Quick Answer
Heavy browsing on food plots can lead to a decline in overall plot health, reduced seed germination, and decreased crop yields. Excessive grazing can also trigger the release of allelochemicals, which can inhibit seedling growth. This can result in a weak stand and reduced nutritional value for deer.
Effects on Seed Germination
Heavy browsing can physically damage seeds, disrupt soil chemistry, and alter the soil’s pH levels. This can reduce seed germination rates by up to 30%. To mitigate this, it’s essential to plant seeds at the correct depth (typically 1/8 inch for clover and 1/4 inch for brassicas) and maintain a consistent soil moisture level. Using a soil test kit can help identify any pH imbalances, allowing for timely adjustments.
Brassica and Clover Selection
When selecting brassica and clover varieties for heavy-browsing areas, opt for species that are more resistant to grazing pressure. For example, ‘Purple Top’ turnips and ‘Tiger’ type radishes are known to be more resilient than other varieties. In clover, ‘Microclover’ and ‘Durana’ are popular choices due to their tolerance to grazing and ability to regrow quickly.
Timing and Soil Preparation
Timing is critical when planting food plots in areas with high browsing pressure. Planting in late summer or early fall (after the deer have fed on summer growth) can help minimize the impact of heavy browsing. Before planting, ensure the soil is properly prepared by incorporating a 2-inch layer of compost or well-rotted manure. This will help to create a nutrient-rich environment and promote healthy seedling growth.
