Who said that a good fertilizer can not do at home ??


Here are some tips on how to fertilize your potatoes and keep the soil fertile without the use of chemical fertilizers.
If you think it sucks .... You will find that is a lot less crap of what you buy today. 🙂

First you must know one thing.

The basic nutrient for potatoes, are abounded amount of Nitrogen and Potassium (and to a lesser extent the other elements that still should not be overlooked)

Nitrogen allows a luxuriant growth of leaves, will make a beautiful green and the plant will grow healthy and strong.

It 'important especially during growth and much less later.

A deficiency will grow stunted plants with foliar chlorosis.

Potassium instead is the substance that allows a luxuriant growth of fruit (in our case tubers), and gives it flavor, but be warned that an excess can grow big fruit and "doped" but with little flavor.

A shortage instead grow small fruits.

Given that (as we said before) we want to try to grow them organically, we will proceed with the following "self-made" fertilizer.

Note: In the preparation of the following fertilizer, are included "human" waste products such as urine.

* For those are squeamish about the use of urine remember that in the products that we are usually in supermarkets are present:
Fungicides, Anti-sprouting, insecticides, antibacterials, Herbicides, Fertilizers Chemicals, Hormones, Pesticides.
Everything is picked unripe and matured in rooms with ripening gas.

Instead urine contains UREA, which -for your information- is the main constituent of many fertilizers.
It in a short time is attacked by bacteria naturally present in the soil and transformed first into ammonia and ammonium salts and then into nitrates and nitrites which (latter) constitute the basic food for any plant.
Moreover this process is not immediate, it is thus to create in the soil a "stock" of urea and ammonia salts that provide consistently (coming slowly deteriorated by the bacteria) nutrients for plants and effectively act as a slow-release fertilizer.

Manure N° I

  • A bucket, 20/50 L or even a bin
  • Your Urine
  • The ashes of the fireplace

To dilute all use a bit of ground but not too much and if you can keep the bin open in a cool place, not in direct sunlight.
This mixture provides excellent amounts of nitrogen, phosphorus and potassium, which are key elements for the potato plant.
Remember that the mixture is better to be always moist (even extra-wet with liters of urine is fine, but not dry), so remember to urinate into the bucket and in the meantime if you have ash available put it inside.
The ash is crucial, and it is even better to burn all the slow degradation remains products from the house as a crustacean shells, bones, dried fruit shells, not too wet skins (orange and co.), Egg shells ..... etc ... (organic materials of course, NOT plastic, newspapers, wood treated with paints and glues, etc ...).
Do not worry about any larvae or insects that inevitably end up in, will help to "work it" and when they die they too will become manure.

The ideal is to use it when it is ripe, then after about a month (if you pass more time should be fine anyway, but I'd say at most one year).
IF AND ONLY IF you are going to do it too mature for at least one month you can use droppings, but remember to mix everything well so they are torn to pieces.

If at the end of the month the compound will be a kind of compost or liquid depends on the amount of material added by you.

Either way you'll have a too powerful fertilizer for the plant, which if used directly on the same would kill her, so you have to dilute it by 1/10 or 1/20 depending on the fertility of your soil.

If you do not want to follow the procedure described above, directly dilute your urine just made 1/20, and wet the plants and that's okay. Or follow this other procedure below !!

Super Fertilizer for Potatoes

The above is a very good fertilizer but needs space and time to be prepared.
If you lack the latter you can prepare this other fertilizer that brings all the micro and macro elements they need plants.

The following fertilizer is used towards the end of the first crop and throughout the second crop.

Here's how to prepare it:
Take a bottle of vinegar to 1 L and a bowl / pan.
Put about 5 tablespoons of potassium bicarbonate (found at about 4 € / Kg on the internet) in the bowl / pot, and then slowly started to add vinegar.
It will do a great deal of foam (which is why you need a bowl, if done in the bottle come out) and slowly reacting and foaming, add vinegar.
When you have poured almost any vinegar (keep one finger in the bottle for later) with a teaspoon still slowly add the potassium bicarbonate until you see that the solution no longer fizzes.
Now put the last dash of vinegar that you had kept aside.

The solution obtained will be of potassium acetate.
E' importante perchè la pianta di patate ha un dannato bisogno di potassio, e anche se il terreno è ben concimato potrebbe non essere sufficiente.
The choice of producing the fertilizer by myself derives from the fact that on the market there are chlorides and sulphates of potassium, but you know how ....given that I have to eat, and since I am chemist I decided to create something that is a bit more healthy than chlorine and sulfur.

Back to the subject: The solution is very concentrated !!
Then in a watering can of about 5 liters, put in a glass of this solution (advanced solution we can keep for successive times) and a lovely urine! (Never fails !! 😀 )
At this point we will have a fertilizer that provides excellent amounts of nitrogen, potassium plus other micro and macro-elements, essential for our potatoes ..... and if advancing is fine for the other plants (This fertilizer, however, which is diluted and mixed with urine if advances, use it where you want, but do not keep aside)

Nature is fantastic is not it?
