In healthy soil, organic matter improves the ability of the soil to infiltrate and hold water as well as releasing nutrients at rates that are consistent with what plants need. The soil is a dynamic ecosystem teeming with microscopic organisms as well as earthworms and insects that support and enhance plant growth. Organic fertilizers provide the nutrients that feed this system and help to build and sustain rich, nutrient-dense soils.
While organic products can be expensive compared to synthetic fertilizers, they provide a wide range of vital, slow-release nutrients and are less likely to damage the environment or harm beneficial microorganisms. Organic fertilizers also have the added benefit of building soil structure and improving aeration in sandy soils and drainage and aeration in clay soils by Best landscaping company in delhi.
Nutrients are delivered to plants by root systems and transported throughout the plant for essential functions like photosynthesis. Plants require a balance of nitrogen (N), phosphorous (P) and potassium (K). These are known as the primary nutrients and they are needed in large quantities for vigorous, high-quality plant growth.
The nutrient content and availability of organic material vary, as do the concentrations of nitrogen, phosphorous and potassium in the materials. Organic matter with low to moderate nutrient availability requires the nutrients in organic form to be mineralized by soil microorganisms before they are available for use by plants. This process takes time and is more difficult in cold soils.
Organic matter that has been mineralized by soil microorganisms provides a more consistent supply of nutrients to plants because the nutrients are released in a form that is easily absorbed by plants. This is why it is important to use high-quality organic materials that have been properly composted or aged before applying them as fertilizer.
Some organic materials have higher levels of salts than others, making them more likely to burn or damage plants if over-applied. It is particularly important to follow recommended application rates and thoroughly mix or work organic material into the soil before planting. The salts in some organic materials can also leach out of the soil, affecting the water quality in lakes and streams.
Homeowners can find a variety of organic materials for fertilizing gardens and landscapes at local nursery and garden centres, farm and feed stores, livestock operations, municipal green waste collection sites and landfills. These materials can be used on their own or in combination to promote vigorous plant growth, vibrant blooms and bountiful harvests. When choosing organic fertilizers, look for those that have a lower N-P-K grade because high amounts of nitrogen may lead to over-fertilization of the soil.
