Figure 1: Bacteria (small rod-like structures) and fungi (larger spherical shapes) associated with the surface of a root (rhizoplane) readily use organic substances released by the plant as sources of food and energy for mediating many biochemical processes and to maintain dense communities in the rhizosphere. Note the non-random distribution of bacteria showing concentration of cells on the rhizoplane where several processes take place including nutrient transformation, synthesis of plant growth-regulating compounds and antibiotic production for protection from attack by pathogenic microorganisms.

Soil Health, Quality & Microbial Diversity

Soil health and soil quality have evolved as important concepts as we continue to expand our understanding of soil as the vital factor for vigorous plant productivity. These concepts have also stressed our awareness that soil is indeed a limited non-renewable resource that requires deliberate stewardship to avoid or minimize its degradation.

Proper Digestion Central to Health

Old wisdom suggests that to understand something our best bet is to simply be open to what it is telling us, with all of our senses. Use eyes, ears, smell, taste, touch, along with intuition, to notice the obvious — and trust our own perceptions. With the digestive system, or gut, its central location should […]

Key Stages of Resilience for Plant Health

Our vision and our mission is to help farmers produce healthy crops which are insect and disease resistant and have no need for toxic insecticides and fungicides. We can accomplish this goal by providing farmers with knowledge of how diseases and insect pests interact with growing plants, tools to monitor crop health in the field, […]

No-Till Growing: Vegetable Production

To limit soil damage, reduced tillage was steadily adopted over the years. This took the form of permanent bedding and wheel tracks with chisel plowing and very shallow rototilling of the bed surface. We then moved into prepping the beds’ surface with harrows only: disc, spring-tooth and rod weeders, combined with a roller.

the year two spring rye crop — note how few weeds are present. This rye grew well during the spring and early summer,
and was ready for harvest in mid-July. At right shows the rye straw after the grain was combined. Yields were about 35 bushels/
acre of rye seed the first year and 4 bales of straw/acre. This year, the yield was 52 bushels/acre of rye seed and 8 bales of straw/acre.

Transitioning to Organic: Strategies for Success

With conventional prices for corn, beans, wheat and dairy really low right now and both prices and demand for organic products high, a lot of growers are thinking about transitioning to organic. For most growers, one of the biggest deterrents to going organic is the 36-month-long process of transition, during which time you can use […]
