Nutrient comments:

Nitrogen deficiencies become evident just prior to or during flower and fruit set.

Symptoms include yellow coloured foliage, poor flowering, yield and stunted growth.

Deficiency could be the result of a shortage created during the previous season as citrus store N in the woody parts which can then be utilised in spring.

Excessive amounts of N applied at this time can result in poor fruit quality, particularly affecting fruit colour, delaying maturity, reducing juice content and thickened skins.

Phosphorous deficiency symptoms are usually only evident in poor quality fruit. Excessive rates of phosphorous fertiliser may suppress the uptake of zinc.

Potassium in soil and foliage is often high in orchards (especially if established from old kiwifruit orchards) adjust fertiliser accordingly May induce magnesium deficiency

Magnesium deficiencies may occur during years of heavy crops, may also be induced by high rates of potassium fertiliser on soils with marginal magnesium levels. Symptoms include yellowing of leaves with an inverted v of green tissue at the base of the leaf. Can be corrected using foliar spray.

Manganese and zinc deficiencies often coincide and tend to occur in soils with a high pH, higher than 6.5, particularly for the most common root stock, Poncirus trifoliate.

Can be corrected using foliar sprays.

Lemons have a higher potassium requirement than most other citrus crops.
