Plowing and How It’s Judged
A lesson on judging competitive plowing and how Judges keep score.
What is Plowing?
The main purpose of plowing is to eliminate weeds and most of all the residues from the previous crop.
Definitions:
- An implement used to cute, lift, and turn over soil especially in preparing a seedbed.
- To turn, break up or work with a plow.
- To make (something, such as a furrow) with a plow.
- To cut into, open or make furrows or ridges in with or as if with a plow
For a thousand a years, plowing has been one of the main soil preparation methods.
Plowing Terminology
- The Plow – a farm implement used for cutting the soil and turning it over. The plow was the first tool to unlock the fertility of the earth.
- Furrow – the long narrow ribbon of soil which is cut off by the plow and turned over.
- Coulter – a sharp pointed knife or rolling disk which cuts the soil vertically.
- Share – (or plowshare) – a sharp pointed knife which cuts flat underneath the ground, loosening the soil cut by the coulter.
- Mouldboard – a curved blade which pushes the slice of earth to the side and turns it upside down. This slice of earth is called the furrow.
- Crown – consists of three trips to the other end of the plow and back (rounds). In horse plowing the results is 6 furrows, in tractor classes 12 furrows.
- Body of the Land – Upon completion of the crown, the contestant turns to the left and plows the strip between his crown and the neighbours.
- Finish – The last few furrows.

Definition of a Judge
- A person appointed to determine the result of a contest or competition
- A person who is able and qualified to give an opinion
- To form an opinion or conclusion about something
- To appraise critically
A person who by observing the land plowed, will in an unbiased and fair manor, judge a class of competitors in the proper order from 1st to last place using an IPM scorecard.

Match Plowing Scorecard & Its Five Categories

This is a systematic approach which has provided a tool for consistent scoring across many types of plowing.
- Horse walking and sulky plows
- Antique drag and hydraulic plows
- Conventional and Reversible plows (slight variation)
This system works for a beginner class at a local match up to the Canadian Championship Plowing competition.
All Attributes Scored Out of 10
Each and every column on the score sheet is out of 10:
- Makes for an easier way to think about scoring a land
- It becomes a mindset of 10โs
- How do we learn to come up with the numbers?
- Mentoring, training, Judges School or meetings, experience
When Judges look at plowing we may ask ourselves when determining what number to write down:
- Is it perfect?
- How can it be better or improved on?
- Did they do half a job?
- How low do we go on poor plowing?
- What number do we assign that attribute?
1 – SPLIT

- Straightness: 10 Points
- Cut & Uniformity: 10 Points

Open Split:
The strip to be well cut through so that no land is left uncut.
One round will be permitted in making opening split before judging.
All sod, weeds, etc., cut so that no uncut area remains under crown furrows


Faults observed:
- Centre furrow starts out small, gets larger by second arrow.
- Front furrows are more uniform!

This split will be scored low in cut and uniformity:
- Uncut grass or roots will lower the score on Cut & Uniformity.
- Uneven or lack of furrows will also lower the score on Cut & Uniformity

The split should have no grass or stubble anywhere inside of the split, either loose or still rooted in the soil.

Straightness is Important

2 – CROWN

Straightness | Closeness & Conformity | Burying Grass & Stubble | Soil Available
- 10 points each for a total of 40 points.
- Horses โ 6 rounds;
- Two Furrow plow โ 4 heavy rounds
- Three Furrow and larger plow โ 3 heavy rounds

Closeness & Conformity:
Front two furrows must meet and close so there is no open area between them.
Conformity means that each furrow in the land looks the same side by side.
All furrows should appear to have the same depth and width, and blend in well with
the other plowing.
You should be able to lay a plowing stake over a crown and all the top edges touch it.

Closeness & Conformity:
โ Do the front two furrows conform with the other furrows?
โ They appear a little wider and flatter than the next furrows.
Burying Grass and Stubble:
โ Nothing visible in this picture
Soil available:
โ Proper depth, and body to make enough soil available that if a set of harrows were taken across on a 30 degree angle, would create a level seed bed.

Closeness & Conformity:
โ 1st two furrows are closed in but are too high.
โ 2nd furrows on each side are too low.
Soil available:
โ Not as much soil either side of 1st two furrows.
โ Plowing somewhat flat looking without enough soil to make a good seedbed.

What faults do you see here?
Open crowns, wheel marks, furrows not matching, no body to furrows.
- This lowers score in Closeness & Conformity, Burying Grass & Stubble, and Soil Available.
3 – GENERAL WORK
Covering Grass | Closeness & Packing (no holes) | Firmness | Soil Available
- 10 points each for a total of 40 points.
This includes the entire land from Crown to Finish including the cast off.

GENERAL WORK is judged by walking across the land.


Covering Grass and Stubble
All grass, stubble and weeds must be completely buried.
Closeness & Packing (no holes)
The furrows should be well packed and closed with no openings between furrows.
Firmness
The furrows should be firm against one
another so that they do not break down or collapse.
Soil available
Proper depth, and body to make enough soil available that if a set of harrows were taken across on a 30 degree angle, would create a level seed bed.

4 – GENERAL APPEARANCE

Includes all furrows plowed.
Straightness | Conformity | Distinctness of Furrow | Uniformity & Shape of Furrow | Shape of Land | Ins & Outs
- 10 points each for a total of 60 points.



Shape of Land:

The proper relationship of crown to body of land to finish.
- A level crown with the balance of the land.
- Problems earlier in lands can lose you points again in Shape of Land.
- Good crowns, plowing and finishes will gain points in Shape of Land.
Ins & Outs:

All soil inside the scratch furrows should be turned with a minimum amount of headland being disturbed by the plow.
- The plow should be to plow depth as quickly as possible.
- There are 10 points for Ins & Outs.
- Both ends of field are looked at for scoring.
5 – FINISH

Straightness | Grass & Neatness | Shallowness & Narrowness | Soil Available
- 10 points each for a total of 40 points.

Includes the last 12 furrows (6 furrows on the throw out side of the finish and 5 furrows and the sole furrow on the crown side.
There is a misconception that it is only the last round of the plow.

Straightness:
Not only must the furrows be straight, they must be parallel.
Note that the tire track crosses over 1 complete furrow instead of staying true all the way across the field.
This lowers the score for straightness.

Grass & Neatness
Finish should be free from loose soil, weeds, etc.
Shallowness & Narrowness:
Depth should not exceed the average depth of plowing in the field.
The final or sole furrow should be at the same height as other furrows.
Soil Available:
Is there enough soil available to fill in the finish?
Is the tire track up or looks like another finish?
