DESC:TITLE OF THE INVENTION: A DEVICE FOR REAL-TIME SOIL ANALYSIS
FIELD OF THE INVENTION

BACKGROUND OF THE INVENTION
Generally soil testing is done in laboratories, by sending the required soil samples to the labs, which is time consuming and requires big infrastructure with trained professionals.
Though soil testing may be carried out for a variety of reasons, one of the major reasons is to determine the available concentrations of plant nutrients. Based on the determined concentrations, appropriate recommendations may be made for the use of fertilizers and other growth stimulating agents.
Since soil testing in laboratories is time consuming, it may not be possible to conduct soil tests on a frequent basis. However, the nature of a particular soil is dynamic and is influenced by a variety of environmental and ecological factors.
Thus, it may be advisable to test soil samples on a periodic basis. This may help in early determination of soil fertility degradation, which, in turn, may help in early implementation of corrective action.
There is, therefore, a need in the art for a reliable device which can analyse soil samples in real-time with minimum effort, in less time, and less cost, and requires minimal human intervention.

The soil sample solution is made by taking 10 ml dry soil in a beaker. 50 ml of extraction solution is collected in the beaker through a chemical dispenser. The solution is shaken thoroughly and allowed to sit for about 10 minutes until all the soil settles at the bottom.
An inverted cone is formed with a filter paper of about 25 microns. The soil sample solution is filtered through the inverted cone to obtain a particle-free sample solution.
For the testing of Electrical Conductivity, about 20 grams of dry soil is taken in a beaker. 40 ml of distilled water is collected in the beaker through a chemical dispenser. The dispensing of the distilled water occurs automatically by selecting the respective test through the interface (101) by the at least one user or operator. The solution is shaken well for about thirty minutes.
