The aim of the paper is to identify changes in nitrogen management in individual agriculture and result assessment in the context of sustainable development. The paper showed the essential elements of nitrogen balancing on agricultural area. Research was conducted at a national as well as voivodship level, making it possible to determine the scale of diversity of regional nitrogen management in individual...
The study discusses the results of the analysis of changes in the management of natural fertilizers in Poland and voivodships. Analysis included changes in: the number and percentage of individual farms using natural fertilizer, fertilized area, and level of consumption of particular fertilizer types. The comparative analysis at a voivodship level concerned the years 2007 and 2016. The current situation...
The study compares the trends of changes in the intensity of management (direct costs incurred) in relation to changes in the value of production in groups of farms with different production profiles. The basis for comparative analysis were the results of surveys conducted in 2004-2017, in several dozen large, market-oriented farms. The specific structure of gross commodity production was the main...
Subject and purpose of work: Agricultural production activity brings about specific environmental effects. The aim of the study was to analyse changes in agricultural production in regions of Poland (NUTS-2) in the context of environmental impact using the gross nitrogen balance. Materials and methods: The analysis covered the medium-term perspective of 2001-2016. The primary source of information...
W pracy przedstawiono zagadnienie gospodarki nawozowej azotem, uwzględniając zróżnicowanie regionalne, w perspektywie średniookresowej obejmującej lata 2004–2015 (2017). Podstawę analizy porównawczej na poziomie województw (NUTS-2) stanowiły dane statystyki masowej. Z przeprowadzonych analiz wynika, że prowadzenie odpowiedzialnej gospodarki nawozowej (pod względem efektywności produkcyjnej i potencjalnych...
The aim of the research was to assess the soil pH, the content of phosphorus, potassium, magnesium and organic matter in the soil in a group of 30 organic farms of different production profile located in the Lubelskie, Podlaskie and Mazowieckie Voivodeships. The research was carried out in the years 2011-2012. The analyzed farms were divided into three groups: specialized in crop/horticultural production,...
W opracowaniu dokonano oceny wykorzystania azotu w polskim rolnictwie w układzie przestrzennym (NUTS-0 i NUTS-2). Przeprowadzona na podstawie bilansu azotu brutto analiza wskazuje na poprawę wykorzystania tego makroskładnika w procesie produkcji rolniczej w Polsce w latach 2002- 2014. W ostatnich latach efektywność wykorzystania azotu znacznie przekroczyła poziom 60%, pomimo utrzymujących się nadal...
Phosphorus (P) is an essential building block of life. It is an irreplaceable part of agriculture, as there is no substitute for its use for producing food and feed. The objective of P fertilization is to add an adequate (in regard to soil test P) amount of P to produce an economical yield. Unbalanced P management leads to P wastage, lower cost-effectiveness of production, and water quality impairment...
