Maize harvest

In recent visits to farms throughout the South West, one question continues to arise: “Which Sustainable Farming Incentive (SFI) action is best suited for maize?” A highly effective and rewarding action is the planting of winter cover crops following maize harvesting. This approach not only provides excellent payments per acre but also enhances soil health and helps in managing nutrient runoff. However, executing it successfully can present challenges, particularly surrounding the timely establishment of cover crops.

The Timely Establishment Challenge

Under the SFI framework, winter cover crops must be firmly established by mid-October. This step is crucial for ensuring that ground cover is adequate from early December through late February. Yet, the overlap of maize harvesting and planting a cover crop, such as winter cereal or Italian ryegrass, before the deadline can be complicated. Key factors include:

– Weather variability that can delay harvesting.
– Harvest timing that can be impacted by soil health conditions.
– The potential for adverse conditions in autumn limiting available harvest days.

The Key to Success: Variety Selection

Choosing the appropriate maize variety is fundamental to overcoming these obstacles. Although it may be tempting to opt for high-yielding varieties, these often present significant challenges. Here’s why careful selection matters:

Late-Maturing Varieties:
High-yielding maize varieties often mature later in the season, leading to various complications, such as:
– A reduced number of daylight hours available directly correlating with the harvest window.
– Elevated crop moisture levels which can raise drying costs.
– Potentially adverse autumn weather limiting the number of harvest days.
– The likelihood of wet soil conditions, increasing the risk of compaction during machinery use.
– Difficulty in establishing cover crops due to falling soil temperatures.

Feed Quality Concerns:

Harvest delays can also mean that maize is harvested below its nutritional peak, potentially diminishing the quality of feed due to weather constraints and the busy schedules of contractors in autumn.

The Advantages of Early-Maturing Varieties

Early-maturing maize varieties can significantly alleviate many of these challenges while providing several benefits for farmers in the South West:

1. Timely Harvest
Early-maturing varieties can be harvested as early as September, providing adequate time for establishing winter cover or cash crops.

2. Effective Establishment
Harvesting earlier allows for higher soil temperatures, which promote quicker germination and successful establishment of subsequent crops.

3. Reduced Soil Damage
Harvesting during drier conditions reduces the impacts of soil compaction and erosion, minimizing the necessity for extensive soil cultivation.

4. Enhanced Feed Quality
These varieties are more likely to be harvested at their nutritional peak, leading to superior quality feed for livestock.

5. Environmental Benefits
A well-established cover or cash crop curtails soil erosion and diminishes nutrient runoff into local waters, supporting both farming sustainability and environmental health.

Striking a Balanced Approach

While early-maturing maize varieties may yield slightly less than their later counterparts, the many benefits often overshadow this aspect. This approach offers farmers increased harvesting flexibility, improved feed quality, and significantly mitigated risks related to soil health and sustainability.
