The potential for contamination of surface and ground water by atrazine, applied preand postplant in a Eucalyptus nitens (Deane & Maid.) Maid plantation is investigated as part of a wider based Australian study. These studies aim to provide forest plantation managers with a better understanding of the processes involved in the behaviour of atrazine in the Australian environment. This informatio...

soil hydraulic properties such as soil water characteristic curve are necessary prerequisite for modeling water movement and solute transport. direct methods of estimating these hydraulic properties are time consuming and costly. indirect methods, such as pedotransfer functions, estimate the hydraulic parameters using easy-to-measure soil properties like particle size distributions, bulk densit...

The persistence, movement and metabolism of insecticides in soils are affected by various environmental conditions. Field data are presented, showing that phorate—after granular band application—moved in both horizontal and vertical directions. Phorate sulphone was the major metabolite recovered. The metabolism and persistence of this insecticide was also affected by its mode of application. Ut...

The goal of this paper is to identify the military geographic factors that affect the cross-country mobility (trafficability of the terrain) and to cite some standardised procedures for establishing of these factors. Classification of the crosscountry movement levels. Influence of the slope, vegetation, water, soil, weather, urban area, transportation, and another features on the cross-country ...

Over one billion tons of agricultural, municipal, and industrial wastes with potential uses in agriculture are generated annually in the United States. Many of these materials are applied to agricultural land because of the benefits they provide. These benefits include: providing a nutrient source for crops; improving soil chemical, physical and biological properties; improving water storage an...

Wheat growth in response to soil water deficit play an important role in yield stability. A field experiment was conducted for winter wheat (Triticum aestivum L.) during the period of 2002–2005 to evaluate the effects of limited irrigation on winter wheat growth. 80%, 70%, 60%, 50% and 40% of field capacity was applied at different stages of crop growth. Photosynthetic characteristics of winter...

In irrigated agriculture, the study of various ways water infiltrates into soils is necessary [...]
