Effect of leaf fertilization on the quality of the brewery grain from selected common wheat varieties

DOI: 10.15584/pjsd.2021.25.1.1

The study assesses the effect of the applied foliar fertilization on the quality parameters
of selected wheat cultivars intended for brewing purposes. Foliar fertilization applied to
object A contributed to the highest yield increase of the tested objects for Elixir and
Rockefeller C1 wheat compared to the control object (0.64 and 0.49 t.ha-1, respectively) .
Gimantis wheat was characterized by the best technological parameters of the grain
regardless of the foliar fertilization applied (mainly total protein content and grain
uniformity), while the lowest yield and grain quality were obtained for wheat of the
Rockefeller C1 variety. Research into new cultivation technologies should aim for a higher
grain uniformity parameter for wheat intended for brewing purposes.

Assessment of straw use for energy purposes in selected farms

DOI: 10.15584/pjsd.2021.25.1.2

This article assesses the biological, technical, energy, environmental and economic
potential of straw on farms in Leżajsk Municipality, Podkarpackie Voivodeship, Poland.
The analysis included selected farms of non-livestock, crop-only, and crop and livestock
production types. The research shows that farms with a vegetable and animal production
(average 513.0 and 471.7 t.ha-1) had a higher biological and technical potential of straw
than non-livestock farms (average 344.4 and 321.6 t.ha-1). The energy potential of straw on
the farms examined was 47,598.0 GJ and varied between 1,618.5 and 11,979.0 GJ, and
was 31.8% higher on farms with both vegetable and animal production than on farms only.
Switching from traditional fuel (coal) to straw can reduce CO2 emissions on the farms
studied by 4,336.7 tons. For all farms (except farm No. 8) the investment in the purchase of
a biomass boiler, financed by the sale of surplus straw left after its use for energy purposes,
is profitable.

Social responsibility of charity associations in the light of empirical research

DOI: 10.15584/pjsd.2021.25.1.3

The article is devoted to the social responsibility of non-governmental organizations.
Activities undertaken by St. Brother Albert Aid Society operating in the district of Świdnik
have been assessed. The first part of the article presents issues related to the conc ept of
corporate social responsibility of business and non-governmental organizations.
The second part presents the results of research conducted among people using the
Society’s help and representatives of the local community who do not use such assistance.
The results of the survey confirmed the assumptions adopted in the study that with 36
the increase in the number of activities of the Society, the awareness of the problem of
poverty and homelessness grows, as well as the quality of life of people affected by these
problems. The conclusions from the research are presented at the end of the article.

The Bible’s environmental motivations

DOI: 10.15584/pjsd.2021.25.1.4

The preparation of the essay was preceded by a statement: nature is something
important to man, even sacred. There are also many arguments in the Bible. Bibliographic
material was completed, including the study of the Holy Scriptures of the Old and New
Testaments. After formulating the research problem, the motivations for activities related to
the protection of nature and biblical instructions were considered.

River renaturisation (restoration) as a chance to protect the sand martin Riparia riparia population in Poland

DOI: 10.15584/pjsd.2021.25.1.5

The regulation and reconstruction of rivers and their valleys, apart from drastic
hydrological changes, often lead to the change or disappearance of the habitats of valuable
plant and animal species. Particularly vulnerable to the loss of breeding sites are species
directly associated with precipitous banks and river slopes, which are formed as a result of
erosive and landslide processes. Intensive hydrotechnical treatments, such as straightening
56 of the channels or elimination of irregularities of the river banks, resulted in the inhibition
of the desirable natural river processes. Bird species native to Poland that require the
above nesting conditions, include: sand martin Riparia riparia, kingfisher Alcedo atthis
and bee-eater Merops apiaster. More and more actions are taken to restore rivers to a
near-natural state. The aim of restoration is not only to increase retention capacity, protect
against floods, social and economic benefits, but also to improve the overall functioning of
river ecosystems and preserve biodiversity within their valleys. Renaturation includes
activities such as the creation of exposed slopes that mimic erosive undercuts, the removal
of bank reinforcements or the maintenance of bank gaps, which promote their occ upation
by the aforementioned bird species. In addition to predation, the loss of suitable breeding
sites is the greatest threat to the sand martin population, such as the American mink
Neovison vison, the fox Vulpes vulpes and the locally raccoon dog Nyct ereutes
procyonoides. A regulated river, where the implemented hydrotechnical measures disrupt
the functioning of natural river processes, also causes losses in bird broods due to flash
floods that destroy many nests together with eggs or nestlings. Sand martins in many places
have stopped using riverbeds as breeding places, occupying anthropogenic habitats which,
however, have certain limitations and threats. Renaturation is therefore an important
measure to be taken in places where past regulations have caused the greatest damage to
the environment. The development of anthropogenic areas should be supported in
accordance with the principles of sustainable use of natural resources.

Industrial and energy use of maize plants

DOI: 10.15584/pjsd.2021.25.1.6

Maize (Zea mays L.) is a crop grown all over the world. Its availability makes it a
widely used species. It is a predominant food raw material for human or animal
consumption, used as a raw material for bioethanol production and in the chemical
industry. Another dynamically developing direction of the use of maize is their use for
energy purposes. The paper presents the possibilities of using maize plants in the industrial
aspect intended for energy production.

Implementation of the regional energy policy on the basis of planning

DOI: 10.15584/pjsd.2021.25.1.7

The document presents general directions of the energy policy of Poland and the EU,
principles of the regional energy policy based on the energy law and energy planning in the
municipality in the light of the objectives of the European Parliament. Energy planning
offers the possibility to forecast energy demand and coordinate the implementation of the
EP at different levels. At the municipal level, there are great opportunities to increase
energy efficiency, while reducing gas emissions and using renewable energy sources.

Selected elements of waste management in the Kańczuga commune

DOI: 10.15584/pjsd.2021.25.1.9

Waste management is an important part of the organization of life and sustainable
development. In 2013-2019, an analysis of data related to the state of waste management in
the municipality of Kańczuga was carried out. Using elements of the SWOT method,
a diagnosis was made of the waste management system in this municipality.
A questionnaire was also administered that assessed the selected behavior of the
inhabitants of the municipality and examined whether waste management in the
municipality of Kańczuga is in line with the environmental objectives of sustainable
development. The adoption of this topic has made it possible to draw conclusions about the
real needs of the municipality and corrective measures in the field of waste management
