Influence of mineral and organic fertilizers on yield and nitrogen efficiency of winter wheat
The aim of this study was to evaluate the long-term (16-years) nitrogenefficiency after the application of organic and mineral fertilizers at two sitesLukavec (S1) and Suchdol (S2) with different soil and climatic conditions in theCzech Republic (Central Europe) and to determine grain yield and nitrogen contentwith regard to the requirements of protein content for baking quality of wheat.After ...
متن کاملEffect of Organic and Inorganic Sources of Nitrogen on Maize Yield,N Uptake and Soil Fertility
mineral and organic N sources (farmyard manure) on maize yield, N uptake and soil fertility was assisted in the field experiment carriedout on silty clay loam soil at new developmental farm of the university of agriculture, Peshawar Pakistanduring 2014. Combined dose of N provided from all sources was applied @150 kg ha-1. There were four replications and 6 treatmentsi.e., (T1) control, (T2) 15...
متن کاملThe changes in microbial biomass C and N in long-term field experiments
Microbial biomass nitrogen and carbon were studied in long-term field experiments with continuous cultivation of silage maize and with crop rotation. a positive effect of organic fertilizers on the microbial biomass nitrogen and the carbon content in soil was observed. Statistically significant effect of organic fertilizers on the higher content of microbial biomass C and n was established in t...
متن کاملNitrogen and Carbon Isotope Composition of Organic Fertilizers
Synthetic (e.g. urea) and organic fertilizers (e.g. compost) differed markedly in N isotope composition and the greater the difference between organic and synthetic fertilizer the more robust will be the differentiation of crops and vegetable grown under different farming systems. The objective of this study was to compare nitrogen and carbon isotope composition of organic fertilizers and manur...
