Opis:
The paper presents comparative characteristics of the length as well as start and end dates of the forest vegetation period (FVP) in the years 1981−2010 determined on the basis of the average daily air temperature and data generated for the conditions of two−fold higher CO2 concentration. To simulate meteorological data for that conditions, we applied the WGENK data generator, considering assumptions of GISS Model E scenario of climate change. The results showed that the average start date of FVP in Poland in the period of 1981−2010 was April 25th, while the average end date of FVP was October 10th. The average length of FVP for Poland equalled 165 days. It was discovered that, on average, the FVP start accelerated by 8 days per 30 years and the FVP end was slightly delayed by 3 days per 30 years. During the analyzed period, the FVP in Poland extended by 10 days on average. According to the applied scenario of the climate change, the trend indicates a possible increase in the FVP by 30 days when compared to the present state. The FVP may start 2−3 weeks earlier and finish 1−2 weeks later than presently. The generated data pointed at April 9th as the average date of the FVP start and October 24th as the date of its end.

Opis:
The article contains descriptive statistics on rainfall in an area of the southern part of the last ice age in Europe, and which now comprises the north-eastern part of the Poland. The study covers the period of 1981-2010. The sums of the annual and monthly precipitation were calculated, while years and months were evaluated in relation to the multi-annual and monthly averages. The frequency of daily precipitations was also determined. Values of SPI (Standarized Precipitation Index) were calculated together with the values of the Selianinov Index, which measures the environmental aspect of precipitation. The average annual rainfall showed a spatial heterogeneity in the region from 700.1 mm (Elblag in the north-west) to 555.3 mm (Mława) in the east and south-east. The greatest precipitation occurred in the last decade of the analysed period of thirty years. However, statistical analysis shows no significant trend change in precipitation during this period. The number of years with sums of precipitation below 75% of the normal turned out to be very small. In the annual cycle, summer precipitation prevailed. On a monthly basis, the averages sometimes exceeded the multiyear averages by as much as 200%, while extreme lows in monthly precipitation reached levels below 25% of the long-term averages. The calculated value of the SPI indicated that the most common drought conditions occurred in May and June; such droughts did not occur in April and July. The Selianinov Index indicates that the least favorable hydrothermal conditions occur in April and May, while the most favorable conditions occur in August and September.

Opis:
Nutrients dissolved in water and not taken by plants leach into deeper soil layers or flow out to surface water through pipe drainage systems, causing ground or surface water contamination. Thus, drainflow from agricultural areas has significant influence on surface water eutrophication. The objectives of this study were to evaluate nitrate nitrogen and phosphate concentrations and load changes in drainflow using as an example clay soil analyzed in period spanning the years 2010 and 2013. Field research was conducted at an experimental site in Lidzbark Warmiński, in the Province of Warmia and Mazury (województwo warmińsko-mazurskie) in Poland. Mollic Gleysols developed from loam and clay dominate in this area. The experimental field has a tile drainage system with 21 m drain spacing and average 0.9 m drain depth. Winter wheat (Triticum L.) and oilseed rape (Brassica napus) were cultivated in 2009–2012 and in 2012–2013, respectively. Chemical analysis of water samples was performed with a Hach Lange DR 3900 spectrophotometer. Annual rainfall ranged from 555 mm in 2013 to 814 mm in 2012. Average nitrate nitrogen daily loads ranged from 0.07 to 0.58 kg ha-1, while the total annual nitrate load varied from 7.5 to 34.6 kg ha-1. Daily loads of phosphate were about ten times lower than daily loads of nitrate and the total annual phosphate load ranged from 0.1 to 2.0 kg ha-1. Neither nitrate nor phosphate concentrations are strongly depended on drainflow, but the nitrate nitrogen concentration indicates some relationship with the season. A substantial increase in the nitrate nitrogen concentration appears at snow melting (March) and continues until the end of May, peaking in the third decade of April, when the cultivated crops begin the vegetative growth. The phosphate concentration did not undergo significant changes during the investigated period.

Opis:
The paper intends to show the potential of diverse benefits of two water quality indices used to assess 4 dammed lakes in lowland area in NE Poland: the Water Quality Index (WQI), developed by the Scottish Development Department, used in the assessment of water potential for human consumption, fisheries, industries and recreation, as well as the Sodium Adsorption Ratio (SAR), recommended by the Salinity Laboratory of the US Department of Agriculture, used in the water assessment for the irrigation purpose. Our study was based on the results of a water quality monitoring programme, in which the following water parameters have been analyzed: pH, dissolved oxygen, electrical conductivity, biological oxygen demand, chemical oxygen demand, NH4 +, NO3 -, Cl-, SO4 2-, Na+, Ca2+, Mg2+ and HCO3-. The water quality parameters differed among the studied reservoirs, and represented a medium (Wykrot) and poor class (Grodzisk Duży, Karwacz and Łoje) on a 5-degree WQI scale. The SAR was less diversified and water in the studied reservoirs showed class I. The results revealed that the water in all the reservoirs is suitable for irrigation with no hazard to the soil structure as well as for breeding of fish that tolerate lower water aeration. This water can be also used for recreational purposes, although direct contact with water is not recommended. The water quality indices (WQI and SAR) showed a great potential in the assessment of water for multi-purpose usage. The WQI and SAR are excellent tools for summarizing overall water quality conditions over space and time. When used together, they are also a method of providing relevant information for specific water use that can be more readable for planners and managers.

Opis:
Contemporary and archive cartographic materials illustrating horizontal profile of the middle channel of the Narew River (between Ostrołęka and Łomża) were compared in the GeoMedia application. The results of the analysis revealed that natural and anthropogenic factors had not significantly contributed to changes in the channel profile over a period of two centuries. Narew is a meandering river, and its activity is associated with intensified erosion of right-bank bends and lateral movement along its flat-bed channel. The most noticeable changes include reduced area of oxbow lakes, mainly due to succession, and suburban settlement in floodplains that had been regarded as unfit for development in the 20th century.

Opis:
The volume and quality of cereal yields are largely determined by the course of climatic conditions, mainly air temperature and precipitation. The objective of this paper was to determine the impact of meteorological conditions during the spring and summer growing season of winter wheat on grain yields (in 1993-2012) and on the content of nutrients in grain (in 1994- 2009). The study was based on a field experiment conducted at the Research Station located in Tomaszkowo near Olsztyn, which belongs to the University of Warmia and Mazury in Olsztyn. The impact of meteorological parameters during the spring and summer season on winter wheat yields and the content of elements was investigated by correlation analysis and multiple regression analysis. The examined weather conditions in the spring and summer did not produce any significant impact on the yields. However, some tendencies were noted, indicating that the average minimum temperature had the highest negative impact and the number of days with precipitation produced the highest positive impact on winter wheat yielding. Among the tested macroelements (N, P, K, Mg, Ca), the analyzed meteorological parameters significantly affected the content of nitrogen and phosphorus in winter wheat grain. The accumulation of nitrogen was positively influenced by precipitation, yet significantly negatively affected by the minimum temperature during the spring and summer growing season. The mean daily air temperature during that time had a significant negative impact on the concentration of phosphorus in wheat grain, which was significantly positively raised by the average minimum daily air temperature during the growing season.

Opis:
Dynamic development of aquaculture has led to an increasing impact on the status of surface waters. Fish production generates wastes that, at high concentrations, may present a serious risk to the aquatic environment. Studies on the assessment of the impact of water management technologies in trout production on the quality of surface waters were conducted in 2011. Six farms were selected for the studies and were divided into two groups based on water management solutions (n = 3): farms with a flow through system (FTS) and farms with a recirculation aquaculture system (RAS). On all farms, water measurement points were set and they depicted the quality of in-flow water, the quality of water in ponds and the quality of outflow water. The studies did not demonstrate any impact of applied technology on electrolyte conductivity or calcium and magnesium concentrations in outflow water from a trout operation. In addition, it was found that the use of water for production purposes resulted in a slight increase in phosphorus and total nitrogen concentrations in waste waters.

Badaniami objęto wody gruntowe, odpływające siecią drenarską oraz zretencjonowane w oczku wodnym zlokalizowanym na obszarze użytkowanym rolniczo, w części działu drenarskiego obiektu Lidzbark Warmiński na Równinie Sępopolskiej. Badania wykonywano w latach 1998–2000 po zdrenowaniu użytków zielonych oraz w latach 2008–2010, po transformacji gruntu obsianego pszenicą ozimą. Celem badań było określenie zmian jakości wód po zmianie sposobu użytkowania terenu. Badania wykazały, że na skutek zmiany sposobu użytkowania ziemi i zaniechaniu nawożenia mineralnego w oczkach wodnych stwierdzono zmniejszenie stężeń większości składników mineralnych, oraz zwiększenie wartości pH, stężeń potasu, magnezu siarczanów i wodorowęglanów. W wodach gruntowych zanotowano wzrost stężeń mineralnych form azotu, fosforu fosforanowego, potasu, magnezu oraz żelaza ogólnego i wodorowęglanów, zaś zmniejszenie stężeń wapnia, sodu, siarczanów i chlorków. W wodzie drenażowej nastąpił wzrost stężeń większości oznaczanych składników, oprócz azotu amonowego i chlorków
The study included groundwater outflow drainage systems and collected in the pond located at the agricultural use area in the portion of the drainage facility Lidzbark Warminski located on the Sępopolska Plain. The study was performed in two periods: the first one was in 1998–2000 (just after was made drainage), in which the discussed area was used as pasture, and the second in 2008–2010, in which after plowed of the soil was cultivated winter wheat. The aim of the study was to determine changes in water quality after the change of the way of land use. Examinations showed that as a result of the change of the way of using the area and ceasing of mineral fertilizing in waters of the pond was a reduction in the concentrations of the most mineral components, but an increase of pH reaction and concentrations of potassium, magnesium of sulfates and bicarbonates. In groundwaters observed increased the content of concentrations of mineral forms of nitrogen, phosphatic phosphorus, potassium, magnesium, general iron and bicarbonates, and a reduction in the concentrations of calcium, sodium, sulfates and chlorides. However in the water which outflow from drainage pipelines system from the research area was an increase of concentrations most of the determined substances, apart from ammonia nitrogen and chlorides.

Opis:
Analysis of the effect of meteorological factors on the yielding of pea cv. Fidelia was conducted for the period of 1986-2005. The source material concerning the yields and the weather conditions originated from three experimental and meteorological stations situated in northern and eastern Poland. In the study the method of multiple regressions was applied, with the use of linear and quadratic functions with stepwise selection of variables, and the created regression equations were evaluated by means of the coefficient of determination R2, adjusted R2 adj and the Cross Validation procedure – R2 pred, as well as the F-Snedecor test. In the years of the study notable variation was observed in the weather factors in the individual stages of growth of pea, which had a significant effect on the times of their beginning, on the duration of the growth stages, and on the level of yields. The effect of the meteorological factors studied, i.e. solar radiation, air temperature and atmospheric precipitations on the yielding of the pea cultivar was related to the location of the station, stage of advancement of vegetation, and on the set of variables adopted for the analyses.
Analizę wpływu czynników meteorologicznych na plonowanie grochu siewnego odmiany Fidelia prowadzono dla wielolecia 1986-2005. Materiał źródłowy dotyczący plonowania i warunków pogodowych pochodził z trzech stacji doświadczalnych i meteorologicznych, zlokalizowanych w północnej i wschodniej Polsce. W badaniach zastosowano metodę regresji wielokrotnej z użyciem funkcji liniowej i kwadratowej z krokowym wyborem zmiennych, a utworzone równania oceniono za pomocą współczynnika determinacji R2, poprawionego R2adji procedury Cross Validation – R2pred oraz testu F-Snedecora. W latach badań obserwowano wyraźne zróżnicowanie czynników pogodowych w poszczególnych okresach rozwoju grochu siewnego, co miało znaczący wpływ na terminy ich rozpoczęcia, długość okresów międzyfazowych oraz wysokość plonowania. Oddziaływanie badanych czynników meteorologicznych, tj. promieniowania słonecznego, temperatury powietrza i opadów atmosferycznych na plonowanie odmiany było uzależnione od lokalizacji stacji, zaawansowania wegetacji oraz od zestawu zmiennych objaśniających przyjętych do analiz.
