Hand coloured photoengraved print by Dorothy Blackham titled 'Ploughing'. The print depicts a man ploughing a field with a horse-drawn plough, there are trees and birds in the background. The text below the illustration is a poem by J.G. Whittier. The first two lines read "Drop thy still dews of quietness/ till all our strivings cease."

The plough is the vital, part of the ryot's equipment. Ploughing is the first and foremost operation in the preparation of the soil to develop tilth. This is just as true to-day as it ever was, despite the introduction of many other forms of tillage implements.

Ploughing and non-ploughing techniques
Soil and Tillage Research, 1991Abstract Operational factors influencing the performance of ploughing and non-ploughing techniques are discussed and ways through which performance can be improved are identified. With good implement adjustment and similar working depth ranges, the cost and output differences between the different tillage techniques are minimal, when the same final ...

Agronomic aspects of ploughing and non-ploughing
Soil and Tillage Research, 1991Abstract Ploughing is criticised because: (1) the rotational energy produced by the tractor favours the use of powered rotating tools; (2) erosion risks are greater on bare soil than under permanent cover; (3) in ploughed soil the more rapid decomposition of organic matter supposedly leads to poorer soil structures; (4) chemical weed control would ...

Power consumption at ploughing by share plough
1999Ploughing depth, plough construction and equipment, work method, smoothness of the working surfaces, soil and preceding crop are significant factors of energy consumption at ploughing by share plough. During the investigation it was determined that resistance to ploughing consuderably increases if ploughs are not equipped by coulters i.e.

Effects of a Plough Support Wheel During Ploughing
Journal of Agricultural Engineering Research, 1996When the plough support wheel is in use, the quality of the ploughing and the mobility of the tractor is improved significantly. With the support wheel, the tractor power lift functions better because it foresees changes in the ploughing depth and in the field profile.

Blackfriars, 1931
There is a tendency to set up mathematics, in its frigid detachment and unreality, as the very pattern of a science, and even of philosophy. Here St. Thomas’s terse Aristotelianism in mathematicis non est bonum is appropriate to show the indifference of our deepest desires to such an abstraction.

Current opinion in investigational drugs (London, England : 2000), 2001
Ezetimibe (Sch-58235) is a cholesterol absorption inhibitor being developed by Schering-Plough for the potential treatment of atherosclerosis and hypercholesterolemia. By January 2000, it was in phase III trials in the US [353762], [363364]. Schering-Plough is studying ezetimibe as a monotherapy for lowering lipid levels and, by February 2000, it was ...
