Effects of alkaline fertilizer and rice cultivation (Oryza sativa L.) on remediation of soils polluted with cadmium (Cd)

Accumulation of heavy metals in the soil: The analysis of the soil realized after the last cutting of the Ray Grass (Figure 3), shows a significant decrease of the content

To confirm this, a series of energy filtered TEM (EFTEM) chemical maps were made on several of the FIB sections. Representative Si and Ca jump ratio EFTEM

In addition, compared to mineral fertilizer, water soluble P concentration is up to five times lower in the presence of frass, which prevents P from loss and sorption onto

These relationships reveal that threshold values for this soil P test was influenced not only by those factors affecting the equilibrium of inorganic phosphate between the solid

Soil samples were taken from cocoa growing areas and the Soil Diagnostic method was used to establish general fertility recommendations for each region.. Sample calculations

A soil diagnostic model was developed to help the agronomist to easier understand and interpret soil chemical data (level of nutrients, N/P and K-Ca-Mg ratios) in order to

Phosphorus fractions (mg P kg -1 soil) determined for fertilized and unfertilized Andisols (PN and PEH) Values in parenthesis correspond to percentage of the sum of organic

Two soil bulk densities, 1.2 and 1.4 g.cm -3 , were selected to assess the effects of soil compaction on Lactuca sativa growth in the presence of phosphate fertilizer and
