the main purpose of this research was to analyze agricultural water management problems (awmp) in three contexts of: water source, water conveyance and at the farm level, in zarrindasht county, fars province. the research was carried out based on a survey method with a questionnaire compiled for collection of data. questionnaire's reliability was confirmed through a computation of cronbach...

To assist water resource managers with future land use planning efforts, the eco-hydrological model Soil and Water Assessment Tool (SWAT) was applied to three catchments in South Australia that experience extreme low flow conditions. Particular land uses and management issues of interest included forest covers, known to affect water yields, and farm dams, known to intercept and change the hydro...

The plurality of conservation and environmental viewpoints often challenge community leaders and government agency staff as they seek to engage citizens and build partnerships around watershed planning and management to solve complex water quality issues. The U.S. Midwest Heartland region (covering the states of Missouri, Kansa, Iowa, and Nebraska) is dominated by row crop production and animal...

ABSTRACT- Efficient use of irrigation water for summer crops should be considered seriously due to rare occurrence of precipitation in summer. This research was focused on the assessment of water use efficiency for dominant crops of summer cropping pattern in the study area (i.e., maize and rice) via considering water productivity (WP) with different water management scenarios at farm level at ...

After about a decade invested in development of plant-based techniques to diagnose tree water status in orchards, midday Stem Water Potential (SWP) is being adopted at the farm level as a irrigation management tool in orchard crops such as walnut and almond. An alternative technique referred to as midday, shaded Leaf Water Potential (LWP) has also been developed for use at the farm level. Effec...

Farmland management involves several planning and decision making tasks including seed selection and irrigation management. A farm-level precision farmland management model based on mixed integer linear programming is proposed in this study. Optimal decisions are designed for pre-season planning of crops and irrigation water allocation. The model captures the effect of size and shape of decisio...

Groundwater levels rose (an average of 10m) (mostly in 1970’s and 80’s) due to irrigation induced recharge to the groundwater in Coleambally Irrigation Area (CIA). Water table depth rise was a direct result of the net amount of recharge over and above the regional groundwater outflow capacity. Control of net recharge through a range of options is critical to the sustainability of CIA and requir...

With the continuing pressure on Australia’s water resources and interand intra-annual rainfall variability, farmers, especially in rainfed agricultural and pastoral zones, have been developing farm dams as a mean of providing additional water sources for irrigation and stock. The density of farm dams has increased over time, and an accurate knowledge of the spatial distribution of farm dams is ...

We analyzed how three different dairy management systems –continuous grazing, confinement and management intensive grazingcompare across nine sustainability indicators set by the Dairy Stewardship Alliance. A self-assessment survey comprising animal husbandry, biodiversity, energy, community health, farm financials, nutrient, pest, water and soil management was assessed twice across the same fa...

Structural best management practices were implemented throughout the Cannonsville Reservoir Watershed (CRW) in an effort to reduce P losses to the reservoir. Yet long-term water quality control efforts within CRW are hindered by continuous P build-up in the soils resulting from dairy farm P imports exceeding exports. Addressing the P imbalance problems and maintaining economic viability of the ...
