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

Annotation:

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 Considerable growth responses to two differing phosphatic fertilizers (rock phosphate and superphosphate) applied to Pinus radiata (D. Don) were previously reported by the authors (Forest Science 11, 1965). At that time the experimental site had carried two rotations of trees, the first unfertilized. The same site has now been grown through a similar period of time in the third rotation (to first thinning) with no further fertilizer applications. Growth responses, foliage and soil chemical analyses have been compared with those obtained over the first fertilized rotation. Results show

The risks of contaminants accumulating in soils and crops due to inadvertent addition of impurities in agricultural fertilizers and soil amendments were assessed for Australian conditions. Elements considered of concern were arsenic (As), cadmium (Cd), fluorine (F), lead (Pb) and mercury (Hg). Consideration of background concentrations of these elements in Australian soils, inputs to soil in fertilizers and offtake in harvested crops indicates that Cd and F will accumulate in fertilized soils at a faster rate than As, Pb or Hg.

This thesis examines the response to P fertiliser by wheat crops growing in the vertosol soils of the low rainfall areas of the northern grain zone of eastern Australia. Farmers in this region depend on water accumulated from rainfall over a fallow period and stored in the subsoil to increase wheat grain yield beyond that normally achievable from in-crop rainfall and to decrease the production risks due to rainfall variability. The large variability in stored water, seasonal rainfall and subsoil properties result in extremely varied yield and yield responses to P fertiliser between seasons and

The value of IAP and SAC of AlPO4 differs from soil to soil and increases with increasing P added to soil in acid soils and for calcium phosphate in basic soils.

Abstract CPI & Petrochemicals constitute a huge, complex and highly diverse industry which forms an integral part of the US economy. It covers converting various raw materials (about 10 of them), the most important ones being organic in nature such as oil, natural gas and coal whilst others are inorganic in nature such as ores / elements taken from the earth (phosphates, sulfur, potash etc), air (nitrogen, oxygen) and water (chlorine, hydrogen). Conversion of these base materials produce about 300 different “intermediates” which then go into production of about 30.000 plus consumer product

The paper presents the basic characteristics and prerequisites for improving the production of butter lettuce "Shangore" in order to obtain guidelines in the application of lettuce cultivation technology, stable yield, increased nutritional value and uniform quality. Fertilization treatments in the experiment included: phosphate-based mineral fertilizer, humic acid-based organic fertilizer, and liquid organic-mineral fertilizer. The results of this research indicate that the average value of lettuce yield was the highest in the application of fertilizers with potassium phosphate and the applic

Abstract: Phosphorus is one of the least available macronutrient in the soil. The high affinity phosphate transporters are known to be associated with phosphate acquisition under natural conditions. Due to unique interactions of phosphate with soil particles, up to 80% of the applied phosphates may be fixed forcing the farmers to apply 4 to 5 times the fertilizers necessary for crop production. Efficient uptake and utilization of this essential nutrient is essential for sustainability and profitability of agriculture. Many predictions point to utilization/exhaustion of high quality phosphate r

Beneficial use of reclaimed wastewater (RW) and biosolids (BS) in soils is accompanied by large input of sewage-originated P. Prolonged application may result in P accumulation up to levelsBeneficial use of reclaimed wastewater (RW) and biosolids (BS) in soils is accompanied by large input of sewage-originated P. Prolonged application may result in P accumulation up to levels that impair plant nutrition, increase P loss, and promote eutrophication in downstream waters. This study aims to shed light on the RW- and BS-P forms in soils and to follow the processes that determine P reactivity, solu

New potential for engineering chloroplasts to express novel traits has stimulated research into relevant techniques and genetic processes, including plastid transformation and gene regulation. This proposal continued our long time BARD-funded collaboration research into mechanisms that influence chloroplast RNA accumulation, and thus gene expression. Previous work on cpRNA catabolism has elucidated a pathway initiated by endonucleolytic cleavage, followed by polyadenylation and exonucleolytic degradation. A major player in this process is the nucleus-encoded exoribonuclease/polymerasepolynucle
