How to determine grams without fertilizer scales. How much urea is in a tablespoon, teaspoon, glass, matchbox (grams). how much fertilizer is in a teaspoon,...

Ay, what a topic! I won't pass by.

The problem raised by Tatyana is truly pressing. Electronic kitchen scales do not show tenths of grams; between adjacent values ​​of 1 and 2 grams the difference in weight is 100%.

A couple more ways to measure small amounts of dry fertilizer.

Volumetric weighing

With all the variety of thimbles, the average volume of a thimble has remained unchanged for centuries - about 2 milliliters:

Measuring the volume of a thimble

If you have some kind of non-standard thimble, then:

• set to zero
• pour 10 thimbles into a cup
• Divide the scale reading by 10 to get the volume of the thimble (1 milliliter of water = 1 gram of water).

If you don’t have scales on your household, fill a 100 or 500 gram jar with your thimble. And divide the volume by the number of thimble portions used. This will give you the volume of a non-standard thimble.

Or use a used syringe to draw in the water that fits into the thimble - the divisions on the syringe will show what volume it contains.

Theoretical rationale for volumetric weighing

It is necessary to make a reservation that not every fertilizer has an equality of 1 milliliter of volume to one gram of weight. Therefore, Tatyana indicated fertilizers for which this equality is observed.

Fertilizers often have a lower density than water. But for violets, some lack of fertilizer is not critical, especially taking into account the recommendations for violets to dilute standard fertilizers by half. Therefore, volumetric measurement of fertilizers is quite appropriate in caring for violets, even if the density of the fertilizer is unknown.

After using the thimble, be sure to rinse it, fertilizer dust may not be the best reagent for your finger.

Pirate way to determine small quantities

Place the contents of the fertilizer bag on a piece of paper. The weight is written on the bag. By eye, move some of the fertilizer to the side so that in a large pile there remains fertilizer to one of the powers of two (2, 4, 8, 16, 32, 64,... grams).

Divide the large pile in half. Divide each half in half again. Divide the quarters in half too. Eights are also halved. At some point you will end up with many, many small piles of fertilizer, each containing about 1 gram. Pack each pile in a small paper bag and use as needed for the health of your violets.

Using the same method, you can measure, for example, 1/8 of a gram from 1 gram of potent fertilizers.

Option. If you have a large bag of fertilizer and a kitchen scale, you can measure, for example, 16 grams and package it as suggested.

Historical excursion

In countries where there were many pirates at one time, there is still a running joke:

Question: How many pirates can there be on a pirate ship?

Answer: 2, 4, 8, 16, 32, 64, 128,... Otherwise, you will have to shoot the extra ones during a fair division of the spoils.

Jokes aside, the pirates were great at dividing their booty into any equal number of parts, and everyone considered the division fair.

For this there was a special way of sharing, which was called pirate. In the very in simple form(2 pirates) one pirate divides the booty as he sees fit into 2 equal parts. And the other chooses the part that seems larger to him. Questions about fairness do not arise for either side.

For a larger number of people, division follows a similar scheme in several stages - first they divide the spoils large groups pirates, then within the group the pirates are split into small groups and continue to divide small groups among themselves, and so on until the entire large pile of loot is divided between many pairs of pirates. Taking into account that the pirate life was short, everyone was in plain sight, and during the capture of ships, pirates often saved each other’s lives, they often trusted their pirate friends, who were better familiar with the value of the loot in the colonial markets, to divide/choose their share.

In English-speaking countries, the medieval “pirate” is still one of the most favorite masquerade images for children:

Measuring small amounts of liquid fertilizer

I will add that you can also conveniently measure liquid fertilizers from bottles with a syringe.

And with a pipette you can measure out a very small amount of fertilizer. Don't know how much one drop from your pipette weighs?

• place an empty cup on the kitchen scale
• set to zero
• pour 100 drops into a cup
• Divide the scale reading by 100 to get the volume of the droplet (1 milliliter of water = 1 gram of water).

Similarly, you can measure how much a droplet weighs from a jar of Corvalol and use it as a container for storing liquid fertilizer.

The sizes of droplets from different pipettes and different jars strongly depend on their parameters, so it is better not to use the data obtained for one pipette or jar for others.

If there are no scales at the dacha, any preparations and bulk substances can be measured in various containers, for example, soil and organic fertilizers in buckets, water and drops and glasses; it is also useful to know how many grams of fertilizer a matchbox, glass or spoon can hold.

Fertilizer weight measures

The error may be 2-3 g depending on the moisture content of the weighed fertilizer. Assuming this is better to take less than more! Don’t forget that too much fertilizer can cause harm – it can burn the roots or leaves. For mineral fertilizers It is better to purchase electronic kitchen scales. Their error is +/- 1 g. Well, in the meantime, use the table.

At the tip of a medium-width knife, place 0.25-0.5 grams of light powder or 1-2 grams of heavy powder.

A faceted glass holds 10 matchboxes of bulk substances.

How much water is in different containers

Water for various needs is used in gardening in large and small volumes, how much water different containers hold in grams.

Maybe someone at their dacha has pharmacy or regular scales, but I don’t. And I always fell into a stupor when I had to measure out a certain number of grams of fertilizer or pest control in order to prepare a solution. Until I came across a convenient table showing how many grams are in a spoon, teaspoon and table spoon, and how many grams are in a glass or matchbox. Now I can easily “weigh” the right amount of the most commonly used chemicals in the garden.

How much water is in a glass or spoon

Knowing how much water is in a glass, in a spoon, and how many spoons in a glass can also be very useful, since you often have to prepare small volumes of solutions for spraying garden crops.

• 1 teaspoon contains 5 grams of water or 100 drops;
• 1 tablespoon = 3 teaspoons (15 g);
• 1 faceted glass holds 13 tablespoons or 200 grams of water;
• 1 faceted glass with rim – 250 g of water

How many grams on the tip of a knife

On the tip of a regular pocket knife, place 1-2 g of heavy powder or 0.25-0.5 g of light powder.

When using fertilizers, it is necessary to measure 30 grams of nitroamophoska, or 15 grams of double superphosphate. But how much is it in volume?

how much fertilizer is in a teaspoon,...?

how much does fertilizer weigh in a 10 liter bucket?

How to calculate the amount of active substance and fertilizer.

In such cases, the following formula is applicable. Required quantity active substance (in our example this is 6 g of nitrogen) must be multiplied by 100 and divided by the percentage of nitrogen in the fertilizer. Let's take ammonium nitrate as an example. The percentage of nitrogen in it is 34%. Let's do the calculation:

6g × 100 = 600g

600g: 34 = 17.65, well, that’s about 18 grams. This means that in order for the earth to receive 6 g of nitrogen per 1 square meter, we need to take 18 grams of ammonium nitrate, and this can easily fit into a salt spoon (table above).

Let’s calculate as an example: per 3 square meters you need to add 8 grams of phosphorus. We have double superphosphate, the percentage of active phosphorus in it is 40%. We count:

8g × 100= 800g

800g: 40% = 20g. 20 grams of double superphosphate is a matchbox (table above).

There are quite a lot of fertilizers for feeding flowers and plants. They are available in liquid and powder form. And the instructions usually indicate how much fertilizer should be taken for a certain volume of water. But we all have different volumes of water for irrigation, the capacity of watering cans and bottles. For example, I water plants from one and a half liter plastic bottles, my friend uses five-liter and two-liter ones - it’s more convenient for her. Liquid fertilizers are easier to measure and calculate for the required amount of water, but powdered fertilizers (usually fine-crystalline powder) are more difficult. The point is that electronic scales with an accuracy of 1 g, not everyone has it. The concept of a “topped tablespoon” is also very subjective. And being too clever with fertilizers, pouring them “by eye”, is very dangerous for the health of plants.

Therefore, I will try to tell you how I calculate the doses of fertilizers for my flowers.

My most popular fertilizer is “Fertika Lux” - a pink, fine-crystalline powder, quite hygroscopic. Sold in bags weighing 20 g. According to the manufacturer, this is one tablespoon. Let me clarify, if you pour the contents of the bag into a tablespoon, it will be a heaped tablespoon.

20 g of fertilizer (1 sachet) Fertika Lux are designed for 10 liters of water. My flowers don’t drink that much at a time, and not all of them need to be fed with this fertilizer, so I dilute 1.5 liters of solution.

First, I pour all the fertilizer into a measuring cup to approximately know its volume. It is about 22 ml.

To measure fertilizers more accurately, I have a 20 ml syringe with the front wall and tip cut off.

I pour the fertilizer into the syringe, quite tightly, I have to press it lightly with a stick, but without force. The capacity of the syringe is exactly the required 22 ml.

I make a simple calculation: 22 ml of fertilizer is calculated for 1 liter of water, respectively, 3.3 ml of fertilizer is needed for 1.5 liters of water. But, I take strictly 3 ml - it’s better to have too little than too much.

And now I pour the resulting handful of fertilizer into a teaspoon (it turned out to be incomplete and without a slide), which I will use exclusively for chemicals. You can use any medicine measuring spoon. The more accurately the spoon size fits, the better.

In exactly the same way, you can calculate any other powdered or crystalline fertilizer for any volume of water. The main thing to remember is that the solution with fertilizer must stand for a while (about 1 hour) so that the crystals are completely dissolved; it is better to shake it periodically. Well, the most basic rules for fertilizing plants: you cannot water the fertilizer solution on dry soil, you cannot feed sick and weakened plants, as well as those that are dormant. The doses of fertilizing in universal fertilizers are usually averaged; for some plants you need to take a lower concentration of fertilizer (half or a quarter), so carefully read the recommendations for caring for plants. This primarily applies to bromeliads, ferns, orchids and some other flowers.
