In case of heavy rainfalls shortly after fertilization with nitrogen, will the nutrients be washed out from the soil?
In case of heavy rainfall, the terrain and the intensity of the rainfall are important. High quantities of water in a short period of time will lead to erosion of the upper soil layers in slopy areas. Thus a certain kind of nutrient loss can occur. On even, flat soil conditions there is no loss of nutrients even if rainfall occurs after fertilization.
How high are potential nitrogen losses to the air after applying a nitrate-based fertilizer?
Ammonia volatilisation is a direct loss of nitrogen, and therefore a significant environmental burden. The nitrogen losses to the air through ammonia volatilisation vary from fertilizers in line with their nitrogen form. It has long been known that urea or UAN causes higher volatilisation losses than ammonium nitrate or calcium ammonium nitrate. The official European Emission Inventory (EMEP 2013) assumes an average ammonia emission factor from urea of about 20% on arable land and grassland, compared to an average loss of around 2% for nitrate-based fertilizers. It is also a mechanism influenced by pedological, climatic and biological factors.
After the fertilization of NAC, the white granules are visible for a longer time on the surface of the soil. Does it mean that there is no effect?
The white granules are simply the lime-frames of the fertilizer, which are the carrier substance for the nutrients. Nitrogen is dissolved via humidity (morning dew is sufficient) from the fertilizer granule and is then available in the upper soil layer. When there is a longer dry period, the lime-frame is visible for a longer period of time.
Which nitrogen fertilizer is recommended for the late fertilization of grain?
For late fertilization, it is recommended to apply quick-acting nitrate nitrogen, such as NAC. Timing is important in this case. During earing, the wheat plant is developing from growth stage EC 39 (vexillum fully developed) to EC 55 (middle of earing) very fast. Urea application should be done early, in the vexillum (= flag leaf) period, as urea needs a few days for conversion. However, applying NAC instead is more effective on both yield and protein content due to the fast efficacy of nitrate. If only protein should be influenced, an application of NAC is recommended shortly before earing.
Which nitrogen-form is recommended for the first spring fertilization of grain?
For the start into vegetation, it is important to provide quick-acting, water soluble fertilizers. At this point in time, soil temperature is still low, therefore nitrate nitrogen is preferred. The effect of urea during this period is too late and uncontrolled.
How much time should be left between liming and a nitrogenous mineral fertilization?
Gaseous nitrogen losses appear after a fertilization at pH-values higher than 9. Calcium carbonates have a pH-value of 7,5 maximum, which makes fertilization right after liming possible without any gaseous nitrogen losses. If water soluble burned lime is applied, either a soil preparation between liming and fertilization has to be done or some precipitation needs to collect.
In which packaging forms can I get NAC?
We are offering NAC in bulk, in 600kg Big Bags as well as in 50kg bags.
Where can I purchase Borealis L.A.T fertilizer products?
Borealis L.A.T products can be obtained at our warehouses, from our trading partners and in different cooperatives. Please ask your local provider for Borealis L.A.T products.
Are the N-Pilot recommendations suitable for any N-fertilizer?
The N-Pilot is used during the shooting and flag leaf stage. It provides information about the current nitrogen need of the plants, giving an accurate N-recommendation. The fertilization should be applied immediately after the measurement, so only nitrate-containing and quick-acting nitrogen fertilizers are suitable to cover the needs of the plants at this time.
What are the main risk factors for nitrate leaching?
Nitrate leaching occurs when the soil is saturated with water and nitrate is washed beyond the root zone by percolating rainfall or irrigation. Nitrate leaching occurs regardless of the source of nitrogen. During the growing period, there is hardly any leaching. Most nitrate losses to water occur outside the vegetation period during winter. The overall objective is therefore to minimize soil nitrate concentration at the end of the cropping period. Leaching can be minimized by using Best Agricultural Practice.
Which fertilizers are ensuring the best NUE (nitrogen use efficiency)?
Nitrogen is essential for a good yield and plays a key role in the quality of the grain. The nitrate-based fertilizers such as those that Borealis L.A.T offers have a high NUE because the nitrate form is not volatile. All the nutrients are utilized for crop nutrition. Increasing fertilizers' efficiency enables limiting its dosage without reducing the quantity and quality of the crops. It also allows improvement to the energy performance of the cultivation and to limit the environmental impact of nitrogen.
