Welcome to Javed Iqbal who recently joined the Department of Agronomy and Horticulture as an assistant professor for nutrient management and water quality. Iqbal will be conducting research and education on efficient uses of nutrients to enhance crop production and reduce environmental effects.
The impact on soil nutrient availability after the March snowmelt/heavy rainfall event is highly variable. The following describes what to consider in areas of little, moderate, and severe harmful effects.
University researchers will be conducting a two-year study to see how grain quality, yield, and field stands are affected by nitrogen fertilizer rates and application timing. The trials will be conducted across the state and with variations in the amount of precipitation received.
Recent heavy rains have many feedlot holding ponds full and operators looking for irrigation options to apply animal manure during the growing season. Here are some considerations for applying diluted animal manures without damaging the crop.
To differentiate sulfur deficiency from nitrogen deficiency in wheat, look for field patterns. Symptoms of yellowing limited to certain areas is more typical of sulfur deficiency. In addition, symptoms of sulfur deficiency are more conspicuous when soil temperatures are cold as in early spring.
The NebGuide, Nutrient Management in Organic Farming, features information also of value to conventional production, including manure management, composting, non-traditional products, and crop rotation suggestions.
Nitrogen is a key factor in farm management and economics. One of the most expensive inputs for corn production, it can be easily lost to the environment. One avenue for losing N, as nitrous oxide, has an impact on our climate as a greenhouse gas. Successful strategies for reducing N losses, especially as nitrous oxide, benefit both farmers and the environment.
