متن کاملTranscriptional response of nitrifying communities to wetting of dry soil.
The first rainfall following a severe dry period provides an abrupt water potential change that is both an acute physiological stress and a defined stimulus for the reawakening of soil microbial communities. We followed the responses of indigenous communities of ammonia-oxidizing bacteria, ammonia-oxidizing archaea, and nitrite-oxidizing bacteria to the addition of water to laboratory incubatio...

Response of Maize to Phosphorus Fertilization on Hydromorphic Soil of Bosnian Posavina Area
INTRODUCTION Acid reaction and nutritional unbalances, mainly low level of plant available phosphorus (P) as well as unfavorable physical properties are limiting factor of soil fertility in Bosnia (Okiljević et al., 1997; Resulović and Čustović, 2002). It is estimated that about 25% of agricultural land of Bosnia and Herzegovina are pseudogley or similar soils (Marković and Supić, 2003). P as a...
متن کاملMechanisms for soil moisture effects on activity of nitrifying bacteria.
Moisture may limit microbial activity in a wide range of environments including salt water, food, wood, biofilms, and soils. Low water availability can inhibit microbial activity by lowering intracellular water potential and thus reducing hydration and activity of enzymes. In solid matrices, low water content may also reduce microbial activity by restricting substrate supply. As pores within so...
