Establishing an alfalfa stand requires a basal fertilization strategy consistent with the physiology of the crop and aimed at promoting both its establishment and long-term persistence. Fertilone^® 4.8.14 provides an organo-mineral balance designed to support early development without interfering with biological nitrogen fixation, offering the soil and the plant a stable foundation for a productive multi-year cycle.

Alfalfa obtains most of its nitrogen through symbiosis with nodulating bacteria, meaning that an excess of mineral nitrogen can reduce nodulation and delay the onset of biological fixation.

For this symbiosis to function efficiently, the crop requires well-aerated soils with good cation exchange capacity and active microbial populations. Phosphorus availability during establishment and adequate potassium levels throughout the cycle largely determine the crop’s ability to explore the soil, fix nitrogen and maintain stable vegetative vigor.

The crop also has a high potassium demand, essential for sustaining regrowth after each cut and for maintaining a balanced metabolism under water-stress conditions.

Phosphorus plays a decisive role in the formation of active nodules and in root architecture, while elements such as calcium, magnesium and sulfur enhance the crop’s physiological balance and structural stability. Overall, alfalfa requires a basal fertilization plan that prioritizes these nutrients and contributes to improving the physical and biological properties of the soil.

Fertilone^® 4.8.14

Fertilone^® 4.8.14 is a 4-8-14 NPK organo-mineral fertilizer precisely aligned with the nutritional requirements of alfalfa. Its moderate nitrogen content supports early development without interfering with biological fixation, while its phosphorus and potassium levels promote a deep and active root system, reinforcing vegetative recovery and metabolic stability throughout the crop cycle.

The organic fraction, obtained through an exclusive natural composting process, is one of the product’s key strengths. Fertilone^® 4.8.14 improves soil structure, increases moisture retention and enhances microbial activity. These conditions create an optimal edaphic environment for nodule formation and function, contributing to more efficient and stable biological nitrogen fixation.

The recommended application rate for alfalfa ranges between 400 and 600 kg/ha of Fertilone^® 4.8.14 as basal fertilization before sowing, adjusting toward the upper range in soils with low phosphorus or potassium availability. Light incorporation into the surface layer favors the gradual release of nutrients and ensures that the crop has access to a balanced nutritional base from the outset.

These recommendations are indicative and should be adjusted according to specialized technical criteria. For personalized guidance, consult an agronomic advisor or contact our technical department.
