A pasture wedge graph or feed wedge is a farm management tool used by dairy farmers for the purposes of managing pasture. [ 1 ] [ 2 ] [ 3 ] It takes the form of a bar graph , [ 4 ] that shows the amount of feed available in a pasture over time, and is therefore shaped as a declining wedge.
Diagram of rotational grazing, showing the use of paddocks, each providing food and water for the livestock for a chosen period. In agriculture, rotational grazing, as opposed to continuous grazing, describes many systems of pasturing, whereby livestock are moved to portions of the pasture, called paddocks, while the other portions rest.

Dairy cattle grazing in Germany. In agriculture, grazing is a method of animal husbandry whereby domestic livestock are allowed outdoors to free range (roam around) and consume wild vegetations in order to convert the otherwise indigestible (by human gut) cellulose within grass and other forages into meat, milk, wool and other animal products, often on land that is unsuitable for arable farming.
A four-ox-team plough, circa 1330. The ploughman is using a mouldboard plough to cut through the heavy soils. A team could plough about one acre (0.4 ha) per day. The typical planting scheme in a three-field system was that barley, oats, or legumes would be planted in one field in spring, wheat or rye in the second field in the fall and the third field would be left fallow.
In an economically optimum forest rotation analysis, the decision regarding optimum rotation age is undertake by calculating the maximum net present value. It can be shown as follows: NPV and its relationship with rotation age and revenue. Revenue (R) = Volume × Price; Cost (C) = Cost of harvesting + handling. Hence, Profit = Revenue − Cost.
Alley cropping of maize and sweet chestnut, Dordogne, France Maize grown under Faidherbia albida and Borassus akeassii near Banfora, Burkina Faso. Agroforestry (also known as agro-sylviculture or forest farming) is a land use management system that integrates trees with crops or pasture.
Crop rotation is the practice of growing a series of different types of crops in the same area across a sequence of growing seasons. This practice reduces the reliance of crops on one set of nutrients, pest and weed pressure, along with the probability of developing resistant pests and weeds.
Continuous grazing by sheep or cattle is a widespread extensive farming system, with low inputs and outputs.. Extensive farming most commonly means raising sheep and cattle in areas with low agricultural productivity, but includes large-scale growing of wheat, barley, cooking oils and other grain crops in areas like the Murray-Darling Basin in Australia.
