Leveraging AI to Evolve Soil Science for Dr Gordon Rajendram

BY PHONG MAI CHI

Dr Gordon Rajendram PhD, based in Hamilton, is one of New Zealand’s foremost soil fertility experts with over 35 years of experience in analytical testing, applied research, and independent consultancy. Renowned for developing field-calibrated nitrogen and sulphur soil tests used in the Overseer nutrient model, he builds trust through evidence-based advice on nutrient cycling, effluent reuse, foliar fertiliser, and soil health.

Synthesia AI is a generative video platform that converts text scripts into professional-quality videos using lifelike avatars and multilingual voiceovers, all without cameras or editing teams. It supports over 120–140 languages and offers consistent branded delivery across videos.

Educational Content Creation Opportunities

  • Soil Science Tutorials Dr Rajendram can transform key technical content, such as soil test interpretation, effluent management guidelines, and foliar fertiliser applications into short (1–3 min) explainer videos. These enhance comprehension for farmers and advisors, allowing them to visualise best practices and decision thresholds.

  • Seasonal Field Advice Series Based on his well- regarded monthly and seasonal newsletters, he could produce a regular video series (e.g. spring nutrient planning, winter foliar sprays, erosion mitigation). This helps deliver timely, actionable guidance in a more engaging format than text alone.

  • Client Onboarding & FAQs Instead of repeating the same explanations in person or by email, avatar-led videos can introduce his services, explain sample collection protocols, lab-reading steps, and highlight the value of foliar versus granular fertilisers.

Benefits Summary

  • Time & Cost Efficiency: Video generation takes minutes, and updates can be reused or localised for Māori and Pasifika audiences.

  • Consistency & Scalability: Every video reflects a uniform style, tone, and branding, reinforcing identity and aiding trust.

  • Accessibility & Reach: Multilingual videos and caption options expand viewership, improve SEO, and support inclusive outreach.

Recommendation: Begin by selecting two core topics such as "How to Read Soil Test Results" and "Winter Foliar Fertiliser Use" as well as drafting concise scripts using a burger-style structure (intro, explanation, call-to-action). Use Synthesia to generate initial videos, then host them on the website, embed into newsletters, and share via social platforms or farming groups.

By integrating Synthesia AI, Dr Rajendram can modernise his educational outreach and transform expert content into engaging, shareable, and scalable videos that strengthen his professional presence and impact in New Zealand agriculture.
