Presented at the 3rd e-Conference on Agricultural BioSciences
(IeCAB 2010), held online from1st -15th June 2010 at

The BBCH- File and its use
•
•
The BBCH- recommendations for Lithovit application on
different crops is written by a number of distinguished Agro
Scientists and Biologists after long periods of trials.
The file provides information in the form of a table with
plant name, number of applications, amount of lithovit per
application (kg/hectare), total amount per growth period
(kg/hectare); codes referring to text and pictures at the
BBCH growth stage of the plant at each application.

Preparation of the suspension and
dosage
•
•
•
•
Lithovit is natural limestone which is almost insoluble in water.
In order to use it as foliar fertilizer, it must be suspended as
0.5% aqueous suspension (500 grams in 100 liters water) and
sprayed normally.
The suspension must be stirred to keep it stable. Sprayer
carried on the back should be shaken from time to time.
Dosage: 1.5 kg (300 liters of suspension) / application and
hectare
