Deer and many goats can easily jump an ordinary agricultural fence, and so special fencing is needed for farming goats or deer, or to keep wild deer out of farmland and gardens. Deer fence is often made of lightweight woven wire netting nearly 2 metres (6 feet 7 inches) high on lightweight posts, otherwise made like an ordinary woven wire fence.
Keyline design is a system of principles and techniques of developing rural and urban landscapes to optimize use of their water resources. Australian farmer and engineer P. A. Yeomans invented and developed Keyline design in his books The Keyline Plan, The Challenge of Landscape, Water For Every Farm, and The City Forest.
A "stun–lethal" fence may also consist of two fences; one set of wires forming a conventional pulsed DC non-lethal fence, the second set (interleaved with the first) forming a 6.6 kV AC lethal fence, energized when the DC fence detects an intruder. Alternatively it may consist of a single, AC or pulsed DC fence capable of running in "safe ...
The Domesday Book of 1086 recorded at least 12% of people as free, 30% as serfs, 35% as servient bordars and cottars, and 9% as slaves. [5] The history of English land law can be traced into Roman times, and through the Dark Ages under Saxon monarchs where, as for most of human history, land was the dominant source of social wealth.
Using the achievements of the exact sciences to solve major problems in agriculture, agrophysics involves the study of materials and processes occurring in the production and processing of agricultural crops, with particular emphasis on the condition of the environment and the quality of farming materials and food production.
Two geofences defined in a GPS application. A geofence is a virtual perimeter for a real-world geographic area. [1] A geofence can be dynamically generated (as in a radius around a point location) or match a predefined set of boundaries (such as school zones or neighborhood boundaries).

Widely regarded as the leading practitioner of the second-generation of natural farmers, Yoshikazu Kawaguchi is the instigator of Akame Natural Farm School, and a related network of volunteer-based "no-tuition" natural farming schools in Japan that numbers 40 locations and more than 900 concurrent students.

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.
