​Purdue Extension is starting the Indiana Food Hub Network this year. So what’s a food hub?

What they have in common is that the tomato plants are not thriving after transplanting. It may be hard to say exactly what is going on with each of these, but it would not be surprising if they were cases of over application of a fertilizer or soil amendment, leading to toxicities for the plant. Ammonium toxicity is common when soil is cool and wet, soil pH is low, and there is[Read More…]
