The official systematic soil testing system in the Czech Republic has practically 60 years duration – since 1961 is provided for needs of state administrative body and simultaneously for farmers. The extraction procedure Mehlich 3 is the official analytical method presently used (since 1999) in this soil testing system for the determination of available macronutrients (P, K, Mg, Ca). On the ground of uniformity, suitability and relatively cheap process of this analytical procedure, Mehlich 3 extractant can be used for a multiple-element extraction from soils, including determination available micronutrients (B, Cu, Zn, Mn, Fe). On the other hand Mehlich 3 extractant has some limits for right determination of available phosphorus content in carbonate soils (i.e. soils with pH value 7.2 and higher and simultaneously with content of available calcium 3500 and more mg kg -1 of soil). Extraction method Mehlich 3 used for determination of available phosphorus, usually doesn ́t indicate real phosphorus content in carbonate soils. There is content of available phosphorus more or less undervalued according to valid limits (criteria) for all soils. New, updated criteria of valuation of available phosphorus content in carbonate soils will be used for elimination of this incorrectness.

Harvest residues of field crops are important for matter cycling in the agroecosystem, especially when organic fertilizers are not applied in adequate amounts. The aim of this study was to assess the influence of increasing nitrogen doses and harvest residues (HR) on corn yield. The international stationary field trial (ISDV) has been established on a calcareous chernozem soil, at Rimski Šančevi, on Institute of Field and Vegetable Crops, Novi Sad. This paper review two-year average yields on corn hybrid NS 3022. The trial had six treatments, three with HR (0, 100, 200 kg N ha -1 ) and three without HR (0, 100, 200 kg N ha 1 ). The experiment was set up in three-crop rotation (corn, soybean, wheat). The average yield with and without HR treatments was 7.22 t ha -1 . The average yield obtained on treatments with HR was 7.64 t ha -1 , which was higher by 0.85 t ha -1 (12.52%) than the average yield on treatments without HR (6.79 t ha -1 ). The highest yield on treatments with HR was achieved with 100 kg N ha -1 a (8.44 t ha -1 ) while the highest yield on treatments without HR was obtained with 200 kg N ha -1 (8.56 t ha -1 ). On average, HR increased the yield of corn grain in the control treatment by 1.18 t ha -1 . To achieve good yields of corn grain, optimal nitrogen doses on treatments with HR should range from 100 kg N ha -1 to 200 kg N ha -1 , while on treatments without HR optimal doses of nitrogen should be closer to 200 kg N ha -1 .
田间作物的收获残余物对农业生态系统中的物质循环很重要，特别是在有机肥用量不足的情况下。本研究的目的是评价氮肥用量增加和收获残留物(HR)对玉米产量的影响。国际固定田间试验(ISDV)已在诺维萨德大田和蔬菜作物研究所的Rimski Šančevi的钙质黑钙土上建立起来。本文综述了玉米杂交种ns3022的两年平均产量。试验共设6个处理，3个处理施氮量(0、100、200 kg N hm -1)， 3个处理不施氮量(0、100、200 kg N hm -1)。试验采用玉米、大豆、小麦三作物轮作。经HR处理和不经HR处理的平均产量为7.22 t / h。有HR处理的平均产量为7.64 tha -1，比无HR处理的平均产量(6.79 tha -1)高出0.85 tha -1(12.52%)。施氮量为100 kg hm -1 a (8.44 t hm -1)的处理产量最高，不施氮量为200 kg hm -1 (8.56 t hm -1)的处理产量最高。对照处理的玉米产量平均增加1.18 t / h。为使玉米籽粒获得良好产量，施氮量为100 ~ 200 kg N ha -1，而不施氮量为200 kg N ha -1。

Soil microorganisms, which are usually found in plant rhizosphere, have a wide spectrum of beneficial effects on the promotion of plant growth. The most comprehensively studied bacteria with these effects belong to the Bacillus genus. In this study, seven Bacillus isolates from Medicago sativa rhizosphere soils were isolated. Plant growth promoting characteristics of these isolates, such as production of indole-3aceticacid, siderophores and hydrogen cyanide were tested. The induction of wheat (Triticum aestivum) and barley (Hordeum jubatum) seed germination was evaluated in vitro. Isolate BMG2 produced the highest indole-3-aceticacid of 24.89 μg/mL. The length of roots of barley increased up to 60%, while the length of shoots of barley increased 2.23 times afterapplying isolatesPAZE-6 and BMG1, respectively. In addition, isolates BMG1, BMG2 and PAZE-6 improved germination of both types of seeds and showed ability to produce useful substances such as siderophores and indole-3-acetic acid. Further, these isolates could be used in the production of liquid crop additives that can improve the total yield of cultivated plants, especially barley.

The paper presents the results of a three-year trial (2011-2013) on the variability of the yield of dry overhead biomass of the seeding grassland depending on the application of N fertilizer.Three grass-leguminous mixtures and one grass mixture has been researched (total of ten species of grass and leguminose) in the process of the biological phase of the reclamation of the technogenic soil, the type of Deposol. The research has been conducted on the Deposol at internal disposal area for overburden from Raskovac open pit in Stanari coal mine(Republic of Srpska, Bosnia and Herzegovina).The seeded grasslands stand for the significant driving force of pedogenetic processes in new soil reclamation. There are four treatments of doses of N fertilizers in application (N1 144, N2114, N3100 and N4130kg/ha). N fertilizer is used in basic and supplemented grassland nutrition. The application of N fertilizer in the seeded grassland has shown significant variation of dry biomass. The results have varied by years, different compositions and particular cuttings. In 2011 the N effect was lower in the first than in the second cutting. In 2012 and 2013 the N effect was better in the first cutting. The highest effect of N fertilizer is found with the TDS-3 mixture in every research year ( x 1 kg N = 36.32 kg in 2011, x 1 kg N = 97.67 kg in 2012 and x 1 kg N = 115.93 kg of biomass in 2013). The highest effect of 1 kg N on the biomass yield is calculated at TDS mixture at N3 treatment in the first cutting in 2013 (190.12). The lowest effect of 1 kg N on the biomass yield is calculated at the TDS-1 composition at treatment N3 in the first cutting in 2011 (10.00). The better effect is achieved with the smaller dose of N fertilizer. This is the starting point in any future standardization of fertilizers when fertilizing the seeded grasslands in the process of Deposol reclamation.
本文介绍了一项为期三年(2011-2013)的试验结果，该试验研究了播草草地干地上生物量产量随施氮量的变化。研究了三种草-豆科混合物和一种草-豆科混合物(共10种草和豆科糖)在技术土壤复垦过程中的生物阶段，即沉积物类型。对斯坦纳里煤矿(斯普斯卡共和国，波斯尼亚-黑塞哥维那)拉斯科瓦茨露天采场覆岩内部处置区的沉积物进行了研究。种子草地是新垦殖土壤成土过程的重要驱动力。施氮量有4个处理(n1144、N2114、N3100和n4130公斤/公顷)。草地基本营养和补充营养分别施用氮肥。播草草地施氮对干生物量有显著影响。结果随年份、不同的成分和特定的岩屑而变化。2011年，第一次的氮素效应低于第二次。2012年和2013年第一次扦插氮素效果较好。TDS-3混合肥料在各研究年度的氮肥效果最高(2011年x 1 kg N = 36.32 kg, 2012年x 1 kg N = 97.67 kg, 2013年x 1 kg N = 115.93 kg)。1 kg N对2013年第一次刈割时N3处理TDS混合液生物量产量的影响最大(190.12)。1 kg N对生物量产量的影响最低，以2011年第一次刈割时N3处理下TDS-1组成计算(10.00)。氮肥用量越小，效果越好。这是将来在Deposol复垦过程中对种子草原施肥时，任何肥料标准化的起点。

In this paper, the soil used for growing poplar and willow is explored. The physical and chemical characteristics of these soils are shown. The hydrological characteristics of the area where these soils are spreading, as well as the methods of humidification of these soils by flood and ground waters, are the basis for the successful cultivation of softwoods in the investigated areas. From the presented characteristics of the investigated soils and the studied hydrological conditions are defined soils suitable for growing poplar and soil for the cultivation of willow.

Losses of soil calciumdue to migration from Umbric Albeluvisols Abruptic soil meliorated by various doses of chalk were studied in column experimentwith 16 washings. It has been established that the dynamic of calcium leaching from soil limed with optimal dose (1) and increased dose (2) is of a similar nature. In both treatments in the first 5 and 3 washes, respectively, there was a sharp decrease in the amount of calcium in the soil as described by exponential model. Starting from 6 and 4 washes, respectively, stabilizationin Ca losses occurred. It was found that an increase in the chalk dose by 2.7 times increases the leaching of calcium by 4.8 times. It was concluded that an attempt to create in soil a certain reserve of available calcium for plants by increasing the dose of a finely ground ameliorant is ineffective because it increases unproductive losses of calcium. It has been suggested that in the soil there is a buffer system: exchangeable calcium ↔ calcium of soil solution, which even in the conditions of intensive wetting maintains the presence of a certain amount of water-soluble calcium.
