Organic Garden Fertilizer

Organic gardening is a popular alternative method of vegetable gardening. Animal manure and composted plant materials are the most common forms of organic garden fertilizer. Cover crops and mixed organic materials are another form of natural organic fertilizer. In addition to the macro nutrients, nitrogen (N), phosphorous (P), and potassium (K), natural organic fertilizer adds other micro-nutrients.

Benefits of Organic Garden Fertilizer

Nutrients are released slowly from organic fertilizer, which benefits the growing crop over a longer period of time. Additions also improve soil texture as well as the ability to hold water and nutrients. Organic matter releases acids when decomposing which aid in converting some natural mineral additives into plant usable forms.

Types of Natural Organic Fertilizer

Animal manure is among the best sources for fertilizer and organic matter garden amendments. The type and condition of the animal as well as the feed determine the quality of the animal manure. Duck manure may have up to twice the nitrogen, almost ten times the phosphorous, but similar levels of potassium as cow manure. Evaluate organic fertilizer needs before applying a particular type.

Plant manure is obtained through composting plant material. Piling up plant material and allowing it to decompose long enough with proper management, produces a good organic garden fertilizer. The compost pile must be managed to speed up the composting time as well as produce a better end product. Composters are available to aid in the process, from many garden centers. Some communities also have composting locations where compost can be purchased.

Cover crops are plants that are planted in the off season and later plowed under to add organic material to the soil a few weeks before planting a vegetable crop. There are additional benefits to cover crops such as soil erosion protection and wildlife habitat.

Determining Need for Organic Garden Fertilizer

Garden soils should be tested to determine application amounts. This greatly improves the chances for a successful harvest. Contact local extension agents for help in determining soil nutrient needs. Organic gardeners that plan on selling produce as a certified organic farm should check with their state or other agencies to know what their official rule is for claiming an organic status before deciding on a fertilizer. Fertilizers should be added at least a few weeks before planting to provide optimum growth. By planning ahead and knowing as many factors as possible, proper use of organic garden fertilizer will provide a great benefit.
