Achieving high and high-quality yields in field crops requires the application of crystal and foliar fertilizers.
In order to ensure high yields of cultivated crops, it is necessary to pay attention to the controlled addition of fertilizers based on the needs of the given crops and soil analysis.
Easily accessible and necessary elements in the soil are: nitrogen, phosphorus and potassium. In addition to them, calcium, magnesium and sulfur, which belong to the macro-micro elements. Finally, we should not neglect microelements: iron, manganese, zinc, copper, molybdenum and boron. There are enough of these elements in production that is not intensive in the soil, but in more intensive production, such as vegetable production, they may be lacking, so we recommend the use of specially formulated fertilizers of the Fitofert brand, which are adapted to the needs of the given crops.
In the basic fertilizing, a complex fertilizer with an emphasized potassium content and a basic nitrogen content, as well as pelletized manure BioFert green 4:3:3, in the amount of 800-1000 kg/ha, were introduced into the soil.
At the beginning of the growing season, after planting, it is necessary to apply Fitofert Kristal 10:40:10 once in the amount of 2g per plant, with the combination of foliar fertilizer Fitofert Humistart 4:12:5, which has a biostimulating role in the development of the root system.
In the vegetative growth of spring crops, it is recommended to apply Fitofert Kristal Melon 14:7:28+3.5 MgO + ME in the amount of 4g per plant per week (watering), with the combination of Fitofert Bormax 20 in a concentration of 0.3% and Fitofert Bioflex-L in a concentration of 0.4%, which is best applied over the leaves.
Fitofert Kristal Melon 14:7:28 + 3.5 MgO + ME is a formulation specially designed for the needs of heather crops and must be applied until the end of the vegetation period according to the instructions already mentioned. What needs to be changed is the combination with the preparations that we recommend over the leaves, depending on the phenophase and the needs of the plants.
At the beginning of the harvest, it is necessary to add Fitofert Magni-Cal B to the Crystal Melon preparation, which contains the necessary amount of calcium for fruit formation, with an additional boron content that improves the absorption of calcium and its incorporation into cell walls. Calcium gives the fruits the necessary firmness and ensures the quality of the fruits.
