Fertilized black soil samples are prepared by mixing desired amounts of fertilizers in the black soils having 10% gravimetric moisture content. Two black soil samples were collected from two different locations of Maharashtra State (India). Three different chemical fertilizers viz., Urea, Di-Ammonium Phosphate and Potash are used. Measurements of complex dielectric constants of these soil sampl...

Nursery experiments were conducted to select the suitable bioinoculants with locally available organic source to improve quality seedling production of Jatropha curcas L. Two months old Clones was procured from the Mission Biofuel India Pvt. of Madurai district, Tamilnadu, India. Clones were transplanted in a mixture of UnSterilised sand, Soil, and Farm Yard Manure (FYM) in the ratio of 2:1:1 i...

A 2-year field study was conducted to determine the influence of the timing of application and different slow release nitrogen (N) sources with different nitrogen rates on the growth and quality of a turfgrass mixture. Three different timings were used for nitrogen application: annually, once every 3 months, and once every 6 months. Three nitrogen sources (ammonium nitrate and two slow-release ...

Nitrogen is abundant in the earth's atmosphere but, unlike carbon, cannot be directly assimilated by plants. The limitation this places on plant productivity has been circumvented in contemporary agriculture through the production and application of chemical fertilizers. The chemical reduction of nitrogen for this purpose consumes large amounts of energy and the reactive nitrogen released into ...

Aim: Many countries import potassic fertilizers due to dearth of K-mineral deposits. Therefore processes to obtain K-nutrient sources from sea bittern were developed by our Institute. The present investigation evaluated the fertilizer potential of three different sea bittern-derived (SBD) potassium forms developed viz., potassium schoenite, potassium nitrate and potassium ammonium sulfate on ma...

In the present paper, new environmental-friendly fertilizer components were produced in biosorption process by the enrichment of the biomass with zinc, essential in plant cultivation. The obtained new preparations can be used as controlled release micronutrient fertilizers because microelements are bound to the functional groups present in the cell wall structures of the biomass. It is assumed ...

This study was carried out during 2004 and 2005 seasons on eight years old Arabi pomegranate trees grown in sandy soil to investigate the influence of microbial biofertilization on tree growth, yield, fruit quality and leaf minerals content. Microbial inoculum (Azotobacter spp. Azospirillum spp. and Bacillus megatherium which found in (Biogein, Nitrobine, phosphorein), in addition, arbuscular m...

It is very difficult to meet the demands of increasing population with such fewer resources. Loss soil fertility, pests, and lack nutrients has resulted in a decrease agricultural production. This increased importance fertilizers agriculture. Since chemical adversely affect biofertilizers were brought into use. These are substances that contain living or latent cells, even micro-organisms. They...

There have been several recent developments in slow-release fertilizers. These materials supply nutrients continuously over an extended period in contrast to water soluble fertilizers which are immediately available after incorporation in moist soil. Slow-release fertilizers are not subject to rapid leaching loss and do not easily burn plants from over-application. The major need for slow relea...
