Purchase criteria

Fertilizer form

Ammonium sulphate nitrate is available as a powder or as granules, the latter form having a number of advantages. The fine granules are dust-free or even dust-free, which is particularly important when applying - powder creates dust, can be inhaled and reach the respiratory organs. This causes irritation. In addition, granules are not blown away so quickly by the wind because the granules are larger and therefore heavier.

Grit

When buying, pay attention to the grit that comes with your Gritter should fit. Most ammonium sulphate nitrate fertilizers have a grain size between two and five millimeters and are therefore suitable for commercially available Gritter appropriate. If the granules are too big, they clog the spreader and cannot be spread.

coloring

Actually, ammonium sulphate nitrate is a colorless or white substance that is often sold that way. However, these nitrogen fertilizers are difficult to recognize, which is a disadvantage especially when fertilizing lawns - you cannot see where you have already fertilized and where not yet. You can effectively prevent this by choosing colored products - these can be yellowish or reddish-brown.

Packing

Ammonium sulphate nitrate is a rich fertilizer that you usually do not need much of.

Ornamental trees and shrubs receive between 40 and 60 grams, fruit trees between 30 and 40 grams and lawns 15 to 20 grams per square meter. That doesn't sound like much at first, but you have to do it every four weeks re-fertilize. For this reason, larger packages - around 25 kilograms - make sense, especially since ammonium sulphate nitrate can be stored for a long time. Do you only want pot or Fertilize potted plants, so smaller amounts are sufficient (e.g. B. a 5-kilo sack). Resealable containers have proven to be particularly practical.
