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 کاملSoil microbial responses to nitrogen addition in arid ecosystems
The N cycle of arid ecosystems is influenced by low soil organic matter, high soil pH, and extremes in water potential and temperature that lead to open canopies and development of biological soil crusts (biocrusts). We investigated the effects of N amendment on soil microbial dynamics in a Larrea tridentata-Ambrosia dumosa shrubland site in southern Nevada USA. Sites were fertilized with a NO3...
متن کاملSoil Biochemical Responses to Nitrogen Addition in a Bamboo Forest
Many vital ecosystem processes take place in the soils and are greatly affected by the increasing active nitrogen (N) deposition observed globally. Nitrogen deposition generally affects ecosystem processes through the changes in soil biochemical properties such as soil nutrient availability, microbial properties and enzyme activities. In order to evaluate the soil biochemical responses to eleva...
متن کاملResponses of enzymatic activities within soil aggregates to 9-year nitrogen and water addition in a semi-arid grassland
Soil microorganisms secrete enzymes used to metabolize carbon (C), nitrogen (N), and phosphorus (P) from the organic materials typically found in soil. Because of the connection with the active microbial biomass, soil enzyme activities can be used to investigate microbial nutrient cycling including the microbial response to environmental changes, transformation rates and to address the location...
