Organic vs Inorganic Fertilizer

有机肥料和无机肥料之间的差异可以在各种角度讨论。在此之前,肥料是通常用于改善植物营养的物质。农业的成功主要取决于crop. There are a number of factors that influenced the crop growth. Plant nutrients are an important group out of them. It is important to supply an adequate quantity of a particular nutrient for plant growth and it depends on both the behavior of that nutrient in the soil as well as the utilizing capacity of the crop root system. If these elements are not available in an optimum amount to the plant that will adversely affect to the plant growth and quantity and quality of the yield. One of the main characters of fertilizers is that it can replace the chemical elements taken from thesoilby previous crops. This may lead to enhancing the natural fertility of the soil.

Fertilizers come in organic or inorganic forms to the market. But now it is recommended that the Integrated Farming should be used. This is a new approach to plant nutrition by obtaining the nutrients from both inorganic and organic sources to maintain and sustain soil fertility and enhance crop productivity.

What are Organic Fertilizer?

Organic fertilizers are fertilizers derived from animal or vegetable matter as well as human excreta. It contains all essential plant nutrients and the nutrients release is enhanced by the warm and moisture levels of the soil. Either byproduct or end product of naturally degradable plant or animal-based materials, undergo a分解process to produce organic fertilizers. When the decomposition starts the parts of its organicmanurefirst degrade into primary nutrients and further decomposition results in secondary nutrients too. When applying organic fertilizers, it is important to avoid materials that contain high C: N ratio, as it is not suitable for the plant growth and it should be applied and buried in the soil to get the maximum benefit. So, legumes and composite plants that contain high氮are not used as decomposing materials.

• Examples of green manure – Sun hemp, Sesbania rostrata, Gliricidia,wild sunflower.

• Examples of Animal origin – dung, urine, grasses and feed stuff, bedding of animals.

What are Inorganic Fertilizers?

Inorganic fertilizers are also known assynthetic fertilizersand they are ready to use in plants. These synthetic fertilizers come in single-nutrient or multi-nutrient formulas. There are 16 nutrient elements considered as essential for plant growth. They divide into two categories; primary elements and secondary elements. Modern chemical fertilizers include most important primary elements, which are nitrogen,phosphorus, and钾. Secondary important elements aresulfur,magnesium和钙。在施用无机肥料时,重要的是要考虑其浓度,因为高营养水平会增加燃烧植物的风险。无机肥料的另一个缺点是迅速释放元素,这些元素深入土壤和水,但植物无法进入它们。无机肥料的一些优势在短期内便宜,从长远来看,它增加了土地。此外,它更容易使用和准备。

What is the difference between Organic and Inorganic Fertilizer?

•无机肥料含有合成材料,但有机肥料含有天然可降解的化合物。

• Generally, high application rates are necessary for organic fertilizer but,comparatively fewer amounts are needed for inorganic fertilizer.

•有机粪便提高土壤的质量,但产量将较低。无机肥料的相对较重的应用会燃烧植物,过量使用肥料可能会导致土壤中的毒性。

• Organic manure is not harmful to the land and it improves the physical, chemical and biological conditions of the soil but, singular use of chemical fertilizers has an adverse effect on the soil structure.

• Application of organic manure helps to prevent soil erosion as it forms water stable aggregates.

•有机粪便中营养物质的可用性是持久的。

Use of both chemical and organic fertilizers together gives more benefits than applying them separately which increase physical and microbiological properties of the soil. This will increase the availability of nutrients as well.
