TOPRAĞA ORGANİK MATERYAL İLAVESİNİN TOPRAĞIN ORGANİK MADDESİ, AGREGAT STABİLİTESİ VE GEÇİRGENLİĞİ ÜZERİNE ETKİLERİ

Abstract

OZET Bu arastirmanin amaci, topraga organik materyal (ahir gubresi ve bugday samani) ilave edilmesinin topragin organik maddesi, agregat stabilitesi ve gecirgenJigi uzerine etkilerini ve aralarindaki iliskileri belirlemektir. Arastirmada, Igdir ovasindan (Bati Igdir Ovasi) alinan dort adet yuzey (0-10 cm) toprak ornegi uzerinde calisilmistir. Topraklara ahir gubresi (<2mm) ve bugday samani (<lmm) 5 duzeyde uygulanmis ve topraklar tarta kapasiteleri civarinda 45 gunluk inkiibasyona tabi tutulmuslardir. Arastirma sonuclarina gore, organik materyallerin ilave edilen duzeylerine bagli olarak, topraklarin organik maddesi, agregat stabilitesi ve gecirgenlik degerleri artmis ve her toprakta bu ozellikler arasinda pozitif iliskiler tespit edilmistir. EFFECTS OF ADDENG ORGANIC MATERIAL INTO THE SOILS ON ORGANIC MATTER, AGGREGATE STABILITY AND PERMEABILITY OF SOILS SUMMARY The purpose ofthis research w as to determine the effects of addirion of organic materials (manure and wheat straw) into the soils on their organic matter, aggregate stability andpermeabiiity values. In this research four surface (0-10 cm) soil samples laken from the Igdir district (Westlgdtr district) was used. In this experiment, manure (<2mm) and wheat straw (<lmm) at five levels of 0; 05; I; 2 and 4 % on the owen dry weight basis were added, as three replications, into four soil samples and these admixtures were incubated for forty-five days at nearly field capacity in laboratory conditions. At the end of incubation period, organic matter, aggregate stability an permeability of admbctures were determined respectively by Smith-Weldon, wet siemng and constend head permeameter. in statistical evaluation of the experimental results the "Simple Correlation" analysis vva.i applied. This research showed that as the additions of organic material increased the organic matter, the aggregate stability and the permeability of the soil increased Highly significant relationships were obtained between above-mentioned soil properties.
