SEO Content & Blog writer | Editor& Proofreader |Agric Scientist

Need content that's technically accurate, genuinely well-researched, and built to rank? I'm a published agricultural scientist with 35+ years of hands-on research and field experience — not a generalist writer guessing at agricultural topics. I write SEO-optimised articles and blog posts for agricultural businesses, gardening brands, and sustainable farming organisations that need content readers (and search engines) can actually trust. I use modern AI tools to work efficiently, but every fact, every claim, and every technical detail is verified and refined through my own research background — soil water science, crop simulation modelling, and decades of practical farming experience. You get speed without sacrificing accuracy. I specialise in: Moringa cultivation and commercial production Soil health and soil-building practices Sustainable and regenerative agriculture Crop production and agronomy Irrigation and water management Small-scale farming and homesteading Vegetable production and home gardening Agricultural research and technical articles Background: Senior Agricultural Research Technician (Agricultural Research Council), published researcher (South African Journal of Plant and Soil, 1997), international agronomy experience across South Africa and the US Midwest. Skills: Crop Modelling, Soil Water Science, Micrometeorology, Evapotranspiration Analysis, Biological Simulation, Sustainable Agriculture, SEO Content Writing, Technical Writing
