Citrus fruits

Citrus fruits include clementines, oranges, lemons, etc. 

These crops, like all other perennial crops, require a global approach to fertilization.

The factors of productivity and quality are assessed not only on an annual basis for the growth cycle, but also over the life of the orchard to ensure its sustainability.

To meet these short, medium and long term challenges, Angibaud designs and develops end-to-end nutrition programs to ensure efficient and sustainable production, including organic amendment and fertilizers, leaf and soluble nutritional supplements, and biostimulants.

Key fertilization aspects

Citrus fertilization must take into account a set of cultivation and environmental parameters to ensure efficient nutrition of the orchard throughout its growth cycle: 

1. The pedo-climatic context (soil type, temperature, precipitation)

2. The species and the production system (vitality, nutritional sensitivity, planting density, cultivation practices)

3. Variety and production targets (quantitative and/or qualitative criteria)

Strategic areas of fertilization

In order to meet the annual nutrient requirements and to ensure the sustainability of the orchard, it is necessary to pay attention to the following factors: 

Orchard sustainability: 

  • Increase organic matter and biological fertility of the soil
  • Ensure the establishment and recovery of young plants
  • Promote flower initiation and carbohydrate storage

Productivity and quality of yields: 

  • Enrich root and vegetative growth
  • Prevent and correct nutritional deficiencies
  • Create the best possible flowering
  • Strengthen cell multiplication
  • Promote fruit filling and growth
  • Optimise the quality of the harvest

Solutions and a program adapted to each situation encountered

Bior®

Organic amendment based on plant and fish guano.

Bior is an organic amendment based on plant matter and fish guano, with a high humic potential. Bior is a precursor of humus and biological activity in soils. It also promotes the exchange of nutrients between the soil, fertilizers and plants.

NPK composition (%) 2-0.8-1.7 – Organic matter on gross 70% – C/N ratio 17.5
Can be used in organic farming

Guanumus® Evolution

Organic fertilizer made from plants and fish guano.

Guanumus Evolution is an organic fertilizer developed on the basis of plant and fish guano with high humic potential. Guanumus Evolution acts in particular on the biological fertility of soils thanks to the action of fish guano on the microbial activity and population. Guanumus Evolution promotes mineralisation and nutrient release. Guanumus Evolution provides complete and balanced organic nutrition for the crop.

NPK composition (%)
3-2.5-3+3 MgO
Organic matter on gross 50
C/N ratio 8.3
Can be used in organic farming
Fertilizer NFU 42-001

Ferveg®

Complete range of iron chelates to prevent and correct iron chlorosis.

Ferveg is a complete range of iron chelates (HBED, EDDHA, DTPA, EDTA…) that can be used in the soil, in fertirrigation or in leaf app to prevent and correct iron chlorosis.

Stimurel®

Complex of biostimulant and leaf nutrients 100% organic to support the growth and quality of crops.

Stimurel is an organic liquid biostimulant, based on fish proteins obtained by enzymatic hydrolysis, which can be used in organic farming. Applied at flowering, Stimurel stimulates the growth of the plants and promotes the precocity and the quality of the fruits (size, colour, conservation).

Composition (% W/V)
50 g/l N + 70 g/l K2O

Prevent and correct iron chlorosis

Despite generally sufficient stocks in the soil, the availability and assimilation of iron by the roots remains complex. Specific pedo-climatic conditions such as calcareous or alkaline soils or prolonged drought hinder the absorption of iron and can cause numerous physiological disorders (reduced chlorophyll synthesis, shortening of the growth cycle, loss of quality, etc.).

To combat this nutrient deficiency, which can be recognised by the yellowing and drying of the leaves, Angibaud recommends the preventive and/or remedial application of iron chelates to the soil or as a leaf spray. The Ferveg Ⓡ range offers a complete range of iron chelates (HBED, EDDHA, EDTA…), suitable for use in organic farming, adapted to all farming situations in order to guarantee optimal productivity and production quality.
