Question

scenario 6: across many grassland regions used for agriculture, soil health is declining due to a common practice calling tilling. tilling is when farmers break up the soil before planting crops. while this method helps prepare the ground for seeds and controls weeds, it also exposes the soil to wind and rain. over time, frequent tilling causes the soil to lose its structure and organic matter, making it more likely to erode and less likely to hold water. as a result, the land becomes drier and less fertile, so farmers have to rely on more fertilizers to grow the same number of crops. scientists and farmers are now exploring alternative methods to protect the soil, preserve nutrients, and make grassland agriculture more sustainable.

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:

For question 11, the problem is soil degradation (less fertile, drier, erodible) from tilling. For question 12, sustainable farming (like no - till, cover crops) can protect soil (nutrients, structure).

Answer:

1. Soil degradation (drier, less fertile, erodible) from tilling affects grassland.
2. No - till farming (or cover crops) to protect soil (nutrients, structure) for sustainable grassland.
