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.
Land application of manure and other organic materials supplies much N to Nebraska’s crop production. In contrast to most other nutrients applied in organic materials, the availability of manure-N and its fertilizer-N substitution value is not well-predicted.
The practice of OT once in 5 to 10 years or more is not likely to adversely affect no-till systems. However, to be beneficial, the OT has to be well-planned and implemented to target a well-characterized problem such as a weed control or compaction problem.
The leaching of nitrate to groundwater and the increasing occurrence of groundwater with excessive nitrate levels for human consumption is a major concern in Nebraska. The amount of leached NO3- depends on soil NO3- concentration at different soil depth layers and the quantity of water movement downward through these soil layers to beyond the root zone.
