DROPFERTTM 18/18/18
Product Description
DROPFERT™ 18/18/18 + micro is a crystalline, fully water-soluble NPK fertilizer (18/18/18) with magnesium, sulphur and microelements for fertigation of crops in inert organic substrates and in the soil. It can be used to prepare concentrated solutions used with proportional dispensers or diluted ready for use nutrient solution.The high quality of the components used in the production of the fertiliser and the appropriate form of the nutrients in the fertiliser ensure their high availability to plants. Fully chelated micronutrients ensure stability in concentrated and ready-to-use media and allow mixing with other agrochemicals.
DROPFERT™ 18/18/18 + micro is recommended for in all stages of plant development, throughout the growing season, particularly for plants in poor condition.

Directions for Use
Preparing ready for use nutrient solutions:
Use DROPFERT™ 18/18/18 as water solution with the concentration 0.03–0.2%. The required concentration of fertilizer is obtained by dissolving 0.3 to 2 kg of fertilizer in 1,000l of water, respectively. Using DROPFERT™ 18/18/18 in nutrient solution along with other fertilizer, do not exceed a total concentration of 0.2% of all ingredients in the solution.
Preparing concentrated solutions:
To prepare 100 times concentrated solution add 750L of water into the spray container, then – while the agitator is turned on add gradually from 30 to 100 kg of DROPFERT™ 18/18/18 (according to the required content of nutrients in the nutrient solution). After complete dissolution of fertilizer, fill the container with water to a volume of 1000 l. Diluting a solution prepared in this way in a proportion 1:100 allows to obtain a ready to use solution with a concentration of 0.03-0.1%.
These recommendations are of general nature. The nutrient content must always be adapted to the individual needs plants and growing conditions. Calculations should take into account the nutrient content of the water used to prepare the nutrient solution.
Concentrated DROPFERT™ 18/18/18 solutions should be prepared in a separate container than a concentrated solution of calcium nitrate.
