Where does this need come from? What are the significant benefits?

In fact, it has been proven, through analyses and scientific research, that the vegetative cycle of the plant does not end at the moment of harvest, but continues until the arrival of winter temperatures (below 10°C), just before winter dormancy.

Indeed, during this period of time, plants accumulate nutrients to be used the following spring during the vegetative growth phase.

More specifically, until the leaves completely fall, the plants absorb nutrients through intense root activity (fruit trees until the end of October and vines in November), which will constitute nutritional reserves for the next growing cycle.

To ensure good fruiting in the next growing year, the accumulation of sugars, amino acids and trace elements is very important, as a guarantee for good flower fertility. Another essential element is nitrogen, as from vegetative growth to flowering, the absorption of this element is moderate and the growth of shoots and flowering takes place at the expense of reserves. It is important to mention that the ideal period for carrying out autumn fertilization is between September and October, using fast-acting fertilizers.

The results that can be obtained from autumn fertilization (supported by many years of experiments) are a better vegetative-productive balance, increased flower fertility, increased production and finally a reduction in production rotation, a fundamental point – key to maintaining high profitability of orchards.

Another factor that should not be underestimated is temperature: temperatures in early autumn allow good absorption (the important thing is not to drop below 10-12 °C). The fertilization period can also vary depending on the crops and the region.

However, it is important not to confuse autumn fertilization with spring fertilization: they are complementary to each other, without one excluding the other. This must be taken into account in order not to exceed the doses of fertilizers provided annually.

Autumn fertilizers for use directly in the soil
TOP LINE

The recommended products are Top N 13-0-0 and Top 7-5-14: both of these products are part of a series with high nutritional efficiency and low environmental impact (suitable for use in organic farming as well).

The high nutritional efficiency is given by the differentiated release of nitrogen and other nutrients: the FCH (Fully Controlled Hydrolysis) technological process, on which the TOP series is based, contains organic carbon in a fully bioavailable form as well as the innovative APR (Rhizosphere Protein Activator) molecule. The product acts at soil level by activating the activity of microorganisms present in the soil and at root level, increasing the formation of active roots, improving the absorption of nutrients.

Autumn fertilizers for foliar applications
BORINC FAST

Provides crops with boron and zinc, two essential microelements for the development of flowers and fruits, for the metabolism of proteins, sugars and for the strengthening of plant tissues.
Post-harvest applications are recommended to increase the plant’s resistance to low winter temperatures and to ensure better vegetative growth the following spring.

FLORAL 20-20-20

Like all the preparations in the Floral Line series, it offers maximum efficiency in foliar nutrition and, in addition, the high purity of the nutrients it contains allows for quick and complete dissolution. Floral 20-20-20 allows the correct amount of fundamental nutrients to be administered to the plant, including microelements, to restore the natural nutrient reserve and for the plants to better cope with vegetative growth in the coming spring.

Strawberry

The establishment of new strawberry plants is in the spotlight this season. Its success depends largely on proper soil preparation and strengthening of the root system. The application of Top N, a slow-release nitrogen preparation, is an excellent choice for basic fertilization, offering the plants a stable and prolonged supply. At the same time, Betalga, with its rich combination of algae extracts, spectacularly supports root development and contributes to a healthy and dynamic start to the crop.

Citrus fruits

During October, special emphasis is placed on Calcium adequacy, protection from abiotic stress and enhancing fruit color. The application of formulations such as Calcium Fast, Calcisan, Calcisan Green and Neobit ensures effective coverage of Calcium needs, preventing apparent quality problems. At the same time, the use of Macys BC, a formulation with an extract of Macrocystis integrifolia, enhances the plant’s natural defense mechanisms against stress. Fruit color is substantially improved with the parallel use of Potassio 30, Floral K, CIFO KS 64 or the specialized CET 46 Green, which impart an intense and uniform color, enhancing the taste and commercial value of the fruit.

Cherry

In cherry, this period focuses on post-harvest nutrition, as the trees prepare for the following year. The application of Zinc Fast contributes to enhancing the differentiation of buds by providing Zinc, while the combination with Mikrom Borinc, which contains Boron and Zinc, further strengthens the nutrition of the plant. In addition, the use of potassium and phosphate preparations such as Floral K, Potassio 30, CIFO KS 64, Floral P and Foxter 520, completes the nutrition of the crop before entering dormancy.

Pomegranate

For pomegranate , October is crucial for strengthening the fruit with Calcium, especially in cases where applications have not been made in September. Formulations such as Calcisan, Calcisan Green, Calcium Fast and Neobit effectively cover the needs of the trees, preventing the Bitter Pit phenomenon. In red varieties, the use of CET 46 Green contributes significantly to strengthening the coloring, providing uniformity and intensity, elements that increase the commercial value of the fruit.

Olive

The olive tree enters the coloring stage, which imposes increased needs for Potassium. The application of the preparations Floral K, Potassio 30 and CIFO KS 64 is of crucial importance, especially in dry olive groves. At the same time, the use of Macys BC 28, rich in natural algae extracts, offers an anti-stress effect and enhances the resistance of the plants. In terms of plant protection, the appearance of gliospores after the first rains requires immediate prevention with the help of copper preparations such as Blok 5 and Sinergon Cu. Finally, in edible varieties, the application of CET 46 Green significantly improves the coloring, enhancing the commercial appeal of the fruit.

Kiwi

As kiwifruits approach ripening, the main priority is to improve the quality characteristics of the fruit without reducing its firmness. The combined use of CET 46 Green and Biolight enhances the flavor and increases Brix°, ensuring high quality production. The application of Macys BC 28 offers valuable anti-stress action and enhances the natural defense of plants against pathogens.

Stone fruit

Although the differentiation of buds in stone fruits has started since the summer, this process is completed in the fall. The application of Zinc Fast provides Zinc, a crucial element for the correct differentiation, while the reinforcement with Mikrom Borinc or the combination of Zinc Fast with Borfast, ensures the better movement of Zinc from the leaves to the buds, with the contribution of Boron.

Winter Grains

October marks the start of winter grain sowing. At this stage, adequate nitrogen is critical for good crop establishment, tillering and the formation of quality ears. Top N, with slow-release organic nitrogen, is an excellent choice for organic and conventional farming.

Leafy Vegetables

Leafy vegetables benefit significantly from foliar applications during this period. The application of Azomin, rich in organic matter, contributes to strengthening soil structure and improving nutrient uptake. To strengthen the leaf surface and activate photosynthetic activity, Sinergon 3000 offers impressive results.

Greenhouse Horticultural Products

In greenhouse crops that are either in the transplanting or fruit-setting phase, the choice of the appropriate formulations is crucial. Betalga ensures smooth establishment of the plants in the new environment, while formulations such as Plantonic, Sinergon 3000 and Cifalga offer support for fruit-setting and fruit development, both through root irrigation and foliar applications.

In conclusion:

October is an opportunity for interventions that will determine the success of the crop. Through targeted choices and the appropriate know-how, each producer can add value to their harvest and enhance the sustainability of the crop in a meaningful way.
