Evidence from Polish FADN During the 2020–2022 Multi-Crisis Period(MDPI, 2026) Madej, Andrzej; Berbeć, Adam KleofasAgriculture, as a production sector, is exposed to external shocks. The instability of agricultural markets, changes in prices of inputs, dropping crop prices, or changes in climate patterns put their economic resilience to the test. Agroecological diversification of production is widely cited as a key adaptive strategy to increase farms’ resilience to these shocks. At the same time, empirical evidence linking crop diversity to economic stability across different production systems remains limited. The aim of the study was to assess whether the integration of more complex crop rotations and livestock production increases the economic resilience of organic farms compared to stockless organic farms and conventional farms. The analysis utilized data from the Polish FADN covering the multi-crisis period of 2020–2022, which included the COVID-19 pandemic, Russia’s war against Ukraine, and the sharp rise in fertilizer and energy prices. Farms were grouped by production type. Crop diversity was assessed using the Shannon–Wiener index (H′) and the Pielou evenness index (J′). The economic resilience of tested farms was determined based on their income, income variability during the study period, and the ability to maintain income above the parity threshold. The results indicated the existence of different pathways for building resilience. Organic farms with permanent crops and field crops were characterized by the highest crop diversity on arable land, while organic farms with dairy cows had the highest overall economic resilience, despite relatively low crop diversity on arable land. This phenomenon can be explained by the high proportion of permanent grasslands, which promoted feed self-sufficiency and the internal circulation of nutrients. The results indicate that in organic systems, the integration of crop and livestock production, based on permanent grassland, may be a more effective way to strengthen economic resilience than crop diversification on arable land alone.Item Koncentracja i polaryzacja produkcji rolniczej w Polsce w aspekcie wdrażania WPR(Instytut Uprawy Nawożenia i Gleboznawstwa Państwowy Instytut Badawczy, 2018) Madej, AndrzejItem Koncentracja i polaryzacja produkcji rolniczej w Polsce w aspekcie wdrażania WPR(Instytut Uprawy Nawożenia i Gleboznawstwa Państwowy Instytut Badawczy, 2018) Madej, AndrzejItem Microbial Fertilizing Products Impact on Productivity and Profitability of Organic Strawberry Cultivars(MDPI, 2024) Nakielska, Małgorzata; Berbeć, Adam Kleofas; Madej, Andrzej; Feledyn-Szewczyk, BeataPoland is a major producer of various fruits, including strawberries. As growing consumer awareness of food quality, health, and wellbeing is increasing, farmers are receiving a new market opportunity for organic products of good quality. The integration of microbial solutions into agricultural practices can foster the transition of agricultural farms towards more resilient and sustainable production of quality food. The objective of this study was to assess the influence of novel microbial biopreparations (microbial fertilizing products) containing Bacillus sp., humic acids, and other organic compounds on the economic viability of three strawberry cultivars (‘Honeoye’, ‘Vibrant’, and ‘Rumba’) under organic farming conditions. This study was conducted in 2021 as a field experiment. Irrigated and non-irrigated strawberries were treated with five microbial fertilizing products (K2–K6). The single plot area was 16 m2, with a total of 144 plots. The adopted planting density of strawberries was 30,052 per hectare. K3 treatment was found to be the most universal microbial treatment in terms of positive impact on yields, with significant yield increase on both the non-irrigated (yield increase of 3.76 t·ha−1) and irrigated experiments (yield increase of 5.78 t·ha−1). The K4 treatment on the non-irrigated strawberries resulted in a yield increase of 4.96 t·ha−1, which at the same time had no effect on the yield of the irrigated experiment. On average, application of the K2–K6 combinations on the non-irrigated strawberries resulted in a yield increase from 13.4% (K2) to 33.5% (K4). The irrigated strawberries showed a yield increase from 3.9% (K4—non-significant yield increase) to as much as 36.1% (K3). The highest direct surplus for the non-irrigated strawberries was recorded for the K4 treatment (38,603 PLN·ha−1) and for K3 for the irrigated experiment (42,945 PLN·ha−1). The direct surplus for ‘Rumba’ and ‘Vibrant’ was higher than for ‘Honeoye’ on both the irrigated (22% and 53%, respectively) and non-irrigated (19% and 18%, respectively) experiments. The average profitability index for all tested non-irrigated and irrigated varieties improved when treated with microbial fertilizer products, with profitability indexes of 143.3–168.8% on the non-irrigated plantation and 129.2–169.7% on the irrigated plantation. The tested microbial fertilizing products proved to be valuable products to improve the productivity and economic effectiveness of organic strawberry production. At the same time, their use needs to be adapted to local plantation conditions.Item Możliwości ograniczenia strat biogenów poprzez optymalizację nawożenia w warunkach rolnictwa precyzyjnego w Polsce(Instytut Uprawy Nawożenia i Gleboznawstwa Państwowy Instytut Badawczy, 2022) Madej, Andrzej; Pecio, AlicjaItem Obecna sytuacja i perspektywy uprawy tytoniu w Polsce na tle świata i Unii Europejskiej(Instytut Uprawy Nawożenia i Gleboznawstwa Państwowy Instytut Badawczy, 2012) Berbeć, Apoloniusz; Madej, AndrzejItem Ocena efektywności nawożenia mineralnego z uwzględnieniem ujęcia przestrzennego(Instytut Uprawy Nawożenia i Gleboznawstwa Państwowy Instytut Badawczy, 2015) Madej, AndrzejItem Ocena stopnia zrównoważenia indywidualnych gospodarstw rolnych o różnych kierunkach produkcji(Instytut Uprawy Nawożenia i Gleboznawstwa Państwowy Instytut Badawczy, 2014) Harasim, Adam; Kopiński, Jerzy; Madej, Andrzej; Matyka, MariuszItem Ocena zmian produkcyjnych i organizacyjnych w polskim rolnictwie w latach 2004-2014(Instytut Uprawy Nawożenia i Gleboznawstwa Państwowy Instytut Badawczy, 2016) Madej, AndrzejItem Ocena zmian użytkowania gruntów rolnych, struktury zasiewów oraz powierzchni rolnictwa ekologicznego w perspektywie do 2030 r. w kontekście ograniczenia strat biogenów(Instytut Uprawy Nawożenia i Gleboznawstwa Państwowy Instytut Badawczy, 2022) Jończyk, Krzysztof; Stalenga, Jarosław; Kopiński, Jerzy; Madej, AndrzejItem Organizacyjno-ekonomiczne uwarunkowania produkcji zbóż w różnych regionach Polski(Instytut Uprawy Nawożenia i Gleboznawstwa Państwowy Instytut Badawczy, 2020) Krasowicz, Stanisław; Madej, AndrzejItem Organizacyjno-ekonomiczne uwarunkowania produkcji zbóż w różnych regionach Polski(Instytut Uprawy Nawożenia i Gleboznawstwa Państwowy Instytut Badawczy, 2020) Krasowicz, Stanisław; Madej, AndrzejItem Organizacyjno-ekonomiczne uwarunkowania produkcji zbóż w różnych regionach Polski(Instytut Uprawy Nawożenia i Gleboznawstwa Państwowy Instytut Badawczy, 2020) Krasowicz, Stanisław; Madej, AndrzejItem Porównanie gospodarki paszowej w wybranych gospodarstwach woj. podlaskiego w latach 2002 i 2013(Instytut Uprawy Nawożenia i Gleboznawstwa – Państwowy Instytut Badawczy w Puławach) Madej, AndrzejItem PROFITABILITY OF WINTER WHEAT AND SUGAR BEET PRODUCTION IN IUNG-PIB FARMS(Instytut Uprawy Nawożenia i Gleboznawstwa – Państwowy Instytut Badawczy w Puławach) Harasim, Adam; Madej, Andrzej
