Fertilization for Irrigation

Lush green and splendidly flowering plants

In addition to watering, supplying the plants with the right amount of fertiliser is very important. Especially if an automatic irrigation system is already in place, we suggest adding liquid fertiliser to the irrigation system. This way, your plants will regularly receive all the important nutrients and microsalts without having to be fertilised manually during the season. For a good yield and a healthy development of your plants, we recommend fertilisation with a solid, organic slow-release fertiliser in spring at the beginning of the vegetation period.

Fertilisation and watering - an optimal supply of fertiliser to your plants

If you have a garden, then we recommend fertilising with liquid fertiliser to keep your plants healthy and strong. Organic fertiliser is particularly beneficial to the soil and micro-organisms. It ensures healthy growth of every plant via the release of plant nutrients. The organic materials in the fertiliser are gradually decomposed by bacteria and increase soil fertility. The nutrient content of the soil is being improved. Unlike mineral fertiliser, however, the nutrients are only released over time, so organic fertilisers release significantly fewer nitrates into the groundwater. Nevertheless, here, too, it is important to determine the fertiliser requirement and to dose it well, since, as with mineral fertilisers, there is a risk of it seeping into the groundwater. Fertilisation via your irrigation system is particularly efficient, as the amount of fertiliser required per irrigation cycle is very low and thus only low concentrations of nitrogen, phosphate and potassium are released.

Organic fertilisation - good for the garden, soil biota, plants and the environment

Organic fertilisers contain a variety of substances such as nitrogen, potassium, phosphate, lime, urea and ammonia. These nutrients are important for healthy plant growth. Organic fertilisers are often made from by-products of food and beverage production. These include, for example, extracts from sugar beet, cereals (corn, rye, wheat) and algae.  The quality and effectiveness of fertilisation is defined by the processing and selection of raw materials. The Fertiliser Ordinance/Fertiliser Law ensures that the plants receive the right amount of nutrients depending on the type of crop grown. They also help to reduce nutrient run-off from fields, which can impact groundwater quality if not adequately monitored.

The advantages of organic fertilisers over mineral fertilisers

Organic fertilisers offer further benefits compared to mineral fertilisers, such as improved soil texture, increased microbial activity and better control over nutrients release times. This helps to improve both crop yields and environmental protection. The use of fertiliser also needs to be monitored over time to maintain a material flow balance and ensure that the right amount of nutrients is being supplied to the crops. Excessive nitrogen fertilisation, ie. too high a concentration, can lead to leaf or root burn.

Nitrogen fertilisers for healthy plant growth

Fertilisers are an essential part of a healthy garden, providing it with the nutrients it needs to grow. Therefore, it is important to consider the effects of different types of fertilisers on plants, soils and water sources before deciding on the best fertiliser for your garden. With the right planning, organic fertilisers can help you achieve beautiful and healthy plants in your garden.

Automatic fertilisation: Feeding liquid fertiliser into the irrigation system

It is easy to add fertiliser to the water used for irrigation. The best way to do this is with proportional dosing. Regardless of the water quantities fed into the system, always the same percentage/ratio of fertiliser gets added. The fertiliser is then applied via the spray nozzles or drip pipes of the irrigation system. The subject of plant nutrition is becoming more and more important especially in increasingly dry summers. Well-managed fertilisation improves plant health and makes the plants and crops stronger to cope with periods of stress. This ensures yields in agriculture, in the cultivation of crops, but also in the home garden.
