Have you heard about rock dust being used to increase yields and size  of crops?

Here’s a sampling quoted form Organic Connections

“half the  soil terrace we went with no rock dust and on the other half we put rock dust and had bigger plants and bigger crops on the rock-dusted side, bigger potatoes. we reckon we quadrupled the yield in comparison with the original soil, because not only did we have bigger potatoes but we had more of them.”
