study of two sites, one representing the sal-chander and the other contiguous sal forest ecotone, was made in a part of South Kheri Forest Division, U.P. to determine the properties of the soils of the two sites, bring out the salient differences between them, and to establish hypothesis as to their origin. The study revealed that the soils of the two sites differ considerably in most of the physico-chemical properties and moisture characteristics. The soils of Chanders are of comparatively), recent origin and the grassy vegetation, perhaps the early colonizer, is the result of immaturity of the habitat possessed with unfavourable edaphic factors. Adjoining sal forest area is a habitat of mature edaphic sequence with better soil development and the invasion by sal from the periphery inwards indicates the progress of the succession form grassland to woodland.

Abstract

Soil study ot the Upper Sipra river catchment reveals the occurrence or four genetically different soils in association and their characteristics are very much influenced by their physiographic situations. Topography appears to play the dominant role in deciding their characteristics and the most important functional aspect of topography in this regard is perhaps its effect on the drainage, both internal as well as external. This broad-based categorization with some additional information, as and where necessary, may provide informatioa for soil and land use planning of the area.

Abstract

The study was conducted to determine the characteristics of termite-Roils in relation to the soils of the surrounding and to know whether the termite-soils originate from the top soil or the subsoil. The termite-soils are characterized by higher proportion of finer fractions-clay and silt, higher organic matter and total nitrogen, better water holding capacity, higher base status, exchange capacity, p^H, and total CaO and MgO as compared to the surrounding soils. Quantitatively total K₂O is considerably lower than the surrounding top soils as well as subsoils, and total P₂O₅ is at par with the subsoil but higher than the top soil. The available traction or K₂0 is almost equal in the inner mass of the termite- soil and the subsoil but higher than the outer crust and the top soil.

Abstract

A considerable difference in the nature or humus was observed in the two typical sal forest soils of Doon Valley. The humus of the soils obtained from Asarori is predominantly humic in nature with greater condensation of aromatic rings and thus more mature as compared to that of Jhajra which is more lignious and fulvic in nature, containing more of side chains. Greater hydrolysability, oxidisability and mobility of humus of Asarori have been responsible for better soil conditions from the point or view of site quality and also nutrient cycling.

Abstract

Ventilagineae, a tribe under Rhamnaceae has about 47 species (Suessenguth, 1953), scattered over the tropics of Asia, Africa, Australia and the Polynesian islands. The area taken up for this revision is India, including the Andaman and Nicobar group of islands. This tribe includes two closely related genera: Smythea Seem. ex A. Gray and Ventilago Gaertn., mainly distinguishable on a single character, viz., the nature of the fruit. Four species and a variety of Ventilago and four species of Smythea have been described here from the area under study. Efforts have been made to give full descriptions with synonymy of the taxa treated here along with critical notes and workable keys to facilitate correct identity.

Abstract

A comparison of the methods employing five commonly used extractants for the determination of available-P was made on eleven different types of forest soils. Morgan's 10% CH₃COONa in 3% acetic acid buffered at pH 4.8 was most effective in extracting the highest values of available-P in 19 samples out of 22 under study, followed by Dyer's 1% citric acid extractant. Troug's extractant compared well with the Olsen's but both gave very low values. Bray's 0.03 N-NH₄F and 0.025 N HCl extracted lowest values of available-P in the majority of the samples studied. The results indicate that Morgan's method should be used for the routine estimation of available-P in different types of forest soils.

Abstract

Trend in the changes in peroxidisable, alkali-extractable, and acid-hydrolysable fractions of the soil organic matter under Eucalyptus monoculture and surrounding natural sal in the course of a quinquennium reveals that the former humifies easier and faster. Oxidisability of resistant organic matter of the surface samples increases under both but the non-peroxidisable carbon decreases in all the layers under Eucalyptus as compared to surrounding sal. Optical densities of the alkali- extractable organic fraction, in general, increases and more so in the surface layers, reflecting certain changes in the nature of the organic matter returned during this period. Translocation of the humified material is more pronounced under Eucalyptus although to a limited depth. Soil organic matter under Eucalyptus is more hydrolysable, and non-hydrolysable fractions decrease very significantly under sal as compared to Eucalyptus.
