Orange tree fertilization in spring is decisive for the proper start of the productive cycle, as this period brings together sprouting, flowering and the beginning of fruit development, stages that involve high nutritional demand and require a fertilization strategy capable of adapting to the actual pace of both the crop and the soil.

A well-planned basal fertilization at this stage helps prevent vegetative imbalances, improve nutrient efficiency and lay the foundations for stable and profitable production. During spring, one of the main challenges for orange trees is meeting the progressive increase in nitrogen requirements while the root system and soil biological activity become active after winter. Rapid-release mineral nitrogen applications may cause excessive vegetative growth, irregular flowering and poorer fruit set, as well as increasing the risk of nutrient losses through leaching, especially in soils with low organic matter content.

In this context, organic nitrogen becomes a key tool in orange tree fertilization in spring. Its gradual release, linked to soil microbial activity, ensures a constant nitrogen availability during sprouting and flowering, adjusting to the crop’s real absorption capacity and promoting balanced vegetative development. At the same time, the associated organic matter improves soil structure, increases water and nutrient retention and stimulates microbiological activity, which are essential factors for efficient nutrition from the beginning of the cycle.

Fertilone^® 10.5.5 is an organic-mineral NPK 10-5-5 fertilizer especially suitable as a spring basal fertilizer for orange trees. It is characterized by its high content of high-quality organic matter, obtained through an exclusive and completely natural composting process.

Fertilone^® 10.5.5 features a high organic nitrogen content that allows for progressive and sustained release, adapting to the crop’s absorption rate, improving soil fertility and stimulating microbial activity, resulting in more efficient utilization of the phosphorus and potassium present in the formulation.

As a spring basal fertilizer in productive orange orchards with average yields ranging from 30 to 50 tonnes per hectare, Fertilone^® 10.5.5 is recommended at indicative rates of 800 to 1,200 kg per hectare applied before the main sprouting. In plots with high productive potential or soils with low organic matter content, the rate may be adjusted up to 1,300 or 1,500 kg per hectare. Expressed per tree and considering typical planting densities of 400 to 500 trees per hectare, the recommended rate is around 2 to 3 kg per tree, reaching 3 to 4 kg per tree in higher-yielding orchards. The fertilizer should be evenly distributed over the canopy projection area and lightly incorporated into the soil.

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