B: allowing organic matter to decompose

Did you know?

Did you know that usable forms of nitrogen in the soil can intentionally be increased through various methods? One way is by allowing organic matter, such as plant residues or animal waste, to decompose. As this organic matter breaks down, nitrogen is released into the soil, making it available for plant uptake. Additionally, planting more trees can enhance nitrogen levels as they have the ability to fix atmospheric nitrogen into the soil through specialized bacteria in their roots. Conversely, planting fewer beans can also help increase usable nitrogen in the soil, as beans are known to fix atmospheric nitrogen, depleting the available nitrogen for other plants. So, by carefully managing these practices, farmers and gardeners can optimize nitrogen levels in the soil and promote healthier plant growth.
