Nowdays the world is batteling against environmental pollution within agricultural activities. When it comes to suppression of weeds and protecting the plants the biggest problems are pesticides. Their incorrect use can extensively harm environment, crop/stern and thus indirectly endangers humans and animals. One of the issues with pestecides are glyphosates, which negatively affect organism. Typical properties of weeds are rapid growth and consequently aggression toward crops, with which they have to fight for water, nutrients and light; there is also the possibility their aggression is so severe they destroy the crops. We know several methods of effective weed control: pestecides, mechanical hoeing, manual weeding, burning the weeds. We can also help ourselves by planting suitable crops or plants (fast growing to cover the ground; cover plants, etc.). In our experiment we preformed burning of the weeds on onions and carrots on inter-row distance of 75cm. We preformed weed burning three times on each crop, where the use of fire turned out as success only at lower speed, with high gas consumption, which is also a disadvantage of this method of weed control.
