Item Assessment of soil impact on pre- and post-harvest NDVI extrema by machine learning(Polskie Towarzystwo Gleboznawcze, 2024-06-01) Łopatka, Artur; Koza, Piotr; Suszek-Łopatka, Beata; Siebielec, Grzegorz; Jadczyszyn, JanIt was observed that the difference in the maximum and minimum NDVI values at a time close toharvest (mxNDVI and mnNDVI, respectively), referred to as the haNDVI index (harvest amplitudeof NDVI), correlates with agricultural soil quality and the share of sowings. The NDVI becomes satu-rated when the values of the Leaf Area Index (LAI) signi ficantly exceed one so spatial variation inhaNDVI is mainly due to the minimum post-harvest NDVI (mnNDVI). To explain the variability ofmnNDVI values three hypotheses were formulated: i) impact of crop selection, ii) field size impact,and iii) impact of soil. To determine which of these hypotheses had the highest impact on the vari-ation in the mnNDVI, the developed machine learning models of this indicator were subjected toa test removing individual explanatory variables from them. Removing a variable does not causea signi ficant increase in model error if a variable does not contribute useful information to themodel. This test showed that the mnNDVI index depends almost exclusively on the crop indicatorwhich was the median of mnNDVI for crops, not directly from soil variables such as the agriculturalquality of soil or soil moisture. According to this, the hypothesis of direct impact of soil was rejected.The explanation for the observed correlation of haNDVI with soil quality is the agricultural practiceof choosing crops with low mnNDVI (cereals, rapeseed) at better soil conditions and crops with highmnNDVI (fodder crops, grassland) for worse soil conditions.Item Crop production intensity and haNDVI indicator – amplitude of NDVI related to harvest(Instytut Uprawy Nawożenia i Gleboznawstwa – Państwowy Instytut Badawczy w Puławach, 2020) Łopatka, Artur; Koza, PiotrItem Development of Agriculture in Mountain Areas in Europe: Organisational and Economic Versus Environmental Aspects(MDPI, Basel, Switzerland, 2026-01-03) Zieliński, Marek ; Łopatka, Artur ; Koza, Piotr ; Sobierajewska, Jolanta ; Juszczyk, Sławomir ; Józwiak, WojciechThe article analyses the direction and intensity of changes occurring in agriculture in mountain areas in Europe between 2000 and 2022. For the calculations, the ESA CCI Land Cover global land-use map set was used. This dataset was established by the European Space Agency (ESA) through the classification of satellite images from sources (MERIS, AVHRR, SPOT, PROBA, and Sentinel-3). In the next step, the organisational features and economic performance of farms located in mountain areas of the European Union were determined for the period 2004–2022. For this purpose, data from the European Farms Accountancy Data Network (FADN-FSDN) were used. Subsequently, using Poland as a case study, the capacity of mountain agriculture to implement key environmental interventions under the Common Agricultural Policy (CAP) 2023–2027 was assessed. The results highlight the varying directions and intensity of organisational changes occurring in mountain agriculture across Europe. They also show that farms can operate successfully in these areas, although their economic situation varies between EU countries. The findings indicate the need for further adaptation of CAP instruments to better reflect the ecological and economic conditions of mountain areas. Strengthening support mechanisms for these regions within the current and future CAP is of crucial importance for protecting biodiversity, promoting sustainable land use, and maintaining the socio-environmental functions of rural mountain landscapes. Our study highlights that the CAP for mountain farms should be targeted, long-term, and compensatory, so as to compensate for the naturally unfavorable farming conditions and support their multifunctional role. The most important assumptions of CAP for mountain farms are a fair system of compensatory payments (LFA/ANCs), support for local and high-quality production, income diversification, and investments adapted to mountain conditions.Item Egzogenna materia organiczna jako element Europejskiego Zielonego Ładu(Instytut Uprawy Nawożenia i Gleboznawstwa Państwowy Instytut Badawczy, 2021) Siebielec, Grzegorz; Siebielec, Sylwia; Kaczyński, Radosław; Gmur, Dominika; Koza, PiotrItem Metodyka interpolacji opracowana na potrzeby tworzenia map zagrożeń gleb(Instytut Uprawy Nawożenia i Gleboznawstwa Państwowy Instytut Badawczy, 2018) Łopatka, Artur; Koza, Piotr; Stuczyński, TomaszItem Naturalne czynniki ograniczające użytkowanie gleb w Polsce i w Unii Europejskie(Instytut Uprawy Nawożenia i Gleboznawstwa Państwowy Instytut Badawczy, 2013) Łopatka, Artur; Koza, PiotrItem Obszary Problemowe Rolnictwa (OPR) oraz ONW w Polsce różnice kryteriów i zasięgów przestrzennych(Instytut Uprawy Nawożenia i Gleboznawstwa Państwowy Instytut Badawczy, 2010) Jadczyszyn, Jan; Filipiak, Krystyna; Stuczyński, Tomasz; Koza, Piotr; Wilkos, StanisławItem Ocena przekształcania i zasklepiania gleb użytków rolnych na cele urbanizacji(Instytut Uprawy Nawożenia i Gleboznawstwa Państwowy Instytut Badawczy, 2018) Jadczyszyn, Jan; Siebielec, Grzegorz; Łopatka, Artur; Koza, PiotrItem Ocena ryzyka zagrożenia erozją wodną w Polsce na podstawie modelu USLE(Instytut Uprawy Nawożenia i Gleboznawstwa Państwowy Instytut Badawczy, 2011) Łopatka, Artur; Koza, Piotr; Jadczyszyn, Jan; Stuczyński, TomaszItem Potential of agroforestry systems in preserving Europe’s soil productivity in lowland and highland landscapes by limiting soil erosion by surface runoff(Instytut Uprawy Nawożenia i Gleboznawstwa – Państwowy Instytut Badawczy w Puławach, 2021) Wawer, Rafał; Koza, Piotr; Borek, Robert; Gliga, Adrian-Eugen; Bahadur Ghaley, Bhim; Xu, Ying; Smith, Jo; Smith, Laurence; ?andor, Mignon; Pisanelli, Andrea; Augusti, Angela; Russo, Giuseppe; Lauteri, Marco; Ciolfi , Marco; Lehmann, Lisa M?lgaard; Nowocień, Eugeniusz; Badora, DamianItem Prognoza wpływu EZŁ na właściwości gleby i plony zbóż z wykorzystaniem metod uczenia maszynowego(Instytut Uprawy Nawożenia i Gleboznawstwa Państwowy Instytut Badawczy, 2021) Łopatka, Artur; Smreczak, Bożena; Łysiak, Magdalena; Koza, Piotr; Suszek – Łopatka, BeataItem Program rolnośrodowiskowy i zalesienia na obszarach problemowych rolnictwa zagrożonych erozją wodną(Instytut Uprawy Nawożenia i Gleboznawstwa Państwowy Instytut Badawczy, 2011) Jadczyszyn, Jan; Koza, PiotrItem The Carpathian Agriculture in Poland in Relation to Other EU Countries, Ukraine and the Environmental Goals of the EU CAP 2023–2027(MDPI, 2024-08) Zieliński, Marek; Łopatka, Artur; Koza, Piotr; Gołębiewska, BarbaraThis study discusses the issue of determining the direction and strength of changes taking place in the structure of agricultural land in the mountain and foothill areas of the Carpathians in Poland in comparison with Slovakia, Romania and Ukraine. The most important financial institutional measures dedicated to the protection of the natural environment in Polish agriculture in the Areas facing Natural and other specific Constraints (ANCs) mountain and foothill in the first year of the CAP 2023–2027 were also established. Satellite data from 2001 to 2022 were used. The analyses used the land use classification MCD12Q1 provided by NASA and were made on the basis of satellite imagery collections from the MODIS sensor placed on two satellites: TERRA and AQUA. In EU countries, a decreasing trend in agricultural areas has been observed in areas below 350 m above sea level. In areas above 350 m, this trend weakened or even turned into an upward trend. Only in Ukraine was a different trend observed. It was found that in Poland, the degree of involvement of farmers from mountain and foothill areas in implementing financial institutional measures dedicated to protecting the natural environment during the study period was not satisfactory.Item Uwarunkowania produkcji rolniczej w regionach o dużym udziale gleb zanieczyszczonych metalami śladowymi(Instytut Uprawy Nawożenia i Gleboznawstwa Państwowy Instytut Badawczy, 2008) Siebielec, Grzegorz; Stuczyński, Tomasz; Terelak, Henryk; Filipiak, Krystyna; Koza, Piotr; Korzeniowska-Pucułek, Renata; Łopatka, Artur; Jadczyszyn, JanItem Wdrażanie wybranych pakietów rolno-środowiskowych oraz zalesień na obszarach problemowych rolnictwa (OPR)(Instytut Uprawy Nawożenia i Gleboznawstwa Państwowy Instytut Badawczy, 2015) Jadczyszyn, Jan; Koza, PiotrItem Występowanie suszy rolniczej w Polsce w latach 2006–2022(Instytut Uprawy Nawożenia i Gleboznawstwa Państwowy Instytut Badawczy, 2023) Doroszewski, Andrzej; Koza, Piotr
