Potassium Silicate in Organic Farming

Introduction

The potassium silicate in the aqueous formulation, after spraying on the vegetation, drying, forms a hard inorganic film capable of hindering the activity of parasites with sucking mouthparts such as aphids, mites and diptera.

Due to the high content of potassium and silicon that can be absorbed by vegetation, it contributes to nutrition and increases the consistency of the cell membrane, improving the physiological state and resistance to abiotic stress of plants.

The alkaline pH also creates a hostile environment, hindering its life, to bacteria that prefer an acidic environment.
It can be mixed with Soft Potassium Soap, enhancing its action in vegetation treatments.

Potassium silicate is allowed in Organic Agriculture

It is commonly used in Log Pulp in both conventional and Biodynamic Agriculture.

What is Log Pulp?

It is the evolution of a practice in use in past centuries in the agricultural world when the trunks were "stuffed" with what was available and available in those periods: cattle dung, lime, copper sulphate.

Individually or mixed together. The operation was generally practiced at the beginning of winter, or at the end of winter, and was used to combat fungi, bacteria and even insects that overwinter on the trunks in the folds of the bark or to limit their ascent from the ground along the trunks.

The alkaline action of lime, or the acid action of cow dung, was exploited.

Examples of log pulp

Bentotamnium 3 kg
Hydrated Lime 3 kg
Potassium silicate 500 cc
Propolis 500 cc

Zeolite 1 kg
Hydrated Lime 3 kg
Potassium silicate 500 cc
Propolis 500 cc

All with the addition of water until you get a spreadable or brushable paste. I believe that the effectiveness is due to the alkaline pH of the medium, as well as to the asphyxiating action.
