1. Effect of Foliar Zinc Application on Durum and Spring Wheat Grain Yield and Quality Zinc (Zn) deficiency represents a common micronutrient deficiency in human populations, especially in regions of the world where staple food crops are the main source of daily calorie intake. Micronutrients like Zn also plays an important role in growth and development of plant thereby affecting crop yield and quality. A two-year field trial was conducted at Sidney, Montana, to investigate the effect of foliar application of Zn on yield and grain quality of spring wheat. Zinc treatment i... F. Etemadi, R.

2. Assessment of Soil Testing As It Relates to Corn Ear Leaf Nutrition in the Midwest Soil testing for P, K and Zn for corn production the Midwest is based on the probability of crop yield response to an applied fertilizer and not on crop nutritional status. Results of three years of observational data from 98 field sites show soil test M3-K only predicted 26% of the variability in ear leaf K at growth stage R1-R2, whereas K base fraction (KBF) predicted 44% of the ear leaf variability and 56% of the variability in the ear leaf K:Mg ratio. Soil M3-P was inconsistent in predict... R. Miller Download paper
3. Managing Nutrients in Beef Feedlot Manure - Lessons from a 45-year Field Study The original objective of a long-term field experiment established in 1973 was to determine the safe loading capacity of soil with beef cattle feedlot manure. Manure was applied annually at 0, 30, 60, and 90 Mg ha-1 (wet weight) under rainfed and 0, 60, 120, and 180 Mg ha-1 under irrigated conditions. The long-term manure applications increased organic matter, nitrogen (N), phosphorus (P) and potassium (K) content and salinity in the soil, and barley forage yie... X. Hao Download paper
4. Rate and Depth of Liquid P Fertilizer Placement Affects Root Architecture and Arbuscular Mycorrhizal Fungal Associations in Grain Corn A two-site, two-year study was conducted on corn root response to liquid phosphorus (P) fertilizer applications as a function of rate and depth of placement. Corn planted into no-till at two locations (Thrall & Snook, TX) was fertilized with banded liquid P applied 15 cm off seed row at different rates and depths. The upper portion of the root systems were excavated along with all top plant matter at the V10 - V12 growth stage. Digital images of washed roots were analyzed for spatial dens... J.
