Broccoli fertilization with Rizosol^® Calcio and Protogama^® guarantees a healthy and well-balanced crop from the very beginning, prepared to face the productive and bulking phases with vigor, resulting in compact, firm, and top-quality commercial heads.

Broccoli is a crop with very high nutritional demands that requires precise management to achieve consistent, uniform, and well-colored heads. In this context, our fertilizers Rizosol^® Calcio and Protogama^® represent a highly effective fertilization strategy, acting in a complementary way to enhance both vegetative development and the final quality of the head.

To obtain high-value heads, it is essential to establish an active root system capable of efficiently exploring the soil profile, ensure a constant supply of calcium that strengthens tissue consistency and prevents physiological disorders such as internal necrosis or hollow stems, and provide a balanced nutrition with amino acids and organic matter that promote nutrient uptake, assimilation, and crop tolerance under stress conditions.

Rizosol^® Calcio: A strong root system for a secure production

Rizosol^® Calcio is a root stimulant that also provides highly available calcium. Its application activates plant metabolism, especially in the roots, ensuring excellent crop development.

The use of Rizosol^® Calcio promotes optimal root development, resulting in better crop establishment, increased nutrient uptake, and a stronger response during critical growth stages.

It is recommended to apply Rizosol^® Calcio through fertigation at a rate of 20 l/ha after crop establishment, performing 2 to 3 applications every 10–15 days.

These guidelines are indicative and should be adjusted according to specialized technical criteria. For optimal management, consult an agronomic advisor or contact our technical department.

Protogama^®: Vigorous, balanced, and productive crop

Protogama^® is a powerful protein-based biostimulant of animal origin that naturally contains NPK (4-6-8), amino acids, organic matter, and essential micronutrients.

The application of Protogama^® promotes a vigorous crop start, increases photosynthetic activity, stimulates biomass production, and accelerates plant recovery under stress conditions such as drought, heat stress, or transplanting.

It is recommended to apply 10 to 20 l/ha of Protogama^® through fertigation, from the beginning of the crop until the start of the bulking phase. In combination with Rizosol^® Calcio it enhances nutrient uptake and maximizes productive performance.

These guidelines are indicative and should be adjusted according to specialized technical criteria. For optimal management, consult an agronomic advisor or contact our technical department.

Rizosol^® Calcio + Protogama^®: Strong broccoli from the start, quality through to harvest.

The combined use of Rizosol^® Calcio and Protogama^® in broccoli fertilization allows precise response to the crop’s nutritional needs, ensuring not only the visual and structural quality of the head, but also its resistance during post-harvest handling and storage. The result is healthier, firmer, more uniform, and more profitable broccoli.

To maximize the efficiency of the fertilization program, it is essential to perform soil and tissue analysis, adjusting doses according to crop requirements. Proper irrigation management ensures optimal nutrient uptake. Foliar applications are recommended during the cooler hours of the day to increase efficiency and reduce evaporation losses.
