What is blue manure?

Blue fertilizer is a chemical fertilizer

Blue fertilizer is a fast-acting, mineral artificial fertilizer from industrial production. In 1927, BASF launched the first synthetic complete fertilizer under the name Nitrophoska, which was primarily used in agriculture and horticulture. Since then, the composition and ingredients have been fine-tuned. The modern results are products with different recipes, tailored to the end user. Compo Blaukorn NovaTec is one of the most popular complete fertilizers for the hobby garden as NPK fertilizer 14 + 7 + 17 (+2) with this composition in detail:

• 14% nitrogen (N)
• 7% phosphorus (P)
• 17% potassium (K)
• 2% magnesium (MgO)
• as well as trace elements

Two criteria qualify this blue fertilizer as a suitable artificial fertilizer for the hobby garden: A special nitrifaction inhibitor slows down a too rapid conversion of nitrogen into nitrate and thus extends the duration of NovaTec's effectiveness to four to ten Weeks. Furthermore - compared to blue fertilizer for agriculture - the phosphate content is greatly reduced because the soil in most allotment gardens already contains plenty of phosphate.

Blue fertilizer benefits

Blue fertilizer disadvantages

Due to its disadvantages, blue fertilizer should only be used for specific reasons

• pollutes groundwater, seas (algae bloom), rivers (fish deaths), lakes (overturned inland waters)
• Species extinction as a result of creeping Nitrate inputs in the ground
• Risk of overdosing and over-fertilization
• must be rained in to avoid leaf burns

In view of these advantages and disadvantages, there are two main reasons for resorting to the mineral blue fertilizer: 1. Plants suffer from growth depression and marked deficiency symptoms that call for immediate growth help. 2. One Soil analysis shows significant nutrient deficiencies that cannot be remedied by natural, organic soil additives such as Compost soil.

An organic one Lawn fertilizer continues the blue grain instant effect with a natural long-term effect. As soon as the green area has completely absorbed the mineral fertilizer, clever hobby gardeners apply 50 to 60 grams per square meter of lawn Horn shavings(€ 32.93 at Amazon *) or an organic lawn fertilizer with an organic certificate. Blue fertilizer gradually runs out of breath after four weeks organic fertilizer caught up with the lead and stepped into the breach with natural nutrients. The result is a velvety green lawn cushion over a humus soil full of soil life.

When should you fertilize with blue fertilizer?

Blue fertilizer can be used from the beginning of spring to the end of summer

The time window for using blue manure is open during the growing season from March to September. At this stage, there is the best chance that most of the nutrients will actually be absorbed by the plants. Outside of the growing season, the ingredients of blue grain come to nothing, because neither soil organisms nor soil benefit from the artificial fertilizer.

Weather conditions also play an important role in deciding when to apply blue fertilizer. The sky should be cloudy and the weather should be rainy. Under these conditions, you avoid the risk that the plant leaves will suffer massive burns under solar radiation because the blue fertilizer grains remain on them.

Using blue fertilizer correctly - tips for hobby gardeners

Acute nutrient deficiency is the most common reason why concerned hobby gardeners prescribe blue fertilizer for their plants or the lawn as an immediate aid. In order for the advantages of the mineral artificial fertilizer to develop optimally and the disadvantages to remain within acceptable limits, important aspects must be taken into account when using it. How to use blue fertilizer knowledgeably bring the following tips to the point:
