Farmers need to make many decisions about how they grow their crops. One of these decisions is whether to use synthetic fertilizer or organic fertilizer, such as manure.
An advantage of using synthetic fertilizer instead of organic fertilizer is that
A synthetic fertilizer can provide more targeted macronutrients to the crops
B) synthetic fertilizer remains in the soil longer than organic fertilizer does, reducing the volume needed and, therefore, the cost to the farmer
c) synthetic fertilizer adds to soil texture and increases the soil's water-holding capacity
organic fertilizer runs off more readily into waterways, leading to nutrient overload
