Soil organic matter is the backbone of nitrogen supply in organic production, and cultural practices to manipulate nitrogen start with building soil organic matter. The nutrient release occurs predominantly in the spring and summer, so summer crops benefit more from organic-matter mineralization than winter crops. Generally soils with more clay silt and organic matter have a higher CEC and the CEC decreases with increased sand content. In cases where low-residue horticultural or root crops are grown on farmland with relatively low soil organic carbon levels, it is important to include crops that produce abundant residues in the rotation. contains 2-10 % organic matter.

The organic matter component of the soil system is only a small fraction of the topsoil horizon (ranging from 1-5% or greater by dry weight depending on the soil type and other formation factors), but essential for the soil physical, biological, and chemical functions and general soil ecosystem services. That’s why it’s important to maintain a balance to maintain soil cover that ultimately breaks down. However, for crop yield-scaled land the effect of organic farming on biodiversity is highly debated due to the significantly lower yields compared to conventional farms. Why is organic matter important for crop production ? Also, the pH range for your growing crops is important, especially when you are putting together a nutrient management plan for your organic garden. Where the soil is exploited for crop production without restoring the organic matter and nutrient contents and maintaining a good structure, the nutrient cycles are broken, soil fertility declines and the balance in the agro-ecosystem is destroyed.
