A single dose of 10, 25 and 50% (weight percentage) of the soil collected from sugar-processing plant was added to loose sand and brown soil. A four year - pot experiment was set where the following were cultivated, in turn: corn, buckwheat, spring wheat and corn. It was observed that the content of phenolic acids in soil grew proportionally to the dose of soil introduced and it was positively correlated with the contents of C-org, N-org, available P, K and Mg forms, floatable forms and sorption capacity, as well as the plant yield and its nitrogen and magnesium contents. However, the content of phenolic acids in brown soil did not show a linear dependence on the sediment dose, it correlated negatively with the amount of C fraction most susceptible to biological oxidation and with microbiological respiration activity, yet positively with the concentration of potassium available in soils, yield and its nitrogen content.

Research carried out in the Western Beskid Mountains (Silesian Beskid, Beskid Mały and Beskid Żywiecki Mts) attempted to characterise the enzymatic activity of soils in various forest sites and associations. Twenty study plots were established to represent a range of sites and associations of the lower and upper mountain forest zones. The soils were analysed for the activity of dehydrogenases and phosphatases. Enzymatic activity was compared in the top soil (humus-accumulating mineral horizons) and soil columns of 1 dm² cross-section and 50 cm in depth. It was found that the activity of the studied enzymes, especially dehydrogenases, varied between the soils, suggesting that soils from different types of sites or associations have different microbiological activities. The results of the research contribute to the development of microbiological activity patterns for near-natural mountain forest sites and associations. Based on such patterns it would be possible to assess deterioration changes occurring in forest soils.

Badane gleby wykazują znaczne zróżnicowanie "właściwości chemicznych, które jest spowodowane warunkami siedliskowymi i związaną z tym zawartością materii organicznej. Zachodzący w odwodnionych glebach hydrogenicznych proces murszenia doprowadził do ubytku węgla organicznego i akumulacji azotu w wierzchnich poziomach. W wyniku tego stosunek C:N wynosił w murszach średnio 15.1, a był szerszy w torfach (18.4), Najniższym stosunkiem C:N charakteryzowały się gleby murszaste (średnio 9.7). Stosunek strat prażenia (LOI) do węgla organicznego w badanych glebach waha się w szerokich granicach od 1.3 do 2.94. Gleby murszaste (o zawartości 3-10% materii organicznej) cechują się wyższym stosunkiem LOI:C org, (średnio 2.26) w porównaniu z murszami (średnio 1.86), co jest prawdopodobnie spowodowane większą zawartością uwodnionych związków żelaza. Badane gleby charakteryzowały się średnią do bardzo wysokiej zawartością azotu mineralnego po inkubacji. Stosunek N-N03 do N-NH4 byl wyższy od 1, co wskazuje na przewagę mikrobiologicznych przemian tlenowych. Jedynie silnie uwodnione gleby z jednego obiektu charakteryzowały się niską zawartością azotu po inkubacji. Potwierdza to hamujący wpływ wysokiego uwilgotnienia gleb (>70% obj.) na mineralizację organicznych połączeń azotu. Badane gleby charakteryzują się bardzo niską zawartością potasu, magnezu i miedzi. Zawartość fosforu jest bardzo zróżnicowana. Nie stwierdzono też zależności korelacyjnych między zawartością fosforu a zawartością materii organicznej, wapnia i żelaza. Gleby murszaste powinny być okresowo wapnowane wapnem magnezowym oraz powinno się stosować nawożenie organiczne.

Forage legumes are used to enhance soil fertility of the agroecosystem. Understanding their effect on the agroecosystem during their growing period is essential. The objective of this field study was to evaluate annual clovers intercropping and earthworm activity on the growth of weeds. The field experiment was carried out during the 2006–2007 growing seasons at the research farm of the Seed and Plant Improvement Institute, Karaj (Iran) involving various mixed cropping ratios of berseem clover (Trifolium alexandrinum L., B) and Persian clover (Trifolium resupinatum L., P) (B : P = 1 : 0, 3 : 1, 1 : 1, 1 : 3) with and without earthworm Pheretima sp. inoculation. Nitrogen content of plants and weeds as well as biomass was measured. Forage yield was higher in 2006 than 2007 but had similar response to cropping systems and earthworm inoculation. Total forage yield was highest in mixed cropping system (MCS). While in the first cut, the berseem sole crop (SC) tended to greatly suppress the growth of weeds, in the second cut Persian clover sole crop further suppressed weeds. The greater total crop biomass had an even higher weed suppression. Earthworm activity did not affect cut 1 but increased forage and weed biomass yield in cut 2. However in cut 1, berseem tended to greatly suppress the growth of weeds, which may be explained by the greater nitrogen accumulation in monocultures and intercrops, Persian clover in cut 2 had greater suppression on weed biomass production. Nitrogen accumulation of crops and weed increased under earthworm activity in the second cut.

The field experiment was conducted with four tillage and three nutrient management practices at Agronomy field unit, University of Agricultural Sciences, GKVK, Bangalore, Karnataka, India. The results of the study indicated that, higher groundnut pod yield (1307 and 1282 kg ha-1) and haulm yield (2733 and 2889 kg ha-1) was recorded with mechanical tillage + two intercultivations and integrated application of 50% organics and 50% inorganics, respectively as compared to rest of the treatments. Further, the same treatments noticed higher availability of N, P2O5 and K2O in soil after harvest of groundnut, but greater improvement in soil organic carbon content was observed with conventional tillage + one intercultivation (0.62%) as compared to rest of the tillage practices. The maximum net returns and benefit-cost ratio was recorded with mechanical tillage + two intercultivations (Rs. 11,287 ha-1 and 1.75, respectively) and integrated application of 50% organics + 50% inorganics (Rs. 10,462 ha-1 and 1.69, respectively). However, interaction effect of tillage and nutrient management practices were not influenced significantly on soil fertility and productivity of groundnut under rainfed farming system.

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.
