Example text

Deficiencies of other plant nutrients can and do occur, potentially limiting yields. Organic or residuals derived amendments such as composts, biosolids and manures, being derived from plant material and manures, will contain the full suite of required plant nutrients. Composts and biosolids can be added to soils to meet the nutrient needs of a crop. Composts can also be added to soils as a soil conditioner or as a mulch. Soil conditioners are typically incorporated into the surface 6″ or 15 cm of the soil.

The soil ecosystem is sometimes described as the “soil food web”. Thinking of the ecosystem as a food web emphasizes the relationships among the different types of organisms as they decompose organic residues. Bacteria favor easily degradable substances in the residues, such as sugars, starch, and proteins, while fungi can digest woody materials. The bacteria and fungi incorporate nutrients from the residues into their bodies, and release any excess nutrients as soluble ions that can be taken up by plants.

Direct, sensual encounters with the environment arise, and as citizens participate in the process of growing their own food, they develop their own awareness and reflections of what that means to them (Bhatti and Church 2001; Delind 2006). This process of engagement and learning can extend to children and young adults, as well; in parks today we can see models for mutually beneficial arrangements where students aid in the creation, restoration, or upkeep of shared green space, enhancing the environment of their community and learning biology and ecology in the process.
