CULTURAL ADVICE ON COTTON WITH ZEOPROFIT HELLAS FERTILIZERS.
Cotton prefers slightly acid to neutral reaction. Although cotton has high K requirements, it often does not require K-lubrication, since the soils on which the cotton is grown are usually rich in K and poor in N. The N-lubrication can range from 0-20 kg / with the amount of production and the nitrogen content of the soil.
The application of N-lubrication by Dose is so necessary, the larger the total amount of N, while where little N is used, then the placement of the fertilizer close to the seed is important.
The lubrication of the cotton can be based on the removal of nutrients from the soil is removed if only output fiber and seeds and having made the correction depending on the soil reserves
Lubrication can also be based on phylogenetics. As critical concentrations are considered to be 0.2% NO3-N (in the stalks) during flowering 0.35% P (in the leaf blade) 2.0% and 0.2% Mg (petioles) in the formation of leaf nuts which just matured.
Cotton has increased demands on boron (B) (50-100gr / ha) and may need lubrication with B on some soils.
On soils with high pH, Zn may be required, while Fe may be missing in irrigated soils by reversing the redox conditions.
