    Summary: Aluminium tolerance of 83 genotypes from Croatia and YugoslavTriticum aestivum germplasm was evaluated in nutrient solutionshaving Al3+ activities of 0, 12.5 and 25 ŠM. Relative root lenght(25 ŠM Al3+/0 Al) of various genotypes ranged from 2 to 97% (fromvery sensitive to tolerant to Al). No genotype with Al toleranceclose to that of very tolerant cultivar Atlas-66 was found. Soil,climatic, fertilization, and liming effects that wheat plantsgiving seeds for the nutrient solution Al-tolerance sreening hadbeen subjected to during their growth cycle did not influence theAl-tolerance ranking. Significant correlation was found betweensreening wheat for Al tolerance in nutrient solutions and inacid Pseudogley soil amended with five rates of limestone ingreehouse experiment. seed protein concentration wassignificantly related to the Al-tolerance ranking (r2=0.962).Such a significant correlation was not obtained in a case ofrheological and other quality characteristics of seeds.Al-tolerant wheat genotypes identified in this study will be usedin breeding for improved Al tolerance.

    Summary: Agricultural production of lettuce often includes fertilizationwith excessive amounts of nitrogen in order to achieve very highyields. Overfertilization with nitrogen results in an increase ofnitrate content in lettuce thus posing potential danger for humanhealth (methemoglobinemia). The investigation was carried out toelucidate an influence of fertilization on nitrate content andlettuce yield. Identical experiments with five nitrogen levels(0-320 kg/ha) were set up in two glasshouses (Bjelovar andĐurđevac). Fertilizing with high nitrogen levels resulted in anicrease of nitrate content in lettuce during growth period, butno statistically significant differences were observed in yield.This research shwed that high yields of lettuce having relativelylow nitrate content in leaves may be achieved by reduced nitrogenfertilization.

    Summary: The pot experiment was estabilished to evaluate influence of mudon dry matter yield and nutrient uptake by mais and soya, as wellas residual action. Mud was mixed with soil at 10,20,40 and 80 gper pot. In the first year of experiment only the increasing ofPb acumulation in soil, mais and soya was occured. Other heavymetals Zn, Cu, Mn, Cd and Cr didn't show any changes in soil orplant tissue. At mais experiment, the negative influence of drymatter acumulation while at soya experiment positiv influencerespectivly to mud doses was occured. Pb uptake was greather bysoya although its transport into seed was poor. Withphysiological maturuty of mais the Pb concentrations wasincreased while at soya was decreased. Residual mud influence onyield wsn't observed and Pb concentration was reduced to normalrange of cultivated soil.

    Summary: This paper contain results on reasurche of amount of microelements and some heavy metals in cultivated and subcultivated stratum of different typs of soil in some gricultural areas of Croatia. Research on soil pollution with heavy metals are carried out under the program "Control of Soil Fertility in function of wholesome food production"as well as soil fertility control on the account of plant nutrition capacity on individual farms. Chemical characteristics of soil in average and individual samples were performed, but results regarding to those that influence mobility and adsorption of heavy metals in to the soil. The extraction of microelements and heavy metals were performed with 0.1 or 1.0 M HCl, depending on soil reaction and with AAAC-EDTA. In some samples the total content was measured by spectrometric atomic apsorption (AAS). The results of chemical analysis indicate that contents of all heavy metals vary depending upon the type of soil but the highest results do not surpass the permit limit.

    Summary: This work is part of the study "Economic potentials of the Solinska Zagora karst fields" and involves investigations of the plant nutrient capacity of the soil with the aim of making use of the arable parts of the mentioned fields and preventing contamination of River Jadro source water. Fluctuation of certain cations and anions in the Jadro source water was monitored. Soil reaction in the Mućko polje is of low acid to neutral reaction, in Dugopolje mainly acid and in Konjsko polje of neutral reaction. The soil humus content in all locations is low (average 2.15%), and nitrogen content varies from 0.10 to 0.27% (average 0.18%) Physiolgically active phosphorus content ranges in very wide values, and in average value is 7.89 mg P2O5/100 g tla, while content of physiologically active potassium is relatively high, in average 21 mg K2O/100 g soil. Soil content of physiolocically active magnesium is very high on all locations, and in average is 16,2 mg Mg/100 g soil. In the Jadro source water samples, ph, E.C., and concentrations of NH4-N, NO3-N, Na+, Ca2+, Mg2+, Cl-, K+, PO4-P and SO4- fluctuate during the year but generally do not exceed the maximum tolerated concentrations for drinking water.

    Summary: Fertilizatiopn is good measure as long as it increases deficient nutrient levels to the optimal ones. Unfortunetly, in the efforts for higher fertilizer rates may often have detrimental effects not only on the plant but also on the three esential environment factors-soil, water and air. Aimed at determining the optimal fertilization for high chicory yields in our agroecological conditions, and as low as possible accumulation of harmful substances in the plant, investigations were carried out with the folloving fertilizer rates: 0, 50, 150 and 200 kg N/ha; 0 and 100 kg P2O5/ha; and 0, 100 and 200 kg K2O/ha. Investigation results pointed to the following: Soil analyses showed that nutrient availability during the growing season was higher that towards its end and that , at the end of vegetation, all values dropped to a desirable level, except in the case of the fertilizer rate at 200 kg N/ha, where the values for NO3-n (6.10 to 6.53 mg/100 g soil) and NH4-N (2.05 mg/100g soil) were still too high. Application of 50 to 200 kg/ha of nitrogen led to significantincrease of nitrates in the plant relative to the control treatment. At the end of vegetation , however, all nitrate contretations in the plant (693 to 975 mg NO3/kg green mass) dropped below the tolerated values for vegetables (1500 to 2500 mg NO3/kg green mass) according to European regulations and FAO standards. Regardless of fertilization, the yields achieved (2.1 to 2.6 kg/m2) are higher than those cited in literature; however, without significant differences relative to control.

    Summary: Water samples from wells, torrential streams, canals and the River Jadro source were taken in the period from November 1992 to July 1993 at the Mućko and Konjsko Polje locations. Samples of surface water were also taken from arable parts in karst field were it had accumulated during the rainy season. Water samples were analyzed for K, Ca, Mg, Na, NH4-N, NO3-N, PO4-P, SO4 and Cl. Physical parameters of water reaction (pH) and electro-condutivity (EC) were also measured. Influence of the karst field soil management on the chemical composition of the waters in the Jadro source watershed region was investigated with special reference to the concentrations of NO3-N, NH4-N, PO4-P and K. As all waters of the region except well water, have periodical caracter, they are to a large extent dependent on the exchange of dry and wet seasons. Considerably higher concentrations of NH4-Nand NO3-N ions were recorded in the spring -winter period than in summer. The average concentration of ions in all investigated waters varies in dependence on the moistening regime. The NH4-N ion concentration is considerably higher in well water and the canel water from Mućko and Konjsko Poljethan in drinking water and that from the Jadro source. Concentrations of NO3-N in the investigation period did not exceed the MTC (maximum tolerated concentration) values for drinking water. An increased concentration of PO4-P ions (0.52 mg/l PO4-P9 was recorded only in the Mućko Polje water from torrential stream Radača.

    Summary: Agricultural production of vegetables often includesfertilization with excessive amounts of nitrogen in order toachieve very high yields. Overfertilization with nitrogen resultsin an increase of nitrate content in leafy vegetables thus posingpotential danger for human health (methemoglobinemija). In 1985we have started a great number of reserches about the influenceof different levels of nitrogen on leafy vegetables andaccumulation of nitrates in their leaves. the first investigationwas carried out with lettuce in a glasshouse in Zadar. Theexperiment continued five nitrogen levels (0-400 kg/ha). Thisresearch showed that high yields (5.32-5.99 kg/m2) of lettucewith low nitrate content in leaves may be achieved by reducednitrogen levels in case of good supply of the substrate (3 me/LNO3). In 1989, identical glasshouses (locations Bjelovar andĐurđevac). Fertilizing with high nitrogen nitrogen levelsresultetd in an increase of nitrate content in lettuce duringgrowth period, but without statistically significant differencesin yield. At harvest nitrate content dropped within the range ofconcentrations considered safe for human consumption by FAOstandards (Ćustić, 1991). Investigations on head chichory hasbeen started in 1991 including various nitrogen levels (0-200 kgN/ha), on Faculty trial station. One year investiagation resultsshow statistically significant increase of nitrate although allvalues (639-975 mgNO3/kg) are still below the FAO standards forthe leafy vegetables. In every variants yields are higher(2.1-2.6 kg/m2) compared with literature datas (1.5-2.0 kg/m2).Taking into consideration Croatian agroekological conditions canbe concluded that we will achieve high yields if a soil issupplied with 0.2-0.25% N and 2.5 mg NO3/100 g of soil. Resultsof scientific researches mentioned above shows that leafyvegetables produced in Croatia satisfy the most rigorous marketcriterions.

    Summary: Zinc is an essential biogenic element for living organisms(plants, animals and humans) and plays an importan role inenzymatic processes. Living organisms need zinc in small amounts.From the ecological aspect, zinc is classified in the group ofheavy metals such as Pb, Hg, Cd, T and V. However, yincindisputably belongs to that group of heavy metals which for nowdos not pose the threat of contaminating the soil andenvironment. We cite several research controls of soil fertilityand test results: 1) The total zinc content in the soil cannot beused as an index for the level of soil contamination norcan simple limit limits be estabilished for this purpose.2) The zinc content in plant material is certainly the bestindex for determining the degree of environmentalcontamination (soil, water, air). 3) The zinc content in plantsvarious according to plant type, phase of development, partanalyzed, as well as numerous factors which influence the accessof zinc to a plant (pH, geologic base and mechanical system,percentage of organic materials, soil content of P, Ca, Cu, Fe,Mn). 4) Significantly more reliable limiting values in theassessment of soil for the production of so'called "wholesomefood" are those obtained as integral functions of plantproduction. 5) Increased zinc concentrations in the soil affectthe increased accumulation of zinc in plant tissue, which in thiscase have a depressive effect, and thus a toxic effect on thegrowth and development of plants. Only in suchagricultural-ecological situations can we speak of the limits forthe amounts of zinc posing a hazard in terms of the contaminationof soil and plants. 6) Possible problems regarding thecontamination of the environment with solid and liquid industrialwastes, waste mud, waste from zinc mines etc.should be discussed independently of the agricultural ecosystemsand the production of healthful wholesome food. On the basis ofthe material presented, it is demonstrated that in ouragricultural-ecologic situation the problem of excess zinc doesnot occur. Instead there exists zinc deficiency - latentdeficiences in plant food, which requires greater attention inthe future.

    Summary: In field tests on vertic hypoglej soil near Zagreb, five doses(0,2,4,6, and 8 t-hectare) of urban mud were tested with pilotequpment for cleaning waste urban water in comparision withFarmyard manure. The mud consisted of 31% organic materials;1,14% N, 0,89% P2O5, 0,6% K2O, 0.925% Ca, 0.62% Mg, 219, 190, 90,2100, 560, 0.024 and 0.19 mg-kg Mn, Zn, Cu, Fe, Pb, Hg and Cd.The mud was applied on time in 1985. For five years, the yieldsof the cultivated crops was monitored as well as the macronutrients, micro nutrients and heavy metals in the soil and theplant material. In the first year, in addition to the mud 1/2standard NPK was applied in relation to the standard NPKfertilizer. The yields were reduced by up to 15% on the variantsof fertilizer with 2 and 4 t/hectare of mud. The amounts of mudof 6 to 8 t/hectare were sufficient to replace 1/2 NPK fertilizerfor corn. The manure had a similar effect on yield and greateryields were realized 2 and 3 years after application. Later,extended effects of the mud or the manure were not noted on cropyields. The application of mud did not result in significantchanges in the content of the heavy metals (Pb, Cr, Cd, Hg) inthe soil and plant materials. In the test row mud was used from alagoon so that results should be assessed with reserve.
