Cattle production is limited by forage availability during the dry season since water and soil fertility are the main factors limiting production. Leucaena leucocephala has good nutritive value (24-30% CP). It can stand drought and grazing and so its introduction into pastures is recommended as an alternative to forage production during the dry season. The aim of this study was to assess the effect of the introduction of L. leucocephala with different densities on biomass production of P. maximum and soil water content.

The Effect Of Extremes In Soil Moisture Content On Perennial Ryegrass Growth, A. Scott Laidlaw
IGC Proceedings (1997-2023)
Seasonal distribution of rainfall in the UK and Ireland is predicted to become more variable (Sweeney, 2003). The problems of excessive soil moisture on grass utilisation and the effect of deficit in soil moisture on grass growth are well known. However the effect of excess rainfall on the growth of sown grass is less clear and is usually not taken into account in grass growth models. This study was carried out to investigate the potential impact of excess moisture on perennial ryegrass growth in the field and to investigate the relative effect of soil moisture varying from deficit to excess …

Low abundance and poor persistence of legumes is a generalised problem in hill country pastures in New Zealand, even at adequate soil phosphorus levels (Woodfield & Caradus, 1996). Likely causes of low legume contents in swards include lack of soil moisture, high temperatures (Barker et al., 1993), frequency and intensity of defoliation (Suckling, 1975; (Lambert et al., 1982) and increased grass competition due to increasing fixed nitrogen in the soil (Lambert et al., 1982). On this later point there is anecdotal evidence that suppression of the grass component with herbicide will boost clover content, colloquially called 'chemical topping'.

Napier grass (Cenchrus purpureus Schumach L.) is an important perennial forage native to Africa and grown in many tropical and subtropical countries. It is considered as a short-term drought tolerant forage which is a useful trait in areas that are characterized by low precipitation during the dry season. To exploit the potential of this grass and identify water use efficient (WUE) genotypes, a field drought stress trial was conducted at Bishoftu, Ethiopia. Eighty-four Napier grass genotypes were planted in a p-rep design in four replications. The genotypes were evaluated for forage performance during the dry season of 2019 and …

Experiments were conducted within a long-term nitrogen (N) fertiliser experiment under grazing. The objective was to examine N response efficiencies (kg dry matter (DM)/kg N) and herbage crude protein (CP) content to fertiliser N applied under dry soil conditions (gravimetric soil moisture content of 17% at 10cm; soil field capacity = 38% and wilting point = 11%) during autumn (April 1999) and late spring (November 1999) in southeastern Australia. Visually, N treated plots were greener in colour than control (no N) plots. No differences were recorded in primary or residual DM yields, N response efficiencies, and pasture growth rates between …

Rainfall (R) falling on any vegetation can be partitioned in Stemflow (SF), Throughfall (TF) and Interception loss (I). Stemflow is that part of rainfall which flows down to the ground via leaves, stem, branches and trunk (above ground vegetative part). Throughfall is the part of rainfall which drips down through the canopy to the ground. Interception is the part of the rainfall after absorption by different parts of tree which remains with the above ground vegetative part and later on lost by the process of evaporation. Thus, SF and TF are combined termed as net rainfall and flow as runoff …

One of the main impediments in the way of improvement of livestock production is insufficiency of fodder. The gap between supply and demand would further aggravate due to increase in livestock population. In eastern India and Bengal delta land is usually devoted to fodder crops beyond monsoon when soil moisture becomes a limiting factor for crop production. Appropriate soil moisture conservation practices may reduce the evaporation loss and increase the yield. Among the different soil water conservation measures, mulching has gained popularity because it reduces the direct evaporation loss of soil water by restricting the transport of water vapour from …

Effect Of Soil Moisture Status And Animal Treading On N2O Emissions And The Effectiveness Of A Nitrification Inhibitor Mitigation Technology, H. J. Di, K. C. Cameron, B. Ball, A. Podolyan, Jizheng He
IGC Proceedings (1997-2023)
Nitrous oxide (N2O) is a potent greenhouse gas with a long-term global warming potential about 298 times that of carbon dioxide (CO2). In grazed grassland, most of the N2O is emitted from nitrogen (N) excreted by the grazing animal, particularly in the animal urine. When the soil is wet, such as that in winter grazing conditions, animal grazing can cause soil structural damage, leading to soil compaction. The combination of a wet soil plus soil compaction is particularly conducive for N2O production. A nitrification inhibitor technology using dicyandiamide (DCD) has been developed …
