Improving Nitrogen fertiliser Use Efficiency (NfUE) will be one of the most important ways in which UK growers can improve their business productivity in the future.
The single most important decision you can make to maximise your NfUE lies in the type of fertiliser you choose in the first place, says CF Fertilisers’ head agronomy Dr. Sajjad Awan. Whilst good management can help finetune the effectiveness of your applications, start with the wrong Nitrogen source and you’ll be locked into lower levels of NfUE with little you can do to lift it, he says.
“NfUE is essentially a measure of how much of the Nitrogen applied ends up in the crop. “In simple terms, if you apply 100kg N/ha and only 50kg N/ha is taken up by your crop, you will have an NfUE of 50% and half of the N you have paid for has gone somewhere other than into your crops as intended “Improving NfUE benefits your crop, your pocket and the wider environment.
Whether you are looking at it from the perspective of clean air, reducing your carbon footprint or increasing production efficiency, loss of N from the cropping system is a major problem.”
Dry matter – Is grass providing enough dry matter intake to support the energy requirement for milk production and getting cows back in calf?
Protein – Grass is high in rapidly degradable protein; this needs to be utilised by the rumen microbes in order for them to produce microbial protein. Poorly utilised protein can have a negative impact on fertility and limit milk yield.
Rapidly fermentable carbohydrates – Early season grass is high in sugar (and digestible fibre), this can be an issue for rumen health. A consequence of this can be milk fat depression and a reduction in milk value. It is important to understand the nutrient content of grass. Fresh grass analysis throughout the grazing period will provide useful information about the points above.
Overseeding is a simple but effective way to rejuvenate old or damaged grass leys, without the cost implications associated with a complete reseed. Overseeding can also be more efficient and reduces the amount of time that home-grown grass forage is out of production.
Timing is imperative with overseeding, and the main aim is to minimise competition from the existing sward. The best time to overseed is March, April, July or September as the grasses are not growing as vigorously as they are in May and June.
Clearfield® is a unique system for oilseed rape that combines hybrid seed varieties and high-quality BASF herbicides for the most effective way to approach weed control in OSR.
It is difficult to manage the nitrogen use of oilseed rape as it is dependent on the conditions of the soil. After many years of research and development, the team at Limagrain have developed a number of varieties. These newly developed varieties harness Nitrogen during the key stages of growth. They also reduce the risk of yield losses in less desirable conditions.
One common cause of high seed loses in commercial oil seed rape crops is pod shatter. In this short blog we look at what pod shatter is, what causes it, and how our supplier LG seeds is working to develop resistance in its varieties.
Grass and silage remain the best value feeds available to UK livestock farmers, despite the increasing fertiliser prices. Producing high-quality, homegrown forage is cost-effective and plays a crucial role in herd and flock performance; but planning is essential to get these results.
Inclusion of spring cereal crops in a rotation can be economically beneficial, providing either cash crops or valuable home-grown starch and energy feed sources. However, to see a good return on investment, it’s important to achieve maximum potential yields and this requires attention to detail when it comes to a nutrient plan.
Dairy farmer Jonathan Evans wanted to improve milk quality from his 220 cows to improve milk price and he is now reaping the benefits of close teamwork between his Wynnstay Agronomist and Nutritionist.
