Pseudogley is a soil type that is under natural conditions characterized by unfavorable properties, the most pronounced being insufficient amounts of basic plant nutrients. Using different amelioration measures, numerous researchers have tried to overcome the problems resulting from soil acidity (increased aluminum and manganese contents, deficiency of alkaline cations in the adsorption complex and reduced available phosphorus content). Calcification was the most common measure almost always producing the best results of all the measures. In order to determine the effect of some neutralization acidity materials derived from natural sources (bentonite zeolite, lifos, CaO and MgO) on the change in the available phosphorus and potassium contents, a trial was set up on extremely acid soil to determine the manner of change in the nutrients concentrations in maize leaf and grain. The results obtained show that all ameliorative measures used affected the soil phosphorus and potassium contents increase, depending on the reduction of acidity and the mobile aluminum content, resulting also in a better uptake of the nutrients from the soil.

The pot experiment was established in vegetation hall in the year 2015. Spring barley, variety KWS Irina, was grown. Two different soils – chernozem from Brno (with a low phosphorus content and alkali soil reaction – 7.37) and haplic luvisol from Jaroměřice nad Rokytnou (with a high phosphorus content and slightly acid soil reaction – 6.01) were used for comparison. The rates of phosphorus in the form of triple superphosphate (45 % P2O5) were increased from 0.3 – 0.6 – 1.2 g per pot (5 kg of soil – Mitscherlich pots). Nitrogen was applied in the form of CAN (27 % N) at a rate of 1 g N per pot in all the treatments incl. the control. Using statistical analysis, significant differences were found between the two soil types both in terms of the postharvest soil P content and yields of aboveground biomass. The content of post‑harvest soil phosphorus increased significantly with the applied rate (96 – 141 – 210 mg/kg in chernozem and 128 – 179 – 277 mg/kg in haplic luvisol). Dry matter yields of the aboveground biomass grown on chernozem were the lowest in the control treatment not fertilised with P (38.97 g per pot) and increased significantly with the P rate applied (46.02 – 47.28 g per pot), although there were no significant differences among the fertilised treatments. On haplic luvisol phosphorus fertilisation was not seen at all, demonstrating that the weight of the biomass in all the treatments was balanced (48.12 – 49.63 g per pot).

Temporal changes in the concentrations of plant-available phosphorus (P) in soil (Olsen-P), total soil-P and P activation coefficient (the ratio of Olsen-P to residual-P (i.e. an approximation to total-P)) were measured in plots that received consistent inorganic nitrogen, phosphorus and potassium plus organic fertilizers annually. Maize and winter wheat crops were grown in rotation for 24 years. Olsen-P and P activation coefficient declined significantly in the earlier years (< 12 years) for treatments that did not include any P fertilizer, and increased over the same period for the P-fertilized treatments. The rates of change in the Olsen-P and P activation coefficient values were positively related to P balance. In the later years, the Olsen-P and P activation coefficient plateau values were positively related to the P balance.

Potato can be grown on a large number of soil types. In order to determine the suitability of leached soils for potato growing in Western Serbia, a trial was set up with the aim of observing agrophysical and agrochemical properties of this type of soil in the region of the Radočelo mountain massif in 2020. Three soil profiles were opened. Results pointed out that leached soils of Western Serbia are suitable for potato growing according to their agrophysical properties, but unfavourable as regards some agrochemical parameters (a low content of available phosphorus, high values of active, exchangeable, and hydrolytic acidity). Nevertheless, it is possible to achieve high yields that approach the biological potential of potato using appropriate soil amendment practices (timely application of proper amounts of the complex NPK fertiliser with increased phosphorus and potassium levels, basal liming of the soil along with manuring, and use of physiologically neutral nitrogen fertilisers).

Limestone, nitrogen, phosphorus and potassium, alone and in various combinations, were applied to the surface of permanent hayland during a 27-year period. Both limestone and phosphorus produced marked changes in the chemical properties of the soil. Phosphorus content of the soil where surface applications of this fertilizer were made decreased markedly with depth of sampling. Yield response to phosphorus was greater than to nitrogen or potassium although changes in botanical composition of the sward indicated the value of nitrogen, for grass and of limestone for legumes. Irrespective of the treatment, yields declined with time.

Topography-induced microclimate differences determine the local spatial variation of soil characteristics as topographic factors may play the most essential role in changing the climatic pattern. The aim of this study was to investigate the spatial distribution of soil organic carbon (SOC) with respect to the slope gradient and aspect, and to quantify their influence on SOC within different land use/cover classes. The study area is the Region of Niš in Serbia, which is characterized by complex topography with large variability in the spatial distribution of SOC. Soil samples at 0–30 cm and 30–60 cm were collected from different slope gradients and aspects in each of the three land use/cover classes. The results showed that the slope aspect significantly influenced the spatial distribution of SOC in the forest and vineyard soils, where N- and NW-facing soils had the highest level of organic carbon in the topsoil. There were no similar patterns in the uncultivated land. No significant differences were found in the subsoil. Organic carbon content was higher in the topsoil, regardless of the slope of the terrain. The mean SOC content in forest land decreased with increasing slope, but the difference was not statistically significant. In vineyards and uncultivated land, the SOC content was not predominantly determined by the slope gradient. No significant variations across slope gradients were found for all observed soil properties, except for available phosphorus and potassium. A positive correlation was observed between SOC and total nitrogen, clay, silt, and available phosphorus and potassium, while a negative correlation with coarse sand was detected. The slope aspect in relation to different land use/cover classes could provide an important reference for land management strategies in light of sustainable development.

Soil samples (n = 11) were collected in the chernozem areas of the Czech Republic (the Central Europe) from the topsoil and used as representative samples. All sampling areas have been used for agricultural purposes (arable soil) and they were selected as typical representatives of agricultural soil. These samples represented the soil with same genesis (to reduction differencies between soil types) but with different soil properties (physical and chemical). Complete chemical and physical analyses were made for confirmation of copper adsorption on solid phase: we analysed the particle size distribution, content of oxidizable carbon (Cox), the cation exchange capacity (CEC), supply of exchange calcium, magnesium, sodium, phosphorus and potassium, soil reaction and the total supply of Fe, Al, Mn, Ca, Mg, K, P and N. The strongest simple correlation between analysed soil properties and copper concentration had content of available magnesium (r = 0.44) and available phosphorus (r = −0.51). In the case of multiple correlations (i. e. collective influence of multiple soil properties) had the strongest influence combination of clay, soil reaction, total content of phosphorus, available magnesium and available phosphorus. The main influence of phosphorus and magnesium is evident. We suppose that copper and phosphorus enter into specific complex. Influence of these five soil properties can explain 92.7 % (r = 0.927) changes in the content of copper changes in the experiment.
