Summary: In 1988 year researched precipitation reactions (pH)
with dry deposition on three locations in Križevci, one location in
Koprivnica and one location in Varaždin. Resultes of precipitation
reactions (pH) with other meteorological data are shown in table 2.
The lowest pH of 3.23 was determined on march 18,1988, and highest pH
7.88 on july 4, 1988 year.
Percipitation amount in 1-2 days varied from 0.1 to 80.1 mm.Yearly
precipitation pH were calculated for the researched locations:
Križevci 5.36, Koprivnica 0.57 and Varaždin 6.44.
It was computed significant correlation between precipitation reaction
(pH) in Križevci and Koprivnica.
Between amount of daily precipitation in mm and precipitation reaction
(pH) were computed next correlations and regressions:
-Križevci R=0.53** and regression
y=6.397-0.08155x+0.001053x2
-Koprivnica R=0.29* and regression
y=6.08-0.04957x+0.000729x2
-Varaždin R=0.32* and regression
y=6.776-0.024024x+0.00024019x2 (See graphs 2,3)
According to computed regressions, daily precipitation over 11.4 mm in
Križevci and over 11.5 mm in Koprivnica have on anaverage reaction (pH)
lower than 5.6.
Between variations of average daily air temperatures and precipitation
reaction for some months were computed correlation sand regressions which
show table 3 and graph 4. It was determined that stronger cyclones and cold
air fronts which come from west,north-west and north Europe to our areas
bring, as a rule, acid precipitation.
Keywords: precipitation reaction (pH), precipitation amount, acid precipitation, average daily air temperature, correlations, regressions

Summary: Natural meadows of north-west Croatia according to the
statistical data from 1981 cover 193.732 ha or 24.3% agricultural surface.
They mainly belon to these associations:
- sedges (as.Caricetum tricostato-vulpinae)
- bullpates (as.Deschampsietum caespitosae)
- cynosurus (as.Bromo-Cynosuretum cristati) and
- button grass (as.Arrhenatheretum elatioris).
They are used as two-cut meadows. The characteristics of their habitats
mutually much differ. Thus big differences have been established in the
mechanical soil composition expressed in the percentage of soil particles
less than <0.01 mm and the percentage of particles less than <0.002 mm in
the pedological profile at the depth of 0-15 cm.

Summary: Parallel researches of soil and lawn properties in
ecosystem of natural lowland meadows were performed in period from 1955 to
1970 year on 38 unfertilized variants of fertilisation trials and specially
on 23 unfertilized meadows.
Meadows belong to next associations: Caricetum tricostato-vulpinae,
Deschampsietum caespitosae, Bromo-Cynosuretum cristati and Arrhenatheretum
elatioris.
Soil reaction (pH) in H2O and n-KCl was determined in electometric way with
glass electorde in suspension 1:2.5.
Botanical composition was determined by method Klapp et al. modified by
Šoštarić-Pisačić and Kovačević. There were determined percentages of meadow
plant groups: grasses (Poaceae), grasslike plants (Cyperaceae, Juncaceae),
legumes (Fabaceae) and forbs (Asteraceae, Plantaginaceae, Apiaceae,
Rubiaceae, Ranunculaceae and other families).

Summary: Colchicum autumnale L. (meadow saffron) is one of
mostpoisionous plants in meadow, so it belongs to absolute meadowweed.
During 1990. and 1991. biology, ecology and control ofColchicum
autumnale were researched in Križevci region.
We have investigated the beginning and duration ofphenophasas, way of
propagation, seed properties, number ofplants in turf and so on.
In the context of ecological investigations chemical andmechanical soil
properties of C. cutumnale habitat have beenresearched. Correlations and
regresions beetwen soil propertiesand the number of C. autumnale were
determined.
It has been also researched phytocenological properties ofthe C.
autumnale habitat., including plants wich acompany C.autumnale most
frequently and in biggest mass. On the basis ofthe botanical composition
humidity of the habitat has beenestimated.
In oder to control C. autumnale, trials witr 8 differentherbicide
treatments and with fertilized and unfertilized controlwere set. It was
investigated influence of treatments on dclineof Colchicum autumnale,
reduciton of flowering and reduction ofdevelopment in next year. The
influence of treatments on hayyield and hay quality was also investigated.
Keywords: Colchicum autumnale L., absolute meadow weed, biology, ecology, control.

Title: Plant cover and habitats in the Kalnik-Križevci region,
- Authors:
- Ivanek, Vilim (17225)
Language: hrvatski
Summary: The paper presents the results of simultaneous field and
laboratory phytocoenological and pedological investigations of major plant
associations of indigenous and anthropogenic ecological systems in the
Kalnik-Križevci region. Results of pedological analyses of the soils of
plant associations are presented in 14 tables.
These results of simultaneous investigations of plant cover and site
properties point to the conclusion that the floral composition of plant
associations in ecological systems, particularly forests and meadows,
results from the mutual adaptation of plant species and their genetic
response to the relief, geological substratum, climate and microclimate,
pedological soil properties, as well as anthropogenic and other biogenic
influences.

Title: Genetic evaluation of soil classification

- Ivanek, Vilim (17225)
Language: hrvatski
Summary: A genetic method of research and soil classification has
been evaluated on the basis of pedological maps for the Republic of
Croatia, literature and soil properties research of pedological profiles,
in particular on the basis of Pleistocene Aeolian substrate in the Križevci
area.
It was established that this method is inappropriate for the present-day
requirements of agriculture, forestry, ecology and environmental protection
on the basis of the following reasons:
- it uses a method of taking average soil samples from subjectively
evaluated horizons that do not give representative results of pedological
analyses and a clear dynamics of pedological processes in a soil profile,
- it does not provide basis for establishing anthropogenetic influence on
soil, erosion and protection of soil and plant cover,...

Title: Pedological soil properties in ecosystem of lowland
forests in the Križevci and Vrbovec area
- Authors:
- Ivanek, Vilim (17225)
Language: hrvatski
Summary: The paper presents the results of soil properties analysis
in pedological profiles down to the depth of 150 cm in relation to
floristic tree composition in the forests of black alder (Alnus glutinosa),
European ash (Fraxinus angustifolia), British oak (Quercus robur) and their
transitions.
Ecosystem is mainly developed on marsh and pseudogley soils that originated
from Holocene alluvium close to lower courses of the rivers Lonja,
Glogovnica, Česma and their tributary streams.
The moistest soils are in the forests of black alder (Alnus glutinosa).
Excessive moistening exchanges with land reclamation during summer all the
year round on the soils of European ash (Fraxinus angustifolia). These
exchanges of soil moisture with the appearance of ground vegetation
condition clay development in surface soil horizons and initial development
of rugged microrelief.....

Title: Inappropriateness of floristic photography of plant cover
by Braun-Blanquet method in ecological studies
- Authors:
- Ivanek, Vilim (17225)
Language: hrvatski
Summary: Former studies of plant associations and their mapping in
Croatia were done on the principles of floristic system of the
Zuerich-Montpellier school. In floristic photography a method of a combined
estimate of individual numbers of a single plant and its cover was applied
whose author is Braun-Blanquet.
The obtained results of such floristic photography do not present a basis
for deeper ecological, agricultural and other studies, for these floristic
photographs do not constitute sufficiently distinctive quantitative
relationships among individual species in plant associations and they can
not be compared in more detail to habitat properties....

region

Summary: Forests of sessile oak and sweet chestnut
(Querco-Castanetum croaticum H-t 1938) used to be developed on many
hillocks up to moderately high hills in the Kalnik piedmont region at
130-600 m above sea level. The forests have been developing since
Pleistocene, after the end of the last ice age, on thick decarbonated
extremely acid aeolian geological substratum of luvisol, the properties of
which are shown in Table 1.
Decarbonation of wind driven atmospheric dust was carried out by biogenic
factors and processes by means of water drops trapped in tree tops and
leaves.
Centuires long spreading of anthropogenic ecological systems, especially
plough fields, vineyards and ruderal sites, shifted these forests, as well
as other acidophilic forests, to sites unsuitable for agriculture, on which
extremely acid luvisol was preserved from erosion.
