Question

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 soils water - holding capacity d organic fertilizer runs off more readily into waterways, leading to nutrient overload

Explanation:

Synthetic fertilizers are formulated to have specific ratios of macronutrients (like nitrogen, phosphorus, and potassium). This allows farmers to target the exact nutrient needs of their crops more precisely than organic fertilizers, which have more variable nutrient compositions.
Organic fertilizers improve soil texture and water - holding capacity (so C is wrong for synthetic). Organic fertilizers also tend to release nutrients more slowly and can have a longer - term presence in the soil compared to some synthetic fertilizers (so B is wrong). Both synthetic and organic fertilizers can cause nutrient runoff if misapplied (so D is wrong).

Answer:

A. synthetic fertilizer can provide more targeted macronutrients to the crops
