چکیده
Calcium Absorbed form the soil as the cation, Ca. Most calcium uptake occurs near the root tip. Poorly translocated within the plant. Deficiencies of Ca first affect the growing points of plants, including root tips. Calcium is important for cell wall formation and the integrity of cell membranes. Sensitive crops to Ca deficiency and characteristic symptoms. Crop Symptoms Peanuts Old leaves have pitted undersides. Fruits do not fill if Ca is low 15 days after pegging. Alfalfa Does not grow.

متن کاملEvaluation of Levels of Macro- and Micro-Nutrients in Workers Exposed to Electromagnetic Fields and Comparison with Levels of Patients with Leukemia
There have been much speculation and debate concerning the effect of electromagnetic fields (EMF) on body systems. Various reports have implicated excessive exposure to EMF to certain forms of leukemia. It has also been reported that EMF may cause alteration in the levels of certain macro- and micro-nutrients such as copper, zinc, selenium, calcium and iron. We have undertaken this study to det...
متن کاملApplication of nano- and micro-sized particles of cattle manure on soybean growth
Background: Cattle manure (CM) is the most common organic fertilizer used by farmers. However, its usually slow decomposition leads to the use of chemical fertilizers. Therefore, experiments on nano- and micro-sized particles of CM were conducted to evaluate the possibility of accelerating its decomposition in soil. Methods: The effects of a sole application of CM in different sizes (nano-, mi...
