A snapshot in time: assessing your pasture mid-season

Source: Saskatchewan Agriculture and Food

The health of your pasture is determined by its ability to perform important ecologic functions. The production of forage for livestock, the protection of the site from soil and water erosion, the cycling of nutrients and energy, and the capture and release of water are examples of the benefits a healthy pasture provides for society.

Maintaining a healthy pasture means sustainable grazing opportunities for producers. But it’s not something producers can simply take for granted. They will want to monitor their pastures from time to time and conduct health assessments to ensure they are properly managing the land to achieve its full potential.

According to Jodie Horvath, a livestock development specialist with Saskatchewan Agriculture and Food (SAF), conducting a health assessment is like taking a snapshot of your pasture. It can help identify problem areas, such as patches of invasive weeds, uneven distribution of cattle throughout a paddock and damage to sensitive water sites.

“The first step in improving management is being aware of the issues,” Horvath said. “This allows a producer to make changes while it is still manageable. A quick survey of your pasture tells how your management has impacted a particular site.”

Take a closer look at your pasture. Are the types of grass you seeded present? In a tame pasture, you want the species you have introduced to be dominant. However, you can expect composition to change over time and with variable weather conditions. The SAF publication, Field Guide: Identification of Common Seeded Forage Plants of Saskatchewan, can help you identify the forage species that are in your pasture.

Take note of the weeds. What are they and how are they distributed around the pasture? Do you remember seeing them last year? Are they in solid patches or scattered throughout the field? Thriving weeds may be a sign that your seeded forage lacks the vigour to compete effectively against the weeds. Weeds are invasive by nature, so any bare ground provides opportunities for them to establish. Two SAF publications, FAQ: Identifying Weeds (Broad-leafed) and FAQ: Control of Selected Weeds on Pastures and Hay Land in Saskatchewan, can be found on the SAF website at www.agr.gov.sk.ca.

What do you see when you look down at the ground? The dead and decaying plant material from last year is litter. Litter performs an important function in your pasture by enhancing forage production through water, mineral and nutrient cycling. It protects the soil against wind and water erosion, and buffers against dry conditions by aiding moisture retention and reducing soil moisture loss.

It is important to monitor your pasture throughout the season, as well as from year to year. Identifying trends and patterns lets you know if the management decisions you made are working, or if you need to make some changes.
