3. Micronutrients

There are 7 essential plant nutrient elements defined as micronutrients [boron (B), zinc (Zn), manganese (Mn), iron (Fe), copper (Cu), molybdenum (Mo), chlorine (Cl)]. They constitute in total less than 1% of the dry weight of most plants. The following discussion focuses primarily on the soil characteristics for the micronutrients. a. Boron (B)

Molybdenum Sources and Functions

Interesting Fact about Molybdenum Sources and Functions: Plants need molybdenum to produce an enzyme that is part of nitrogen conversion. If the soil is low in molybdenum, the plants may convert the nitrates to nitrosomines. Since this would expose those who eat the plants to nitrosomines, which are implicated in cancer,this may be a good ...
