Lawn fertilizers: how to choose the right one


In early spring to get a healthy, lush lawn is important to choose the right fertilizer depending on grass type, exposure, if any "problems", such as yellowing or moss, and amplitude lawn. GardenTV has interviewed for this MAIN companies in the industry asking them to indicate their products among those most likely to this season and thus providing a broad overview of the products currently available.


For the spring period is particularly indicated for use by Biotron S, a completely natural product, made from organic matter and originating from plants of high quality raw materials, "explains Mariachiara Siciliani, product manager, division Home & Garden Cifo.

Biotron S initially favors engraftment and then the development of a healthy lawn, durable and intensely colored. "In fact - continues Mariachiara Sicilian - greatly improves the soil characteristics in terms of softness, porosity and fertility; It contributes, with a real detoxifying action, the natural degradation of polluting elements; It promotes the absorption of nutrients and promotes the development of new roots and shoots. "

Biotron S can be used on any terrain, and so for any type of grass (but also for ornamental and horticultural plants) and can be used from both private and professional. It is a slow-release product, then gradual release.

“It is a natural product consisting of Leonardite, substance extracted from the best natural sources of the European continent, and particularly rich in humic and fulvic acids that positively affect the health of the lawn and any plants ", explains the Sicilians. It is thanks to these valuable substances that Biotron S performs several important functions: it facilitates the absorption of nutrients such as phosphorus, iron, calcium, magnesium, etc); "Active" fertilizers, increasing the nutrient efficiency; It conducts bio-stimulating nature actions, promoting seed germination, and growth and activity of the absorbing roots; positively influences the physico-chemical characteristics of the soil, improving the buffer capacity of the soil; in soils contaminated by xenobiotics and / or potentially phytotoxic heavy metals, it acts as a "detoxifying" avoiding that they can be absorbed by plants.


Biotron S is administered mainly in spring - when performing tillage prior to transplantation and sowing or at the time of repotting - to help the vegetative growth and is also referred in the fall, to help the plant to overcome the stress of winter and prepare for vegetative growth. Biotron S should be mixed to the soil in a seeding phase of the lawn and with potting soil for repotting of plants, or be scattered directly into the pit transplantation of trees, bushes and shrubs. The dose for lawns is 50-100 g per square meter. The product is available in 5 kg bag.


There are two products that the office Compo marketing flag as most suitable at the beginning of the spring season: Compo fertilizer Rasen Floranid Spring / Compo Floranid Prato (the same product but with a different name depending on the package) and Compo Rasentec Spring fertilizer.

Both are suitable for vegetative growth and the rapid greening of the turf

" The product is ideal for residential ornamental grass-covered surfaces.


It has a 8.5.20 title. Nitrogen (N) is necessary for plants to grow. It is a source of energy essential for the formation of chlorophyll and photosynthesis. The phosphorus (P) is essential for the plant's tissues, for the rooting and tillering while potassium (K) balance the water content and increases the resistance to stress factors ", illustrates Grisotto.

This fertilizer is a CRF (Controlled Release Fertilizers) or controlled release fertilizer in here 40% of the nitrogen is wrapped and is transferred over a period of 3 months.

"ICL - he explains - has different technologies to handle the sale of the elements for plant nutrition. In LandscaperProMantenance we use the technology polys: Urea wrapped by a sulfur layer and a menbrana.

Neudorff Azet PratoCOMPOSITION

The fertilizer for lawns Azet - continues Riva - is a totally organic fertilizer; it is composed of only natural substances allowed in organic farming: dried vinasse extracted without the use of ammonium salts; bone meal; panels. The organic nitrogen content of the fertilizer contributes to the development of plant tissues and is essential for photosynthesis. A deficiency would lead to a lawn with a stunted development, with fabrics that tend to yellow and not very resistant to heat and frost.

Phosphorus is essential for all physiological processes of plants, including grass. It has a key role in root development and, consequently, the efficiency of absorption of nutrients.

Potassium plays a key role in regulating the water balance of plants; a good supply of potassium allows the plants to better resist to adverse weather conditions such as frost and drought.

The good content of organic carbon and humic acids also contributes to the fertility of the soil fertilized with manure Azet for "meadows.

Feature exclusive fertilizer for lawns Azet is its content in mycorrhizal fungi (MyccoVital) that give rise to mutualistic "binding" associations root system of the lawn. In the wild, more than 90% of the plants live in symbiosis with these fungi obtaining numerous advantages; thanks to mycorrhiza, you will get a greater root development of the lawn so that it will be able to absorb more nutrients. More absorbed nutrients translate into a more lush meadow, more resistant to frost and drought, absence of moss. The nutrients supplied by the fertilizer are readily available and, thanks to its granular formulation, they are for a long period (3 months).

"The fertilizer for lawns Azet - says Lorenzo Riva - is suitable for all uses, from the lawn of a private house on the lawn of a sports field. In addition, due to its lack of any risk to people and animals, it can also be used in areas frequented by people (just as gardens or parks) without risk ".


The ideal use period - answers Riva - from March to June, at the vegetative growth of grass and its development. In March, it is recommended to use especially in case of situation of "patchy lawns"; April to June is ideal to support the growing recovery of the lawn to provide all the necessary nutrients, thus preventing yellowing and stunted development. "

The fertilizer for lawns Azet can be distributed by hand or by means of appropriate fertilizer. Doses vary depending on the situation: in the case of existing fields is recommended to distribute 50 g / m2 in early March and 50 g / m2 in May. For new lawns is recommended to distribute 100 g / m2 just before or simultaneously with the planting and to distribute 50 g / m2 weeks after 8/10.

Remember that it is important to water the lawn just after fertilization. The fertilizer for lawns Azet is available in 2.5 kg bags in the box and from 6 and 10 kg
