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.
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.
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.
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.
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.
This article addresses nitrogen application options for corn and availability of P and K from land-applied grain and fodder damaged by flooding. It supplements the previous article, Nutrient Management Issues for 2019.
