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...

Large amounts of uranium, radium and radium products are redistributed throughout the environment owing to the use of phosphate fertilizers. Potential radiological impacts resulting from direct exposure, inhalation and ingestion of foods grown with fertilizers are discussed. This paper describes a simple method to measure exhalation rate of 222RN from phosphate fertilizers, clay and potatoes in...

Controlledrelease fertilizers (CRFs) offer an excellent option to improve nutrients uptake by plants and reduce the environmental hazards due to excess release of chemicals. Polymer-coated fertilizers, compared to the other types of CRF, are by far the most intensively researched topic because of their great characteristics. Polymercoated fertilizers, which are less sensitive to the soil and en...

Over the past years highly effective phytopreparations with antibacterial activity have been created in Russia. Macleaya x kevensis Turill, which is a hybrid between heart-shaped ( cordata ) and small-fruited microcarpa ), can serve as raw material for their production. To provide pharmaceutical industry this type of conditions North Caucasian branch VILAR, plantations crop research being carri...

Leaching and nitrous oxide (N2O) emissions can represent substantial nitrogen (N) losses from chemical fertilizers, slow-release fertilizers (SRFs) mitigate these effects. Thus, biochar be an alternative agronomic environmental point of view to synthesize SRFs due its physicochemical characteristics. We investigated the effect nitrogenous organomineral (OMF-N) formulated based on activated N by...

An experiment was conducted to find out the effect of INM on vegetative growth, flowering and fruiting of Andrographis paniculata. The experiment was followed in a randomized block design with 8 treatments. The different treatments were T1no treatment, T2vermicompost, T3-biofertilizers, T4-chemical fertilizers, T5biofertilizers + vermicompost, T6biofertilizers + chemical fertilizers, T7chemical...
