Effect 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 کاملOrganic and inorganic nitrogen amendments to soil as nematode suppressants.
Inorganic fertilizers containing ammoniacal nitrogen or formulations releasing this form of N in the soil are most effective for suppressing nematode populations. Anhydrous ammonia has been shown to reduce soil populations of Tylenchorhynchus claytoni, Helicotylenchus dihystera, and Heterodera glycines. The rates required to obtain significant suppression of nematode populations are generally i...
متن کاملDetermination of the mean age of menopause and it's distribution terms of known variables in Kerman
This research is a cross _ sectional and descriptive study for determining of the mean age of menopause and related factors in Kerman province. The sample included 2000 of Kerman families which chosen by clustering method, and the women of 40_60 years were studied. The women who had not become menopause physiologically were omitted. So the sample size decreased to 224(102 urban, 122 rural). ...
متن کاملMetabolism of Labeled Organic Nitrogen in Soil: Regulation by Inorganic Nitrogen
Regulation of organic N metabolism by inorganic N availability was investigated in short-term laboratory incubations of soil. A C-, N-labeled organic N substrate was produced by growing Pseudomonas stutzeri in labeled media and isolating a cytoplasmic fraction. This was added to soils that had been preincubated with glucose or glucose plus NHJ to induce conditions of N deficiency or sufficiency...
متن کاملInfluences of a calcium gradient on soil inorganic nitrogen in the Adirondack Mountains, New York.
Studies of the long-term impacts of acidic deposition in Europe and North America have prompted growing interest in understanding the dynamics linking the nitrogen (N) and calcium (Ca) cycles in forested watersheds. While it has been shown that increasing concentrations of nitrate (NO3-) through atmospheric deposition or through nitrification can increase Ca loss, the reciprocal effects of Ca o...
