Question

scenario 7: a farmer in the great plains has been growing wheat on the same fields year after year because it is a profitable crop. over time, the soil in these fields has become depleted of nutrients, and certain pests and weeds have started to appear more frequently. as a result, the wheat yields are declining, and the farmer has to use more fertilizer and pesticides to keep the crops growing. the farmer is concerned that if this continues, the land may become less productive and more difficult to farm in the future.

1. summarize the problem affecting this grassland in one sentence.
2. based on the lesson 4.3 notes, what sustainable farming practice might be helpful for this grassland? explain your answer to receive credit.

Explanation:

The problem is about summarizing an issue (soil nutrient depletion, pest/weed increase affecting wheat yield and farming difficulty) and suggesting sustainable farming practices (like crop rotation, cover - crops, organic fertilizers, integrated pest management) based on Lesson 4.3 Notes.

Answer:

1. Soil nutrient depletion, pest/weed increase make wheat yield decline and farming harder.
2. Sustainable farming practices like crop rotation (to balance soil nutrients), cover - crops (to prevent erosion and add organic matter), using organic fertilizers (to replenish nutrients naturally), and integrated pest management (reducing pesticide over - use) could help.
