This book covers the subject of grasslands used for grazing livestock. Grasslands can be split into improved and unimproved pastures (also a sub-set of rangelands). Land used for livestock industries occupy 70% agricultural land and about 40% of total land and produce 40% of agricultural gross domestic product (FAO, 2005; Steinfeld et al., 2006). Increasing populations and incomes, coupled with a change in diets and urbanisation in the developing world, is enhancing demand for pasture-based products (Devine, 2003; Schmidhuber and Shetty, 2005). For example, milk and meat production is predicted to double to just over 1 billion tonnes of milk and 465 million tonnes of meat by 2050 (Steinfeld et al., 2006). To meet these demands most effort will go into intensification of improved pastures, which translates into high stocking densities supported by large inputs of fertilisers, feed supplements and energy.
In addition to affecting the total P concentration in the faeces of dairy cattle, excess dietary P increases the water ... Desktop analyses indicate that the costs of construction and use of winter feed-pads may be compensated for by a ...
Animal Agriculture Impacts on Water Quality in California
Foraging decisions are likely to result in nutritional benefits with low probability of toxic or poor-quality plant material. ... Horse-sick pasture occurs on relatively small pastures with high stocking rates and long grazing periods.
Soil Processes and Water Quality examines principles and practices that minimize the risks of water pollution while enhancing agricultural intensification and productivity.
This handy guide is a primer for consultants, local agencies, and lending institutions that summarizes practical approaches and technologies that have been implemented by progressive dairy producers to protect surface and groundwater ...
Focusing on the different types of grassland farming and their impact on the environment, this book addresses issues facing environmental quality, namely soil, water and air quality and socioeconomic impacts.
This book is an essential guide for ruminant farmers who want to be able to create grazing systems that meet the needs of their livestock, pasture plants, soils, and the larger ecosystem.
Environmental Toxicology provides a detailed, comprehensive introduction to this key area of sustainability and public health research.
Cool-season perennial legumes: white clover, trefoil, and strawberry clover Legumes are sometimes included in pasture seed mixes because they are palatable and high in protein and they have the ability to fix atmospheric nitrogen.
