Fertilizers

Nutrient Cycle: This is the process by which nutrients move from the environment into organisms and then back into the environment. It's a crucial part of how ecosystems function.

Soil Erosion: This is when soil is worn away by natural elements such as water or wind, or by human activities like farming. It can be exacerbated when there aren't enough nutrients in the soil, which is one reason why fertilizers are used.

Crop Rotation: This is a farming practice where different types of crops are planted in the same area over sequential seasons. It helps maintain soil fertility and can reduce dependency on artificial fertilizers.
