OPTYSIL

DESCRIPTION

Silicon is one of the major component of the Earth’s crust. In soil, the majority of silicon occurs in a form of silica, which is subjected to limited and slow weathering releasing low amounts of monosilicic acid – the only plant available form of silicon. Monosilic acid occurs in soil in low amounts and is very unstable. Plants can uptake it in very limited amount, therefore foliar application of silicon in a proper form is very important.

OPTYSIL® – APPLICATION

OPTYSIL® is recommended for use in the cultivation of all agricultural, fruit and vegetable crops in the form of foliar sprays, fertigation and irrigation
