Fertilizers for tomatoes: Nutritional values

What nutrients are needed to meet the needs of tomato plants. Soil, soil and fertilizer to have healthy and resistant plants with large, sweet and red tomatoes.


Similar to what happens to humans, the vegetable kingdom may also suffer from nutritional deficiencies. Poor soil of certain micronutrients can predispose tomato plants to a large number of diseases. Plants that grow on poor soil tend to be more fragile.
Fertilize tomatoes, such as nutrient
For humans, micronutrients are iron, calcium, phosphorus, vitamins and other mineral salts. For tomato plants the micronutrients indispensable to the growth and optimal development of fruits are:
Copper (Cu)
Manganese (Mn)
Ferro (Fe)
Zinc (Zn)
Macronutrients, for humans, are proteins, lipids and carbohydrates. For tomato plants, however, we have:
Azoto (N)
Calcium (Ca)
Sulfur (S)
Magnesium (Mg)
Potassium (K)
Phosphorus (P)
This means that a good tomato fertilizer must, in the right proportions, all these elements or in any case go to compensate for the shortcomings of our soil.
Zinc, sulfur, iron and copper act as “growth activators” and generally a deficiency is felt only in the early stages of plant growth. If your tomato plant (grown in pots or in the garden) has already grown, it can withstand these shortcomings.
Tomato fertilizers
Plants can assimilate nutrients through the root system. Pay close attention: No fertilizer for tomatoes is effective if the plant is not well irrigated. Water is the medium through which plants can absorb the nutrients present in the soil.
In the article how to irrigate tomatoes I have already explained the consequences of excess water or irrigation scarcity. Make your evaluations and give water taking into account the real water needs of plants and not your appointments! Plants should not be irrigated only when you have time … the tomato does not need a lot of water, but requires irrigation to be constant without water stress.
If you do not pay attention to doing the right rotations in the orchard, cultivation after cultivation, the ground will tend to deplete. It is in this context that tomato-specific fertilizers become precious. On the market you can find many products, all more or less valid.
On this page I suggest you an excellent tomato fertilizer which I have been testing for several years now. I have always been fond of tomato varieties such as dairy, yellow tomato of Vesuvius, oxen heart, Sorrento tomato and sweet cherry tomato. These are varieties that give the best for their sweet taste and proper fertilization helps to enhance the flavor of tomato. I use it for these cultivars, but all the fertilizers you find on the market can be used for any variety of tomatoes.
The tomato fertilizer I use so much is called Maxicrop and the one-kg package is on Amazon for a price of 11.76 euro’s with free shipping charges.
In detail, the formulation brings to the ground the great part of the nutrients needed for the optimal development of tomato plants and especially fruit production. For completeness I point out the “hot spots” of the composition:
Azoto (8%)
Phosphorus (5%)
Potassium (6%)
Football (15%)
Manganese (5%)
Magnesium (6.5%)
The elements mentioned are listed in the form of oxides and are of natural origin. For this reason fertilizer is also indicated in the biological method.
For all the information refer to the product sheet: Maxicrop natural fertilizer.
Feel free to make your evaluations before buying, the important thing is that when choosing a fertilizer for tomatoes, the same nutrients are included, though they are present in slightly different percentages (each manufacturer has its own formulation).
How to fertilize tomatoes in pots or in the garden
Doses vary according to the chosen fertilizer. If you have chosen the fertilizer I have reported to you, you will need:
To fertilize tomatoes in pots
Add a teaspoon of the product (about 2 grams) to the jar. The dose is indicated for 30 cm pots. If you are cultivating tomatoes in a larger planter, increase the doses in proportion (for example, 4 grams for 60 cm, 6 grams for 80 cm crates …).
To fertilize tomatoes in the garden
Distribute 2 tablespoons of product (about 20 grams) per square meter of cultivated area. In practice, with 1 kg we managed to irrigate 50 square meters of field cultivated with tomatoes.
To ensure an excellent release, after distributing tomato fertilizer, remember to sprinkle the surface.
