Recommended Methods for Determining Soil Cation Exchange Capacity Donald S. Ross and Quirine Ketterings The cation exchange capacity (CEC) of a soil is a measure of the quantity of negatively charged sites on soil surfaces that can retain positively charged ions (cations) such as calcium (Ca2+)‚ magnesium (Mg2+)‚ and potassium (K+)‚ by electrostatic forces. Cations retained electrostatically are easily exchangeable with cations in the soil solution so a soil with a higher CEC has a greater capacity

"CHILD IS THE FATHER OF MAN" the famous lines by William Wordworth. It symbolizes the need of children in building a healthy nation and society. Childhood is the first stage after infancy. It is the formative period in men’s life. For their minds are very soft‚ receptive and plastic at this tender age. Children’s mind is like potter’s clay. It has to be shaped in a right manner. A child normally has to enjoy its childhood days with its parents‚ teachers‚ friends‚ etc. It is the age where fine and

Dissipation of pretilachlor in soil and field water The dissipation behaviour of pretilachlor from ready mix formulation in paddy grown field soil at all three different doses of application was studied. The mean pretilachlor recovered from the soil and field water at different time intervals from various doses applied treatments are presented in table 4. The amount of herbicide recovered on 0th day (2 hrs after application) was ranged from 104 – 247 µg / kg in soil and 12.2 -13.1 µg / mL in field

Conservation officers work for the department of natural resources or (DNR)‚ some work for state bureaus with similar names. Conservation Officers have the same or more authority as police officers. They enforce laws related to commercial and pleaser fishing‚ hunting‚ poaching and outdoor recreation and environmental infractions. They may also be known as game wardens‚ even though some of these people help protect both wildlife and land. “For 125 years Michigan conservation officers have shared

Soil properties: Some physical and chemical properties of the soil were measured‚ which are presented in Table 1. The availability of nutrients and even contaminants depends on the degree of soil acidity. The most suitable pH for soil microorganism’ activity is 7‚ as nutrient solubility depends on soil pH changes (Riser-Roberts‚ 1998). The soil used in the present study has neutral pH and therefore does not limit the activity of microorganisms or the solubility of nutrients except for phosphorus
