Nutrient management and crop quality clearly go hand in hand. But not always in the ways you might think.

In my nutrition management work, I have focused on understanding how to manage nutrition at different stages of fruit development to affect fruit quality. I have learned that it is relatively easy to substantially impact fruit size, firmness, sugar and solids content, shelf life, and storability with nutrition management. Many of these improvements in fruit quality are in some way associated with calcium metabolism in the fruit.

Oregon orchardist Mike Omeg will test a soil and plant nutrition program developed by an Amish farmer with an eighth grade education who has become one of the country’s leading advocates of alternative farming methods.

Omeg, who grows cherries near The Dalles, will work with Oregon State University and Washington State University staff on a three-year grant provided by the USDA’s Natural Resources Conservation Service. They’ll compare parts of the orchard managed with conventional, industry-standard methods to sections operated with what Omeg described as “intensive nutrient management” of the soil and trees.
