GRASSKEL 50
GRASSKEL 50 is a high-graduation liquid potassium fertiliser formulated with EDTA which facilitates optimal uptake of potassium either by root or leaf application. It increases the precocity, quality and sugar content of fruits. It also enhances the fatty yield of fruits and seeds.
It is recommended that the treatments should be applied from the end of fattening or start of maturation, monitoring the pH of the solution.
Family: Specialities
Application and dose
LEAF APPLICATION
Maximum general dose: 100-150 cc/l
Olives: applying the product neat, and monitoring the pH of the mix properly, the dose can be raised up to 300-500 cc/hl.
ROOT APPLICATION
Approximate total use: 40-60 l/ha to be distributed over the cycle.
Horticulturals: 7-15 l/ha and application.
Strawberry: 10 l/ha and application.
Stone fruits: before sprouting and up to setting, 15-20 l/ha in 2 applications. From setting up to the change in colour, 30-40 l/ha in 3 applications.
Pome fruits: before sprouting and up to setting, 20 l/ha in 2 applications. From setting up to the change in colour, 20-30 l/ha in 3 applications.
Citruses: 40-60 l/ha distributed over 4-6 applications, during the crop cycle starting with the setting phase.
Olives: 40 l/ha distributed over 3 applications, from pre-flowering from the formation of the olive stone (around the first half of July), up to the moment of change of colour.
