My research interest
 
 
       My main research topic is focused in the dynamics of chemical elements in Agricultural soils. The knowledge of pool of elements and ions movement in soils has a big importance in environmental and agriculture issues. The ions can be the nutrients that plant need for growing, on a hand, and can be the contaminants that moved throw soil reaching groundwater, on the other hand, producing pollution. My first research was about magnesium in soils cropped with coffee plant that exhibited deficiencies with these element. We stated that continuous potassium fertilization could drives a difficulty to the plant for uptaking magnesium, and the balance between the two nutrients was necessary to control magnesium deficiencies. Next, I was interested in knowing how much fertilizing was lost by lixiviation after the application in soils. There was a strong relationship between the clays types in soils and the amount of fertilizing moved out the soil. Soils developed from volcanic ash have not the ability of retain cations. Now I am interested in the behavior of heavy metals in soils, and why they can be took for the root's plant and translocate to their tissues, and became part of the food chain. This is a concern for the food security.

  1. Martha, this is a good research statement. You did an excellent job! You have the ability to organize a paragraph in an effective way, but it would be good if you could make your concluding sentence (your summary sentence) stronger.

    Also, your grammar needs to be improved. It is not helpful to correct all the errors, but below are some error corrections.

    1. My main research topic is focused in the dynamics of.... - My main research topic focuses on the dynamics of ....
    2. on a hand & on the other hand - one one hand & on the other hand
    3. We stated that continuous potassium fertilization could devise a difficulty to the plant for uptaking... - My research found that continuous potassium fertilization could create difficulty for plants to uptake ...
    4. Soils developed from volcanic ash have not the ability .... - Soils developed from volcanic ash do not have the ability ...

    Overall, wonderful job!
