"Yellowing corn leaves are often a sign of a problem with the nutrient uptake process, either due to water competition from nearby grass or drought conditions. Corn plants get 13 of the 16 required nutrients for growth through the soil, either through direct contact as roots grow or via mass flow or diffusion. Both mass flow and diffusion require water in the soil to function."
"@Monica Pape, 'The Accidental Agronomist,' is an Army spouse who works with farmers across the country giving them a better understanding of their soil tests to help them implement sensible fertilization and management plans that produce higher yielding crops while saving money and being environmentally responsible. Attendees are invited to bring their current soil tests for brief consultation with Monica during the workshop."
