The soil fertility was degraded as a result of unreasonable tillage, therefore the application of site-specific nutrient replacement is necessary. It is essential for the application of precision fertilization to know the location, extension, soil properties and nutrient-supply of the different soil types ofcultivated areas.We collected soil samples from 580 hectares of land in 2006. Soil samples were collected from every 5 ha in 30 and 60 cm depths during Spring from 20.05.2006 to 12.06.2006 and again in Autumn from 09.19.2006 to 02.10.2006. Soil samples were analysed at the Department of Agricultural Chemistry and Soil Science of DE-ATC.The two examined soils are slightly calcareous, weakly saline, poor in zinc. The calcareous chernozem soil is slightly acid, the content of humus, nitrogen, phosphorus and potassium is medium in this soil. The meadow chernozem soil is slightly alkaline, and properly supplied with humus and potassium, and middling supplied with nitrogen and phosphorus. The meadow chernozem soil is more heterogenous in soil plasticity, lime, saline, nitrogen phosphorus and potassium content and less heterogenous in pH and zinc content than the calcareous chernozem soil.Standard deviation of measured values in pH, soil plasticity, humus and nitrogen content significantly differ between the examined soil types. The soil plasticity, pH, humus, nitrogen and zinc content significantly differ among calcareous chernozem soil and meadow chernozem soil, but the difference in phosphorus content can be statistically proven only in case of Spring soil sampling.

The research is based on the results of studying the effect of solid organic fertilizers based on cattle manure (cattle) of various storage periods on the supply of productive moisture and the chemical composition of meadow-chernozem soil. The studies were carried out at LLC RUSKOM-Agro, Omsk region in 2017-2018. The application of organic fertilizers significantly increases the content of nitrate nitrogen (from very low to very high levels), mobile phosphorus and potassium. In the first year of aftereffect, manure doses continue to have a significant impact on the nutrient regime of the soil. Moisture reserves before sowing were characterized as good (133-154 mm) without significant changes when applying manure.

The N, P and K effects of mineral fertilisers were examined in a long-term fertilisation experiment set up on chernozem soil with forest residues. The data from 20 experiments on winter wheat and 24 on maize were evaluated as a function of the year, the forecrop and the soil nutrient supplies.Of the two plant species, N effects were found to be greater for winter wheat. When sown after maize, the N responses of both wheat and maize were almost 1 t ha −1 greater than when winter wheat was the forecrop. The positive effect of phosphorus was only significant in winter wheat, while that of potassium was not significant for either species.In a wheat-wheat sequence, N fertiliser alone was only effective in wet years. In winter wheat, no phosphorus effects could be detected in any year without N fertilisation. In years with extreme weather conditions, P effects were only significant when wheat was grown after cereals.In dry years nitrogen only had a significant effect on the yield of maize after wheat if it was combined with phosphorus and potassium. In years with average or above-average rainfall maize was able to extract sufficient phosphorus for its development even from soils with poor P supplies; yield increases were limited by other factors.

A szójaoltás hatékonyságát és az oltóanyagtörzsek gazdanövény specificitását vizsgáltuk csernozjom talajon, szántóföldi körülmények között. A szóját (Glycine max L., Kurca) 80 kg vetőmag/5×1011 CFU arányban oltottuk. Az oltást a vegetációs periódus folyamán mikroelem tápoldattal egészítettük ki. Az eredményeket kezelésenként 5×1 folyóméter növény- és talajminta vizsgálata alapján értékeltük. A mikroszimbionta baktériumtörzsek összehasonlító jellemzését BOX-PCR módszerrel végeztük el. Megállapítottuk, hogy a vizsgált kontrollnövényeken nem volt gümőképződés. A szója magoltása sikeres volt. Az oltóanyagtörzsek infekciós- és N-kötő aktivitása megfelelő volt, növényenként átlagosan 6–7 összetett, aktív gümő képződött. Az oltás hatására a növények száraztömege 25%-kal nőtt. A kiegészítő mikroelem tápoldat nem növelte szignifikánsan a növények száraztömegét és virágszámát. Az oltóanyagban lévő törzsek közül csak egy volt képes hatékony szimbiózist kialakítani a szójával, ami a gazdanövény és mikroszimbionta közötti kapcsolat nagyfokú specificitására utal. Ezt a PCR vizsgálat eredményei is alátámasztották.

A tenyészedényes kísérletünket a DE AGTC MÉK Agrokémiai és Talajtani Intézet tenyészházában állítottuk be 2010. május 27-én. A kísérletben Debrecen-Látókép környékéről származó mészlepedékes csernozjom vályogtalajt alkalmaztunk, amely az alábbi jellemzőkkel rendelkezett: KA: 37,5; leiszapolható rész: 51%; pH(KCl): 5,5; pH(H2O): 6,6; Hu%: 2,8; AL-P2O5: 140 mg·kg-1; AL-K2O: 316,3 mg·kg-1. Az adatok alapján a kísérleti talaj gyengén savanyú, vályog kötöttségű, közepes nitrogén- és foszfor-, valamint jó kálium-ellátottsággal rendelkezett. A kísérletben kontroll-, műtrágya-, valamint szalmakezelést alkalmaztunk, melyeket bizonyos kombinációkban három különböző baktériumkészítménnyel (Bactofil A, EM-1, Microbion UNC) egészítettünk ki. A kísérletet három ismétlésben véletlenblokk elrendezésben állítottuk be. A tesztnövény angolperje (Lolium perenneL.) volt. A kísérlet kezdetétől számított 8. héten a talaj-, valamint a növényminták begyűjtésére került sor. Meghatároztuk a növényminták száraztömegét, a növény foszfor- és káliumtartalmát, valamint a talajminták nitrát-, valamint AL-oldható foszfor- és káliumtartalmát. Eredményeink alapján főbb megállapításaink a következők: – Az angolperje száraztömegét a műtrágyakezelés szignifikánsan növelte. A hatás a tápelem-ellátottság javulásával magyarázható. – A növény foszforkoncentrációja a műtrágyázás következtében csökkent, amelyet a hígulási effektussal magyarázhatunk. – A növény káliumkoncentrációját a műtrágya-, valamint a műtrágya+baktériumtrágya kezelések szignifikánsan serkentették. – A talaj nitráttartalma szignifikánsan növekedett a műtrágyakezelés kivételével minden kezelésben. – A talaj AL-P2O5-tartalma az NPK-műtrágyázás és az EM-1 kezelés következtében statisztikailag igazolható mértékben megnövekedett, míg az AL-K2O-tartalom kizárólag a szalmakezelés hatására nőtt. A baktériumkészítmények önmagukban alkalmazva általában nem eredményeztek jelentős változást a vizsgált paraméterekben, azonban a készítmények szerves/ásványi anyagokkal kombinált adagolása esetében különböző mértékben befolyásolták a vizsgált mutatókat.

Effects of supplemental dietary lysine and methionine in a Groundnut Cake (GNC) based diets on meat and bone characteristics of broiler chickens were investigated. In a completely randomized design, a total of 168 one - day – old Arbor acre broiler chicks were randomly allocated to seven dietary treatments each in triplicate of eight birds per replicate. The Seven starter and finishers’ diets were: GNC based diets without any amino acid (lysine or methionine) supplementation (T1); GNC diet + 0.2% lysine (T2); GNC diet + 0.4% lysine (T3); GNC diet + 0.2% methionine (T4); GNC diet + 0.4% methionine (T5); GNC diet + 0.2 lysine and 0.2% methionine (T6) and GNC diet + 0.4% lysine and 0.4% methionine (T7). Experimental diets and water were offered to birds ad libitum in an experiment lasting six-week. At day 42, two birds per replicate were slaughtered, meat and bone characteristics determined. There were significant variations (P<0.05) in the crude protein (%) and ether extract (%), pH1 and pH2 of meat. Thiobarbituric acid reactive substances composition of meat at days 0, 5, and 10 were similar (P<0.05) and were not affected by dietary amino acid supplementation. Tibiotarsal index (mg/mm) of bone (22.10, 27.25, 33.35, 31.40, 28.70, 31.45 and 29.75 for broilers on T1, T2, T3, T4, T5, T6 and T7, respectively) were increased significantly (P<0.05) by amino acid supplementation. Significantly differences (P<0.05) were observed in the calcium, phosphorus and potassium (%) contents of broilers’ bone across treatments. Supplemental lysine and both lysine and methionine improved meat quality and bone development of broiler chickens in this study.

Long-term observations of the drained soil of peat-podzolic-gley light loam on ancient alluvial sands state on the example of the meliorative object "Tinky-2" showed that under the influence of agricultural use in the soil, the organic matter mineralization processes are accelerated. During the drainage process, the soil evolutionarily suffered the following changes: the peat layer was compacted, humified and mineralized, which was a reason of the transformation them into the humus horizon. Based on the monitoring studies results it was established that during 21 intensive use years the peat layer thickness was decreased by 74.5% and amounted to 5.51 inch, which in the following 20 years was decreased to a layer of 1.18 inch, and for another 14 years it became a homogeneous humus horizon containing difficulty identifiable plant remains. For half a century, the bulk density increased by 6 times and the total moisture capacity of the soil decreased by 3.6 times. Other indicators were changed significantly. So, the ash content by 2016 increased from 11.2% to 52.7%. It was a reason of the plough-layer decreasing and it mixes with the mineral sand horizon during plowing. It should also be noted that the total nitrogen content in the soil decreased by 1.13%, and total carbon by 15.3% from 1982 to 2016. The dynamics of changes in the soil acidity, phosphorus and potassium content is associated with the introduction of calcareous, organic and mineral fertilizers in the 1980s. The unsystematic exploitation of such soils leads to decrease in the agricultural products productivity and increase in energy costs. When planning these soils usage in agricultural production, it is necessary to develop and implement modern melioration technologies and techniques aimed to increase soil fertility.
