>>In particular, vascular-arbuscular mycorrhizal fungi (VAMF) increase yield in peppers grown in low-phosphorous or low-moisture soils.<< The key phrase here is "low phosphorous" as well as the combining pepper culture with that of tomatoes. While peppers and eggplant are in the same general family, there is danger in grouping their culture. The most common way to get the best in production from tomatoes is to use a high phosphorous, low nitrogen fertilizer. 5-10-5 seems to be the most popular. Even the VAMF sellers say it should not be used in conjunction with the high phosphorous fertilizers such as 5-10-5 that are normally used with tomatoes. Hi Phos. fertilizers and VAMV combined may very well burn the roots off your new transplants. Good gardening, Chuck Wyatt
