Bamboos commonly kown as woody grass are one of the most important species particularly in Asia, where it is frequently considered as the ―timber of the poor‖ (Rao et al., 1985). With about 23 genera and 136 species, India is the second largest reservoir of bamboos, next only to China (SFR, 2013 and Nath et al., 2009). Bamboos occur extensively in the managed ecosystems of India—both as plantations (and in agroforestry (scattered clumps, hedgerows on farm boundaries etc.

Dendrocalamus strictus L. is most commonly found bamboo in India. It is widely distributed in dry deciduous forests and grows rapidly ...

International Grassland Congress Proceedings

Ruminants have the capability to ferment structural carbohydrates found in forages and obtain from them a usable form of energy to produce high quality food, i.e milk and meat (Kamra et al., 2012). However, as a gaseous by-product from the enteric fermentation of those carbohydrates, methane is produced in a significant proportion, being considered as one of the most important greenhouse gases (GHG). In Colombian tropical livestock, inclusion of legumes in on poor quality grasses diets based have allowed an improvement of their nutritive quality, besides enteric methanogenesis reduction because their content of condensed tannins (CT); however, this is ...

The US EPA has defined Super Fund sites for 594 toxins in the United States. The EPA definition of toxins is one that causes acute or chronic human health effects, or causing significant environmental harm. One of the categories of toxins is nitroaromatic molecules, which are used primarily as munitions. In the United States alone there are 16,000 Department of Defense (DoD) sites. The most common munitions there are TNT, RDX, HMX, and 2,4 DNT. In the world, these sites range historically from World War II residues to those from recent Middle East conflicts. Human health effects from ...


Comparison Of Two Different Pasture Species Compositions For Recovery Of Deep Soil Nitrogen During Winter, Brendon Malclom, Keith Cameron, Grant Edwards, Jim Moir, Hong Di 2020 The New Zealand Institute for Plant & Food Research Ltd., New Zealand

Comparison Of Two Different Pasture Species Compositions For Recovery Of Deep Soil Nitrogen During Winter, Brendon Malclom, Keith Cameron, Grant Edwards, Jim Moir, Hong Di

International Grassland Congress Proceedings

Surplus nitrate (NO3-) beneath animal urine patches is highly vulnerable to leaching, particularly during winter when soil drainage is often highest. Most common pastures in New Zealand (i.e. Lolium perenne) have relatively shallow root systems and produce low dry matter (DM) yields during winter months. Recent investigations suggest that alternative pasture species may be able to recover more soil nitrogen (N) during winter and consequently reduce NO3- leaching losses (Moir et al., 2013; Malcolm et al., 2014; 2015). However, further work is required to better understand the importance of root system architecture and plant growth of these ...

Effect Of Selected Tanniniferous Leaves On In Vivo Enteric Methane Emission In Sheep, M. Saravanan, R. Bhatta, L. Baruah, P. K. Malik, N. Ravi

International Grassland Congress Proceedings

Concentration of methane is continuously increasing in atmosphere and now almost 155% (IPCC, 2007) more than that recorded during pre-industrial era. Livestock production is a major sector accountable for high methane emission into atmospheric pool. World’s livestock is contributing around 15% of total atmospheric methane on annual basis feeds (Moss et al., 2000). Additionally, methane emission from ruminants leads to a loss of 2 to 15% of the dietary energy (Holter and Young, 1992). Due to these two crucial issues, researchers are working tirelessly to find a suitable and effective way for enteric methane amelioration accompanied with minimal inputs ...

International Grassland Congress Proceedings

The quantification of methane (CH4) from enteric fermentation related to cattle diet is a useful tool to identify strategies to mitigate greenhouse gas emissions. This is even important in tropical and subtropical regions due to the lack of CH4 estimations in beef cattle, particularly from Bos Indicus breeds grazing tropical grasses (Kurihara et al., 1999). Several modelling approaches have been developed in order to predict CH4 emission. However, the use of these models has limitations associated with uncertainty information required such as feed intake (FI), composition of the selected diet and animal responses (Gonzalez et al., 2014 ...

International Grassland Congress Proceedings

Livestock in the country are primarily being fed on fibrous feed resulted in high enteric methane (CH4) emission along with low nutrients availability to host animal. Rumen methano genesis is necessary for the host system as this process ensure the removal of fermentative H2 through the reduction of CO2 into CH4. At the same time this process is wasteful because the emission also represents a loss of dietary energy (6-12% of gross energy intake) apart from contributing to global warming.

Worldwide livestock contribute around 90-95 Tg methane to the pool with a contribution of 12-13% from ...

Gross Biomass And Root/Shoot Ratio Mediated Drought Sensitivities Of Ecosystem Carbon Exchange In A Meadow Steppe, Yunbo Wang, Wei Sun, Deli Wang

International Grassland Congress Proceedings

According to IPCC’s Report (2007), global precipitation regimes will change largely in the future, with more annual precipitation at the mid-latitude regions. Simultaneously, due to the accelerating industrialization and use of nitrogen (N) fertilizer, significant increase in nitrogen deposition has been widely documented (Liu et al., 2013).

Water and nitrogen are the two most important limiting factors for the ecological processes of arid and semi-arid grassland ecosystems; therefore, altered precipitation regimes and enhanced nitrogen deposition are likely to change vegetation composition, ecosystem productivity, and aboveground vs belowground biomass distribution.

In addition to these long-term changes, short-term climate extremes, such ...

Spatial Heterogeneity Of Soil And Vegetation Characteristics And Soil-Vegetation Relationships Along An Ecotone In Southern Mu Us Sandy Land, China, Yingzhong Xie, Kaiyang Qiu, Dongmei Xu, Richard Pott

International Grassland Congress Proceedings

Spatial pattern analysis is an essential component of spatial heterogeneity studies on soil properties and vegetation characteristics. It was conducted in several studies for both soil and vegetation characteristics (Strand et al., 2007; Dick and Gilliam, 2007; Zuo et al., 2010). This study aims to examine the changes in the spatial heterogeneity of soil properties at different soil layers, the spatial heterogeneity of soil and vegetation characteristics along an ecotone, and soil-vegetation relationships along the ecotone in a critical area of desertification.

Long term monitoring of grassland being the largest ecosystem on earth plays an important role in understanding its productivity and transformation (changes) over time. With the availability of remote sensing data, most ecological and environmental problems caused either by human activities such as extensive agriculture, pastoralism which might lead to desertification, land degradation, loss of biodiversity and climate change amongst others can be monitored. For this study, vegetation cover was selected as the main source of examination and subsets of area covered with grasslands were profiled for further monitoring of grassland increasing and decreasing trends in selected areas of Central ...
