Information for those considering growing hemp for fiber or grain in Nebraska, including a Q&A and sample production budgets from other states.
Hemp Production in Nebraska
July 30, 2019
Is hemp on your horizon as a new crop for your rotation? In this, the first of three stories on the topic in this week's CropWatch, two agronomy professors outline key production information, often drawn from research in other states and countries.
Hemp Production for CBD
July 30, 2019
Research from other states and countries offers some insight into practices for growing CBD hemp in Nebraska. CBD hemp is a high-value crop that's labor-intensive and often grown more as a horticultural than as an agronomic crop.
Nutrient Management Suggestions for Corn Updated in EC117
July 9, 2019
The Nebraska Extension Circular, Nutrient Management Suggestions for Corn (EC117), has been updated to account for residual soil nitrate-N and provide an alternative for determining fertilizer-P rates.
In-season Nitrogen Management for Corn in 2019
June 12, 2019
Spring weather has complicated nitrogen management this year, making in-season nitrogen application necessary in many fields. You can estimate N needs with the Late Spring Soil Nitrate Test or by use of crop canopy reflectance sensing, both of which are addressed here.
Improving Manure Nitrogen Use Efficiency
April 18, 2019
A multi-year study of organic N used in Nebraska crop production validated sensor guided in-season N application as a means to efficiently use the N available from manure and other organic materials. See what benefits they found, as well as considerations for use.
