1. Corn Hybrids With Contrasting Root Systems: Response To Soil And Fertilizer PhosphorusWith current corn genetic improvements for water-limited scenarios, root system architecture and growth are being considered which may affect overall nutrient uptake particularly for immobile nutrients. The objective of this study was to evaluate plant response and phosphorus uptake with contrasting, generally shallow and generally deep rooted corn hybrids. Over the two years there were a total of seven sites, two sites in 2011 and five sites in 2012. The sites are all rain fed except for three sites... |
2. Conservation Practices Lower Soil Test Phosphorus Requirements and Optimize Crop YieldSustainable P management in cropping systems is a challenge in modern agriculture. The implementation of conservation practices of no-till, retaining high levels of residue in the field, and diverse crop rotations may create a more suitable environment for arbuscular mycorrhizal fungi (AMF) to accumulate. A greater AMF population may subsequently increase the P available to crops, lowering the soil test P amount needed to optimize crop yield. At the Dakota Lakes Research Farm in Pierre, South... C.
