Organic fertilizer feeds plants, while also improving the natural soil ecosystem. It promotes healthy growth and keeps soil free of compaction. When used properly, organic fertilizer also help maintain healthy root systems and prevent the development of pests and diseases.
Organic Ingredients
Many common animal byproducts and plants can be used in organic fertilizers. Some nutrients are granular and slowly release over the growing season. Other nutrients come in liquid or as foliar forms which deliver nutrients to the roots or watering.
Fertilizers made from rock phosphate are one type of mineral-based organic fertilizer, which contain high levels of nitrogen and phosphorus along with trace elements like calcium, iron and magnesium. This fertilizer is not easily dissolved by water and will remain in the soil until it is used by plants.
Kelp is another organic source of nutrients rich in nutrients. It has high levels nitrogen and phosphorus, and contains a variety minerals that are hard to find in other forms. It can be used with other soil amendments to build a rich layer of minerals that will support a healthy, sustainable garden.
Liquid Organic Fertilizers
There are many liquid organic fertilizers available. These fertilizers are more effective than their dry counterparts. They provide a burst to the root system or can be foliar-fed by spraying. These organic fertilizers are used to nourish specific crops or to add nutrients after heavy application of other materials like manure.
Spikes for Soil Boosting
Organic fertilizer spikes can be used to produce the best results. These spikes can be placed in containers or in beds. They have a formula that increases soil organic matter, helps to break down fertilizer for plants, and boosts beneficial microbes in the soil.
These organic spikes are a great addition to other soil-building products and nutrient-enhancing items. They can increase plant-disease resistant, reduce weeding, and increase harvest when combined with other soil-building products. They can be used at a rate between two and three spikes per container, or per square foot of bed space, during the growing year.
Other organic raw materials
Organic gardening requires fertilizers that are free from synthetic chemicals. OMRI is an independent organization that reviews products and allows manufacturers to identify their products with an OMRI product list.
The OMRI list includes a wide range of fertilizers, from low-cost general purpose fertilizers to specialty fertilizer for particular crops. A quick search of the below online retailers will yield many quality organic fertilizers that can be used in your garden. Some even come with OMRI labels.
