SAOSIS Organic Compost is organic matter that has been decomposed and recycled as a fertilizer and soil amendment. Organic Compost is a key ingredient in organic farming. At the simplest level, SAOSIS Organic Compost is made by the process of composting which requires making a heap of wetted organic matter known as green waste (leaves, food waste) and waiting for the materials to break down into humus after a period of weeks or months. The decomposition process is aided by shredding the plant matter, adding water, ensuring proper aeration by regularly turning the mixture and special cluster of bacteria that help in decomposing.
Organic Compost product specification:
- Nitrogen (N) = 0.90% – 2%
- Phosphorous (P) = 0.50% – 2%
- Potassium (K) = 0.90% – 1%
Other Trace Elements or Micro Nutrients necessary for healthy plant growth found in Organic Compost are
- Boron (B)
- Calcium (Ca)
- Chlorine (Cl)
- Copper (Cu)
- Iron (Fe)
- Manganese (Mn)
- Molybdenum (Mo)
- Zinc (Zn)
- Calcium (Ca)
- Magnesium (Mg)
- Sulfur (S)
Why SAOSIS Organic Compost is needed?
The soil is the heart of an organic system, feeding plants via intricate relationships with microflora and fauna. Microbial activity within the soil processes Organic Compost to provide a range of minerals and nutrients to the plants. These are used by the crop to achieve healthy, vigorous growth. Biodiversity within the system and optimum crop health, work together to minimize the incidence of pest and disease attack.
Organic Compost energizes the soil food web, which is made up of microscopic bacteria and fungi, along with earthworms, crickets, and many other life forms. Many fungi form symbiotic, or mutually rewarding, partnerships with plant roots, making it possible for vegetables to feed themselves more efficiently. Research shows that Organic Compost enhances the ability of tomatoes and other vegetables to stand up to common diseases and may improve their flavor and nutrition, too. Organic Compost also helps the soil retain moisture. Through composting you enhance your garden’s ability to grow healthy plants while reducing your volume of trash.
What Is The Difference Between SAOSIS Organic Compost And Chemical Fertilizer?
The most simplest way to distinguish between Organic Compost and chemical fertilizer is to remember this: Organic Compost feeds the soil and fertilizer feeds the plants.
Fertilizer adds to the soil’s nutrient supply, but instead of feeding the soil food web, the ingredients in fertilizers are intended to meet the needs of fast-growing plants. While recommended amounts of compost can be quite general, fertilizer application rates are based on the needs of plants. Either organic or conventional fertilizers work well for vegetables, but organic fertilizers have been shown to be friendlier to the soil food web. Chemical fertilizer can also feed composting, but continual use may throw soil chemistry out of balance and discourage microbes. See fertilizer to explore your fertilizer options.
Benefits of using Organic Compost are as follows:
- Nutrient Supply; Compost contains significant quantities of macronutrients, such that the additional application of phosphate and potash fertilizers often becomes unnecessary.
- Reduced nutrient losses and improved cation exchange capacity; Light textured soils (in the sandy categories) possess low cation exchange capacities (CEC) and adding compost raises the CEC of these soils. This enables the soil to better hold onto nutrients, such as potash and nitrogen, which would otherwise leach beyond the rooting depth.
- Better plant survival and growth; Although ideal soil conditions are found under long-term grassland and woodland areas, most
landscapers have to deal with very poor soil conditions. Most landscape trees and shrubs have been selected to tolerate poor soil conditions, but they cannot tolerate compacted soils or seasonal water logging. Organic matter is therefore required to improve soil conditions, providing benefits outlined within this section of the manual. Good growth during plant establishment, and sustained
growth and plant quality need adequate levels of organic matter in the soil.
- Reduction in soil compaction; Many experiments have shown that organic matter improves the aggregate strength of soils.
- Improvement in soil water holding capacity; As one of the overall benefits of improved soil structure, the infiltration of rainfall and irrigation water is improved, as is soil water holding capacity – especially on light soils.
- Control erosion and weeds (by mulching with compost); Organic Compost mulches act as a physical protective barrier to the soil surface. They can provide enormous benefits to landscape plantings through weed control (when a coarse particle size grade is used),
moisture conservation, moisture percolation and erosion control
- Microorganisms increase soil aggregation, recycle nutrients and suppress soil borne diseases; The organic matter in compost is populated by microorganisms which supplement those already present in the soil. The microorganisms utilise organic matter as an energy source and release polysaccharides and humic substances that help form soil aggregates and improve the structure of soil.
