What does it do?
This calculator provides a person buying agricultural land for production, with a guide to how much should be paid for the land in question.
Land has a value as a store of value (long term investment) as well as a production resource generating income each year. In terms of production, the value of land to the producer will depend upon the level of technology applied and the skills of the farmer. Therefore nominal prices for land, such as the Gold Crown, need to be adjusted in each individual case to determine the real value (the price worth paying) for the land concerned. This calculation produces the 'Investment Value of Land' which is equivalent to a price.

Information used
In order to calculate the investment value of land the calculator needs the expected return on investment (eri), expressed as a percentage and the net annual absolute return on a hectare of land (arh). Use can be made of the average aggregate gross margins per hectare. The annual average variable costs of production are also required (avc).

Forumla
Investment Value of Land (Investment price) = ((arh x 100)/(eri)) - avc
where:
arh = annual return/ha.
eri = expected annual return (expressed as a percentage)
avc = average annual variable costs/ha.

Scripts & code details
This is a simple system consisting of three nodes. Thus in DScript:
Root:=(Perf,Calc,Present)
Node:Perf requests data input;
Node:Calc calculates the result as per the above formula;
Node:Present presents the result in short report text format.
The request for data makes use of the DScript primitive dialog() which has the following arguments:
dialog( template, buttons, values, title, fill, envelope)

Design: By Navatec.com for the Hungarian Agricultural Foundation online agricultural extension system, AFA-Agronet. The system has 120 online calculators and optimization systems and was the largest online system build in server side DScript and ECMAScript in Central Europe. This bi-lingual system (Hungarian & English) ran from 2000 to 2010. A performance review completed in 2009 recommended further investment to upgrade & extend this system. This work is being undertaken by VisualModel.com.
