Innovation in agriculture


Liquid fertilizers based on nitrogen, phosphorus, potassium and meso elements. The Leaf line presents various formulations able to satisfy the nutritional needs of crops in different phenological stages.


Innovation in agriculture

Each Leaf product contains high-quality materials and it is formulated with agents that improve absorption, eliminating the risk of plant phytotoxicity.

Moreover, they offer high practicality of use in the field.

The liquid formulation makes them suitable for both foliar and fertigation applications.

Leaf family fertilizers are available in 5, 20 and 1.000 L tanks.

Leaf S-Quality

Promotes quality and protein content

LEAF S-QUALITYcontains nitrogen and sulfur totally available for the plant making it effective even at low dosages. LEAF S-QUALITY contains nitrogen in the urea form, faster, and ammonia, more durable over time, which guarantee a balanced development of the crop. LEAF S-QUALITY also provides sulfur which when applied by foliar favors the accumulation of proteins, oil yield, the aroma of wine, if applied to the soil acidifies the rhizosphere and promotes the absorption of nutrients.


  • It promotes quality by promoting the accumulation of proteins, the yield in oil, the aroma of wine thanks to the balanced content of nitrogen and sulfur;
  • It increases productivity by stimulating the plant to absorb the nutrients present in the soil;
  • High efficiency at low doses, nitrogen and sulfur totally available for the plant;

Leaf N-Fast

Efficiency in nitrogen nutrition

LEAF N-FAST is a highly efficient liquid nitrogen fertilizer. Nitrogen in the urea form complexed with lignosulfonates is rapidly absorbed and is 4 times more effective. LEAF N-FAST increases productivity and quality, stimulates photosynthetic activity, vegetative development and the rapid transformation of nitrogen into enzymes and proteins.


  • Increase in productivity and quality, increase in photosynthetic activity, vegetative development and rapid transformation of nitrogen into proteins;
    High efficiency nitrogen fertilizer units are 4 times more effective than granular nitrogen;
    No risk of phytotoxicity even at high dosages;
    It improves the effectiveness of the combined products (whether they are fertilizers and / or pesticides), wetting, tackifying and conveying effect of ligninsulfonates.

Leaf P

PK liquid fertilizer

Leaf P is a liquid fertilizer containing potassium and magnesium phosphites. Leaf P activates plant’s defences, increases photosynthesis and blossoming, stimulates bud formation and improves root development. Ideal for extensive crops, fruit trees and horticultural crops.



  • Favours the development of crops since the earliest stages thanks to magnesium which increases photosynthesis and sugar transport, and to phosphorus which allows a better root development
  • Helps to limit production losses due to biotic and abiotic stress as a result of the presence of phosphites activating plants’ defences
  • Improves the quality of fruits by increasing sugar content and colour
  • Easy to use in foliar application and fertigation, and miscible with the most common products generally used in both treatments

Leaf K

NK liquid fertilizer with low chlorine content

Leaf K is an NK liquid fertilizer completely soluble in water and containing potassium, a fundamental macroelement for sugar and starch accumulation. It is recommended for extensive crops, horticultural crops and fruit trees.



  • Activates processes of ripening anticipating and synchronizing it
  • Improves the quality of fruits increasing sugar content and colour
  • Easy to use both in foliar application and fertigation

Leaf NP

NP liquid fertilizer with Manganese (Mn), and Zinc (Zn)

Leaf NP is an NP liquid fertilizer containing nitrogen, phosphorus, manganese and zinc. The presence of microelements supports photosynthesis and metabolism, and improves fruit colour. Ideal for fruit trees, horticultural and extensive crops.



  • Favours vegetative and root development by rapidly providing phosphorus, manganese and zinc to the plant
  • Allows to increase production since it leads to a major blossoming and fruit set, it synchronises fruit development and ripening
  • Easy to use both in foliar application and fertigation

Leaf NPK

NPK liquid fertilizer with Boron (B), Iron (Fe), and Molybdenum (Mo)

Leaf NPK is a liquid fertilizer containing nitrogen, phosphorus, potassium, boron, iron and molybdenum with completely soluble raw materials and quickly absorbed by plants.



  • Increases the productivity of crops by improving fruit set and providing all the elements useful in the early development stages of fruits
  • Improves the quality of fruits, cereals and protein crops since it favours sugar and protein accumulation
  • Makes the absorption of products associated with it effective thanks to the subacidic pH
  • Easy to use both in foliar application and fertigation

Leaf N

Gradual nitrogen nutrition

LEAF N contains gradual release nitrogen which guarantees constant and prolonged nutrition over time, avoiding vegetative excesses. LEAF N also provides sulfur and boron which increase the protein content, the oil yield and the aromatic profile of the grapes.


  • Stimulates growth gradually, thanks to the slow release nitrogen from dimethylurea;
  • Reduces the risks of vegetative excesses that make the plant more susceptible to biotic and abiotic stress;
  • Increases fruit productivity and quality combined action of nitrogen, sulfur and boron;
  • Compatible with all main products for foliar application (fertilizers and pesticides).
