In accordance with the National Program for Increasing Forest Cover it is planned to augment Poland’s forest cover to 30% by 2020. This task involves afforestation of agricultural lands by pioneer species that have low habitat requirements, such as the silver birch or the Scots pine. Application of sawdust, clear cutting residues, compost bark and compost beneath tree roots contributed to better development of the assimilation apparatus. The use of mineral fertilizer stimulated tree growth as well as improved physical and chemical properties of soil.

In a multi-year field fertilisation experiment the effects of organic and mineral fertilisers on the physicochemical properties of lessive soil were compared. Manure, two doses of slurry and mineral fertilisers were applied to soil farmed in an eight-field crop rotation. Dose 1 of slurry, manure and mineral fertiliser were applied in doses balanced with nitrogen. Dose II of slurry was determined so that the amount of organic carbon introduced along with it was the same as in the dose of manure. To the experimental facilities with manure and slurry, additional fertilisation with phosphorus and potassium was applied. Following 36 years of annual fertilisation, samples of soil were taken from the 0-25 cm layer, determining the amount of organic carbon and the sorption properties of the soil. It was determined that as a result of applying organic fertilisers, the amount of organic carbon, sorption complex capacity and basic cation content increased whereas hydrolytic acidity decreased. Manure was found to have the most beneficial effect, which was matched by neither dose I nor II of slurry. Additional phosphorus-potassium fertilisation of soil with manure and slurry positively influenced the sum of bases and the total sorption capacity of the soil. Mineral NPK fertilisation led to the decrease in the saturation of bases of the sorption complex and the increase in hydrolytic acidity.

The main objective of this study is to carry out a complex economic analysis of organic manure application. Researches were carried for years 2010-2015. Organic manure, a by-product of animal husbandry, is one of the oldest and most valuable materials in agriculture. The primary purpose of using organic manure is to improve soil fertility. Since the 90s, Hungary has been facing changes in the ownership of agricultural ventures, the number of big farms decreased and the amount of livestock was reduced in the main sectors of animal husbandry. Hungary, as a member of the European Union, has to conform to the current environmental protection regulations which also refer to the disposal of organic manure that can only be performed if significant investments are made. It can be concluded that the economic efficiency of organic manure application is primarily determined by transport distance and the specific transport method. In addition, the establishment of manure containers can be considered to be unproductive investments which affect the economic efficiency of using organic manure negatively.

The present work aimed at investigating diversified organic treatment including sewage sludge on the insecticide activity of enthomopathogenic fungi and nematodes. Crude sludge from biological tannery sewage treatment plant and vermicomposts based on the sludge with added straw and fruit tree leaves were used for the experiment. Organic treatment significantly affected pathogenic properties of enthomopathogenic nematodes naturally present in the soil of the investigated plots. The highest death rate among trap insects was detected in the soil from untreated plots or fertilised by farmyard manure and vermicomposts. Nematodes from examined plots reproduced in varying numbers depending on the treatment applied on individual plots. The lowest number of invasive larvae was obtained for nematodes from plots fertilised by straw vermicompost, (crude)sewage sludge and hair. The applied organic treatment influenced also insecticide activity of the applied nematodes towards G. mellonella larvae. The highest death rate of G. mellonella larvae was observed in the soils treated with organic fertilisers and farmyard manure. Clear decrease in B. bassiana pathogenic properties was detected in soil fertilised with sewage sludge and hair. Chemical sludge and fertilisation with hair caused also a clear decrease in S. carpocapsae pathogenic properties towards G. mellonella larvae. The obtained results reveal unfavourable effects of crude sewage sludge on the pathogenic properties of enthomopathogenic fungi and insects. Vermicomposts obtained from this sludge revealed a positive influence on the microorganisms. This fact may indirectly improve health conditions of plants.

Roseroot (Rhodiola rosea L.) is an important medicinal plant with welldocumented adaptogenic activity. The decrease in its natural resources induces to undertake research on the introduction of this species into cultivation. The aim of the present work was to determine the effect of organic and mineral fertilization on increasing the biomass of underground parts of Rh. rosea and the level of biologically active compounds. Throughout the study period, the highest raw material yield was obtained after the application of the following doses of mineral fertilization: N – 60.0 kg·ha-1, P – 35.2 kg·ha-1, K – 83.0 kg·ha-1, without manure. The use of manure caused a decrease in the average rhizome and root weight by more than 20%. Mineral fertilization application increased the average raw material yield by about 30–40% and allowed obtaining the highest weight of underground organs of the species in question already in the fourth year of cultivation. Furthermore, the present study demonstrates that mineral fertilization does not affect substantially the level of the individual groups of compounds in the raw material, but the use of manure may significantly reduce the content of phenylpropanoids. The level of active compounds is also influenced by crop age. Two-year-old plants were characterized by the highest content of phenylpropanoids as well as by the lowest content of phenylethanoids and phenolic acids. In the following years of cultivation, no statistically significant changes were observed in the level of the analysed groups of compounds.

Badania przeprowadzono w gminie Zamość w roku 2000 i 2001. Obejmowały one dwa gospodarstwa ekologiczne. Próbki gleby spod warzyw, zbóż i roślin pastewnych pobrano na początku września. W próbkach tych oznaczono azot mineralny (formę azotanową(V) i amonową). Przewaga formy amonowej w azocie mineralnym, w stosunku do azotanów, wskazuje na dobre wykorzystanie przez rośliny formy azotanowej i przewagę procesu amonifikacji nad nitryfikacją. Stwierdzono, że intensywne nawożenie organiczne w gospodarstwach ekologicznych, jako źródło azotanów(V), nie zagraża środowisku naturalnemu.

Mineral and organic fertilization is one of the rtiost important factors affecting activity of soil enzymes. It is commonly accepted that organic fertilization is more beneficial to the soil biological activity than the mineral. The objectives of this investigation were to assay Corg, Ntot, Ptot content and to determine urease and amylase activities in the soil fertilised for a long time with various rates of farmyard manure and slurry. Soil samples were taken from the experiment established on a typical lessivé soil. FYM was used at the following rates: 20, 40, 60, 80 t ha-1 fresh weight once in the rotation on the plots with potatoes, while slurry was applied in four doses corresponding to manure fresh weight. Soil samples were taken after potato harvest in the 8th year after the experiment start-up from two depths: 5-15 and 25-35 cm of the soil profile. Usually, higher amounts of Corg and Ptot were found in the soil manured with FYM in comparison with the pig slurry-manured soil. These amounts increased when the doses of both fertilizers were the highest. The content of Corg ranged from 5.5 to 8.2 g kg-1 of soil when 80 t ha-1 of FYM was used. Total nitrogen ranged from 0.45 to 0.95 g kg-1 of soil, average for doses of both fertilizers, whereas total phosphorus content ranged from 0.26 to 0.48 g kg-1 of soil. The highest amylase activity was observed in the soil when FYM was used (0.48 ng starch g-1 l6 h-1) as compared to the soil where slurry was applied (0.41 g starch ug-1 16 h-1). No increase of amylase activity was observed when the doses of both fertilizers were the highest. A higher urease activity was noted when FYM was used than in the case of the soil manured with slurry.A decrease of urease activity was noted in the control samples (3.0 mg NH3 10 g-1 24 h-1), while the urease activity increased when the doses of both fertilizers were the highest. The highest activities were noted when 80 t ha-1 of FYM or slurry were used.

Effect of organic ( with Humidol Standard) and mineral (with NPK) fertilization on some physico-chemical and chemical properties of sandy soils in the LGOM region were studied.The experiment was founded with two factors and a sub-block method.Humidol Standard was intro- duced once, and minerał fertilisation each year. The studies showed that fertilisation with Humidol Standards inereased the amount of organie matter, improved fraction composition of humic com- pounds and physico-chemical properties of sandy soils. Fertilisation with Humidol Standard com- bined with NPK can be a safe agrotechnical treatment that improves soil fertility in a short period of time in the region of LGOM.

In order to compare the effect of organic and mineral fertilization of various soil types, long-term fertilization experiments frequently use indices, being a function of various parameters considered simultaneously; the content of organic carbon, microbiological parameters and soil enzymatic activity. The aim of the present research was to define soil fertility based on the values of Biochemical Soil Fertility Index (B). The index has been formulated based on the research results obtained: enzymatic activity, content of organic carbon and total nitrogen. The research material was sampled from topsoil of a many-year experiment which included varied organic and mineral fertilization, established on typical lessive soil. Soil samples were collected in 1998 from winter wheat stand, four times over the vegetation period. The following enzymes were determined: dehydrogenases, alkaline phosphatases, proteases and amylases. Additionally Corg and Ntotal and pH in 1 M KC.

A field experiment was conducted in central-eastern Poland in the years 1999-2003. It analyzed the effect of catch crop green fertilizers on soil humidity in a three-year-long crop vegetable rotation (white cabbage, onion, red beet). Oats, field pea and spring vetch cultivated in pure sowing and as mixtures were used as green fertilizers. The effect of green manures was compared with ploughed in farmland manure in the dose of 25 t·ha-1 and the control without any organic fertilization. White cabbage was grown in the first year after organic fertilization, onion – in the second and red beet – in the third.
