Extremely toxic to both animals and humans, poison hemlock can be found statewide in Nebraska and is most toxic right before the fruits mature.

With this deficit in mind, extension educators stress the importance of taking inventory of feed and hay resources, and to begin planning for next year's needs right now.

Historical crop progress data for Nebraska is available at USDA. (Photo by Gary Stone) Sorghum and dry edible beans have returned to near-average planting pace thanks to a surge in fieldwork last week, and more than 90% of planted corn and soybeans have emerged in Nebraska.

Historical crop production reports for Nebraska are available at USDA. Nebraska's 2023 winter wheat crop is currently forecast at 33.0 million bushels, up 26% from last year's crop.

Whitish spots (stippling) are an indication of black grass bugs feeding, which can be managed by intense spring and fall grazing, hay removal, and foliar insecticides for severe infestations. (Photo courtesy Whitney Cranshaw, Colorado State University) This week — irrigation strategies for moisture-stressed alfalfa prior to first cutting, controlling black grass bugs in wheatgrass, and techniques for stretching pasture.

Nebraska Extension Weed Management Specialist Amit Jhala discusses the effect of dry soil conditions on activation of residual herbicides in corn and what can be done to control weeds.

With the arrival of severe weather season, N Field Observations highlights the importance of reviewing and updating insurance policies for your ag operation.

Figure 1. Early installation of sensors helps minimize root and leaf damage and makes it easy to get around the field with the pickup or ATV to install the equipment. Many producers in Nebraska will need to irrigate in June to refill the soil profile before high water demand begins in July, but there are numerous factors to consider when calculating the appropriate irrigation amounts.

Prolonged and extreme drought conditions have increased the potential for problematic grasshopper populations this growing season. Producers seeking information about grasshopper control can contact their local extension educator for more assistance. (Photo by Troy Walz) Prolonged drought conditions have increased the potential for problematic grasshopper populations this growing season, particularly for counties in the western two-thirds of Nebraska.

Registration is due by June 16 for all the workshops, which will cover the application process and eligibility requirements for USDA insurance programs and explain how they can be used to mitigate price risk. (Center for Ag Profitability photo) Specific insurance programs that will be covered during the workshops are Pasture, Rangeland, and Forage (PRF), Livestock Risk Protection (LRP) and Annual Forage insurance (AF).

Though most of western Nebraska is now free of drought or in moderate drought, recent rainfall hasn't been sufficient to improve eastern Nebraska's exceptional drought status, and annual rainfall deficits continue to escalate for the area.

Nebraska researchers evaluated two no-till, non-irrigated cropping systems from 2018 to 2020 to compare the effects of livestock grazing in a corn-soybean and corn-soybean-wheat rotation on crop productivity.

When irrigating fields early due to drought, the most reliable method to know when and how much to irrigate is to monitor soil moisture at multiple depths. For producers who are irrigating early this year due to drought, it's critical to monitor soil moisture to balance crop needs with the risk of losing nitrogen and other valuable crop inputs, and also to avoid the expense of over-irrigating.

Historical crop progress data for Nebraska is available at USDA. As of June 4, progress on sorghum and dry edible bean planting was significantly behind last year's pace, and soybean planting was nearly finished.
