Modern maize (Zea mays L.) hybrids coupled with improved agronomic practices may have influenced the accumulation and partitioning of nutrient uptake since the last comprehensive studies were published. The objective of this study was to investigate nutrient uptake and partitioning among elite commercial germplasm with transgenic insect protection grown under modern management practices. Plants were sampled at six growth stages and divided into four fractions for nutrient determination. Total nutrients required per hectare to produce 23.0 Mg ha-1 of total biomass with 12.0 Mg ha-1 of grain included 286 kg N, 114 kg P2O5, 202 kg K2O, 59 kg Mg, 26 kg S, 1.4 kg Fe, 0.5 kg Mn, 0.5 kg Zn, 0.1 kg Cu, and 0.08 kg B. A 10-d period (V10-V14) denoted the maximum rates of accumulation on a per day basis for dry weight (439 kg), N (8.9 kg), P2O5 (2.4 kg), K2O (5.8 kg), Mg (2.2 kg), S (0.7 kg), Zn (14.2 g), Mn (18.0 g), B (3.3 g), Fe (95.3 g), and Cu (3.0 g). The majority of total uptake occurred post-flowering for P, S, Zn, and Cu. Harvest index values of P (79%), S (57%), Zn (62%), and N (58%) were identified in the grain. These results provide much needed data on the nutrient uptake and partitioning of current hybrids, and provide an opportunity to further refine fertilizer method and timing recommendations for maize biomass and grain production. © 2013 by the American Society of Agronomy.

It is widely accepted that yields decline when corn (Zea mays L.) is grown continuously vs. in rotation wiThsoybean [Glycine max (L.) Merr.], although causes for the yield reduction are unclear. The primary objective of this study was to elucidate the source(s) of the continuous corn yield penalty (CCYP). The experiment was conducted from 2005 to 2010 in east-central Illinois beginning wiThthird-year continuous corn (CC) or a soybean-corn (SC) rotation at six N fertilizer rates. Averaged across all years, yield at the agronomic optimum N rate for CC was 8.84 Mg ha-1 and for SC was 10.20 Mg ha-1, resulting in a CCYP of 1.36 Mg ha-1; values ranged yearly from 0.47 to 2.23 Mg ha-1. Using a regression model, three signifi cant and independent predictors explained >99% of the variability in the CCYP: unfertilized CC yield (0NCCYD), years in CC (CCYRS), and the difference between CC and SC delta yields (maximum yield - Unfertilized yield) (DELTADIFF). The strongest predictor, 0NCCYD, reflects net soil N mineralization and demonstrates that it decreases in CC systems. The CCYRS was strongly and positively correlated wiThCCYP, indicating that the CCYP increased through Year 7. We believe that CCYRS measures the effects of accumulated corn residue in CC systems. Finally, we consider DELTADIFFto be a measure of the interaction between yearly weather patterns and crop rotation, which results in more negative yield responses for CC than SC under hot or dry conditions. This study concluded that the primary causative agents of the CCYP are N availability, corn residue accumulation, and weather. Source

A granulated fertilizer having a primary nutrient and a micronutrient and related methods of making. The micronutrient is incorporated into the fertilizer mixture by dissolving a compound form of the micronutrient into a feed stream for the formulation of the fertilizer material, a water return stream for the scrubbing of waste gas, and/or a feed stream for back titration of the fertilizer material.

A fertilizer composition including a base fertilizer granule with a barrier coating and one or more micronutrients. The base fertilizer material is coated with a barrier coating, and then a coating of one or more micronutrients. Alternatively, the base fertilizer material is coated with a barrier coating having discrete particles of micronutrients dispersed throughout. The barrier coating acts to physically and chemically isolate the micronutrient particles from the underlying fertilizer composition such that more of the micronutrient is available to the soil solution, and ultimately to the root zone of the plant.
