Research from M. Sharifi and co-authors yields new data on potato research.(Report)

According to recent research published in the American Journal of Potato Research, "Nitrogen (N) supply from organic sources to the potato (Solanum tuberosum L.) crop is difficult to predict and to synchronize with crop demand."

"In this study, Plant Root Simulator ™ (PRS ™) probes were evaluated as a tool for prediction of N supply from two rates (300 vs. 600 kg N ha(-1)) of either a hog manure-sawdust compost (HMC) or a pelletized dehydrated poultry manure (NW) in Atlantic Canada. The cumulative PRS mineral N supply rate (PRS-N) measured for the period of 31 days after planting (DAP), soil mineral N at 10 DAP and soil NO3-N at 31 DAP were closely related …
