      Interactions of SOC with the soil mineral phase can modify the susceptibility of SOC to become mineralized. Pedogenic Fe‐, Al‐oxides and clay potentially affect SOC stabilization in highly weathered soils typically found in the humid tropics. The aim of our study was to determine the impact of different land uses on SOC stock on such soils.

      Focusing on Sumatra, a hotspot of tropical lowland rainforest transformation, we investigated effects of the conversion of rainforests into rubber agroforests (“jungle rubber”), intensive rubber, and oil palm plantations on the communities of litter and soil microorganisms and identified factors responsible for these changes. Litter basal respiration, microbial biomass, total bacterial. In recent years, fast-growing leguminous tree plantations has expanded in tropical Asia (FAO, ), and several studies have suggested that the plantations instead of indigenous tree species.

Because of the relatively recent recog- nition of the soil fauna as constituting a major controlling influence on the productivity of tropical ecosystems, only two important myths have emerged.

The impact of monoculture plantations of fast growing tree species on soils of the lowland humid tropics has been assessed by comparing soil conditions under natural forest, with those under plantations.

Suspended sediment yields in the tropical Andes vary by at least three orders of magnitude, from 50 t km − 2 year − 1 in the Cordillera Real to 50, t km − 2 year − 1 in the humid region of Chapare (Baby et al., ; Guyot et al., ). Baby et al. () estimated that the annual total mass of suspended sediment leaving the eastern Bolivian Andean and sub-Andean catchments is The soils of the humid tropics are highly variable.

Table shows the geographical distribution of soil orders and major suborders based on the soil classification system developed in the United States. Oxisols and Ultisols are the most abundant soils in the humid tropics, together covering almost two-thirds of the region.

Soil fertility capability assessment for use in the humid tropics. Characterization of Soils in Relation to their Management for Crop Production: Examples from the Humid Tropics, Greenland, DJ (ed.). Clarendon Press, London, pp. – The negative impact of fast-growing tree plantations, especially when grown in short rotations, on nutrient reserves of poor tropical soils is often described.

The intensity of soil and forest degradation may be assessed by different approaches, including detailed observation of deficiency symptoms and yield development, foliar and soil. On average, D. giganteus, D. hookerii and B. nutans were found to be the better species for restoring soil fertility status in humid tropics of the NEH region, India.

The soil properties most likely to influence species composition in lowland tropical rain forests are, in decreasing order of importance: P availability, Al toxicity, drainage, water‐holding capacity, and availability of K, Ca, and Mg.

A total of 18 studies were located in which species occurrence was studied in relation to such soil properties.

Jari plantation is the largest pulp growing operation in the humid tropics, and occupies about sqkm previously covered by tropical forest. A study of five sites at Jari in indicated declining soil fertility, and low productivity of pulpwood.

Low pulp production at Jari was caused by several factors, one of which appeared to be low soil fertility. The sams sites were re-evaluated in. The American soil scientist E. W. Hilgard together with V. V. Dokuchaev, founder of modern pedology (Jenny, ), thought that soils of the humid tropics were rich in humus because of the abundant vegetation supplying plant material (Hilgard, ).Soil acidification is a major factor limiting the sustainability of agricultural production systems throughout the world.

Liming may not always be economically possible and therefore alternative methods or complementary methods of amelioration are required. Leaf litter collected from several tree species was examined for ash alkalinity (as an estimate of organic anion content) and ability to.A.K.M.
