Prediction of soil characteristics over large areas is desirable for environmental modeling. In arid environments, soil characteristics often show strong ecological connectivity with natural vegetation, specifically biomass and/or canopy cover, suggesting that the soil characteristics may be predicted from vegetation data. The objective of this study was to predict soil infiltration characteris...

Changes in land use the Air Dingin watershed (DAS) area Padang City, Indonesia, lead to a decrease rainwater infiltration volume ground. Some Latung sub-watershed capacity with an increase surface runoff. This research aims determine effect of land-use changes on and Purposive sampling method was used this research. The measured directly field using double-ring infiltrometer, data processed Hor...

Agricultural development with horticultural crops on dry land is one of the government's efforts to increase productivity so that new paddy fields are created in Bayan area. Noting infiltration capability and its classification important factors needed irrigation planning support agriculture, it necessary conduct field research this matter. This study aims determine characteristics trend can be...

We explore the current situation in a viticultural region Eastern Spain from holistic and multifaceted research approach, which allowed us to understand biophysical conditions, economic cost, social impact, perception of farmers’ community use catch crops. A survey farmers, an assessment impact crops (CC) tillage (C = Control plot) on soil organic matter, bulk density, infiltration capacity (si...

Due to increasing demand for limited water resources, the pressure on irrigation used in agricultural production is also increasing. One of alternative solutions meet needed use low-quality resources. However, these waters can cause serious problems environment, especially soil and plants, short, medium long term. The sodium concentration affects structure soil, infiltration rate hydraulic cond...

numerical instability can be problems. Therefore, the nonlinear least-squares regression method introduced Tension infiltrometer measurements have been used to measure by Logsdon and Jaynes (1993) has been widely used, steady-state infiltration rates at applied tensions. The measurements owing to its simplicity. They estimated saturated hycan be used to determined soil hydraulic properties thro...

in this paper, we study some ring theoretic properties of the amalgamated duplication ring $rbowtie i$ of a commutative noetherian ring $r$ along an ideal $i$ of $r$ which was introduced by d'anna and fontana. indeed, it is determined that when $rbowtie i$ satisfies serre's conditions $(r_n)$ and $(s_n)$, and when is a normal ring, a generalized cohen-macaulay ring and finally a filter ring.
