Due to its high yield and thus increased biomass production, maize needs a sufficient supply of nutrients in a well balanced ratio. It has a deep root system, which allows it to utilize the nutrients found in the lower layers. Its cultivation is most efficient in deep soils of medium composition, well drained, with a high organic matter content, high water content and a pH of 5.5 to 7.5.

Nitrogen (N) is the most important nutrient and plays a key role in crop growth and yield. Very large quantities of nitrogen are required, as yields averaging more than or equal to 1,000 kg per stremma require 20-30 kg of nitrogen per stremma , while always taking into account the leaching factor. At the stage of ripening, the seed contains more than 70% of the plant’s total nitrogen. Its application should be done in 2 doses, basal and surface.

Phosphorus (P) is applied in the basal fertilization at a rate of 6 kg per stremma depending on the soil phosphorus reserves and the intensity of previous phosphorus fertilizations. Potassium (K) is applied in the basal fertilization at a rate of 20 kg per stremma.

Regarding trace elements, maize does not usually suffer from nutrient deficiencies, except for that of zinc, which occurs during the vegetative stage of plant growth, causing chlorosis of the middle leaves and delayed growth. As a preventive measure, zinc is applied during the basal fertilization of the crop and, if necessary, after the occurrence of nutrient deficiencies, by means of foliar sprays during the full development of the crop. For the treatment of boron deficiency in maize cultivation it is recommended to use BoroAgro, by means of foliar application or with drip irrigation.
