At the local market the other day, I was shopping for mangoes. Most of the mangoes I had recently were insect contaminated or partly rotten, even if they looked OK on the outside. Then on one table, I spotted a gorgeous mango for sale, so I enquired as to the farm from which it came. Turns out I had done soil analysis at that farm. This mango, pictured on the left, stayed good for a week in the refrigerator. It was perfect! It was sweet (high Brix level), and had great texture and flavor–perfect in every way. The mango on the right looked like most of the mangoes in this area–covered with a fungus called anthracnose (Colletotrichum gloeosporioides). When plants get the nutrients they need, they are much more disease resistant. They also more pest resistant, taste better, have a longer shelf life, and yield more abundantly.
