Nutritional balance in winter vegetables is key to ensuring profitability and final crop quality. In this context, Nutrol^® 20 is presented as an advanced solution that combines crop nutrition and stimulation.

Nutrol^® 20 is a high-purity animal protein hydrolysate that naturally contains NPK (2-4-6), free amino acids, organic matter, and other essential nutrients. Its formulation provides immediate metabolic energy and improves nutrient uptake efficiency, strengthening the root system, plant structure, and overall productivity. Thanks to its balance between organic and mineral compounds, Nutrol^® 20 optimizes the availability of nutrients in the soil, promoting uniform and sustained growth even under low-temperature or limited physiological activity conditions.

In winter vegetable crops, Nutrol^® 20 acts as a natural stimulant that enhances the plant’s physiological processes, improving its response to thermal, water, or saline stress. Its high-quality organic fraction (rich in short-chain peptides and amino acids) increases cell permeability and promotes greater assimilation of applied mineral nutrients, resulting in stronger tissues and an active root system throughout the growing cycle.

Nutrol^® 20 can be applied through fertigation or foliar spraying, providing a fast and visible response at any stage of vegetative development. It is certified for use in Organic Farming, integrating perfectly into sustainable nutrition programs and efficient management of winter vegetable crops.

The use of Nutrol^® 20 is recommended for all types of crops. As a general guideline, the following applications are advised:

Broccoli:

Nutrol^® 20 acts very effectively in broccoli crops from the early stages of growth, stimulating root development and the formation of a balanced vegetative mass. Its contribution of animal protein and organic phosphorus boosts the plant’s metabolic activity, resulting in more compact, firm, and intensely green heads. It promotes more uniform growth and reduces the incidence of hollow stems or deformities, ensuring homogeneous and high-value production.

It is recommended to carry out 4 to 5 applications via fertigation at a rate of 20 to 40 l/ha every 10 to 15 days, especially during vegetative growth and before curd formation.

These indications are for guidance only and should be adjusted according to professional technical criteria. For optimal management, consult an agronomic advisor or contact our technical department.

Cauliflower:

Nutrol^® 20 ensures vigorous and balanced growth from transplanting, leading to white, compact, and well-shaped heads. Thanks to its protein fraction and slow-release organic phosphorus, it improves nutrient assimilation and energy translocation during critical stages of the cycle.

Apply 4 to 5 times during the crop cycle, by fertigation at 15–30 l/ha every 12 to 15 days, prioritizing active growth and curd formation stages.

These indications are for guidance only and should be adjusted according to professional technical criteria. For optimal management, consult an agronomic advisor or contact our technical department.

Cabbage:

Nutrol^® 20 provides vigor and vegetative balance, promoting proper head formation and preventing cracking or dehydration. Its content of natural amino acids and potassium strengthens tissues and improves final product consistency.

Apply 4 to 5 times throughout the cycle via fertigation at 20–30 l/ha every 12 to 15 days, from the beginning of head formation to the compaction phase.

These indications are for guidance only and should be adjusted according to professional technical criteria. For optimal management, consult an agronomic advisor or contact our technical department.

Lettuce:

Nutrol^® 20 promotes harmonious and sustained growth, encouraging well-closed heads, firm leaves, and a bright green color. Its protein nature enhances nitrogen and phosphorus uptake, providing energy during high-demand periods.

Apply 3 to 4 times during the cycle via fertigation at 15–25 l/ha every 10 to 12 days, especially during active growth and head formation.

These indications are for guidance only and should be adjusted according to professional technical criteria. For optimal management, consult an agronomic advisor or contact our technical department.

Swiss chard:

Nutrol^® 20 stimulates vigorous and continuous leaf development, producing large, fleshy, and intensely green leaves. Its organic matter and highly assimilable proteins improve soil structure and activate beneficial microbiology.

Apply 6 to 8 times per production cycle via fertigation at 20–30 l/ha every 12 to 15 days, especially after harvest cuts, to maintain vigor and regrowth capacity.

These indications are for guidance only and should be adjusted according to professional technical criteria. For optimal management, consult an agronomic advisor or contact our technical department.

Spinach:

Nutrol^® 20 provides a rapid vegetative response, especially in short winter cycles, encouraging larger leaves with optimal color and texture. Its biostimulant action enhances nutrient assimilation and photosynthetic capacity.

Apply 3 to 4 times during the cycle by fertigation at 15–25 l/ha every 8 to 10 days, from early growth to leaf enlargement.

These indications are for guidance only and should be adjusted according to professional technical criteria. For optimal management, consult an agronomic advisor or contact our technical department.

Garlic:

Nutrol^® 20 stimulates root development and the formation of homogeneous, well-sized bulbs. Its protein and mineral components enhance phosphorus and potassium uptake, improving bulb filling and storage life.

Apply 5 to 6 times during the cycle by fertigation at 20–40 l/ha every 12 to 15 days, from vegetative growth to bulb initiation.

These indications are for guidance only and should be adjusted according to professional technical criteria. For optimal management, consult an agronomic advisor or contact our technical department.

Onion:

Nutrol^® 20 promotes a strong root system and balanced plant growth, resulting in uniform, well-calibrated bulbs. The combination of phosphorus, potassium, and organic matter strengthens cell structure and reduces rot incidence.

Apply 5 to 6 times during the cycle by fertigation at 20–40 l/ha every 12 to 15 days, from vegetative development to final bulb enlargement.

These indications are for guidance only and should be adjusted according to professional technical criteria. For optimal management, consult an agronomic advisor or contact our technical department.

Leek:

Nutrol^® 20 promotes balanced vegetative growth and uniform stem elongation, improving resistance to thermal or water stress. Its animal-derived composition enhances soil microbial activity and strengthens tissue structure.

Apply 4 to 5 times via fertigation at 20–30 l/ha every 12 to 15 days, from active growth to the pre-harvest phase.

These indications are for guidance only and should be adjusted according to professional technical criteria. For optimal management, consult an agronomic advisor or contact our technical department.

Optimization of growth and quality in winter vegetables with Nutrol^® 20.

Nutrol^® 20 represents a new generation of organic fertilization adapted to the current demands of horticultural production. Its balance between phosphorus, potassium, and natural proteins makes it an essential ally for achieving vigorous, well-structured, and highly productive plants even under cold or low metabolic activity conditions.

Ultimately, it is a product that combines agronomic efficiency, natural origin, and visible results, positioning itself as an indispensable tool for growers who value quality and sustainability in their production systems.

To maximize fertilization program efficiency, it is essential to perform soil and tissue analyses, adjusting doses according to crop needs. Proper irrigation management ensures optimal nutrient uptake. Foliar applications should be made during the cooler hours of the day to enhance effectiveness and minimize evaporation losses.
