Optimize Nodulation, Nutrient Balance, and Yield in Beans, Peas, Soybeans, Alfalfa & More
The Smarter Way to Manage Nutrition in Nitrogen-Fixing Crops
Legumes are unique—they fix nitrogen, enrich the soil, and support regenerative systems. But they still require balanced nutrition
to thrive. A deficiency in boron, molybdenum, potassium, or sulfur
can quietly limit nodulation, reduce growth, and shrink yields.
The Legume Plant Tissue Test
is specifically designed to help growers monitor and fine-tune nutrition in legumes by analyzing both leaf and petiole tissue. Whether you're managing beans, lentils, alfalfa, soybeans, or cover crops, this test gives you real-time data
you can act on mid-season.
