Two experiments were conducted to examine the influence of kaolinite clay supplementation (0%, 1%, or 2% diet dry matter [DM] basis) on characteristics of digestion (Trial 1) and growth performance (T...
Irrigation with treated wastewater is essential for increasing crop production in arid and semi arid regions. Field experiments were conducted on rainfed clayey soil to investigate the impact of water...
Soil clay content (SCC) plays an essential role in the processes of infiltration, seal and crust formation, runoff, and soil erosion. The role played by SCC in water erosion has received much attentio...
The single-porosity and dual-permeability models in HYDRUS-1D (Šimůnek et al. 1998, 2003) were used to simulate variably-saturated water movement in clay soils with and without macropores. N...
A laboratory incubation experiment was carried out for 85 days to monitor the N mineralization during the decomposition of 15N labeled wheat and rice straws incorporated at 5 g kg-1 soil at varying te...
Field experiments were conducted during Kharif 2006 and 2007 in clay loam soil to study the effect of organic sources and urea on N transformation and yield of rice. The treatments consisted of addit...
To develop a reforestation method for devastated land, the author investigated the behavior of seeds in clay pellets as reforestation materials in the Matsukisawa Basin in Ashio. In the case of a seed...
At mid-elevation terraces in the southern part of Sumatra Island, Indonesia, cassava is widely cultivated as one of the most important cash crops for farmers. However, the prominent cassava cultivatio...
The effects of mixed coating of seed with oxygen-generating chemicals containing 16% calcium peroxide (CaO2) and clay on the seedling emergence of rice (Oryza sativa L.) from flooded soil were examine...
Water availability is one of the determinants of productivity of rainfed lowland rice (Oryza sativa L.). Quantifying water losses from a paddy field, such as deep percolation and lateral seepage, assi...
In Hokuriku area, the field converted from heavy clay paddy is often wet, but most of soybean is cultivated in such fields. Soybean differentiates flower buds in the rainy season, which is from late ...
The changes of mineral nitrogen content in clay loam Cambisol in sustainable and organic agriculture.
This study was designated to determine the effect of different applied water by use of different emitter discharges on the wetting patterns of a loam or clay-loam soil under trickle source. Irrig...
Soil tensile strength (TS) and aggregate stability (AS) values can be used as indicators of soil structural quality. The objective of this study was to determine the influences of land use types, soil...
Studies of clay mineralogy and related chemical composition are rarely connected with implications for soil management in the field. However, this study attempts to manifest the practical utilization ...
