What is the consumption of lawn grass seeds per 1 m2?

Many owners of suburban areas and private houses are interested in the consumption of lawn grass seeds per 1 m2. Creating a beautiful green area is solved by sowing one or several plant species. However, before buying seeds, you need to accurately calculate their number. This problem does not apply to those who chose roll materials with a finished green glade.

Sowing rates

Start the preparation with the measurement of the lawn area. Taking as a basis the consumption of lawn grass seeds per 1 m2, the required amount of planting material is calculated. In some sources this value is indicated in different dimensional units: from a square meter to a hectare.

The importance and principle of the matter is also in the fact that the standards are indicated not only by the mass of the seed material, but also by their number. To ensure the necessary density of the grass stand, the seeding rates must be observed.

Other factors, such as the quality and mass of the material, the amicability of the shoots, the tillering capacity, the area of nutrition and the soil, as well as the conditions for the care of germinating plants (irrigation, fertilization, etc.) affect the consumption of seeds of lawn grass per m2.

Changing norms

What was the consumption of lawn grass seeds per m2? GOST did not provide for this. In the old days, classic green carpets were created according to the seeding rates, ranging from 6.25 to 7.5 kg per hundred square meters. Gradually accumulated scientific works and practical data, the soil was better prepared. All this led to a significant reduction in seeding rates, which have survived to this day.

It is worth considering that for different plant species figures will vary. This circumstance does not allow us to specify the specific value of the norm for lawn grasses.

Factors affecting the standard

Plants are in continuous interaction, intra- and interspecific competition is observed . Nearby are representatives of the flora of one crop and weed populations. The latter sprout from seeds that are in the form of an impurity in the package or in the soil under a future lawn.

What other factors are taken into account when calculating the consumption of lawn grass seeds per square meter? The percentage of germination is taken into account, and also part of the sprouts that die in the first weeks of life. When creating a lawn, the main goal remains unchanged: obtaining a mass of green shoots that will create a dense and beautiful grass stand.

The presented calculations are valid for an ideal planting stock, which has 100% economic suitability. In practice, an amendment should be made, depending on the germination indicated on the packaging of the seeds to be purchased. For a quality lawn, only those that have a score of 75% will do. Seeds of more than 4 years old are discarded, which have an unpleasant odor or traces of spoilage.

Planting a lawn

Before purchasing the planting material, you should determine the purpose of the green lawn. It can serve as a base for sports and children's playgrounds, a decorative element of the landscape or to keep slopes from falling apart. Each of the listed objects requires the selection of a special grass mixture. They differ in species composition and ratio of components.

What is the consumption of lawn grass seed for 1 m2 as a basis? In most cases, this value ranges from 30 to 50 g. Light soils are based on a parameter of 30 g, and on heavy soils - from 40 g.

When planting, it is important not to overdo it, because the seeds will feel a shortage of food, which will lead to rare seedlings. With a low landing rate, there will be areas without grass, which will spoil the decorative effect.
