# APTM: A Model for Pervasive Traceability of Agrochemicals
## 5 Implementation and Evaluation
### Evaluation Aspects
The interview was carried out on a farmer with extensive and recognized experience in agricultural monoculture of soybeans and corn, aiming to carry out a proof of concept of the model. The commented questions and answers are listed in Table 5. The questions briefly present: The farmer recognizes that a special place for storing agrochemical products is needed. Empty agrochemical containers are also stored on the farm until they are taken to the disposal center, and they also need exceptional control. He recognizes that a special guardroom is needed. The need for control over the amount (in milliliters, liters, or gallons) in use is recognized. The farmer indicates interest in knowing the agrochemicals' traffic on the farm. The opening of storage environments should issue alerts to the farmer. The farmer also shows an interest in a system for predicting and warning of future events. The farmer confirms that the farm is part of a supply chain. The farm is interested in using system data with control and inspection entities. The farmer shows interest in testing new technologies. The farmer recognizes the possibility of using the records of transactions in future operations, such as exchanges for carbon credits, tax credits, or discounts with the supplier. \begin{table}
