Horizon Point


Example Report

The emailed reports contain weather information and advisories selected by the farmer. The email is purposefully simple with few images so that it will quickly download for farmers with slow internet connections. The example below contains a real report for a specific date and location. In addition to the weather information and management advisories, it lists the reports which are not in season and which the subscriber has chosen not to receive.

Spring Planting Soil Temperature Chart

Soil Temperature Chart (available on-line only)

Soil temperature, not air temperature, controls germination of seeds. Soil temperature needs to be above 50°F for corn to germinate and 60°F for soybeans to germinate. Optimum temperatures for germination are higher.

Horizon Point Weed Scouting Aid

This information should be used as a general guide to aid in weed scouting and weed management decisions. These calculations are based on the ambient air degree days accumulated since January 1. Additional factors, such as the soil type, amount of rainfall received, and the presence of crop residue will have a significant impact on the likelihood of weed emergence in a given situation.

The following weeds could have emerged in your area recently:

Pennsylvania smartweed, Common sunflower, Giant ragweed, Common lambsquarters, Giant foxtail, Common ragweed, Velvetleaf, Woolly cupgrass
The following weeds could be emerging in your area by the date given.

The Rainfall Index Monitor report is designed to assist understanding the rainfall index used to calculate indemnities paid through the Pasture, Rangeland and Forage (PRF) Insurance program. PRF Insurance is administered through the USDA Risk Management Agency (RMA).

The rainfall index is based on data from the National Oceanic and Atmospheric Administration (NOAA) Climate Prediction Center (CPC) that is specific to grid locations. Each grid area is 0.25 degrees in latitude by 0.25 degrees in longitude. The rainfall index is interpolated from data from multiple weather stations by the CPC.

It is important to note that daily CPC rainfall reported for Missouri covers a 24 hour time period of 7:00 a.m. to 7:00 a.m., during daylight savings time (6:00 a.m. to 6:00 during standard time). If you check your rain gauge in the morning, you will be able to closely monitor any differences between your measurements at home and interpolated data provided by NOAA.

Under the Current Interval Estimates heading, there are three items reported. “Accum” is the accumulated precipitation during the selected two month period for a specific grid point in the PRF program. “Avg” is the long term average for the same two month period and grid point. Those two numbers are used to calculate the “Index” number. At the end of the interval’s time period, the “Index” should be the same index number used by RMA to calculate indemnities for those signed up for PRF insurance.
