Using Forages To Conserve Water In Semi-Arid Irrigated Cropping Systems, Rick Kellison, V. G. Allen, C. P. Brown, D. L. Doerfert, P. N. Johnson, S. J. Maas, C. P. West

IGC Proceedings (1993-2023)

The Texas High Plains are part of the largest, contiguously irrigated cropland in the USA, and draws water from the Ogallala aquifer. High crop prices, increased demand for maize for ethanol production, and severe drought have increased water depletion rates. Research has shown that integrating forages and grazing cattle into the cotton-dominant cropping system can reduce overall water use (Allen et al. 2012) while still offering farmers positive net returns (Johnson et al. 2013). Integrating forages with row crops also reduces needs for nitrogen (N) fertilizer, rebuilds soil organic matter (Acosta-Martinez et al. 2010), and reduces fossil energy …

Flexible Forage Systems For Variable Water Supplies, Mary-Jane E. Rogers, Alister Lawson, Kevin Kelly Mar 2020

Flexible Forage Systems For Variable Water Supplies, Mary-Jane E. Rogers, Alister Lawson, Kevin Kelly

IGC Proceedings (1993-2023)

The dairy industry in northern Victoria, Australia is primarily based on the border check irrigation of temperate forage species over the spring to autumn period. Traditionally, dairy cows have grazed the perennial species (white clover and perennial ryegrass) and annual pastures (based on short-lived ryegrasses and subterranean or Persian clover). However, due to a more variable climate – particularly a period where the annual rainfall has been significantly less than the long-term average – the summer irrigation allocations have been substantially lower and more variable than the preceding 20-30 years. Under this climate scenario, dairy farmers are re-evaluating their feed …

Delayed Sowing Decreased Lucerne Dry Matter Yield Over Two Seasons, Richard Sim, Derrick Moot Mar 2020

Delayed Sowing Decreased Lucerne Dry Matter Yield Over Two Seasons, Richard Sim, Derrick Moot

IGC Proceedings (1993-2023)

Lucerne (Medicago sativa L.) can be sown in New Zealand from late spring (October) to early autumn (March). In the establishment season, greatest drymatter (DM) yields are normally attained from sowing early and production lost from delayed sowing is only considered in the establishment season. The objective of this research is to determine if sowing date continues to have an effect on DM yield in year two and how the partitioning of DM between the above and below ground plant fractions is influenced by sowing date.

Managing Water Resources In Australian Temperate Pastures, David Mitchell Mar 2020

Managing Water Resources In Australian Temperate Pastures, David Mitchell

IGC Proceedings (1993-2023)

Increasing the amount of perennial vegetation changes the water balance at both farm and catchment scale. At the farm scale, changes to the flows of water and salt are generally as expected, though some perverse outcomes may occur, such as a shortage of surface water for stock. From a catchment perspective, downstream users are little affected by decreases in streamflow volumes, river flows appear to be more typical of pristine flows, and upstream landholders benefit from improved resilience.

Global Pattern And Change Of Cropland Soil Organic Carbon During 1901-2010: Roles Of Climate, Atmospheric Chemistry, Land Use And Management, Wei Ren, Kamaljit Banger, Bo Tao, Jia Yang, Yawen Huang, Hanqin Tian

Plant and Soil Sciences Faculty Publications

Soil organic carbon (SOC) in croplands is a key property of soil quality for ensuring food security and agricultural sustainability, and also plays a central role in the global carbon (C) budget. When managed sustainably, soils may play a critical role in mitigating climate change by sequestering C and decreasing greenhouse gas emissions into the atmosphere. However, the magnitude and spatio-temporal patterns of global cropland SOC are far from well constrained due to high land surface heterogeneity, complicated mechanisms, and multiple influencing factors. Here, we use a process-based agroecosystem model (DLEM-Ag) in combination with diverse spatially-explicit gridded environmental data to …

Soil Quality Parameters And Carbon Stock As Influenced By Fodder Grasses And Organic Amendments In An Alfisol Of Northeastern India, Anup Das, G. Ramkrushna, Jayanta Layek, A. S. Panwar, S. V. Ngachan, D. P. Patel

IGC Proceedings (1993-2023)

Intensive tillage, cultivation along the slope, low input, minimal nutrient replacement and high rainfall are among major causes of land degradation in the north eastern hill (NEH) region (Ghosh et al. 2009). Maintaining and enhancing soil quality are crucial to sustaining agricultural productivity and environmental quality (Lal, 2004). Continuous cropping, without use of conservation-effective measures, has negative effects on the soil and environment (e.g., loss of SOC, soil erosion, water pollution). Thus, soil management methods are needed that enhance use efficiency of inputs, reduce losses and minimize adverse impacts on the environment (Bilalis et al. 2009). Perennial grasses provide …

A Method For Assessing Multiples Ecosystem Services From Grasslands Based On Vegetation Characteristics. An Example From Norwegian Semi-Natural Grasslands, Simon Taugourdeau, Line Johansen, Sølvi Wehn Feb 2020

A Method For Assessing Multiples Ecosystem Services From Grasslands Based On Vegetation Characteristics. An Example From Norwegian Semi-Natural Grasslands, Simon Taugourdeau, Line Johansen, Sølvi Wehn

IGC Proceedings (1993-2023)

Ecosystem services are human benefits provided by ecosystems and related to the characteristics of the vegetation (de Bello et al., 2010).Semi-natural grasslands provide a large set of ecosystem services and are thus important ecosystems in boreal landscapes. The vegetation of semi-natural grasslands differ regarding land use, soil and climate. Consequently, also provision of ecosystem services from semi-natural grasslands will vary among various types of semi-natural grasslands. Here, we propose a method to develop indicators of ecosystem services from semi-natural grassland using the DEXI® software (Bohanec and Raikovic, 1990).

The Value Of Modeling Botanical Composition Change In Grasslands, Karl Behrendt

IGC Proceedings (1993-2023)

The integration of grassland dynamics, livestock production and economics is necessary to improve decision making regarding grassland resource development and management. Within a sward, the relative competitive ability of different species and the way management interacts with the environment both play a significant role in determining the competition between species, future states of the grassland sward, ecological impact of the grassland and its potential for livestock production (Kemp and King, 2001). The impact of botanical composition shifts on grassland productivity will depend on the nutritive value and yield potential of the invasive species against those of the resident species. The …

Range Dynamic And Sustainability Of Mediterranean Grassland, Zalmen Henkin, Eugene D. Ungar, Avi Perevolotsky, Yehuda Yehuda, Serge Landau, Marcelo Sternberg

IGC Proceedings (1993-2023)

Mediterranean grasslands are a highly diverse and complex ecological resource of considerable economic and environmental importance. Herbaceous plant production that determines the carrying capacity of these grasslands for beef cattle husbandry is not only influenced by climatic factors, habitat characteristics, soil fertility and depth, but also by the stocking density and the nature of the grazing system (Gutman et al., 1999). The yearly Mediterranean pasture cycle is characterized by a temperate, winter-spring growing season and a hot, dormant, summer-autumn dry season. Consequently, pasture growth dynamics result in extremely low biomass availability at the beginning of the rainy season and …
