Intensive Tomato Cultivation Technology: Fertilization Calendar and Agronomist Tips

To achieve high tomato yields, it is important to strictly adhere to the schedule for applying macro and microelements, with particular attention to their balance. During the stage of green mass growth, the crop primarily requires nitrogen fertilizers, while during the periods of budding and ripening, the focus shifts to phosphorus and potassium.

Excessive nitrogen can provoke excessive stem growth, preventing the plant from forming fruit set. This condition is referred to as “fatty growth,” and it negatively impacts future yields.

Balanced Nutrition: Root and Foliar Fertilization

To effectively provide tomatoes with nutrients, it is advisable to combine root fertilization with foliar spraying. Foliar feeding ensures rapid uptake of microelements, which is especially relevant during droughts when nutrient absorption from the soil is hindered. To improve the taste and density of tomatoes, experienced agronomists recommend applying boron and magnesium during the mass flowering phase.

Fertilization Calendar for Tomatoes

1. Start (10-14 days after planting): use nitrogen-containing complexes to stimulate active plant growth.
2. Budding: switch to phosphorus fertilizers that promote root system strengthening and bud formation.
3. Flowering: conduct foliar feeding with boric acid to maintain fruit set and prevent drop.
4. Fruiting: apply potassium fertilizers to increase sugar content in the fruits and improve their storage qualities.

Tip for Agronomists: When selecting seeds, pay attention to the germination energy indicator. The optimal soil for tomatoes should have neutral acidity (pH 6.0–6.7). Before the first fertilization, ensure that the plant has completed its adaptation period and shows no signs of wilting.
