Fertilizing in Culture - AGRUMS
Agrums
Productive crop with the least cost

The main types of citrus fruit with economic importance for our country are Orange, lemon and grapefruit. The fertilization of citrus fruit substantially affect production , but the qualitative features . The quantities of fertilizers are different for each tree and also vary from region to region . Thus, before fertilizing would be good to analyze soil and the leaves. The general rule in the fertilization of citrus fruit is the relative dosage of nitrogen in small quantities in combination with potassium in large quantities, which give better quality features . Especially importantance for nutrition of citrus fruit have magnesium and micronutrients, zinc , iron and maganium that impact on the production , as the quality of the fruits . Required micronutrient elements should be added along with basic fertilization .


Needs for nutritional elements for the Orange (grams per tree)
NITROGEN (Ν)PHOSPHORUS (Ρ2Ο5)CALIUM(Κ2Ο)MAGNESIUM(MgO)
300-700 250-300 300-500 50-70


Suggestions for fertilization

Phosphorus, potassium , magnesium , nutrients and of nitrogen (about ½) are provided with basic winter fertilization . Additional fertilization with nitrogen is given at the beginning of summer , and the amount depends on the nutritional status of the tree , the expected production , climate and soil conditions .

We suggest that greater amounts of fertilizer production that suits watching financially.
