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.
Is side-dressing fertilization better than top-dressing for maize?
This question cannot be answered with a simple yes or no. Fact is that on heavy, clay sub-soils, which are slowly heated in spring time, the side-dressing fertilization is more profitable. In warm areas or in years with very fast, early growth due to warm spring weather, as well as on soils with good phosphate content, there are mostly no differences in the yields. If top-dressing is applied, maize often reacts with a widely branched root-system compared to the plants with side-dressing. In years with very dry summer months, the crops with a better root system can take up more groundwater and thus gain higher yields.
Which quantities of phosphorus should be applied to maize?
Field trials in recent years have shown that a phosphorus fertilization in the same quantity as what was removed with the harvested quantities are most profitable. P-quantities given above that rarely result in higher yields. For maize with yields of 11 tons/ha (dry matter), a phosphorus application of 80 - 90 kg P2O5/ha is well-proven.
How much of the phosphorus in Borealis L.A.T NPKs are water soluble?
80% of the phosphorus content of the NPs and NPKs coming from our production in Linz is water-soluble; therefore, these products are quick-acting and effective. For accurate data, please have a look at the accompanying papers of our products.
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.
Which NP/NPK formula is best for supplementing cowshed manure?
Cowshed manure contains a small amount of phosphorus but has high potassium content; therefore, a P-emphasized NP fertilizer, such as 18/25 or 20/20, would be the best supplements.
Which NP/NPK formula is best supplementing pig manure?
Pig manure contains approximately 3,5 kg/m³ times as much phosphate as potassium. If 20 kg/m³ pig manure is given to maize before cultivation, an N-emphasized NPK fertilizer, such as COMPLEX 20/8/8 or VARIO 21/7/7, would be optimal supplements.
Which NP/NPK formula is best for supplementing poultry manure?
Poultry manure contains approximately 5 kg/m³ phospate and around 3 kg/m³ potassium, so it is a P-emphasized farm manure. P-weaker formulas, such as 14/10/20 or 24/10 (with a high potassium supply), are the optimal nutrient supplement.
