Corn Residue Harvesting Effects On Yield Response To N Fertilization, Jose L. Pantoja, John E. Sawyer, Daniel W. Barker, Mahdi Al-Kaisi
Corn Residue Harvesting Effects On Yield Response To N Fertilization, Jose L. Pantoja, John E. Sawyer, Daniel W. Barker, Mahdi Al-Kaisi
John E. Sawyer
Producers have many choices of diverse tillage practices for their corn (Zea mays L.) production systems. However, no-till has become an important soil management practice to help reduce water and wind erosion, as well as nutrient runoff, while conserving soil moisture for crop use. No-till systems also help farmers by saving labor and time, as well as reducing farm costs due to less equipment and fuel consumption. Nevertheless, no-till production is typically more successful and has higher crop yield on moderately to well drained medium-textured soils (Bitzer, 1998), compared to soils with poor internal drainage and high clay.

Evaluating The Interaction Between Chelated Iron Source And Placement On Phosphorus Availability In Soybean, C. L. Edwards, D. Ruiz Diaz
Evaluating The Interaction Between Chelated Iron Source And Placement On Phosphorus Availability In Soybean, C. L. Edwards, D. Ruiz Diaz
Kansas Agricultural Experiment Station Research Reports
In agriculture, chelating agents are used to supplement micronutrients, such as iron (Fe). However, little research has been conducted at the field-scale level to evaluate chelating agent effects on phosphorus (P). The objectives of this study were to evaluate three commercially available chelated Fe sources on early soybean growth and nutrient uptake. The study was conducted at six locations in 2014 and 2015. The experimental design was a randomized, complete block with a factorial treatment arrangement. The two factors included fertilizer source and fertilizer placement. The fertilizer sources were P only, EDTA-Fe, HEDTA-Fe, and one glucoheptonate product, Cee*Quest N5Fe758 (CQ-758), …
Evaluation Of Tillage, Crop Rotation, And Cover Crop Impacts On Corn Nitrogen Requirements In Southeastern South Dakota, Sara Louise Berg
Evaluation Of Tillage, Crop Rotation, And Cover Crop Impacts On Corn Nitrogen Requirements In Southeastern South Dakota, Sara Louise Berg
Electronic Theses and Dissertations
Nitrogen (N) is a vital factor of corn (Zea mays) production. Previous work in South Dakota has shown that there is uncertainty as to whether nitrogen requirements are the same for corn raised under no-till (NT) versus conventional till (CT) production systems. The objective of this study was to evaluate whether N requirements continue to be greater under long-term NT versus CT production systems in southeastern South Dakota, while also considering effects from cover crops and crop rotation. This was a two year study conducted at the SDSU Southeast Research Farm near Beresford, SD; it was superimposed on a long-term …
Evaluation Of Phosphorus Source And Chelate Application As Starter Fertilizer In Corn, C. L. Edwards, D. Ruiz Diaz
Evaluation Of Phosphorus Source And Chelate Application As Starter Fertilizer In Corn, C. L. Edwards, D. Ruiz Diaz
Kansas Agricultural Experiment Station Research Reports
The differences between common phosphorus (P) fertilizers as a starter in corn production have been studied for many years. However, little research has been conducted showing which P fertilizer sources are most effective with varying compositions of ortho- and poly-phosphate. The objectives of this study were to evaluate three commercially available P fertilizers, 0-16-19, 10-34-0, and 0-18-18 (N-P2O5-K2O) as starter band with and without the addition Cee*Quest-70 (CQ-70), a glucoheptonate chelate. The study was conducted at two locations, Scandia and Rossville, in 2014 and 2015. Experimental design was a randomized, complete block with four …
