Nitrogen fertilizer plays an important role in corn cultivation in terms of both economic and environmental aspects nitrogen fertilizer positively affects corn yield and the soil organic carbon level, but it also has negative environmental effects through nitrogen-related emissions from soil (eg, n2o, nox, no3. Lack of both experience in cultivation and knowledge of best fertilizer management gave ipi grounds for carrying out farm field trials the results of the experiment conducted at two locations varying in phosphorus (p), potassium (k) and magnesium (mg) levels are presented in the paper, studying the effect of different potash. Although overall chemical fertilizer use has grown steadily in nepal in the past two decades, much of that growth has occurred in the terai agroecological belt while use has stagnated in the determinants of chemical fertilizer use in nepal: insights based on price responsiveness and income effects ifpri discussion paper. The intention of the present study was to contribute to the development of waste- based compound fertilizer products by investigating (i) n use efficiency and (ii) p and k fertilization effects of various waste resources since n turned out to be the growth-limiting factor, in the present paper we focus on n fertilization effects of. Tivity this study was conducted to evaluate the effect of paper sludge and dairy manure on biomass production of shrub willow (salix dasyclados sv1) and to determine the impacts of these amendments on soil chemical properties treatments included urea, dairy manure and paper sludge separately and. Previous studies reporting that paper mill sludges, ap- plied on different soil types and under various climatic conditions, significantly increased the yield of winter cab- table 3 effects of annual and biennial paper mill sludges and n fertilizer application on corn grain yields, specific gravity and n uptake. Content and heavy metal concentration of applying de-inked paper mill sludge ( dpms) over the period 1991 to 1993 in the first year, during decomposition of the dpms, n immobilization occurred resulting in loss of cereal yield (p 005) at low rates of n fertilizer approximately 40 kg extra n fertilizer/ha was required per.

Organic, inorganic, and liquid fertilizers were utilized in this study to investigate their effect on nitrate concentrations and lettuce growth the results of this pot experiment the total nitrogen concentration in the filtrate of the plants and soils passed through filter papers (whatman no 42, kent, uk) was. A pot experiment was conducted under greenhouse to determine the crop performance and the effects of compost on soil animals and microorganisms in two lowland rice soils the two soils were: (a) organic lowland soil that had been applied with carabao manure for about 12 years, and (b) conventional lowland soil that.
Effect of compost and inorganic fertilizers on yield and quality of tomato was investigated in field experiment carried out on silt loam soil at nuclear institute of food and agriculture (nifa), peshawar during summer 2016 the experiment was arranged in a randomized complete block design (rcbd) with. Abstractthe aim of the study was to assess the effects of organic fertilization on selected chemical properties of the soil and the activity of dehydrogenase and β- glucosidase in the soil of forest nursery the main goal was to evaluate the role of organic fertilizers in carbon storage in the forest nursery soil.
Paper sludges are known as lignin-rich organic material that resist against mineralization  and therefore contribute to increase the soil organic matter content [1, 8, 12] paper sludges may also have a long-lasting effect on soil structure  and fertility than some animal manure which generally induce. The fertilizer used to promote growth of the wheat crop was found to be the largest single process contributing to environmental impact metrics (red bar in fig 2), for the authors declare that the data supporting the findings of this study are available within the paper and its supplementary information files.
Salinity and soil nutrient deficiencies are the main factors reducing plant productivity in arid and semiarid areas among the essential elements, nitrogen is usually the most growth limiting plant nutrient in saline or non-saline soils a pot experiment was carried out in the greenhouse to evaluate the influence of composted. Night3-5 being new introduction, no detailed work has been done on clarysage in indian context but, high demands in pharmaceutical and cosmetic industries effect of organic manures and chemical fertilizers on the performance of a newly introduced aromatic crop clarysage (salvia sclarea linn) in the uttarakhand. The overall objective of this research was to evaluate the short- and intermediate- term effects of repeatedly amending sandy soil with paper mill residuals agriculture carbon/analysis conservation of natural resources fertilizers industrial waste paper plants silicon dioxide soil water/analysis water supply.
Eip-agri focus group fertiliser efficiency in horticulture, mini- paper fertiliser planning 2 this paper will include a brief outline of the process of developing a fertiliser recommendation system the effects of previous history on the starting n supply and enable the option of more closely.
To obtain a high tuber yield of early crop potato good conditions for plant growth must be ensured potato has a relatively shallow root system and requires significant nutrient inputs to maintain tuber productivity and quality the paper presents the results of the research on the effect of complex fertilizers type npk mgs with. In two recent papers (see here and here) the trio argues that the net effect of synthetic nitrogen use is to reduce soil's organic matter content why because, they posit, nitrogen fertilizer stimulates soil microbes, which feast on organic matter over time, the impact of this enhanced microbial appetite. Effect test of industrial organic manure on the physical growth and yield performance of bean in bugesera district environment key words: organic manure, earth boost, colta bean variety, bean fertilization i introduction a widespread view holds that in their paper, benoit et al (2003) said particularly harmful.
