Chemical phosphatic fertilizer

The research on the structure of the phytoplankton community in relation to the physicalchemical parameters of seawater needs to be carried out to see indicators of fertility and availability of natural food in the waters that will be used as a marine aquaculture location. To find out the relationship between physico-chemical parameters and phytoplankton abundance, Principal Component Analysis (PCA) was used. Some physico-chemical parameters observed were temperature, brightness, pH, salinity, coated oxygen (DO), phosphate, nitrate, and ammonia.

There are numerous disadvantages of chemical fertilizer as the soil can take really long to replenish and attain its natural form. Soil need to be fit as it is most important factor for growth of plant. Due to the decrease in soil quality farmers have started using alternate substances such as biofertilzers which provide right amount of nutrients and are eco-friendly.

A field experiment was conducted in kharif 2011on blackgram genotype T-9. The experiment was laid out in randomized block design with three replication and thirteen treatments. There was significant improvement recorded in yield, nutrient content, uptake and physico-chemical properties viz. pH, electrical conductivity, organic carbon and available N and P of soil under black gram crop. Grain yield was increased by 47.06% in treatment T13 over control while, organic carbon showed significantly highly positive correlation with available nitrogen (r=.878) in post harvest soil.

Phosphorous is one of the most abundant metallic element found in the earth’s crust and present in soils in both organic and inorganic forms. Though it is present in high concentration, only 0.1% of the total P is available to plant because of poor solubility and its fixation in soil with other metallic elements in the soil such as Ca, Al, Fe to form calcium phosphate, aluminum phosphate and ferrous phosphate and thus becomes unavailable to plants.

A study was undertaken to evaluate the efficiency of phosphatic nano fertilizer under pot culture trail. The experiment was conducted during the summer 2017 to know the effect of different levels of nano and chemical phosphatic fertilizer on NPK nutrient (Nitrogen, phosphorus and potassium) content and uptake by pearl millet crop in Vertic Ustocrepts medium black calcareous soil. The experiment was containing control with seven different treatments.

Microbial biodiversity in the soil plays a significant role in metabolism of complex molecules and help in plant nutrition. Phosphate solubilizing Bacteria (PSB) increases availability of phosphorus, therefore reducing the application of chemical fertilizers. The present study was aimed to isolate and characterize the selected phosphorus solubilizing bacteria from Rhizospheric regions of Walnut (Juglans regia).

Expanding utilization of chemical fertilizers in farming make nation self-ward in food production for generation however it deteriorate condition and cause destructive effects on living beings. Overuse of chemical fertilizers in farming is exorbitant and has different adverse effects on soil richness. Further, soil microorganisms assume an essential part in the plant development and improvement by different means viz. nitrogen fixation, phosphate solubilisation, phytohormone generation and so forth. Hence, bio-inoculants for farming purpose i.e.

Environment pollution and the food shortage are the biggest problem faced by human beings. As the world population increase food requirement also increases. To fulfil the requirement of food the farmers are dependent on the chemical fertilizers which are harmful for environment. Thus the alternate to these problems are the use of biofertilizers.

Imbalanced application of inorganic fertilizer generates undesirable over soil physicochemical properties to a great extent. Short term aerobic incubation experiment was implemented with soil samples (Typic Haplustert) collected from top soil horizon (0-15cm) of cabbage field in Viraliyur, Coimbatore district of Tamil Nadu. Intention of study is towards examining the pattern of changes in pH and electrical conductivity (EC) in soil added with varied levels of fertilizers (NPK) under field capacity condition. Fertilizer was applied in accordance with the treatments viz.

The decline in the rice crop responses to applied fertilizer nutrients, inter alia, could be ascribed to emerging nutrient deficiencies on account of modern era of agriculture and inadequate or imbalanced application of fertilizers. It has become increasingly recognized around the world that N, P and K fertilizers alone are not always sufficient to provide balanced nutrition for optimal rice yields and quality, therefore, application of secondary and micronutrient elements has to be made.

Preparation of compost enriched with rock phosphate may be considered as a suitable option for utilizing the reserves of low-grade rock phosphate for enhancing the phosphorus use efficiency of crops. This research was carried out to study the effect of combined inoculation of mycorrhiza and selected rhizobacteria on soil nutrients and P uptake by rice. The experiment was conducted in Randomized Block Design with 10 treatments having three replications.

Glassware must be scrupulously cleaned. Clean all glassware as soon as possible 3 after use by rinsing with the last solvent used in it. Solvent rinsing should be followed by detergent washing with hot water, and rinses with tap water and distilled water. The glassware should then be drained dry, and heated in a muffle furnace at 400°C for 15-30 minutes. Some thermally stable materials may not be eliminated by this treatment. Solvent rinses with acetone and pesticide quality hexane may be substituted for the muffle furnace heating.
