Availability of materials and data
An inherent principle of publication is that others should be able to replicate and build upon the authors' published claims. Therefore, a condition of publication in AJESMS is that authors are required to make materials, data and associated protocols promptly available to readers without undue qualifications in material transfer agreements. Any restrictions on the availability of materials or information must be disclosed to the publishing team at the time of submission. Supporting data must be made available to Editorial Board Members and reviewers at the time of submission for the purposes of evaluating the manuscript. Reviewers may be asked to comment on the terms of access to materials, methods and/or data sets; AJESMS reserves the right to refuse publication in cases where authors do not provide adequate assurances that they can comply with the publication's requirements for sharing materials.
After publication, readers who encounter refusal by the authors to comply with these policies should contact the AJESMS publishing team. In cases where we are unable to resolve a complaint, the matter may be referred to the authors' funding institution and/or a formal statement of correction may be published, attached online to the publication, stating that readers have been unable to obtain necessary materials to replicate the findings.

Developing a Geographic Information System (GIS) application for soils and crop suitability studies in Atwima District of Ghana
Abstract
This paper reports a study that sought to develop a Geographic Information System (GIS) application for soils and their crops suitability in the Atwima District. The purpose of the study was to digitally capture, store, and analyze the soil map and crops suitability data of the district. GIS is a computer-based system for gathering, storing, manipulating and analyzing spatial data to support decision making. In this study, the soil map of the Atwima district was digitized and analyzed with GIS software called ArcView. The soil characteristics and crops suitability data were also added in tabular form to the database. A thematic map showing soil associations and their crop suitability was then generated from the database and displayed concurrently with the tabular data. Analysis of the map and table proved that it is easier to study soils and their suitable crops from their data displayed concurrently on the desktop. It was therefore concluded that developing GIS application for the study of soils and crops suitability is an effective way of bringing all related datasets together to support agricultural research and decision making. The main recommendation was that agricultural students must develop a comprehensive GIS database that will include all datasets relevant to soils and crops studies and management.
