We restore the lawn after the winter with the help of ammonium nitrate

Good day! My lawn is a problem. When the snow melted, it turned out that almost the entire lawn was dead - the grass is limp, faded and it seems that it will not live again. I read on the Internet that applying nitrogen fertilizers can have a beneficial effect. Is it so? And if so, explain how to fertilize the lawn with ammonium nitrate after winter?

First of all, in such a situation, you can advise not to rush. During the six months of being under the snow the grass dies - this is quite normal. Of course, in countries of Europe, the USA and Canada, where the climate is much softer, the lawn can please the owners with fresh greens for a whole year. But if the snow has lain for half a year, and the ground has frozen to half a meter, you shouldn’t hope that the spring lawn will be beautiful.

As practice shows, under a layer of snow, depending on the length of winter and the lowest temperatures, 45 to 90% of grass is killed. But this does not mean that the root system perishes. Therefore, it is worth waiting until the snow finally disappears, the earth dries out a little and warms up. Almost certainly, most of the roots will come to life and will give new shoots. By mid-May - mid-June( depending on the weather and region), the lawn will almost completely recover. The grass that died during the winter should be removed - it is best to use a fan-like rake or broom for this. But first, wait until the lawn is slightly dried by melt water. Otherwise, footprints will remain on its surface.

Of course, you should not forget about feeding. Knowing how to fertilize a lawn with ammonium nitrate after the winter, you can help the lawn to get into better shape faster.

We fertilize the lawn correctly

If you are looking for suitable fertilizer for the lawn, then nitrogen mixes will be an excellent choice from late spring to mid-summer. After all, it is nitrogen that the lawn needs in the first place, in order to restore the green mass faster and to maintain a great appearance even with regular cutting.

Ammonium nitrate can be one of the main suppliers of nitrogen. The nitrogen content in it reaches 35%.Therefore, after 7-10 days after making the mixture in the soil, you will not recognize your lawn.

The first dressing can be done at the end of April, when the earth is fully warmed up and dries out, and the grass gives the first shoots. The most important thing here, as when using any chemical fertilizers, is to properly observe the dosage. Yes, nitrogen fertilizers are good for lawn. But do not act on the principle of "porridge butter will not spoil."Excess nitrogen may well burn out the lawn, giving you a lot of trouble to restore it.

The optimal amount of ammonium nitrate is about 30-40 grams per square meter. More specifically, you can learn from the instructions on the label. It is advisable to equip with accurate weights, so as not to be mistaken with the proportion. It is possible to distribute the fertilizer manually, but it is extremely careful to do this, and after the procedure is over, wash your hands thoroughly.

Immediately after spreading fertilizer, it is advisable to water the lawn well so that the soil gets wet and quickly absorbs saltpeter.


Repeat the procedure preferably every month until mid-late August. During this period, preference should be given to phosphate fertilizers in order to strengthen the root system, ensuring that the lawn grass will easily survive the winter and will not need to sow the seeds in spring.

However, saltpetre should also be used carefully - the acidity of the soil rises slightly after it is applied. On neutral and alkaline soils it is not dangerous, but on those with increased acidity it can cause plant disease.
