Fertilization and sowing from unmanned aerial vehicles

Berner Bogusława

Polish Technical Review

2020

No. 2

18--22

In the paper, the modern technologies, utilizing unmanned aerial vehicles, drones, in sowing the seeds and distribution of fertilizers on the fields, have been described. Their construction, the examples of the application and the operating parameters have been presented. In the article, there have been also given the examples of the laboratory tests of the effect of the air stream, produced by rotor of drone - multicopter on the surface distribution of the sown seeds.

W artykule opisano nowoczesne technologie wykorzystujące bezzałogowe statki powietrzne, drony - do siewu nasion i rozsiewania nawozów na polach. Opisano ich budowę, przykłady zastosowania, podano parametry operacyjne. W pracy przedstawiono również wyniki badań laboratoryjnych nad wpływem strumienia powietrza wytwarzanego przez wirniki drona - multikoptera na rozłożenie na powierzchni rozsiewanych nasion.

Effect of binder additive on mechanical properties of straw pellet

Zdanowicz Agnieszka, Ondruška Juraj, Chojnacki Jerzy, Križan Peter, Berner Bogusława, Matúš Miloš

Journal of Mechanical and Energy Engineering

Research was carried out into the impact of the content of wheat flour in a mixture with chopped wheat straw and the humidity of this material on the hardness of the pellet obtained from this raw material. The maximum content of wheat flour was 9.6% of the dry matter of the raw material, and the humidity of the raw material was 11.6, 25.7 and 36.0%. An increase of wheat flour content in the whole range examined considerably increased the pellet hardness, while an increase of humidity content in the raw material had an impact on increased hardness up to 25.7% only.
