Final answer:
Horticulture can be a sustainable form of farming through methods like organic fertilization and letting soil regenerate by lying fallow. Extensive horticulture practices crop rotation for soil recovery, while soil tilling is more indicative of non-sustainable agriculture.
Step-by-step explanation:
When considering whether horticulture is sustainable, it's important to understand that there are different methods of cultivation, such as extensive horticulture and intensive agriculture. Horticulture incorporates organic methods of fertilization and pest control, making it a sustainable form of farming. However, it can deplete the nutrients in the soil over time, necessitating the practice of letting plots lie fallow to regenerate nutrients. Extensive horticulture involves rotating crops across multiple plots to allow the soil to recover, which is an aspect of sustainable practice.
On the other hand, conventional agriculture often relies on practices like soil tilling which is more indicative of non-sustainable agriculture due to its potential to lead to soil degradation and erosion. Additionally, sustainable agriculture aims to maintain bioproductivity indefinitely, which can involve methods like rotating crops and allowing land to rest. This contrasts with some conventional methods that might prioritize immediate yields over long-term sustainability.
