What are the different methods of improving soil fertility?

Organic farmers seek to “build the soil” or enhance its inherent fertility by using crop rotations, animal and green manures, and cover crops. Crop rotation and tillage practices must provide an appropriate seedbed and pest control while minimizing erosion.

What is the importance of soil fertility and soil productivity?

Soils feed the plants which in turn feed the animals that feed us. Including soil in this important chain will help guarantee its success. Soil provides the support or foundation for plants and most of the nutrients. Soil is accumulated decomposing plant and animal matter with aging parent material.

Losing topsoil to erosion contributes to a loss of inherent soil fertility levels of nitrogen, P, K, and thus to a decline in potential crop yield. The addition of manure and fertilizer can supply needed crop nutrients and help offset some loss of inherent fertility caused by soil erosion.

What color is nutrient rich soil?

Soil color is produced by the minerals present and by the organic matter content. Yellow or red soil indicates the presence of oxidized ferric iron oxides. Dark brown or black color in soil indicates that the soil has a high organic matter content. Wet soil will appear darker than dry soil.
