The Bydgoszcz region (Poland) is located in an area with a very high demand for supplementary irrigation during the vegetation period of plants. The projected global warming will bring a rise in the water needs of crops, and thus a further increase in irrigation needs. The goal of the study was an attempt to estimate the water needs of sweet cherry...

Most scenarios of climate change in Poland predict an increase in air temperature in the coming years. However, no significant increase in precipitation is forecast. Therefore, an increase in the water needs of plants should be expected, which requires the development of irrigation systems. To precisely determine the schedule of crop irrigation, it...

The climatic changes observed in Poland are manifested by an increase in air temperature, but not an increase in rainfall, which causes an increase in the water needs of plants, and hence the necessity to develop irrigation systems for crops. The aim of this study was to assess the water needs of grapevines in 2021–2050 in the Bydgoszcz region (nor...

Code of Good Agricultural Practises in Water Management

According to the SRES A1B climate change scenario, by the end of the 21st century temperature in Poland will increase by 2-4°C, no increase in precipitation totals is predicted. This will rise crop irrigation needs and necessity to develop irrigation systems. Due to increase in temperature and needs of sustainable agriculture development some chang...

Giant miscanthus is a vigorously growing energy plant, popularly used for biofuels production. It is a grass with low soil and water requirements, although its productivity largely depends on complementary irrigation, especially in the first year of cultivation. The aim of the study was to assess the impact of the forecast climate changes, mainly a...

Irrigation Advisory Services (IAS) are powerful management instruments aiming to achieve the best efficiency in irrigation water use. So far the literature on farmers’ preferences for a specific scheme design of IAS’ characteristics and the related willingness to pay (WTP) is scant. This study provides evidence on farmers’ preference towards six at...

Climate warming increases the water needs of plants. The aim of this study was to estimate the water needs of grapevines in central Poland. Water needs were calculated using the crop coefficients method. Reference evapotranspiration was assessed by the Blaney–Criddle’s equation, modified for climate conditions in Poland. Crop coefficients were assu...

Climate changes lead to a rise in air temperature, which significantly increases the water needs of plants. Maintaining crop productivity will increasingly require the use of plant irrigation. The aim of this study was to assess the water needs of grapevines cultivated in the western provinces of Poland. The calculations were made on the basis of t...

The goal of this study was to assess the water needs of elderberry. The investigation included elderberry plants that had been planted in land reclamation areas more than three years earlier. The water needs were evaluated for 5 agro-climatic regions of Poland. The calculations were based on the observation of meteorological conditions in the years...

Black locust, considered an ornamental plant, is often used in the soil reclamation process, because it enriches the soil with nitrogen. High seedling survival rate in the first stage of reclamation depends mainly on sufficient water conditions controlled by irrigation, which in turn requires determining the plant’s water needs. The aim of the rese...

The ash-leaved maple (Acer negundo L.) has low habitat requirements, which is why this species is often used in the reclamation of industrial areas. The development of the reclamation plantings depends on the optimal water soil conditions that can be controlled by watering treatments. However, the use of irrigation requires determining the water ne...

Precipitation totals at annual and monthly scale are key elements affecting water availability for a number of human activities. Thus, the multi-year variability and probability distribution of precipitation form the basis information for water management and damage risk assessment (caused by drought and heavy rains). The main goal of this paper is...

We noticed...

Studies were carried out in three different grassland sites near Bydgoszcz in Poland: wet site in fluvial soil in the Vistula River valley (Grabowo), wet periodically dry site in peat-moorsh soil (Frydrychowo) and dry site in mineral-moorsh soil (Prądki), both in the Noteć River valley. Measurements carried out in the dry site in mineral soil (Bydg...

The aim of the paper was to estimate the spatial variability of climatic and agricultural water balance for two-cut meadows (for two hay yield: 5 and 7 Mg ha-1) in different agro-climatic regions in Poland. It let to estimate meadow water needs under different meteorological conditions. The climatic water balance is a difference between precipitati...

Abstract: Climatic and agricultural water balance for grasslands in Poland using the Penman-Monteith method. The aim of the paper was to estimate the spatial variability of climatic and agricultural water balance for two-cut meadows (for two hay yield: 5 and 7 Mg ha-1) in different agro-climatic regions in Poland. It let to estimate meadow water ne...

The study was focussed on the effect of the draining depth, at variable intensity of ground water input and climatic conditions in Poland, on the prolongation of excessive, sufficient and insufficient moisture content in the rhizosphere of moderately mineralised soil under extensively used 2-cut meadow. Practical problem consisted in looking for "t...

MARS Crop Yield Forecasting System (MCYFS) is an analytical tool running operationally. It is used for forecasting the yield of important agricultural crops in the European Union and neighbouring countries. The system provides timely information about weather conditions, plant parameters (such as biomass accumulation) on the basis of satellite imag...

The influence of draining depth of extensively used peat-moorsh soil at times of duration of characteristic soil moisture in the root layer was examined in the investigation.
