Low grass silage stocks have been a significant subject of conversation this summer, stemming from the adverse impact of a dry June on grass growth.
Although we had rain towards the end of June, it was patchy. Where rain did fall, it often came in short, heavy bursts. If the ground was baked hard, this made it prone to run off. What we needed was prolonged rainfall to wet the ground so it could soak in.
Maize management
In addition to disappointing grass growth in some areas, we’ve seen huge variability in forage maize growth this year. Whilst a small number of crops have already reached head height, others are not yet up to your knees.
In difficult seasons like this, attention to detail when managing maize is crucial. Any problems that haven't been fully addressed become evident as the crop develops. In easy seasons, there is more leeway.
If concerned about grass yields and filling the silage pit, concentrate on getting every last ounce out of maize crops. Consider foliar nutrition, biostimulants, and choice of silage additive.
Some 30% of maize’s nitrogen requirement is between tasselling and maturity, when cobs are filling. Using tall sprayers and the right speed allows for applying nutrients and fungicides before tasseling to increase crop yields.
Maize additive
Similarly, do not neglect preserving maize with a quality additive. If you don’t have enough grass silage, it becomes crucial to reduce losses in dry matter and preserve the nutritional value of maize silage.
Ecocool dual-acting additive
Ecocool by Volac contains beneficial bacteria that address two issues in maize silage. These problems are bad fermentation and heat generated by yeasts and molds. Ecocool has been shown to keep maize cool for 10 days.
