Pros and cons of treating strawberries with ammonia

Ammonia is composed of ammonia and nitrogen compounds. These elements are very necessary for any cultivated plants in the spring when they are actively building up their vegetative mass. The combination of ammonia and nitrogen will speed up the growth of the plants and therefore this product is considered one of the best spring dressings for strawberries.

It is important! Pure ammonia must not be used as fertiliser and must be diluted in certain proportions in order not to damage the strawberry crop.

Nitric acid is 4/5 nitrogen and is the ideal nitrogen fertiliser, and therefore most frequently used as a spring fertiliser for strawberries. And due to its special composition, ammonia quickly penetrates into plant tissues and is actively absorbed. Therefore strawberries grow faster but do not accumulate harmful nitrates.
