If you add lime, you&rsquo;ll see a change in the pH timeline. If you stop adding Mn, you&rsquo;ll see a change in the Mn timeline. And this goes for particle size timelines too.</p> <p>After the organic material is measured in an OM246 test, the remaining mineral matter from the 0&ndash;2 cm layer of the rootzone can be passed through sieves to measure the particle size distribution.</p> <p>In 2025, a golf course with a multi-year history of 0&ndash;2 cm layer particle size analyses changed to a new topdressing sand. The sands used in recent years are shown in the image below.</p> <figure > <div class="d-flex justify-content-center"> <div class="w-100" ><img alt="" srcset=" /post/particle-size-detective-work/featured_hu63b4c2ad2ad12f146e6768c735e7f135_423859_d1b16ffd16fc759585a14669ccb3567f.webp 760w, /post/particle-size-detective-work/featured_hu63b4c2ad2ad12f146e6768c735e7f135_423859_994c1ac6a585372d4223004ff8536bf6.webp 1200w, /post/particle-size-detective-work/featured_hu63b4c2ad2ad12f146e6768c735e7f135_423859_1920x1920_fit_q80_h2_lanczos.webp 1920w" src="https://www.asianturfgrass.com/post/particle-size-detective-work/featured_hu63b4c2ad2ad12f146e6768c735e7f135_423859_d1b16ffd16fc759585a14669ccb3567f.webp" width="1200" height="900" loading="lazy" data-zoomable /></div> </div></figure> <p>That change in sand was easily picked up by the particle size analysis of the OM246 samples collected in early 2026.</p> <figure > <div class="d-flex justify-content-center"> <div class="w-100" ><img alt="" srcset=" /post/particle-size-detective-work/very-fine-sand-increase_hu0a9e7963f5627444452c8c37fa36e923_148744_164dec9d10e05f929ec950db8230c678.webp 760w, /post/particle-size-detective-work/very-fine-sand-increase_hu0a9e7963f5627444452c8c37fa36e923_148744_28ba935f52bf9014f5c11bbe7a2454da.webp 1200w, /post/particle-size-detective-work/very-fine-sand-increase_hu0a9e7963f5627444452c8c37fa36e923_148744_1920x1920_fit_q80_h2_lanczos_3.webp 1920w" src="https://www.asianturfgrass.com/post/particle-size-detective-work/very-fine-sand-increase_hu0a9e7963f5627444452c8c37fa36e923_148744_164dec9d10e05f929ec950db8230c678.webp" width="1200" height="741" loading="lazy" data-zoomable /></div> </div></figure> <p>The increase in very fine sand hasn&rsquo;t caused any problems yet in terms of infiltration or surface performance. Changes in particle sizes at the top of the rootzone can be easily detected through this method.</p>
