UREA PHOSPHATE
STRAIGHT FERTILIZER CONTAIN ESSENTIAL TOW MACRO NUTRIENTS
NITROGEN & PHOSPHOROUS
GENERAL INFORMATION
QUALI MAX® UP is totally water soluble straight fertilizer consist of 18% NITROGEN and 44% PHOSPHOROUS (38% UREA and 62% PHOSPHORIC ACID) with highest efficacy for nutrient uptake by roots especially in alkaline and saline soils. Totally water soluble and rapidly dissolves in water without any clogging of drip outlets. It has an ACID pH to prevent scale formation in irrigation systems when employ in hard water.
Nitrogen as urea form causes better absorbance of other nutrients when applied in soil or by foliar. Due to pH reduction of the spray tank solution it will improve the stability and efficacy of pesticides when use together. For prevent of scorching in foliar application it’s recommended to avoid the pH lower than 4.5 in solution tank. High levels of phosphorus with nitrogen are more used for root development at an early stage in the growing season.
Bellow table shows how much of the product need to neutralize bicarbonate content in hard water.

QUALI MAX® UP can be used in all methods of fertigation and also by foliage application at the rate of following.
SOIL & FERTIGATION: 30-50 Kg/Ha for field crop and greenhouse according to soil analysis and deficiency symptoms. First use after planting and repeat until flowering. Fruit tree 50-100 g/Tree in early spring, after flowering and with observe deficiency symptoms.
FOLIAR: ready 0.5-1 % solution as the product and use in afternoon except flowering and fruit maturity.

QUALI MAX® UP has higher solubility than other source of P like DAP, MAP, and MKP in pure water at 20°C is 960 g/l, meanwhile it is 690 g/l for DAP, 380 g/l MAP and 230 g/l for MKP.
QUALI MAX® UP is also compatible with most pesticides and fungicide for foliar applications except those containing Calcium which causes precipitation of Gypsum (CaSO4).
It cannot apply with strong alkaline products. It is highly recommended to conduct a small scale trial to check the compatibility of the mixture before large scale operation and injection into the irrigation system as fertigation.
QUALI MAX® UP can be stored in unopened original containers for several years. Opened containers should be used up or be resealed immediately. Any hardening of the product that may occur during prolonged storage does not influence the chemical quality and solubility of the product and it can be used effectively on crops in the recommended dosage. It is recommended to store the product in a cool and ventilated place, keep away from foodstuffs, children and animals feeds.
