Bu araştırma, Atatürk Üniversitesi Erzurum Çiftliği topraklarında
katyon değişim kapasitesi ve değişebilir katyonların agregat
stabilitesi ile ili.$kisini ortaya koymak için yapılmıştır. Bu gaye ile
önceden tesbit edilmiş olan toprak tiplerini temsil edecek surette yüzeydenden (0-30 cm) onüç adet toprak örneği almmlJtır.
Ara.jtırma sonuçlarına göre; topraklann reaksiyonu 6,8-8,1,
organik madde mulıtevası :yo 0,8-43,4, değişebilir kalsiyum 11,6-40,0
me./lOO gr., değişebilir mağnezyum 2,4-14,4 me./lOO gr., katyon
değişim kapasitesi 16,3-64,2 me./100 gr. ve agrega!>yon değeri de
% 35,7 - 92,5 arasında değişmektedir.
Ara.jtırma konusu topraklarda değişebilir kalsiyum, değişebilir
mağnezyum, değişebilir toplam kalsiyum ve mağnezyum ve katyon değişim
kapasitesi ile agregasyon arasında %5 ihtimalte sırasile pozitif önemli
ilişkiler (r=0,5770; 0,5805; 0,6010; 0,6317) elde edilmiştir.
SUMMARY
This investigation has been conducted
to detect the relationsips between
both cation exchange capacity and
exchangeable cations and aggregation
stability of the soils on the Farm of
Atatürk Üniversity in Erzurum. The
area investigated extends from the base
of Palandöken Mountains in the south
to the canai öf Karasu in the north.
lt has young alluvial material carried
by the Paşalar and Kırkdeğirmenler
streams.
For this reason , thirteen soil
samples so that to characterize the area
investigated have been taken from the
topsoil (0-12 in.)
According to the results obtained,
the vaIues of pH, organic matter,
exchangeabIe cakium, exchangeable
magnesium, total exchangeable calcium
and magne sium,cation exchange
capacity and aggregation of the soils
have been found between 6.8-8. i;
0.8-43.4 %; 11.6-40.0 mejlOO gr.;
2.4-14.4 me./100 gr.; 16.Ü-54,4 me./
100 gr; 16.3-64.2 me./100 gr. and
35.7-92.5 % , respectively.
Between both the values of the
exchangeable calcium and exchangeable
magnesiuın and aggregation of
the soils, significant positive correlation
coefficients (r = +0.5770 and
+ 0.5808, respectively) have been obtained
at the level of 5 %'
Positive correlation coefficients
(r=+0.601O and + 0.6316, respectively)
at the level of 5% have been
found between both total excahangeable
cakium and magnesium and cation
exchange capacity and aggregation of
the soil samples.
These show that there are significent
relationships between those properties
and aggregation of the soils
investigated.
