Microbial Biomass C and N and Activity of Enzymes in Soil under Winter Wheat Grown in Different Crop Management Systems
نویسندگان
چکیده
Microbial and biochemical analyses of soil under winter wheat in a field trial with various cultivation systems (organic, conventional and monoculture) were performed during 3 growing seasons: 2001, 2002 and 2003. The activities of the tested enzymes (dehydrogenase and phosphatases) and microbial biomass C and N contents in the monoculture soil were generally significantly lower than those in the soil from the organic and conventional–short rotation systems, indicating that substantial disturbances may occur in the microbial activity of the monoculture soil.

Crop management effect on chemical and biological properties of soil
This study was aimed at evaluating the effect of crop rotation and various tillage systems onthe chemical and biological properties of soil in the years 2013-2015. The first order factorincluded cropping systems: a) crop rotation (pea – winter wheat – spring wheat) and b)monoculture of winter wheat, whereas the second order factor were tillage systems:1) conventional (CT), 2) reduced (RT) and 3...
متن کاملInfluence of catch crop on soil properties and yield of spring barley
Biomass of legumes grown as catch crops improves soil properties and thus soil conditions for following crops. The aim of this study was to evaluate the effect of field pea (Pisum sativum L.) grown as a catch crop and used for green manure on soil properties and yielding of spring barley (Hordeum vulgare L.). Field experiments were conducted in 2008-2011 in the randomized block design with ...
متن کاملTurnover and fate of 15N-labelled cattle slurry ammonium-N applied in the autumn to winter wheat
The fate of 15NH4-N labelled cattle slurry applied before sowing in September of a winter wheat crop was studied on a loamy sand soil. The aim was to quantify immobilization of slurry 4 into microbial biomass, the speed at which nitrate derived from the slurry NH4-N was transported down the soil profile, and the utilization of slurry 4 by the winter wheat crop. Cattle slurry was applied at a ra...

This research was conducted to evaluate the trend of cadmium accumulation in wheat tissue and cultivated soil affected conventional cropping systems and different growth stage via split plot experiment based on randomized complete block design with three replications during 2014-2015 seasonal year. The main factor included two cropping systems (wheat-rice, fallow-wheat) and growth stage at thre...

Effects of six tillage practices on some soil microbiological properties and crop yields were evaluated for a clay soil (Typic Haploxererts) under semi-arid Mediterranean conditions in a three year study (2006-2009). The experiment was designed as a completely randomized-block with three replications. Treatments were: conventional tillage with residue incorporated (CT1), conventional tillage wi...
