Revised Soil Fertility Recommendations for Corn

Fertilizer recommendations for corn were published about 40 years ago and have changed little since then. However, during the past 40 years, yield expectations have at least doubled from about 80 to more than 200 bushels per acre in many fields. Tillage practices and the hybrids planted also have changed. The changes from previous corn fertility recommendations are primarily the result of recent assessments of corn yield responses to nitrogen through field experiments using modern hybrids and conditions.

Scout for Banded Sunflower Moth

Integrated Pest Management scouts are detecting increasing numbers of banded sunflower moths in pheromone traps. Sunflower should be scouted for banded sunflower moth eggs or adult moths when most of the plants in the field are at plant stage R3 (distinct bud elongated ¾ inch above the nearest leaf, yellow ray petals not visible).

Soybean Root Rot

The wet spring has caused soybean root rot problems in North Dakota. Damping off and root rots can be caused by many different pathogens; Pythium species, Phytophthora sojae, Fusarium species and Rhizoctonia solaniUnfortunately, it can be very difficult to determine which pathogen is causing the primary disease.  In many cases, it is likely that multiple pathogens are acting synergistically to cause the damping off.

Managing Saline Soils

Saline soils have salt levels high enough that crop yields begin to suffer or cropping is impractical. Several factors contribute to the development of saline soils. A high water table is a prime requirement. Recognizing how and why salts accumulate is the first step in farming profitably on land interspersed with saline soils. Preventing further encroachment of salinity and addressing remediation strategies are other steps.

Weed Watch: Palmer Amaranth

Palmer AmaranthPalmer Ama

Palmer amaranth can produce millions of seeds per plant and grow baseball bat-sized stems that can stop combines. It has forced radical changes in weed control because of its relentless ability to reproduce and spread at astounding rates. The latest information shows that glyphosate–resistant Palmer amaranth is now present in every Midwest and Plains state except Minnesota and North Dakota. Palmer amaranth was chosen as North Dakota weed of the year as a proactive approach to increase awareness of its extreme noxious and pernicious capability, to aid in identification and to encourage land owners to keep a vigilant watch and kill all plants that may grow.

NDSU Research Extension Center Field Days

It is that time of year when NDSU Research Extension Centers across the state hold their annual field days. Field days are a chance for researchers and Extension faculty to share information on topics such as: ■ New crop varieties ■ Better production methods ■ Weed control ■ Soil health ■ Grazing intensity ■ Cattle nutrition and genetic disorders ■ Irrigation ■ Manure management ■ Precision agriculture ■ Biofuel development

Check Plant Density


Broadleaf crop plants have emerged or are just emerging, so this is the time to count the plants and calculate what percent of the seeds actually came up. The target live seed (those seeds that can germinate) planted and the seeds actually making it into an established plant can differ by 10 to 15 percent.

Many species of tall deciduous trees are available for conservation and urban plantings. The ND Tree Selector is an online tool that helps users choose tree and shrub species based on a variety of characteristics. Are you looking for something that is fast growing or a tree that is long-lived? Perhaps a species with pretty flowers?  The ND Tree Selector can help you find species to consider for your next planting.
