Arttırılmış Elementel Sülfür Dozlarının Kireçli Bir Toprağın pH Değerine Etkisi

Toprakların yüksek pH değeri kirecin etkisiyle; genellikle fosfor dahil olmak üzere birçok bitki besin elementlerinin alınabilirliğini sınırlamaktadır. Elementel kükürt (S) uygulamaları, toprak pH’sını düşürmek için kullanılan başlıca yöntemlerden bir tanesidir. S uygulamaları rizosferdeki pH değerini azaltmak için kullanılan ekonomik bir kaynak olmasına rağmen, önerilen S dozları toprak pH’sını düşürmede sıklıkla etkisiz kalmaktadır. Bu nedenle, yapılan çalışmada hem pratikte önerilen kükürt dozlarının hem de yoğun kükürt ilavesinin toprak pH' sı üzerindeki etkileri araştırılmıştır. Elementel kükürdün ağırlık esasına göre % 0-0.01-0.02-0.04-0.08-0.16-0.32 ve 0.64 oranlarındaki uygulamalarının toprak pH’sı üzerindeki etkisi inkübasyon çalışmasında, saksı denemeleri ile belirlenmiştir. Çalışmada kullanılan toprak örneği Konya, Selçuk Üniversitesi Ziraat Fakültesi Sarıcalar deneme alanından 0-30 cm derinlikten alınmıştır. Denemede kullanılan toprak örneği, hafif alkali (pH 7.97) reaksiyonlu, kireçli (%12.25), az tuzlu, düşük organik madde ve yarayışlı fosfor kapsamlıdır. Başlangıçta kükürt eklenmiş olan toprak örnekleri, saf su ile tarla kapasitesine getirilmiş ve 10 hafta boyunca 28 °C'de inkübasyona bırakılmıştır. İnkübasyon dönemi boyunca haftalık olarak pH ölçümleri yapılmış ve toprağı tarla kapasitesi su içeriğinde tutmak için düzenli olarak eksilen kadar saf su ilave edilmiştir. Tüm uygulamalar toprak pH’sında sınırlı bir azalmaya neden olurken, zaman içerisinde pH değerleri tekrar artma eğilimi göstermiştir.

Effect of Enhanced Elemental Sulphur Doses on pH Value of a Calcareous Soil

Due to the lime content, the high pH value of the soils usually can limit the availability of some plant nutrients including phosphorus. Elemental sulfur (S) applications are one of the leading methods used for lowering soil pH value. Although S application is an economic resource used for reducing pH value in the rhizosphere, recommended S doses are often ineffective in lowering soil pH value. For this reason, this study was carried out to look into the effects of both the recommended sulphur doses and the intense doses of sulphur additions on the soil pH value. The effect of different S application doses in weight percentages as 0-0.01-0.02-0.04-0.08-0.16-0.32 and0.64 % of elemental S, on soil pH was determined in the pot experiment. The soil sample was taken at 0-30 cm Sarıcalar Experimental area of Agricultural Faculty of Selcuk University in Konya. The soil sample used in the study has light alkaline pH value (7.97), calcareous (12.25%), low salty less salty, organic matter content and available phosphorus concentration. At first, S were added soil samples at the pot experiment, then after, water content was brought to field capacity using pure water and incubated at 28°C for the period of 10 weeks. Weekly, pH measurements were made throughout the incubation period and regular pure water additions were made to ensure that the soil steadily remains at the field capacity. All applications led to a decrease in soil pH values, while pH is inclined to increase again during the course of time in the pot experiments.
