PHOSPHORUS: THE MASTER KEY TO PERMANENT AGRICULTURE · Hopkins, Cyril G. (Cyril George), 1866-1919 · 2003
... Though this is a very weak acid, its solvent action is very important. But, in addition to the various organic acids and carbonic acid, we have also to consider the formation of nitric acid ...
The acidity ranges from .4 to 2.3 per cent. The acidity is one of the most important factors in preventing the growth of bacteria and yeasts in the ketchup after being opened. In ...
... The acids most commonly used for this purpose are cream of tartar, acetic acid, vinegar, which has acetic acid for its basis, and lemon juice, which has citric acid for its basis. With each ...
The second step in vinegar making is the change of the alcohol of the hard cider into the acetic acid of the finished product. This is accomplished by the acetic acid germ, another microscopic ...
... We shall soon learn that the acetic acid of the vinegar is formed from this alcohol. Now, in order to obtain the maximum amount of acetic acid, it is necessary to have as much ...
"WITH TIME AND CARE AUSTRALIA OUGHT TO BE THE VINEYARD OF THE WORLD." · Muskett, Philip E., -1909 · 2003
Besides the water and the glucose, the must likewise contains quite an appreciable amount of those important bodies, the various acids. These consist of tartaric acid, so frequently met with all through the vegetable ...
... A good total acidity is 1.25%, figured as acetic acid. This figure includes both the acetic acidity of the vinegar and the natural acidity of the tomato. If a catsup is properly manufactured ...
... The acidity can hardly be due to uric acid, as the contents of the upper part of the intestine were often acid. In one case the contents of the gizzard were slightly acid, those ...
... In 1857, he bought 700 acres more at $50.00 per acre, and in 1859, he acquired 1500 acres of the Strawn estate at $30.00 per acre. In 1864, he secured 853 acres ...

VEGETABLE ACIDS.--Oxalic acid in particular is corrosive in its action when taken in concentrated solution, losing its corrosive effect and becoming irritant when more dilute. It also exerts a specific effect on the ...
The addition of some kind of an acetic acid starter, either as a pure culture of the acetic organism or as good vinegar, hastens the fermentation and reduces appreciably the time required for making ...
Acetic acid produced hardly any effect on his sand; and even hydrochloric, nitric and sulphuric acids, diluted as in the Pharmacopoeia, produced less effect than did the acids in the intestines of the worms ...
This done, we are now ready to introduce the acetic acid [Page 12] germs. This may be carried out in a number of different ways, but preferably by means of a pure culture of ...

AI-ORGANISED INDEX
measurement · m2, hectares, acres
Old books are in acres, new ones in hectares, and field maps in acres. Learn both. A hectare is about 2.5 acres, which is close enough for a rough job but not for a rent calculation.
AI-ORGANISED INDEX
kitchen · %
The acid does the preserving. If you cannot get a 5% vinegar, make a brine pickle instead. See Kraut And Kimchi.
AI-ORGANISED INDEX
agronomy · bushels/acre
For converting the old imperial yields into today's tonnes a hectare, and for reading the old books on the shelf. A bushel is a volume, so the weight depends on the crop.
AI-ORGANISED INDEX
chemistry · pH units
Soil, water, antacids and preserves. A change of one unit is ten times more or less acid, which is why a small pH change matters so much. See Soil Ph And Lime.
AI-ORGANISED INDEX
kitchen · g
Double acting powder works twice, once in the mix and once in the oven, so it is more forgiving. Do not mix baking powder and bicarbonate of soda together.
AI-ORGANISED INDEX
physics · newtons (N)
The force needed to move a mass. The tractor pulling a trailer, the ramp lifting a load, a horse pulling a plough. Double the mass and you double the force, for the same acceleration.
AI-ORGANISED INDEX
chemistry · %
How well a process actually ran. A lime neutralisation that only reaches 80% means you need more lime than the label says.
AI-ORGANISED INDEX
data · varies
Average feed analysis across different batches, average yield across fields of different sizes, average price across different volumes sold.
AI-ORGANISED INDEX
money · currency per hectare
The only way to compare two crops, or two fields, fairly. Divide the whole year's cost by the area, not just the variable bits.
AI-ORGANISED INDEX
data · %
For a sprayer that does not deliver its rated volume, a scale that reads light, or a soil test that is out by a tenth of a point. Know the error and you can correct for it.
AI-ORGANISED INDEX
chemistry · mol/L and litres
Every time you mix a concentrate with water, for a spray, a disinfectant or a test solution. Always add the concentrate to the water, never the other way round.
AI-ORGANISED INDEX
chemistry · pH units
How a milk, a must, or a soil stays at a steady pH while things are added to it. A brine is a buffer, and so is the lime in a soil.
AI-ORGANISED INDEX
chemistry · mol/L, mL
For working out the strength of a bought solution, and for checking a soil or water test against the method. The end point is the colour change, so get it right before you read the burette.
AI-ORGANISED INDEX
workshop · mm
Why a door jams in a wet winter, why a solid wooden worktop cups, and why a gate needs a gap. Plan for the movement.

AI-ORGANISED INDEX
electrical · ohms
Total opposition to alternating current in motors, pumps and long cable runs.
AI-ORGANISED INDEX

Checking a scale, a meter, a yield estimate or a mixing measurement.
AI-ORGANISED INDEX
finance · money
What regular savings or reinvested profits accumulate to over time.
AI-ORGANISED INDEX

Comparing costs or savings across years after inflation. A higher nominal figure may buy less.

More accurate earthwork volumes than end-area averaging, especially on long cuttings.
AI-ORGANISED INDEX

Compare a new freezer, a new shed or a flock of sheep against what they actually return each year.
AI-ORGANISED INDEX
measurement · km/h, m/s, mph
Work out how fast you are actually travelling. A hectare in a day, a round of the field in an afternoon, or whether a load of sheep will get to the market in time.
AI-ORGANISED INDEX
livestock · kg/day
The single number that tells you if a ration or a system is working. Weigh the animals, do it again in 30 days, and divide.
AI-ORGANISED INDEX
chemistry · mol, g
For making a solution of a known strength, for a lime neutralisation calculation, and for anything where the reaction has to be right rather than roughly right.
AI-ORGANISED INDEX
energy · V, A, ohm
The starting point for any electrical fault finding. If the voltage is right and the lamp is dim, the current is low, so the resistance is too high. See Electrical Fault Finding.
AI-ORGANISED INDEX
kitchen · per portion
For working out what to charge at a gate sale or a market stall, and for seeing which dish actually earns.
AI-ORGANISED INDEX
physics · N
Mass is how much there is, weight is how hard it presses. A sack of fertiliser has the same mass everywhere and a different weight on the moon. Lifting power is usually quoted in kilograms, which is really a mass in disguise.
AI-ORGANISED INDEX
workshop · teeth per inch
The difference between a saw that cuts along the grain and one that cuts across it. A rip saw has few deep teeth; a crosscut saw has many fine ones.
AI-ORGANISED INDEX
physics · Pa
The stiffness of a material. Steel is nearly twenty times stiffer than oak, which is why a steel frame sags less and lasts longer than a timber one of the same size.
AI-ORGANISED INDEX
livestock · kg
Measure around the chest just behind the front legs (heart girth) and from the point of shoulder to the pin bone (body length), both in centimetres. Square the girth, multiply by length, divide by 300. Best for cattle; less accurate for very fat or very thin stock.
