Abstract

Water scarcity is a phenomenon that is occurring more and more frequently in larger areas of Europe. As a result of drought, there are significant drops in yields. As demand for food continues to rise, it is becoming necessary to bring about a substantial increase in crop production. The best solution to water scarcity appears to be irrigation for crops that are particularly sensitive to drought. Today, many technical solutions are used to supply and distribute water to crops. The optimal solution is drip irrigation, which makes it possible to deliver water directly to the plant root system to save melting freshwater resources. In the article special attention was paid to methods of supplying electricity to power irrigation pumps. The analysis was made for areas with a significant distance between the agricultural land and the urbanised area (which has water and electricity). The authors have selected the parameters of an off-grid photovoltaic mini-hydropower plant with energy storage (with a power of 1.36 kW). An analysis was made of the profitability of such an investment and a comparison with other types of power supply. Based on the performed calculations, a prototype power supply system equipped with photovoltaic panels was made to show the real performance of the proposed system. The tests carried out showed that the irrigation pump will be powered most of the time with a voltage whose parameters will be very close to the nominal ones.

Abstract

The article presents results of monitoring carried out in barns with milking robots. The use of milking robots makes it possible, with proper stocking, to milk cows without human intervention. The analysis included all barns with Lely robots located in the Podlaskie Voivodeship in 2018–2021. In 2018–2019, there were seven such barns, and in 2020–2021 nine. In all barns, high milk yields were obtained of more than 1000 kg compared to the average milk yield obtained from stock of cows under monitoring in the Podlaskie Voivodeship. In 2021, four barns milked more than 9.5 thous. kg, three barns more than 10 thous. kg and two barns almost 12 thous. kg of milk. Fat and protein contents were typical for the breed. Three barns were monitored more closely in 2021, with varying numbers of robot milking stations in barns, i.e. A one, B two and C three milking stations. In 2021, over 700,000 kg was milked per stall in stall A, over 750,000 kg in B and over 850,000 kg of milk in C. The average milk per cow per milking was high, with over 11 kg in barn A, 12 kg in B and 13 kg in C.

Abstract

Agricultural biogas plants are not only a place for processing waste resulting from animal husbandry, but also for generating electricity and heat as well as organic fertiliser. In a four-year experiment, pellets were used as organic fertiliser in the establishment of an experiment with fast-growing oxytrees. The study aimed to investigate the growth and stem thickness increment, overwintering in the first and subsequent years of cultivation under the conditions of north-eastern Poland.
The dried digestate and the pellets made from it were characterised by a high content of macroelements (N – 1,95%, P2O5 – 1,1%, K2O – 1,3%). The applied pellet from an agricultural biogas plant under oxytree seedlings due to its slow decomposition had a good effect on the growth of oxytrees in the second and third years. The average growth of oxytrees in the second year was 209.7 cm, and in the third year, 246.8 cm. The growth of oxytrees fertilised with pellets made from the digestate of an agricultural biogas plant was 13% higher than that of trees growing on the control strip.
