Organic mulching, because it increase the soil nutrients, maintains the optimum soil temperature, restrict the rate evaporation from the soil surface, restrict weed growth and prevent soil erosion.
Organic mulching is more beneficial for sustainable agriculture, especially shredded bark which last longer and are biodegradable which, in turn, add nutrients to the soil.
Thanks Ridwan Mukaila for your valuable information i new about so many materials used but shredded bark is new for me can you please tell more about its operational process, constraints and its adaptation rate in farmer it will be really nice one to practice.
If your goal is sustainability, organic mulching is more suitable because it fulfills the concept of recycling in addition to its long-term benefits in the field that doesn't end with the end of your season
Organic mulching, because it increase the soil nutrients, maintains the optimum soil temperature, restrict the rate evaporation from the soil surface, restrict weed growth and prevent soil erosion.
Many of the studies say that to reach the goals of mulching the plastic mulches are to be used...Here it is clearly explained about the advantages of plastic mulching
Mulching is the process or practice of covering the soil/ground to make more favorable conditions for plant growth, development, and efficient crop production.
Mulch technical term means ‘covering of soil’. While natural mulches such as the leaf, straw, dead leaves, and compost have been used for centuries, during the last 60 years the advent of synthetic materials has altered the methods and benefits of mulching.
The research as well as field data available on the effect of synthetic mulches make a vast volume of useful literature. When compared to other mulches plastic mulches are completely impermeable to water; it, therefore, prevents direct evaporation of moisture from the soil and thus limits the water losses and soil erosion over the surface. In this manner, it plays a positive role in water conservation. The suppression of evaporation also has a supplementary effect; it prevents the rise of water containing salt, which is important in
countries with high salt content water resources.
Advantages of plastic mulching
1. It is completely impermeable to water.
2. It prevents the direct evaporation of moisture from the soil and thus limits the water
losses and conserves moisture.
3. By evaporation suppression, it prevents the rise of water containing salts.
4. Mulch can facilitate fertilizer placement and reduce the loss of plant nutrients through leaching.
5. Mulches can also provide a barrier to soil pathogens
6. Opaque mulches prevent germination of annual weeds from receiving light
7. Reflective mulches will repel certain insects
8. Mulches maintain a warm temperature even during nighttime which enables seeds to germinate quickly and for young plants to rapidly establish a strong root growth system.
9. Synthetic mulches play a major role in the soil solarisation process.
10. Mulches develop a microclimatic underside of the sheet, which is higher in carbon-di-oxide due to the higher level of microbial activity.
11. Under mulch, the soil structure is maintained during the cropping period
12. Early germination almost 2-3 days.
13. Better nodulation in crops like Groundnut.
14. Fewer nematodes population.
15. Water erosion is completely averted since the soil is completely covered from bearing the action of raindrops.
16. When compared to organic mulches, it serves for a longer period.
It is definitely correct that Organic mulching is more beneficial relative to plastic mulch, as organic mulch adds nutrient to the soil in the form of organic matter decomposition, improve soil water balance and reduce excessive temperature in the soil
organic mulches (Newspapers, straw, corn husks, dried manure, peanut shells, and compost) work well for mulch. Get creative and you might be able to save some money and the environment.
I prefer Organic mulch for its positive effects on soil microorganisms and a clean environment.
Organic mulch is made from biodegradable materials such as grass clippings, wood chips, dried leaves, and straws. On the other hand, inorganic mulch is comprised of river rock, stone, or crushed gravel.
The polyethylene film is usually a sheet of black plastic and it works the same way as organic mulch, the film insulates the soil, prevents soil erosion, and reduces moisture evaporation. While plastic mulching certainly has its benefits, it’s important to dispose of the mulching material properly to reduce its effects on the environment. The fact is, the use of plastic films as mulch material raises environmental concerns because plastic is a type of petroleum product. Apart from utilizing a lot of energy to make plastic materials, these are difficult to recycle too.
The functions while using plastic or organic mulching in the agricultural field are more or less same. Both of these retain/preserve soil moisture in the soil, conserve soil properties, prevent growth of weed, utilize the heat of sunshine properly etc. But in the context of environment organic mulching is more beneficial.
In my view, organic mulching is more beneficial. It is environmentally friendly as it enhance organic matter in the soil while serving its purpose (soil and moisture protection). Moreover, it facilitates water percolation into the ground during rainfall.
Both of them can retain/preserve soil moisture. However, Organic mulching is more beneficial relative to plastic mulch. It adds soil nutrient to the soil, improve soil water balance etc. In addition to that organic mulching also environmentally friendly or eco-friendly than plastic mulching. Currently, Plastics (microplastics, Nano plastics, etc.) are one of the new emerging environmental pollutants of the world.

I agree with Ababo Workineh that while organic mulches provide all the benefits, we must keep in mind that plastic mulches constitute an important source of soil pollution. We should practise mulching keeping in mind the long-terms effects rather than short-term benefits and ease of doing mulching.
Mulchings are used for controlling weeds as well as to conserve moisture. Plastic mulch are expensive but can be used for at least for two years without lifting it after use, where as organic mulches are cheap and also adds organic matter to the soil which is beneficial to the crop but it also depends upon its availability.
Thanks a lot Ali Alhayany , Kaushik Kumar Panigrahi , Abdul Aziz , Marco de Leonardis , Md. Abul Kalam Azad , Gonfa Kewessa , Ababo Workineh , Bijay Singh , Sunday Obazi , Shantonu Paul for your notable points.
Mulching has multifarious benefits. Uses of mulching materials totally depend on the purpose, for which particular mulching being to be used. For exam for controlling weeds like soil polarization, plastic mulching is a good option. In other cases for example for conserving soil moisture in grain crops, organic mulch is a good option.
I am totally in agreement with opinions stated by colleagues

Organic mulching has more benefits and advantages through its proper functioning in implementing a good cycle of returning more nutrients into the soil and a good turnover of soil microbial populations. During the years that I was studying in Germany I have seen that in everywhere they were using organic mulching in their gardens and agricultural fields.
Dear @Pankaj Yadav Organic mulching is better than plastic mulching as it is 100 percent biodegradable, and beneficial to both crop environment and the end users.
most of us says Organic mulch is effective but at the same time it has its own limitations as follows
Over-mulching can create an anaerobic (low or no oxygen) environment that allows fungal diseases to develop in plant stems and roots (some are toxic to humans).
Mulching at the too early in the spring can create water logged soils that may kill drought tolerant plants.
Mulch applied too deeply in the fall can create a home for rodents which may feed on plant stems and trunks throughout the winter. Pull mulch away a few inches from the trunks of trees and shrubs.
Roots may grow into the mulch and not the soil.
Slugs and other insects may colonize thick mulch.
Thick layers of sawdust and grass clippings compact easily and may prevent water from penetrating the soil.
we can use any type of mulch weather it is Organic or inorganic we need to understand the Conditions of the soils and Crops which we use but in Economic manner Organic is the best way but need to take care
Coming to limitations of Plastic Mulch
if the plastic cover brittle Small plastic bits will be left out in filed
Plastic is not that much economical when compare with organic farm residues mulch
Inorganic mulches do not provide nutrients to plants (Quite opposite in Organic mulch )
So Overall its all about Soil conditions and Availability of Organic mulch.
Hope this explanations are fulfill the above question
