Weed Control Maize can suffer considerably from weed competition during the early growth stages. Ideally, a clean, weed-free site should be chosen. A weed control programme applying either pre-emergence and/or post emergence herbicides can be followed. Environmental Considerations Harvesting maize in wet conditions can lead to surface compaction. Maize stubble left uncultivated over the winter months can result in surface water runoff and nitrate leaching into waterways. There is also a particularly high risk of soil erosion where fields are sloping and have sandy soil. If your fields are of a higher risk then consider growing an early maturing variety aiming for an early harvest in better weather, a light cultivation after harvest will encourage rainfall ingression and reduce run off or establishing a cover crop to stabilise the soil surface may be a good option.
