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.
Image comparing the hectare (the small blue area at lower left) to other units. The entire yellow square is one square mile.. The hectare (/ ˈ h ɛ k t ɛər,-t ɑːr /; SI symbol: ha) is a non-SI metric unit of area equal to a square with 100-metre sides (1 hm 2), that is, 10,000 square metres (10,000 m 2), and is primarily used in the measurement of land.
A Morgen (Mg) is a historical, but still occasionally used, German unit of area used in agriculture. [1] Officially, it is no longer in use, but rather the hectare. [1] While today it is approximately equivalent to the Prussian morgen, measuring 25 ares or 2,500 square meters, its area once ranged from 1,906 to 11,780 square meters, but usually between ¼ and ½ hectare.

The idea for the Hands Free Hectare project was conceived in 2015 by two staff working in the Engineering Department at Harper Adams University, Kit Franklin and Jonathan Gill, who were frustrated by the pace and limited scope of academic developments in the area of field agricultural automation/robotics that they believed had become stagnant [1] when compared to tech sectors such as UAVs.
Free range meat chickens seek shade on a U.S. farm. In poultry-keeping, "free range" is widely confused with yarding , which means keeping poultry in fenced yards. Yarding, as well as floorless portable chicken pens (" chicken tractors ") may have some of the benefits of free-range livestock but, in reality, the methods have little in common ...
The systematic layout planning (SLP) - also referred to as site layout planning [1] - is a tool used to arrange a workplace in a plant by locating areas with high frequency and logical relationships close to each other. [2] The process permits the quickest material flow in processing the product at the lowest cost and least amount of handling ...
One acre equals 1 ⁄ 640 (0.0015625) square mile, 4,840 square yards, 43,560 square feet, [2] or about 4,047 square metres (0.4047 hectares) (see below).While all modern variants of the acre contain 4,840 square yards, there are alternative definitions of a yard, so the exact size of an acre depends upon the particular yard on which it is based.
[4] [5] The goal of precision agriculture research is to define a decision support system for whole farm management with the goal of optimizing returns on inputs while preserving resources. [6] [7] Among these many approaches is a phytogeomorphological approach which ties multi-year crop growth stability/characteristics to topological terrain ...
