Abstract:

Inorganic fertilizers with major nutrients are likely to be contaminated with some micronutrients. Fertilizers, utilized in Saudi Arabia, were analyzed for their total and water-soluble content of Fe, Zn, Mn and Cu. They represented three categories namely: phosphatic, solid multiple nutrient fertilizers (SMNF) and water-soluble multiple nutrient fertilizers (WSMF). Total iron content in examined fertilizers was higher in phosphatic fertilizers and lower in WSMF. Nevertheless, only a very small portion of the total iron content is likely to be available to plants. It was estimated, on the basi

Abstract:

Chemical phosphatic fertilizers are mainly produced from phosphate rocks, a natural reserve that is depleting rapidly. These chemical phosphatic fertilizers are polluting the environment at an alarming rate as a result of injudicious application to farmlands. On the other hand, phosphate-solubilizing biofertilizers (PSBs) are often considered better alternatives to industrial phosphatic fertilizers in many ways. PSBs are microorganisms capable of solubilizing insoluble forms of phosphate into soluble plant-usable forms. This paper is written with the objective of discussing the impacts of phos

Guano is a material originally from sea bird or bat excrement. This material is an important source of P fertilizerduring nineteenth century and the early part of twentieth century. The development of artificial fertilizers and the depletion of guano deposits in Peru caused guano negligibled from world fertilizers trading. Recently, guano appeared in fertilizers trading and sciencetific publications again due to the development of organic farming and increasing the price of energy sources for fertilizer manufacture. Based on its origin, guano is classified into sea bird and bat guanos; and bas

Abstract:

Mixing non-phosphatic salts with fertilizer P influences the solubility and mobility of P in soils. Little evidence, however, is available regarding the mechanisms causing such effects. The object ives of this study were to investigate the effects of mixing fertilizer P with (NH4)2SO4, MgSO4 or (NH2)2CO on the diffusion of P in a calcareous soil (Gleyed Rego Black Chernozem), and to identify the causes for such effects. To the surface of 50-mm-long soil columns, maintained at field capacity water content, 32P-labelled monocalcium phosphate (MCP) was applied alone or in combination with (NH4)2S

Abstract:

Alternative tactics for improving phosphorus nutrition in crop production are needed in China and elsewhere, as the overapplication of phosphatic fertilizers can adversely impact agricultural sustainability. Penicillium oxalicum P4 and Aspergillus niger P85 were isolated from a calcareous soil in China that had been exposed to excessive application of phosphatic fertilizer for decades. Each isolate excreted a number of organic acids into, acidified, and solubilized phosphorus in a synthetic broth containing insoluble tricalcium phosphate or rock phosphate. Isolate P4, applied as a seed treatme

One of the major essential macronutrient for plant is phosphorous and is applied to soil in the form of chemical phosphatic fertilizers which is immobilized rapidly and becomes unavailable to plants. Microorganisms are involved in the transformation of soil P and is thus an integral part of the soil P cycle. In particular, soil microorganisms are effective in releasing P from inorganic and organic pools of total soil P through solubilization and mineralization. P-solubilization ability of the microorganisms is considered to be one of the most important properties. The adverse impact of chemica

Abstract:

Phosphorus (P) is a major limiting nutrient reducing crop yields especially in weathered soils of the subtropics and tropics. P exhibits poor mobility and availability to plants in soil. To overcome P deficiency in soil, phosphatic fertilizers are added. Global phosphate rock reserves are finite, and the addition of phosphatic fertilizers is not financially and ecologically sustainable. Mungbean (Vigna radiata (L.) Wilczek) is important grain legume for nutritional security. Attempts are being made to develop mungbean varieties with better P-use efficiency through enhanced P uptake and utiliza
