Summary: The humus-rich soil mixture was irradiated with
gamma-raydosesranging from 1 to 64 kGy in panoramic cobalt-60
source.Chemical and microbiological analyses were made of irradiated
andnon-irradiated soil in order to determinethe influence ofirradiation.
Data about changes of the nitric and ammoniacnitrogen in water extract werw
compared as well as total nitrogenlevel in dry matter. On the basis of the
changes observed,possible effects of the use of gamma irradiation in
sterilizationof soil mixture for agricultural plant growth have
beendiscussed. potential value of this method of sterilization in
theprevention of fungal diseases of young plants has been stressed.The feed
effects are to be observed as changes of relationbetween the quality of
nitrogen and the feed effect of organicmatter from the destroyed
microorganisms.

Summary: In holobiosis of root stock and scion, the stock gives a
systemof roots with a specific and genetically conditioned arrangementof
main and overgrowing roots in soil, depending on ecologicaland edaphic
conditions of producing area. The roots system playsan important mechanical
and phyisiological role for a fruit-tree.Therefore, the root stock affects
rankness and through it, thebeginning and duration of particular
phenophases of vegetation,as well as many other changes in above ground
portions of afruit-tree, e.g. nourishment, proportion of essential
mineralelements for nutrition etc., then altogether affectingfruitfulness
and fruit quality. The work included research of theimpact of root stock
Prunus cerasus and Prunus mahaleb onvegetation development, chemical
composition of leaves and fruitquality of marasca cherry.
The research was conducted in 1981 and 1982 at the CompositeOrganisation of
Associated Labour - Agricultural Combine "Zadar",the Basic Organisation of
Associated labour "Promet" Benkovac,and at the manufacturing facility
"Gajine" in Ceranj.

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

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.
