Phytosphere Research specializes in the design and execution of applied plant
science research projects. We employ the most appropriate and effective methods
possible to address the specific needs of any project we undertake, including
aerial photogrammetry, field survey, specialized measurement and assessment
techniques and equipment, and laboratory analysis. Using database management,
statistical analysis, GIS, and graphical data presentation software, we can
handle complex study data. Reports and data summaries are tailored to the needs
of our clients.
Phytosphere Research also provides consulting and research services to address
more immediate information needs. We provide tree and vegetation resource assessments,
soil nutrient analysis testing and recommendations, technical reviews, field
and lab services for diagnosing and remedying plant health problems, training
and educational presentations, and other services.
