IMPLICATIONS OF MOBILE-BASED INFORMATION SYSTEMS IN CONTAMINATED SOILS CHARACTERIZATION | Author : Cioru?a Bogdan-Vasile, Coman Mirela | Abstract | Full Text | Abstract :There is a wide range of Environmental Information Systems (EISs), both desktop and mobile
platforms, with usability in industry and applied ecological studies. Of these, EISs for mobile devices
have begun to be increasingly used in the current activity of those concerned with soil protection and
agriculture management. According to the utilization impact of the mobile EISs in environmental
protection, we introduce a new platform system, as an electronic field-observation agenda. It is
configured and created with App Inventor software, for mobile devices under Android OS. The new
application, that we created, came as an efficient approach in data and field-observation acquisition.
The application was made using the tools offered by App Inventor 2.0 integrated development
environment. It turned out to be extremely convenient to use, without the need for programming
knowledge or special mobile devices, other than mobile phones owned. The SoilMonitor application,
by its particular implication in environmental impact assessment (in contaminated soils
management), requires complex interdisciplinary knowledge as well as profound technical
information developed in the environment-informatics complex context. The field sheets completed
with the help of the newly created application are of real use and can be the basis for creating an
extremely complex environmental database. We try to demonstrate that the innovative technology
associated with mobile apps, focusing on soil pollution monitoring and assessment can be an
alternative to the classical monitoring approach, where the classic work-agenda is still not absent
from the field. |
| GEOGRAPHIC INFORMATION SYSTEMS IN THE EVALUATION OF THE AGRICULTURAL POTENTIAL IN THE BANAT MOUNTAINS | Author : Magureanu Margareta, Copacean Loredana, Simon Mihai, Cojocariu Luminita | Abstract | Full Text | Abstract :The aim of this paper is to assess the agricultural potential of the mountainous area in
southwestern Banat, by methods and geospatial materials that can complete or replace analog
cartographic materials, especially in areas where they are lacking. As a case study, two
administrative-territorial units from the Banat Mountains were selected: Ciclova Româna and Sasca
Montana. The fact that the study area overlaps over a large altitudinal range, between 123 - 1131 m,
determines the variability of environmental conditions and is implicitly reflected in the use of land.
The scientific information and geospatial data used in the research were processed in the GIS
environment. The map of the land use for the analyzed area was obtained by processing the Corine
Land Cover database, 2018 edition. Thus, it was found that, in the analyzed area, the forest areas
occupy more than half of the territory, the pastures are found on approx. 17 % of the surface, and the
arable lands, in lower percentages, on small areas, in the areas with low altitude. Land resources are
of particular importance given the rural nature of the area and specific traditions. |
| THE INFLUENCE OF SOIL FERTILITY REGARDING THE FAVORABILITY OF RAPESEED CROPS IN THE CRI?URILOR PLAIN | Author : Lovasz Andra, Borza Ioana, Brejea Radu, ?erban Eugenia, Sabau Nicu Cornel | Abstract | Full Text | Abstract :The production capacity of the land or its productive potential, are both valued by soil
fertility, the influence on the physiological requirements of the plants and other environmental
factors. The productive potential of the Ecological Homogenous Territory (EHT), together with their
pretendability for different uses and crops are evaluated using the land quality and productivity
assessment (bonitation).
Given the climatic conditions, the agricultural potential and the socio-economic aspects of
Romania, rapeseed (Brassica napus L.) is one of the most profitable crops. The objective of this work
is to assess the influence of soil fertility regarding the favorability of rapesees and on the economic
value of agricultural land, under the conditions of the Cri?urilor Plain. The rapeseed qualifys in the
second class of favoritism (81 points) for EHT occupied by Pachic Phaeozem (EHT - PP) and in the
fourth grade for EHT occupied by Haplic Luvisol (EHT - HL) with 65 points.
The production increases of the main crops, conducted by EHT - PP compared with EHT -
HP are between 17.5 % for wheat and barley, and 43.1 % for sugar beet. Economic efficiency of the
agricultural holding, for both EHT’S, it involves increasing the water supply of the soil by irrigation
and in case of EHT - HP improvement of the humus content in soil through ameliorative fertilization.
Out of the four crops used in the area, rapeseed brings the highest net income, which is 3843 lei/ha
(784 euro/ha), for EHT - HL and 5355 lei/ha (1093 euro/ha), for EHT – PP. Under almost similar
environmental conditions, the economic value of the land increases from 13422 euros/ha, for EHT-
HL to 17698 euros/ha for EHT-PP. |
| LONG-TERM TILLAGE EFFECTS ON CROP YIELD IN THE TRANS-TISZA REGION OF HUNGARY | Author : Bichi Abdulwahab Abdulrazaq, Zsembeli József, Nagy Attila | Abstract | Full Text | Abstract :This research was conducted to test the effect of tillage techniques Conventional Tillage (CT)
and Reduced (RT) on the yield of three crops; Corn, Sunflower and Winter Wheat; in a long-term
tillage experiment. The objective was to determine the effect of the tillage methods on yield of the
various crops. Data of the long-term tillage experiments were collected from Karcag Research
Institute of the University of Debrecen. The data were then analysed using independent samples t-test
on SPSS.
The CT plots on average produced the highest amount of yield for all the three tested crops.
Although the mean difference in all the tested crops where not large. For sunflower, CT recorded an
average yield of (2858.67 kg/ha) compared to RT’s (2505.42 kg/ha). For winter wheat, CT produced
an average yield of (5689 kg/ha) compared to (5529.9 kg/ha) for RT. And for corn, CT recorded an
average yield of (7629.56 kg/ha) compared to (6991.78 kg/ha) for RT.
The results obtained from the independent samples t-test for all three crops showed that there
was no significant difference in crop yield between the two tillage techniques i.e. CT and RT. A
significance level of 0.005 was chosen for the test and the p value for winter wheat, Sun flower and
corn were; p=0.831; p=0.264; p=0.647
This research concluded that yield is not significantly affected by tillage technique for this
region (Trans-Tisza Hungary) and for this soil type (meadow chernozem soils). It is recommended
that reduced tillage may be preferred in this region because of its soil and water conservation
potential as yield performance can be overlooked. However, improved weed and soil compaction
control should be practiced along with it to improve yield. |
| USAGE OF FERMENTED CHICKEN MANURE AS A BIOFERTILIZER IN AN APPLE ORCHARD | Author : Tóth Florence, Tamás János, Csihon Ádám, Nagy Péter Tamás | Abstract | Full Text | Abstract :Effects of fermented chicken manure on soil nutrient availability, leaf nutrient status and fruit
quality parameters were studied in an apple plantation from Eastern Hungary. Beside control, three
fermented chicken manure products (BIO-FER Natur Extra, Nitro vit and 7-9-7) were used in a field
experiment trial at the Horticultural Experimental Farm of University of Debrecen in 2020. In this
trial, soil and leaf analysis were made to check the effects of applied treatments on the nutrient supply
of the soil and the nutrient status of the leaves. Beside soil and leaf analysis, yield and some fruit
quality parameters were investigated. The products were applied at the beginning of April in 2020.
Each treatment consisted of 5 trees.
Soil pH has slightly decreased during the trial. The organic carbon content of the soil has not
significantly changed during the experiment. Chicken manure treatments could not affect
considerably the soil P, K, Mg, Mn, Cu and Zn content compared to the control. All applied
treatments increased the N content of leaves compared to the control, but the effect was not
significant. Leaf P content was the same in all treatments, while the leaf K content was slightly higher
where chicken products were used. Leaf Ca and Mg were not affected significantly by the treatments
compared to the control.
The usage of chicken manure increased yield, fruit weight and fruit flesh hardness compared
to the control, but significant effect was observed only in certain treatments. Moreover, all applied
treatments decreased the Brix value of apples compared to the control. |
| GENETIC DIVERSITY ANALYSIS BY SDS-PAGE AND SCORING MIXOGRAPH DOUGH OF ALGERIAN DURUM WHEAT (TRITICUM TURGIDUM L. VAR. DURUM) | Author : Boukhalfoun Leila, Kirouani Abderrezzak, Taghouti Mona, Henkrar Fatima | Abstract | Full Text | Abstract :Durum wheat is used predominantly for pasta and couscous but the use of durum
wheat for breads is also common in Mediterranean countries. High molecular weight (HMW-GS) and
Low molecular weight glutenin subunits (LMW-GS) play an important role in determining the bread
quality of durum wheat. In this study we used twenty one local and introduced durum wheat varieties
cultivated in Algeria, that were grown in the same environmental conditions. These cultivars were
evaluated for their variability in several traits related to technological qualities. The present study
showed the presence of significant differences within our genetic resources for several traits. Indeed,
by SDS-PAGE, a low diversity was shown among genotypes used at Glu-A1 locus, confirming the
dominance of (c) allele, however Glu-B1 present a high diversity with the superiority of (b) and (e)
alleles. Based on mixing time (MT) and bandwidth at peak dough resistance (BWPDR) values,
Mixograph test indicated a mean score of 6.5 suggesting a good bread making ability of Algerian
durum wheat. In fact, Ofanto, Mexicali75, Vitron, Chen’s and Saoura held the top of the rank scoring
a value of 8, followed by Hedba03, Simeto and Marzak (used as check) showing a score of 7.5. This is
due to the presence in their flours a high gluten strength according to the test of SDS sedimentation.
These results are very motivating to be used in local durum wheat improvement program. |
