English

Tomatoes ( Solanum lycopersicum L.) are a species of herbaceous plants of the solanum genus belonging to the Solanaceae family. They are very demanding in terms of climate. They are adapted to sandy loam, well drained and deep soils. In their early stages of development, they are a sensitive to competition from weeds, especially in organic farming.

Our solutions

The minimum return planting time for a tomato in a rotation is 3 years.

It is recommended to plant tomatoes after leafy vegetables such as salads, chard or spinach, which do not deplete the soil.

La tomate trouvera aussi sa place après un engrais vert, ou une période de jachère. Il est crucial d’éloigner les pommes de terre, sujettes comme la tomate au redoutable mildiou.

La carotte n’apprécie pas particulièrement les reliquats azotés importants. Les précédents défavorables sont donc les légumineuses pures (risques également de transmission des nématodes), les prairies de longue durée ou les betteraves.

Absorption curve of the major elements in tomatoes

Tomatoes are extremely demanding in nutrients, especially nitrogen, potassium, phosphorus and calcium.

Magnesium is an element to be monitored for its antagonistic effect on potash.

For good crop development, secondary elements such as boron, zinc, copper, iron and manganese must also be watched.

Comments on trace elements:

  • magnesium deficiency: leaf yellowing between the ribs.
  • Blossom end rot caused by poor migration of calcium in the plant and irregular watering.

Symptom: rotting base of the fruit, depending on weather conditions.

Remedy: liming in the case of soil acidity.

Adapt the water supply depending on the climate and avoid excessive transpiration. Remove leaves to adapt to the fruit load and reduce the leaf/fruit ratio.

  • In the 5 or 6 bunch stage, the application of leaf or complete liquid fertiliser may be useful in the case of deficiencies, to maintain strong plants


Our solutions for organic farming

Period of application:
Before sowing

Objective: improving added organic matter and the soil for higher productivity

  • Improving your soil and organic inputs (better return on investment)
  • Improving the availability of elements for more growth and yield (calibre and conservation)
  • Responding to rapid requirements and reducing losses due to short cycles

In addition, our various media will also provide calcium and potassium, essential for the migration of sugar and protein to ensure the calibre and quality of the vegetable, etc…

+

Period of application:
Before sowing

Objective: stimulating the growth of crops for better quality

  • Stimulating root growth
  • Increasing soil fertility by providing organic elements (NPK)
  • Improving nutrient absorption

In addition, our various media will provide, for example, potassium, essential for the migration of sugar and protein to optimise the calibre and quality of the vegetable, etc.

+

Period of application:
On sowing

Objective: strong start-up, root growth and stress resistance

  • Good implantation to close the row rapidly: competition from weeds
  • Stimulating root development for more exploration and yield
  • Improving stress tolerance for improved yield (quality)

In addition, our various media will also provide boron and potassium, essential for the migration of sugars and proteins to ensure the calibre and quality of the vegetable, etc.
