The paper summarises the results of the comprehensive scientific research carried out in the form of a two-factor stationary experiment (5 primary tillage systems × 3 fertilization systems) with rotation (2016–2020) of cereal crops (winter wheat – grain maize – spring barley – soybean) in grey forest fine sand and light loam soil. The effectiveness of the tested agricultural production method has been proven by the amplitudes of the actual cropping capacities: winter wheat – 2.80–5.00 t∙ha–1; grain maize – 4.16–8.89 t∙ha–1; spring barley – 1.78–4.45 t∙ha–1; soybean – 1.02–3.17 t∙ha–1. The rehabilitation of the physical, agrochemical and biological status of the edatope and the consolidation of the physiological processes in the grain cenoses achieved by the systemic approach to the soil tillage and fertilisation have provided for an increase in the natural biological potential of the plough land by a factor of 1.3–1.8 (from 2.96 to 5.21 t∙ha–1 of grain units, units for the equivalent measuring of different plant cultivation products). Factographic justification has been provided for the environmental, technological and technical-and-economic feasibility of implementing agronomic technologies based on the adaptive combination of mouldboard and non-mouldboard tillage (to a depth of 6–45 cm) and organic and mineral fertilization system (6.5–7.0 t∙ha–1 of plant cultivation by-products + N70P58K68). In this case, the effective fertility of an area unit in crop rotation reaches 5.72 t∙ha–1 in grain units, the production cost of raised grain – 117 €∙t–1, the earning capacity – 788 € (ha∙year) –1, the level of plant cultivation profitability – 139%. In the comparable alternatives of the system-based soil tillage (every-year ploughing, subsurface blade tillage and especially tillage with disk implements), the indices estimated above are significantly lower.

We present in this work a detailed design of a small low-pressure chamber outfitted with a ceramic porous plate for evaluating the soil water retention curve (SWRC) in the water potential range from 0 to -100 kPa. The chamber is made of acrylic and permits the use of one unique soil sample each time. The use of this chamber allows quick measurements of soil moisture using nuclear (based on gamma-ray attenuation) and conventional methods and SWRC determinations made with the designed chamber are in agreement with those obtained using a commercial low-pressure chamber. The chamber was designed especially for testing the use of the nuclear method as an auxiliary tool for SWRC determinations but it can be easily adapted for routine investigations and a practical alternative for the conventional SWRC method.

The paper presents the results of measurements of some chemical properties for 14 drained fen peat-moorsh layers taken from north-east, central and east part of Poland. These areas were drained in order to use as a grassland and most of them in former time were under subirrigation systems. The following basic chemical properties were analysed: organic C, total N, C:N ratio, pH and ash content. In the paper also the relationships between some basic chemical and physical properties were analysed (ash content with bulk density, particle density and porosity). Increasing of ash content caused the decreasing of some chemical properties (organic carbon and total nitrogen content) and increasing some physical properties (bulk density and particle density).

Próby do analiz pobrano z 14 warstw odwodnionych gleb torfowo-murszowych zlokalizowanych w północno-wschodniej, centralnej i wschodniej Polsce znajdujących się w zasięgu funkcjonujących w przeszłości systemów melioracyjnych. W pracy przedstawiono wyniki badań wybranych właściwości chemicznych (węgiel organiczny, azot ogólny, stosunek C:N, popielność) oraz relacje pomiędzy badanymi właściwościami chemicznymi a wybranymi właściwościami fizycznymi (zależność popielności od gęstości gleby, gęstości fazy stałej, porowatości). Wzrost zawartości popielności z poziomu 10 do 40% a.s.m. pociąga za sobą zmniejszenie się zawartości węgla organicznego, azotu ogólnego i porowatości, powoduje natomiast wzrost wartości gęstości objętościowej gleby oraz gęstości fazy stałej.

In this paper a model is proposed for water retention prediction with soil structure parameters. It is a correlation model in which the parameters are: bulk density, specific surface area, proportional content of silt and clay as well as proportional content of water-stable aggregates of sizes 1-3, 3-5 and 5-10 mm.

Changes in water retention curves caused by an addition of a soil conditioner (Solacrol) are discussed. The investigations were carried out on the different size aggregates of two types of soils. It was stated that stabilisation of soil aggregates changed the courses of water retention curves. The use of Solacrol generally caused a significant increase of retained water (above 5%) in case of Orthic Luvisol aggregates smaller than 3 mm for pF values below 2 and Haplic Phaeozem aggregates smaller than 0,5 mm for pF values below 1.5.
