CHARACTERISTICS FERTILIZERS FOR PISTACHIO

ROOT

It has a taproot, but in most commercial orchards, the root system tends to be fibrous.

STEM

In commercial plantations, trees are trained to grow with a single trunk. When grown naturally, it may develop multiple trunks.

LEAVES

Leaves are deciduous, alternate, compound, odd-pinnate, with 3 to 5 oval-shaped leaflets rounded at the tip.

FLOWERS

Flowers emerge on one-year-old lateral branches, before leaf budding. Male and female flowers are found on different cultivars. In general, they are small, petal-less, grouped in axillary inflorescences in the form of clusters, which bloom gradually. Their duration depends on the cultivar.

NUTRITIONAL NEEDS

Pistachio is a very hardy crop, but it responds well to the application of fertilizers, which must be adjusted according to factors such as: soil depth, texture, planting density, management system (dryland or irrigated), rootstock, care (pruning), pH, and nutrient reserves and availability in the soil.

*(Year of loading ON or unloading OFF)

There are also other essential elements like Ca, Mg, Fe, Mn, B, Cu, Zn, and Mo, with special emphasis on boron requirements, as this micronutrient plays key roles, such as increasing fruit set, improving the percentage of split nuts, and reducing the number of empty fruits.
