The cultivation of orange trees requires balanced nutritional management to ensure abundant yields, fruits of good size, excellent flavor, and a resistant skin that can withstand handling and transport. Fertilone^® 8.8.14 and Bitalkali^® are two excellent organo-mineral alternatives for citrus fertilization during the fruit fattening stage.

During the fruit set and fattening phases, potassium becomes a key nutrient, as it improves fruit filling, sugar accumulation, skin coloration, and pulp firmness. Organo-mineral fertilizers rich in potassium are a strategic tool in this context.

In this sense, Fertilone^® 8.8.14 and Bitalkali^® are two highly effective technical solutions. By combining the gradual release of nutrients with an organic fraction that stimulates soil biological activity, they achieve more efficient and sustainable nutrition aligned with the crop’s requirements. 

Fertilone^® 8.8.14

Fertilone^® 8.8.14 is an organo-mineral NPK pellet fertilizer that combines a high potassium content with nitrogen and phosphorus in balanced proportions. It is designed for use in conventional agriculture and provides a quick crop response thanks to its mineral fraction, while the accompanying organic matter favors long-lasting soil fertility.

In citrus crops such as oranges, Fertilone^® 8.8.14 boosts fruit development during key stages, improves size, coloration, and post-harvest shelf life, and helps maintain balanced trees with good productive load season after season.

Bitalkali^®

Bitalkali^® is an organo-mineral pellet fertilizer certified for use in organic farming. Its formulation is specially designed for crops that require high potassium levels, such as orange trees, also supplying slow-release nitrogen and phosphorus along with high-quality organic matter.

Thanks to its balance and high content of naturally sourced potassium, Bitalkali^® promotes better ripening, higher sugar concentration, and greater resistance to physiological disorders such as fruit cracking or premature drop. In addition, its organic fraction improves soil structure and supports beneficial microbiota.

Both Fertilone^® 8.8.14 and Bitalkali^® are suitable for localized application at the base of the tree or for surface incorporation after light tillage.

Depending on soil condition and expected yield, it is recommended to apply between 800 and 1,500 kg/ha of Fertilone^® 8.8.14 or Bitalkali^® at the end of summer, incorporating into the soil with light tillage.

These indications are for guidance only and should be adjusted according to specialized technical criteria. For optimal management, consulting an agronomic advisor or contacting our technical department is recommended.

Fertilone^® 8.8.14 and Bitalkali^®: Eco and conventional fattening, always organo-mineral.

Both organo-mineral fertilizers are designed for citrus growers seeking high profitability and quality. While Bitalkali^® is recommended for organic citrus production, Fertilone^® 8.8.14 is the perfect option for conventional operations.

To maximize the efficiency of the fertilization program, it is essential to carry out soil and leaf tissue analysis, adjusting doses according to crop needs. Proper irrigation management will ensure optimal nutrient uptake. In addition, foliar applications should be carried out during the cooler hours of the day to maximize effectiveness and minimize evaporation losses.
