Fertilization Level

Soil tillage and fertilization level are important in the system of agro-technical measures that increase soil fertility and sugar beets productivity. Today the cultivation of this crop requires a great deal of expense, therefore, there is a need for a wider study of the use of cheap soil cultivation, soil protection, energy-saving soil tillage technologies and appropriate ferti-lization levels. Under western Forest-Steppe of Ukraine conditions, investigations were conducted on dark grey podzolic light loamy soils where the influence of tillage models and fertilization levels on the formation of sugar beets root crops was studied. Shallow no-plow tillage of the soil on 14-16 cm is expedient to use as a main tillage under sugar beets. Under favorable weather and climatic conditions, it can provide yielding capacity at the level of deep fall plowing. The use of shallow no-plow tillage helped to increase the yielding capacity of sugar beet roots relative to plowing by 28-30 cm for 1.3 t / ha and the biological sugar output – for 0.2 t / ha. Then the sugar content was by 0.1% higher in the application of deep fall plowing on 28-30 cm. The optimization of the system of sugar beets fertilization allows ensuring the growth of the yielding capacity of root crops. It is established that the application of fertilizer norm N300P225K350 provides the yielding capacity at the level of 90 t / ha. The sugar content of root crops at the given fertilizer rate was the lowest in the experiment - 16.5 – 16.6%. Thanks to the high yielding capacity of root crops in terms of N300P225K350, the sugar harvesting was the highest and depending on the method of basic soil tillage was 14.95 – 14.79 t / ha. That is in 3.2 times more as to the control, in 1.3 times more than the norm of N180P135K210 and in 1.1 more than the fertilization level N240P180K280.

The national soil monitoring network (Nabo) consists of 105 sites across Switzerland, 28 of which are located in forests. After 25 years already seven forest sites (25%) were more or less damaged by storms. Two of them had to be abandoned for a decade to recover. Concerning precautionary soil protection the legal guide value is exceeded at three forest sites for cadmium and at one site also for chromium. These sites are all based on Jurassic limestone, and it is well known that residuals of limestone weathering can be rich in cadmium. Hence, the enrichment is supposed to be of geogenic origin. In the Canton Ticino the top soil at Novaggio site exceeds the guide value for lead. Here, anthropogenic origin is very likely. The analysis of the organic pollutants PAH and PCB in the third sampling campaign revealed moderate concentrations with a maximum lower than or equal to ⅔ of the corresponding guide value. Based on the results of the first four sampling campaigns it can be concluded that only small changes in the measured heavy metal concentrations in the top soils at the 28 Nabo sites were found. The most dynamic element is lead. Most of the concentrations are far below the guide values, the same holds for the organic pollutants PAH and PCB.

The Creation

Soil protection in agrolandscapes is especially necessary in conditions of intensification of production and increasing anthropogenic pressure on them. This complex should fit into the landscape farming system. The more intensive the load on the land in the farm, the higher the level of soil protection against destruction. The article notes that raising soil fertility, increasing crop yields and ecological environmental improvement are possible only on the basis of agrolandscape farming system, which allows to establish the correct ratio of arable land, meadows and forests. The transition to such a system of agriculture requires: development of a project for agrolandscape land management with a set of anti-erosion measures for each farm; adjusting the structure of sown areas taking into account market conditions, that is, increasing the area of productive crops in demand (winter and spring wheat, perennial grasses), which in combination with occupied and green manure pairs determine the structure of biologized crop rotation; widespread use of legumes (peas, vetch) as factors in the biologization of agriculture. The efficiency of expanding the area of perennial grasses to 25 % of arable land in some areas of the Non-Chernozem region and the Belgorod region is shown. Here, techniques that increase the efficiency of arable land are based on strict adherence to crop rotation with legumes, the use of adaptive varieties, and the use of biologized fertilizer and plant protection systems. It is noted that the creation of a system of shelterbelts makes it possible to reduce the cost of planting and growing them in comparison with single forest belts and what is very important for farmers is to sharply increase the return on their exploitation in the form of increased increases in crop yields. The creation of forest-sized landscapes will improve the environmental conditions for the cultivation of crops.

Soil Recovery

Engineering applications can be used to mitigate the adverse effects of soil compaction and amend compacted soils. Previous literature has highlighted the beneficial effects of interventions such as litter mulching and incorporation on skid trails. However, little is known about the effectiveness of these alternatives in restoring forest soil quality after forest logging. The objective of this study was to properly elucidate the effects of the above mentioned soil protection methods, litter incorporation before skidding (LI) and litter mulching after skidding (LM), on the recovery of compacted soil’s physico-chemical and biological properties on skid trails over a 2-year period in the Hyrcanian forests of Iran to identify the best option for restoration intervention. The litter used in both methods consisted of dried leaves of the hornbeam and maple tree in three intensities of 3, 6, and 9 Mg ha−1. The results showed that the application of both methods (LI and LM) significantly improved the soil properties when compared to the untreated skid trail. Results showed that the recovery values of soil properties in the LI treatments were significantly higher than those of the LM. The recovery values of soil properties by 6 and 9 Mg ha−1 were significantly higher than those of 3 Mg ha−1, while the differences were not significant between 6 and 9 Mg ha−1. Our findings showed that soil properties were partially recovered (70–80%) over a 2-year period from treatment, compared to untreated, but the full recovery of soil properties required more time to return to the pre-harvest value. Overall, the results of this study demonstrated that the application of soil protection methods accelerates the process of recovering soil properties much faster than natural soil recovery, which can take more than 20 years in these forests.

AbstractSoil degradation due to erosion is a significant worldwide problem at different spatial (from pedon to watershed) and temporal scales. All stages and factors in the erosion process must be detected and evaluated to reduce this environmental issue and protect existing fertile soils and natural ecosystems. Laboratory studies using rainfall simulators allow single factors and interactive effects to be investigated under controlled conditions during extreme rainfall events. In this study, three main factors (rainfall intensity, inclination, and rainfall duration) were assessed to obtain empirical data for modeling water erosion during single rainfall events. Each factor was divided into three levels (− 1, 0, + 1), which were applied in different combinations using a rainfall simulator on beds (6 × 1 m) filled with soil from a study plot located in the arid Sistan region, Iran. The rainfall duration levels tested were 3, 5, and 7 min, the rainfall intensity levels were 30, 60, and 90 mm/h, and the inclination levels were 5, 15, and 25%. The results showed that the highest rainfall intensity tested (90 mm/h) for the longest duration (7 min) caused the highest runoff (62 mm3/s) and soil loss (1580 g/m2/h). Based on the empirical results, a quadratic function was the best mathematical model (R2 = 0.90) for predicting runoff (Q) and soil loss. Single-factor analysis revealed that rainfall intensity was more influential for runoff production than changes in time and inclination, while rainfall duration was the most influential single factor for soil loss. Modeling and three-dimensional depictions of the data revealed that sediment production was high and runoff production lower at the beginning of the experiment, but this trend was reversed over time as the soil became saturated. These results indicate that avoiding the initial stage of erosion is critical, so all soil protection measures should be taken to reduce the impact at this stage. The final stages of erosion appeared too complicated to be modeled, because different factors showed differing effects on erosion.
