DAP 18/46

This highly concentrated (N)P-fertilizers is estimated by large firms from working for economic reasons.
Application hint: As part of crop rotation, nitrogen fertilizer, phosphate and potash can be separate and can applied in times of low employment (or after harvest in autumn). Work peaks in spring can be avoided.

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.
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 sulphur is recommended for rapeseed?
A crop stand with a yield of 4 tons/ha takes up 32 kg S/ha via the corn, compared to the take-up of the entire plant of 56 kg S/ha. As sulphur is hardly provided anymore from the atmosphere and the mineralisation of sulphur takes place very late (around soil temperatures of 12 C°), a sulphur fertilization to the extent of 30 to 40 kg S/ha is recommended. Sulphur can be given with S-containing NPK fertilizers and N+S fertilizers, both in autumn and spring.
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.
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.
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.
