FARKLI ORGANİK MATERYAL UYGULAMALARININ TOPRAK AGREGATLARI ÜZERİNE ETKİSİ

Year 2008, Volume: 21 Issue: 2, 213 - 222, 01.12.2008

Abstract

Araştırmada, değişik kökene sahip üç adet organik materyalin toprağın agregat büyüklük dağılımı ve dayanıklılığı üzerine etkileri araştırılmıştır. Bu amaçla, Akdeniz Üniversitesi Kampüsündeki Korkuluk Serisinin 0-25 cm derinliğinden bozulmuş toprak örneği olarak alınan Kırmızı Akdeniz Toprakları (Lithic Rhodoxeralf) kullanılmıştır. Çalışma sera koşullarında saksı denemesi olarak yürütülmüştür. Organik materyallerden işlenmiş tavuk gübresi ve çöp kompostu 1250, 2500 ve 5000 kg ha-1, işlenmiş leonardit 100, 200 ve 400 kg ha-1 olmak üzere üç farklı dozda uygulanmıştır. Yedi aylık bir inkübasyon periyodu sonunda elde edilen bulgulara göre, uygulamaların toprağın agregat büyüklük dağılımı ve dayanıklılığı üzerine etkisi değişik agregat boyutlarında farklı düzeylerde gerçekleşmiştir. Agregat büyüklük dağılımı üzerine etki bakımından işlenmiş tavuk gübresi 8-4 mm boyutlu agregatlarda % 5, 1-0,5 mm boyutlu agregatlarda % 1 düzeyinde, çöp kompostu 2-1 mm boyutlu agregatlarda % 1 ve 0,5-0,25 mm boyutlu agregatlarda ise % 5 düzeyinde önemlilik göstermiştir. İşlenmiş leonardit uygulaması 0,5-0,25 ve 0,25-0,050 mm boyutlu agregatlarda % 5 düzeyinde etkili olmuştur. Agregat dayanıklılığına etki bakımından, işlenmiş tavuk gübresi 8-4 mm boyutlu agregatlarda % 0,1, 4-2 mm boyutlu agregatlarda % 5 düzeyinde, çöp kompostu 2-1 ve 1-0,5 mm boyutlu agregatlarda % 1 düzeyinde, işlenmiş leonardit ise 8-4 mm boyutlu agregatlarda % 0,1 ve 4-2 mm boyutlu agregatlarda % 5 düzeyinde önemli olmuştur. Çalışmada, organik materyallerin toprağa düzenli uygulanması ile agregat büyüklük dağılımında ve agregat dayanıklılığında önemli değişimlerin elde edilebileceği düşünülmektedir

The Effects of Differently Originated Organic Materials Applications on Soil Aggregates

Year 2008, Volume: 21 Issue: 2, 213 - 222, 01.12.2008

Abstract

In this research, effects of organic material applications on size distribution and stability of soil aggregates have been studied. For this purpose, soil was collected from the 0-25 cm layer of Mediterranean Red Soils (Lithic Rhodoxeralf) at the Akdeniz University campus. The study was carried out under the greenhouse conditions as a pot experiment. Organic materials were applied to soil in three different doses, as processed chicken manure and municipal waste compost of 1250, 2500 and 5000 kg ha-1 and as processed leonardite of 100, 200 and 400 kg ha-1. Results obtained after a seven-month incubation period showed that effects of different organic materials on soil aggregate formation and aggregate stability in soil were different in terms of influence and levels for different aggregate sizes. The effect of processed chicken manure on aggregate formation was significant at level of % 5 and % 1 for 8-4 and 1-0.5 mm and municipal waste compost was significant at level % 1 and % 5 for 2-1 and 0.5-0.25 mm aggregate size, respectively. On the other hand the effect of processed leonardite on aggregate formation was significant at level of % 5 for 0.5-0.25 and 0.25-0.050 mm aggregate size. The effect of processed chicken manure on aggregate stability was significant at level of % 0.1 and % 5 in 8-4 and 4-2 mm, respectively and municipal waste compost was significant at level of % 1 in 2-1 and 1-0.5 mm and processed leonardite was significant at level % 0.1 and % 5 in 8-4 and 4-2 mm aggregate size, respectively. It is concluded that the size distribution and stability of aggregates in soils can be change by the periodically use of organic materials.
