Simulation Of Nitrous Oxide Emissions In Zoysia Turfgrass Using Daycent And Dndc Ecosystem Models, Mu Hong, Yao Zhang, Ross Braun, Dale J. Bremer
Simulation Of Nitrous Oxide Emissions In Zoysia Turfgrass Using Daycent And Dndc Ecosystem Models, Mu Hong, Yao Zhang, Ross Braun, Dale J. Bremer
Kansas Agricultural Experiment Station Research Reports
Nitrous oxide (N2O) is an important greenhouse gas (GHG) implicated in global climate change. Process-based ecosystem models, such as DAYCENT and DNDC, have been widely used to predict GHG fluxes in agricultural systems. However, neither model has yet been applied to warm-season turfgrasses such as zoysiagrass. This study parameterized, calibrated, and validated the DAYCENT and DNDC models for N2O emissions from Meyer zoysiagrass (Zoysia japonica Steud.) using Bayes’ theorem and field data from Braun and Bremer (2018a, 2019) and Lewis and Bremer (2013). Results indicated DAYCENT, but not DNDC, reasonably simulated the impacts of irrigation …
Extending Sustainable Irrigation Opportunities To Socially And Historically Disadvantaged Farmers In The Alabama Black Belt To Support Commercial-Level Production, Raymon Shange, Richard Martin, Victor Khan, Kwesi Daniels, George X.

Extending Sustainable Irrigation Opportunities To Socially And Historically Disadvantaged Farmers In The Alabama Black Belt To Support Commercial-Level Production, Raymon Shange, Richard Martin, Victor Khan, Kwesi Daniels, George X. Hunter, Gwendolyn J. Johnson, Steve Musser, William Puckett, Walter A. Hill
Professional Agricultural Workers Journal
This paper focuses on providing sustainable irrigation opportunities to socially and historically disadvantaged farmers (SHDFs). The ability to provide steady production capacity through the use of renewable energy sources and microirrigation is innovative, in that it demonstrated how to develop and utilize a sustainable irrigation system in both energy and water conservation. This venture is also innovative in that it sought to provide SHDFs with irrigation in a state in which irrigation in agriculture is minimal, while at the same time, offsetting the energy costs that normally accompany irrigation. Several farmers are profiled in their participation in the irrigation program. …

Land Use Planning For Agriculture And Sustainable Rural Development, Ian Kininmonth, Andrew Bathgate, Ross George, Dennis Van Gool
Land Use Planning For Agriculture And Sustainable Rural Development, Ian Kininmonth, Andrew Bathgate, Ross George, Dennis Van Gool
Journal of the Department of Agriculture, Western Australia, Series 4
An important goel for agriculture will be to achieve sustainable land use patterns and management systems.
Land use planning has a role to play in helping agticulture achieve this goal. Ian Kininmouth, Andrew Bathgate, Ross George and Dennis Van Gool discuss the directions land use planning could follow.
Irrigation And Fertilizer Management For Horticultural Crops On The Swan Coastal Plain, I R. Mcpharlin, Greg Luke
Irrigation And Fertilizer Management For Horticultural Crops On The Swan Coastal Plain, I R. Mcpharlin, Greg Luke
Journal of the Department of Agriculture, Western Australia, Series 4
The Swan Coastal Plain is an important area for the production of vegetables, flowers and fruits in Western Australia. The yellow Cottesloe, Karrakatta and the white-grey Bassendean Sands upon which most of this production is based are infertile in their natural state and require large inputs of fertilizer for succesful production of horticultural crops.
Improved irrigation and fertilizer management will be needed to reduce nutrient leaching from horticultural crops on the coastal plain. This will probably involve applying fertilizer and water more frequently, but in smaller quantaties thaan currently practiced. The result should more closely match water and fertilizer supply …
Draining Irrigation Areas, K S. Cole, J P. Middlemas
Draining Irrigation Areas, K S. Cole, J P. Middlemas
Journal of the Department of Agriculture, Western Australia, Series 4
Many irrigation schemes throughout the world have turned into unproductive saline flats and swamps. This dramatic change can occur within a few years of irrigation starting and has been part of irrigation schemes from earliest times up to the present day.
The main cause of this salinisation is normally excess irrigation water use combined with poor drainage. Any form of waterlogging will have an adverse effect on plant growth.

Irrigation In South-Western Australia, K S. Cole
Journal of the Department of Agriculture, Western Australia, Series 4
THE pattern of irrigation in South-Western Australia is constantly changing, At present, the main increase is in the private sector.
In the past century, there has been a see-saw effect from private to Government to private schemes.
Irrigating With Underground Water, T C. Calder
Irrigating With Underground Water, T C. Calder
Journal of the Department of Agriculture, Western Australia, Series 4
MANY farmers in South-West areas are looking to irrigation to increase and diversify farm production, particularly on the sandy coastal plain where irrigation in summer is essential for vegetable, fruit and fodder production.

Private Irrigation Systems : Do They Pay?, G D. Oliver
Journal of the Department of Agriculture, Western Australia, Series 4
WESTERN AUSTRALIA, with 71,000 acres under irrigation, can hardly claim to have an important irrigation farming industry.
However, irrigation is daily growing in importance, especially through private schemes. These account for almost half the present irrigated area.
Land Grading In South West Irrigation Areas, 1966-67, Department Of Agriculture, Western Australia
Land Grading In South West Irrigation Areas, 1966-67, Department Of Agriculture, Western Australia
Journal of the Department of Agriculture, Western Australia, Series 4
Land grading in the South West Irrigation Areas with modern earth moving equipment first commenced in 1949.
The advantages of land grading are well recognised by farmers and this season grading operations were carried out on 208 farms.

The Hamel Nursery, K S. Cole
Journal of the Department of Agriculture, Western Australia, Series 4
A LITTLE known, but highly productive use of irrigation water occurs at the Forestry Department Nursery, Hamel.
Seedlings of trees and shrubs are raised during the summer for sale the following winter.
Sales are made to the farming community and many trees are used by the Forest Department in its reafforestation programmes.

Hints On Irrigating Citrus With Saline Water, Stanley Thomas Smith
Journal of the Department of Agriculture, Western Australia, Series 4
IN the past few years a number of citrus orchards near Perth have shown signs of damage caused by excess "salt" (chloride) uptake. All have been irrigated either from the Canning River or from private bores or dams.
Senior Soil Research Officer S. T. Smith describes glasshouse experiments which have given some useful guides to minimising "salt" damage in citrus trees irrigated with low-quality water.

Irrigation In Western Australia : Report On Government-Controlled Areas : 1958-59, H K. Gibsone
Journal of the Department of Agriculture, Western Australia, Series 4
IRRIGATION in the south-western portion of Western Australia is mainly confined to the coastal plain west of the Darling Range where the three main irrigation districts of Harvey, Collie and Waroona have been established by the State Government.
The Government-controlled irrigation areas extend southward from Waroona (70 miles from Perth) to Dardanup (120 miles from Perth) and have an average width of about five miles.
Water Usage Trials With Bananas On The Gascoyne, W M. Nunn
Water Usage Trials With Bananas On The Gascoyne, W M. Nunn
Journal of the Department of Agriculture, Western Australia, Series 4
THE banana industry at Carnarvon is an unusual one by most agricultural standards.
Normally a tropical plant liking relatively humid conditions in a high rainfall, the banana is cultivated at Carnarvon in an area of extremely low rainfall and with relatively low humidity throughout the year.
Water is pumped to irrigate the crop from the sands of the Gascoyne River bed or from bores adjacent to the river course.
