Sounds like a stupid question but what is the difference between surface run off and leaching in terms of the nutrient cycle?

leaching is when substances that are water soluble (for example pesticides or fertilisers) are washed out of the soil. the chemicals that are leached can cause water pollution. whereas surface run off is when excess water from rain or snow etc flows over the soil. this has no environmental disadvantages
