Heavy covers on paddocks can be a challenging dilemma for farmers and landowners. While lush grassy paddocks may seem good for grazing, excess growth can lead to a host of problems. As the grass becomes too tall and thick, it can be difficult for livestock to graze effectively, and it may also hinder germination of new seedlings. On the other hand, mowing the paddock too early can be a missed opportunity to allow for further growth and production. Thus, the question remains: graze, sow, or wait and mow? This article will explore the pros and cons of each option and offer guidance for managing heavy covers on paddocks.
Due to continuous wet weather in March and April, some farms in certain areas of the country have not been able to start grazing this spring. In this situation, there may be large grass covers on parts of their farms.
For farmers with heavy grass covers, they have three choices: graze it off, mow it when conditions allow, or sow fertiliser and take a cut of silage in 6-8 weeks. Where there is low silage supply, farmers will prefer getting their stock to graze these areas when conditions allow. Alternatively, some may apply fertiliser (if not done already) and secure a cut of silage for May.
Another option worth considering is to leave these heavy covers of grass for 10-14 more days and secure an early crop of bales when conditions allow.

Met Éireann has forecasted mellower and more consistent weather conditions for early next week. When the weather becomes warm, dry, and sunny, ground conditions will improve, and these grass covers can be secured for winter feed.
Before making any decisions, farmers should walk their land to assess grass covers and identify paddocks that may have become too strong for grazing and could be marked for an early cut of silage. The fields should be closed for first-cut silage, and fertiliser should be applied (once ground conditions permit) if not yet done.
Remember, in six weeks (on Friday, April 14), it will be May 26, and in eight weeks, it will be June 9.
When fertiliser is applied to first-cut silage, it’s advised that the field receives 100 units of nitrogen (N)/ac from chemical fertiliser, slurry, or a mixture of both. Ideally, slurry would have been spread earlier in the drier conditions of February. At this stage, slurry could not be spread on first-cut silage grounds due to time constraints, so farmers should check their soil tests to see the level of phosphorus (P) and potassium (K) needed and remember the purchasing rules for chemical P and K fertiliser.
In conclusion, deciding whether to graze, sow, or wait and mow heavy covers on paddocks ultimately depends on your individual farm and herd needs. While there are benefits and drawbacks to each option, it’s important to consider the timing, type of grass, and animal grazing behavior to make the best decision for your operation. By carefully managing heavy covers, you can promote healthy soil, efficient forage utilization, and maximize the productivity of your land. Don’t be afraid to experiment with different strategies and consult with experts in your area to find the option that works best for you.
