Dirt WPR 2 Practice Test

Adding compost or well-rotted manure is beneficial for improving soil organic matter content because these materials are rich in organic material that enhances the soil's structure, fertility, and ability to retain moisture. Compost and manure introduce a diverse range of microorganisms and nutrients into the soil, which contribute to the formation of humus. Humus is essential for increasing soil aeration, improving moisture retention, and providing a reservoir of nutrients that plants can utilize. This practice not only boosts the organic matter levels in the soil but also promotes a healthier ecosystem, which in turn supports robust plant growth. Sustainable soil management practices often emphasize the importance of incorporating organic amendments like compost and manure to build and maintain healthy soil ecosystems.
