Summer Pasture for Horses

With pastures greening up well across the county, it is time to start planning ahead with summer pasture needs for your horses.

Pasture provides a significant percentage of horses' nutrient needs.  Although horses have more grass than they can consume in the spring when moisture is adequate, the hot and dry conditions of summer greatly reduce available pasture.  Good management is the key to getting through this growth slump.

Weed Watch: Poison Hemlock

Last week, we focused on yellow buttercup emerging in fields and pastures.  This week, let us take a closer look at another weed that we may be seeing on the farm--poison hemlock (Conium maculatum).

Although this plant is often seen along roadways, abandoned lots, fence rows, and other non-cropland sites, in more recent years, poison hemlock has expanded into grazed pasture lands and hay fields.  The concern not only stems from its invasive nature, but the fact that it is one of the most toxic plants in the world.

Poison hemlock is classified as a biennial that reproduces only by seed.  Flowers and new seed are typically produced in late May and June.

Weed Watch: Yellow Buttercup

One of the signs that spring has arrived is when yellow buttercups begin to appear, but it is during the winter months that the vegetative growth of buttercup actually takes place.

As a cool-season weed, this plant often flourishes in over-grazed pasture with poor stands of desirable forages.  In fact, many fields that have dense buttercup populations are fields heavily grazed by animals during the fall through the early spring months.

Buttercups are sometimes classified as short-lived perennials, but often grow as winter annuals.  Plants typically produce five, shiny yellow petals in the early spring.

Tips to Prevent and Improve Soil Compaction

Soil compaction is a common problem that many producers face, but is often overlooked.  Significant soil compaction can reduce forage yields and slow forage establishment.  Management practices can be used to reduce and correct this problem while improving soil conditions.

Compaction results when soil particles are pressed together, reducing pore space and aeration.  The damage to the soil structure reduces the soil's ability to hold and conduct water, nutrients, and oxygen.  Rate of water infiltration is decreased and more water is lost to runoff.  Other effects of compaction include decreased organic matter, reduced microbial activity, poor drainage, increased erosion, and nutrient leaching.
