The correct answer is: D) All of the above

Soil testing is an important practice for determining nutrient levels, crop selection, and fertilizer recommendations.

  • Determining nutrient levels: Soil testing can help you determine the levels of essential nutrients in your soil, such as nitrogen, phosphorus, and potassium. This information can help you decide whether you need to add fertilizer to your soil.
  • Crop selection: The nutrient levels in your soil can affect which crops will grow well in your garden. Soil testing can help you choose crops that are well-suited to your soil conditions.
  • Fertilizer recommendations: Soil testing can help you determine the amount and type of fertilizer that your soil needs. This information can help you avoid over- or under-fertilizing your crops.

In addition to these three main benefits, soil testing can also help you identify other problems with your soil, such as acidity, salinity, and compaction. This information can help you take steps to improve the quality of your soil and maximize your crop yields.

Soil testing is a relatively simple and inexpensive process that can provide you with valuable information about the condition of your soil. If you are serious about gardening, soil testing is a wise investment.
