regional soils
Abstract.
The article scientifically presents the results of studies of the absorptive capacity and composition of the
absorbed bases of soils in the sierozem and desert regions. Also, in this article presents the amount of absorbed bases
in the soils of the Madaniyat massiv of Konimekh district of the Navoi region, and the amount of exchangeable cations
(Ca
+
, Mg
++
, K
+
, Na
+
) in the soil absorbing complex. The current state of sandy-desert, gray-brown and gray-brown-
meadow irrigated soils is described.
Key words:
Serozem soils, sandy-desert, gray-brown and gray-brown-meadow irrigated soils, absorption complex,
cations, soil fertility.

Tuproq paydo bo‘lishi jarayonlarida,
xususan, davriy sug‘orishlar ta’sirida tuproqlar
shakllanishida turli mineral jinslar, mineral va
organik moddalarning to‘xtovsiz maydalanishi
va parchalanishi natijasida hosil bo‘lgan aralash
zarralar dispers sistemani tashkil etib, unda
o‘lchami 1µ (mikron)dan kichik, kolloid xossasiga
ega bo‘lgan barcha zarrachalar yig‘indisi, ya’ni
tuproqning singdirish kompleksi vujudga keladi [2].
Bu jarayonda tuproqning singdirish sig‘imi
(singdirish kompleksi) va singdirilgan kationlar
tarkibi ham, organik modda singari ularning
ko‘plab xossalarini, tuproqlarni alohida o‘ziga
xos xususiyatlari va unumdorligini belgilab, uning
kimyoviy, fizik-kimyoviy, agrokimyoviy hamda bir
qator fizik xossalariga ta’sir ko‘rsatadi. Xususan,
tuproq singdirish qobiliyati faol ta’siri o‘simliklar
va mikroorganizmlar uchun oziqa elementlarining
to‘planishini ta’minlagani holda tuproq oziqa
rejimini tartibga soladi, asosiysi tuproq reaksiyasi,
uning buferlik darajasi hamda suv-fizik xossalarini
tartibga solishda ishtirok etadi [6].

mexanik va mineralogik tarkibi, gumuslashganlik
