Trials have shown that balanced nutrition with N, P, K, and the micronutrients, boron, iron, manganese and zinc, will help to improve citrus yield through increasing fruit weight.

Peel splitting is often caused by extreme fluctuations in soil moisture as well as temperature and humidity.

During the ripening process fruit acids are degraded, the sugar content increases and the sugar/acid ratio reaches a higher value.

Root rot, due to Phytophthora spp., can be controlled by systemic fungicide use.

HLB, also known as citrus greening disease, is fatal for citrus trees.

Any unnatural coloration of citrus leaves needs to be investigated. A darker greening, while uncommon, could be a result of a nutrient deficiency.

As with leaf yellowing, any blotching or other irregularity in citrus leaf color needs to be checked.

Balanced crop nutrition of all major and micro nutrients is essential to help build a tree structure that can support this fruit load and ensure that the fruit fills to potential as well as meet the market requirements.

There is a number variables that define citrus quality requirements. Quality standards differ depending on the citrus type, growth region and the market.

A healthy grove is the key to consistent, high yields of quality fruit.

It is essential to implement a balanced nutrition including macronutients and micronutrients in order to achieve the best results possible for your crop.

Find out which nutrients are most important at different growth stages.

Fresh and processed fruit.

The aim of any grower is a high yielding, quality crop that meets the needs of the end user.

Oranges, mandarins, grapefruits, pomelos, lemons, limes, kumquat and limquat.

Nitrogen is a key component of enzymes, vitamins, chlorophyll and other cell constituents, which are essential for crop growth and development.

Phosphorus is a component of nucleic acids and lipids and is important in metabolism, energy transfer, and photosynthate transport during citrus production.

Alongside nitrogen, potassium is one of the most important nutrients for citrus production.

Calcium is a key component of cell walls and also has a direct influence on the regulation of enzyme systems, phytohormone activities and nutrient uptake.

Magnesium is needed for many processes in the citrus tree, particularly chlorophyll production.

Sulfur is an important component of enzymes and other proteins, and is required for chlorophyll formation in citrus production.

Boron is involved in various enzyme systems and in carbohydrate metabolism and translocation.

Copper in citrus affects photosynthesis, plant protein production, pollen viability and therefore fruit set, respiration and water use efficiency.

In citrus production, iron acts as a catalyst in oxidation/reduction reactions; is involved in respiration; photosynthesis; and the reduction of nitrate and sulfate.

In citrus production, manganese is involved with photosynthesis, efficient use of N, protein metabolism and enzyme activation.

Citrus utilizes nitrogen mostly in the nitrate form and maximum uptake occurs from N applications made during the periods of active growth.

Molybdenum is essential for nitrogen metabolism in citrus production.

Deficiency of zinc significantly reduces citrus growth and yield potential.
