1. Effects of Residue Placement on Co2 Loss in an Irrigated, No-till Corn SystemIt is well known that residue management practices that leave crop residue on the surface, such as no-till agriculture, promote soil fertility. However, the effects of such practices on carbon sequestration can be highly variable. To better understand how residue management impacts the loss of carbon through mineralization, we investigated the effects of residue location and addition on CO2 produced from residue decomposition under no-till irrigated continuous corn in Northern Colorado. Over... H. Oleszak, F. Cotrufo, S. Leichty, C. Stewart |
2. Effect of Foliar Zinc Application on Durum and Spring Wheat Grain Yield and QualityZinc (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 included... F. Etemadi, R.

3. Stacking Nutrient 4Rs on Potato and WheatThe 4 Rs of nutrient management are a set of research-based guidelines for farmers to use when applying fertilizers to their crops. The aim of the 4 Rs is to improve the sustainability of major cropping systems and the environment without compromising crop yield and quality. The objective for this project is to evaluate individual and stacked 4 R management practices and how they intersect. We conducted this experiment on a Russet Burbank potato crop grown at a field near Grace, Idaho in 2020.... S.H. Stapley, N.C. Hansen, M.A. Yost, E.A. Woolley, B.G. Hopkins |
