Root biostimulant in spring vegetable crops

Bioestimuante radicular

Applying a root biostimulant in spring vegetables crops for a powerful development results in a pivotal factor to ensure an optimum yield.

Crops must cope with a wide range of unfavorable situations so as to achieve optimum performance. Together with pests and diseases, and within the context of climate change, there are more and more situations of environmental stress occurring. These factors lead to production decline, both in quality and quantity. Thus, regulating plant growth ends in a highly important factor, which will mark the productivity of crops.

In crops, a powerful starting is always synonymous with safe harvesting. Therefore, the treatments applied in initial stages play an essential role in the later development. With the calendar well into the month of May, the last frosts of spring have been left behind. The weeks that arrive ahead will take us into summer.

Thus, hot days with many hours of sunshine begin to become common, creating a favorable scenario to obtain the maximum yield in summer crops like tomato, pepper, eggplant, melon or watermelon. The cultivation of vegetables in spring has begun during winter months by preparing the seedbeds. Later, in spring, we proceed to field transplantation.

In southern regions like Almeria, this calendar is slightly modified when it comes to greenhouse plantations. Seedbeds have been prepared in July, and transplantation is delayed until the months of August-September.

Irrespective of the calendar, the application of a root biostimulant is well recommended within the first stages of cultivation. By using it, a broad, dense and branched root development is promoted in the plant.

A better plant development results in crops being more tolerant to the most unfavorable environmental conditions. Crops are also more capable of resisting disease entry. In addition, it allows better absorption of nutrients, so that apart from achieving better yields (and fewer losses), the quality of the crop will be higher.

Root biostimulant: growth and nutrient uptake

Seiland is a biostimulant to be applied at the time of transplantation, just within the first stage of cultivation in the field. The solution produced by Seipasa contains a mixture of microorganisms colonizing the ecological niche that roots occupy and creating a biological barrier that is beneficial for crops.

Seiland is high in organic matter. It provides carbon and nitrogen to the soil. These elements are needed for the installation and development of microorganisms. Its action allows to colonize the root area so as to protect it from being attack by pathogens.

The microorganisms of Seiland provide substances activating defense mechanisms, as well as elements and substances beneficial to plant development. The application of Seiland also allows to stimulate the activity of the microbial flora of the soil. Therefore, nutrients are more accessible to plants, allowing a more efficient use of fertilizers.

The application of a root biostimulant in spring vegetable crops is especially visible from initial stages. Not only does this process contribute to a correct plant development, but it also helps the plant to complete its cycle properly. It means not being conditioned by the different stresses in initial stages, when crops are more vulnerable.

Fertilizers for tomato fattening

Fertilizers for tomato fattening

 

Best fertilizers for tomato fattening contain organic matter, potassium, fulvic and humic acids, and microelements.

Achieving the highest harvest percentage with proper size and color is the goal of all farmers. This is very important to market the products. Hence the importance of assessing the application, at the appropriate time and following the needs of the plant, of fertilizers for tomato fattening and, where appropriate, specialized biostimulants.

When the fruit setting phase, the plant requires an extra contribution of potassium. Deficiency of this element can lead to an irregular maturation, preventing the full formation of the fruits in many cases.

Symptoms of potassium deficiency can be observed by small fruits with non-uniform coloration being produced, with yellow spots in areas that do not mature enough. It also leaves weak stalks, chlorosis and scorched edges on the leaves, poor resistance to pests and diseases, as well as increased susceptibility to frost and droughts.

Fertilizers for tomato fattening: potassium and much more

The relationship between potassium, fruit growth and maturation shows the importance of this macro-element in the quality of crop production. However, other factors must be taken into account to ensure the size, color and flavor of the tomato, without harming the characteristics of each variety.

Besides the need for a nutrient balance, with an adequate balance of other macro-elements and micro-elements such as Boron, Molybdenum, Calcium or Magnesium, environmental factors such as temperature must be taken into account. Between 24 and 28 degrees (Celsius) or solar lighting are  optimal for maturation. The characteristics of the substrate significantly influence the process, since this is the natural source of nutrients.

Fertilizers for tomato fattening: the importance of the substrate

The most demanding agricultural producers look beyond the specific application of mineral nutrition. They pefer to ensure not only the size of the fruits in that campaign, but also the richness of the soil that gives them greater guarantee of success for the next crops. What is key is to take advantage of all nutrients in the substrate while maintaining the balance of the substrate for short and long term benefit.

The most suitable tomato fattening fertilizers are those combinig organic matter with high content of potassium. Some very specialized references even contribute fulvic and humic acids, vitamins and microelements. This is the case of Terrasei Fruit, from SEIPASA.

The role of organic matter in tomato fattening fertilizers

Potassium fertilizers with high content of organic material such as Terrasei Fruit, significantly reduce potassium fixation inside the clays and its leaching loss in sandy soils. They increase both the concentration of potassium available and in solution in the soil. Its use favors the structure of the substrate, but also improves the absorption of potassium provided by conventional fertilizers.

Fulvic and humic acids contained in this reference are essential to regulate the physical and chemical properties of the soil and also to favor the development of beneficial microorganisms. This fertilizer has an immediate and slow release effect, helping to provide nutrients gradually.

Early maturation by applying fertilizers for tomato fattening

With the same conditions of temperature and illumination, it is possible to obtain a greater precocity and organoleptic quality in the process of maturation. This is because of fertilizers for tomato fattening. When it comes to Terrasei Fruit, results of the studies reveal considerable advance in maturation. As shown in figure 1 (corresponding to an experiment in which four applications of the product were carried out from fruit setting to harvesting) harvesting of the first fruits after maturation (days to first pick) was advanced 21 days.

Fertilizers for tomato fattening: performance, size and color

Apart from favoring fruit maturation, field studies confirm that Terrasei Fruit ensures high performance (see figure 2) and a marked improvement in size (see figure 3), color (see figure 4), plant growth, length root and sugar content. Additional test data can be found here.

Advantages of liquid format in tomato fattening fertilizers

Organo-mineral fertilizers in liquid form such as Terrasei Fruit reach deeper soil profile compared to solid organic matter.

Biostimulants for tomato maturation and fattening

Biostimulants result in a specialized option so as to induce maturation and fattening of fruits and, depending on the characteristics of the crop and needs, could be combined with fertilization.

A reference specially addressed to this purpose, foliar and root application, is Sweetsei. This is a biostimulant of rapid assimilation. Besides advancing maturation, it increases fruit size while achieving uniformity and excellent color. Furthermore, it obtains greater elasticity, hydration and firmness due to an organic polymer incorporated in its composition. In the same way, it improves fruit behavior in post-harvest and favors the formation of sugars, improving the index of Brix degrees.
