Phosphorus Nutrition of Lowland Rice in Tropical Lowland Soil

Communications in Soil Science and Plant Analysis, 2013
Rice is a main food crop for about half of the world's population, and phosphorus (P) is the main limiting nutrient in rice production in tropical lowlands. A greenhouse experiment was conducted to evaluate P requirements of lowland rice grown on a lowland soil (Inceptisol).

The Soils of the Lowlands

2014
The lowland soils represent the heavy use of our land resources being easily accessible to the general populace. These are the flat areas located between the sea and the surrounding uplands, hills, and mountains. The alluvial flood plains, being dissected by a meandering river, are regularly visited by floods.

Automorphic taiga soils of the Sredneobskaya Lowland

Eurasian Soil Science, 2012
The morphology of the profile, some chemical properties, and particle-size distribution of the automorphic soils developed from lacustrine-alluvial loamy-clayey deposits in the Sredneobskaya Lowland are considered. The soils of the West Siberian middle taiga zone remain poorly studied.

Carbohydrates and aggregation in lowland soils of Nigeria as influenced by organic inputs

Soil and Tillage Research, 2004
We evaluated the influence of several organic matter management practices on the characteristics of carbohydrates in water-stable aggregates and soil aggregate stability at three Nigerian locations (Abakiliki, Nsukka and Umudike) where forests had been converted to arable farming.

The amoeboid protists of cryogenic soils in the Kolyma Lowland

Eurasian Soil Science, 2013
The taxonomic diversity of amoeboid protists was examined in three types of tundra soils in the Kolyma Lowland, namely, a podzolized podbur, a cryozem, and a gleyzem. In total, 27 naked amoeba genera were identified in the analyzed samples. It was shown that the individual soil types house different communities of naked amoebas.

Soil-Moisture-Temperature for Alaskan Lowland

Journal of the Irrigation and Drainage Division, 1975
Measurements of annual pore-water pressures and temperatures in a well-drained lowland and a tussock suprapermafrost soil indicate a complex sequence of events with the most dynamic and significant behavior occurring in the winter months. Vertical water movement in the soil profiles during the summer months is negligible, the well-drained soil being ...

Soil aeration status in a lowland wet grassland

Hydrological Processes, 2004
AbstractThe maintenance or development of plant community diversity in species‐rich wet grasslands has been a focus of water management considerations in the UK for the past 20 years. Much attention has been given to the control of water levels in the ditch systems within these wet grassland systems.

PHYSICAL PROPERTIES OF GLEYSOLIC SOILS IN THE LOWLANDS OF QUEBEC

Canadian Journal of Soil Science, 1979
Clay-rich soils were sampled in the agricultural areas of Montreal, Quebec and Lake St-Jean. Undisrupted soil blocks and bulk samples were taken by horizon in the Ste-Rosalie, Kamouraska and Normandin soil series. Aggregate stability increased with the organic matter content. Bulk density was generally highest in the B horizons.

Soil-Scratching Behaviour by Western Lowland Gorillas

Folia Primatologica, 1991
Soil-scratching behaviour by western lowland gorillas (Gorilla gorilla gorilla) was recognized in a field study in the Ndoki forest of northern Congo. The purpose of this behaviour was probably insect eating although the harvest of insects was likely to be relatively poor.

Chemistry of Lowland Rice Soils and Nutrient Availability

Communications in Soil Science and Plant Analysis, 2011
Rice is the staple food crop for about 50% of the world's population. It is grown mainly under two ecosystems, known as upland and lowland. Lowland rice contributes about 76% of the global rice production. The anaerobic soil environment created by flood irrigation of lowland rice brings several chemical changes in the rice rhizosphere that may ...
