If, despite careful maintenance, nothing grows properly in your garden, it may be due to the quality of the soil. Now a nutrient analysis is appropriate!
Even with a lot of experience, it is not always easy for a hobby gardener to correctly estimate the realistic nutrient supply in the soil. Despite good lighting conditions and actually a good type of soil, plants take care of themselves or even get diseases. Not only a lack of nutrients is considered here as a reason.
Nutrients can also harm your plants
The most important nutrients your plants need for development and growth are phosphorus, magnesium, potassium and nitrogen. You can feed these to your plants by applying fertilizers.
Tip: So that your plants can absorb the nutrients, the soil must have a certain pH value. In most cases, this is between 7 and 8.
But be careful not to give your plants too much fertilizer. This will damage your plant more than you might think. Phosphorus and potassium accumulate in the soil - more with each fertilizer application. If the critical amount of phosphorus and potassium in the soil is exceeded, plant growth is inhibited.
And an excess supply of nitrogen also has a negative impact on the development of the plants. Because this causes the plant to produce too many amino acids and proteins and no longer has enough strength to form strengthening tissue. The consequences can be growth that is too fast, leaves and sprouts that are too soft and unstable, or that the plant is too fast.
Soil analysis creates clarity
Soil analysis is useful to find out why your plants don't want to thrive. The agricultural investigation and research institutes, called LUFA for short, carry out the analyzes.
After the analysis, you will receive an evaluation with reliable information on the soil type, the nutrient content and the pH value. Based on this, you will also receive specific fertilizer recommendations and possibly also a recommendation for treating the soil with lime. This is necessary if the soil is too acidic.
If you would like to have a soil analysis carried out, you can contact VDLUFA in Darmstadt. There you will find all the important information on the process and the cost of a nutrient analysis. Soil analysis always makes sense between autumn and the following spring.
Take soil sample
If you want to have your soil analyzed, it is necessary to take several soil samples in the area concerned. It applies that
You should take 20 samples per 100 m². Make sure that you always take the sample from the entire root zone. You would have to go about ten centimeters deep for a lawn, about 30 centimeters in the vegetable or perennial border and about 60 centimeters for fruit trees.
When you have taken all the samples, mix them thoroughly and remove any plant residues. About 500 grams are sufficient for soil analysis
Tip: Since nitrogen is very mobile, the concentration in the soil fluctuates enormously. If you want to have the nitrogen content in the soil analyzed, you must freeze the sample immediately and send it to the soil laboratory in this state.
