3 min read

In this article, you will discover how the SOHMA KIT® makes soil health testing easy, affordable, and accurate. This makes it perfect for home gardeners, farmers, and anyone practicing sustainable gardening or regenerative agriculture. Please follow through with the article.


SOHMA KIT: A Simple Way to Test Soil Health at Home or on the Farm

Healthy soil is the foundation of any thriving garden or productive farm. However, to check the health status of if it’s in good form usually involves expensive lab testing. Until now.

Thanks to the SOHMA KIT® (Soil Health and Management Assessment Kit). With SOHMA KIT®  you can now test your soil health quickly and affordably, right on-site. Whether you’re growing vegetables in your backyard or managing a small farm, this new tool makes understanding your soil easier than ever.


🌱 What Is the SOHMA KIT?

The SOHMA KIT® is simply a portable soil testing kit designed for on-farm and in-garden use. It allows gardeners and farmers to measure seven key indicators of soil health. SOHMA KIT® does not require any lab work to be done.

The kit checks for:

  • Soil water infiltration (how fast water soaks in)
  • Soil structure and aggregate stability (how crumbly or compact it is)
  • VESS (Visual Evaluation of Soil Structure)
  • Soil pH levels
  • Soil macrofauna (like earthworms and other beneficial critters)
  • Catalase enzyme activity (a biological marker of soil life)
  • Biogenic aggregates (natural clumps formed by soil organisms)

These factors are combined to produce a Soil Health Index (SHI). SHI score helps you understand how healthy your soil is. Unlike other soil test kits that measure soil properties individually, SOHMA KIT integrates all indicators into one.


Why Is the SOHMA KIT Important?

Healthy soil leads to stronger plants, better yields, and more resistance to pests and drought. Until now, soil testing has been too complex and costly for many growers.

But the SOHMA KIT changes that. It’s:

  • User-friendly
  • Budget-friendly
  • Quick to use
  • Designed for topsoil assessment

Recent research by Schiebelbein (2025), has shown that SOHMA KITs work really good. Studies conducted in Brazil showed that the SOHMA KIT® produced results similar to standard lab tests. Especially for important indicators like pH and infiltration rate. In addition, farms using cover crops have been found to have improved their Soil Health Index by 35%. Is that not impressive?


🏡 Benefits for Home Gardeners and Small Farmers

If you’re a home gardener, urban farmer, or sustainable grower, the SOHMA KIT® can help you:

  • Identify problems like soil compaction or poor drainage
  • Choose the right soil amendments or fertilizers
  • Monitor improvements after adding compost or using cover crops
  • Support regenerative gardening practices

Whether you’re growing herbs in containers or managing raised beds, the ability to assess your soil health gives you a huge advantage.


⚠️ A Few Things to Keep in Mind

The kit is best used on topsoil and does require some basic training, especially for evaluating the soil visually. It’s far more accessible than traditional testing methods.  In addition, perfect for hands-on gardeners and DIY soil testers.


🌾 Bottom Line: The Future of Soil Health Testing

The SOHMA KIT® makes soil testing practical, affordable, and accurate. No lab work is needed. It’s a smart tool for anyone looking to improve soil quality, grow healthier plants, and garden more sustainably.
