Effect of Acidic Biochars on Some Chemical Properties and Nutrient Availabilities of Calcareous Soils
Low organic matter content and alkaline pH of calcareous soils in arid and semi-arid regions are the main reasons for the low nutrient availabilities for plants in these soils. One way to improve the chemical properties and fertility of calcareous soils is the application of organic substances such as biochar produced from pyrolysis of organic wastes. However, biochars have an almost predominan...
متن کاملLeaf and Soil Nutrient Relations of Elaeocarpus joga Merr. in Oceanic Island Calcareous Soils
The leaf nutrient status and stoichiometry of nitrogen (N), phosphorus (P), and potassium (K) were determined for Elaeocarpus joga trees in Guam’s dominant calcareous soils to understand nutrient limitations in limestone soils of Oceania and contribute to global databases on leaf economic spectrum studies. Supplemental N, P, or K was added to soils to determine plant growth and nutrient concent...

متن کاملIdentification of trace mineral and nutrient deficiencies as an adjunct to treatment of eating disorders
Biochemical data from 90 patients presenting to a general practice over the previous five years has been analysed to identify specific nutrient deficiencies. It is a common complaint amongst families of eating disorder (ED) patients that on first presentation to their GP “the bloods were normal so the GP said that there wasn’t anything wrong”. This factor may contribute to delayed treatment of ...
متن کاملPercolation Phosphorus Losses in Calcareous Furrow-irrigated Soils
Groundwater seepage contributes to irrigation return flows and surface waters. Knowledge of phosphorus (P) concentrations and loads in percolation water that enters the vadose zone and groundwater is necessary to assess and manage water quality. We measured the P in water leached below the crop root zone in a furrow-irrigated Pormeuf silt loam. Vacuum operated percolation samplers were used to ...
