Organic Fertilizer

Though agricultural revolution has led to unbelievable yields and crop productions but the means which have derived all these increments seem to hamper the fertility of soil.
The harsh chemical have started registering their harmful side effects on the soils. Today what each farmer is looking forward to is a proper solution to the agricultural problems without compromising on the yields.

It is an universally acknowledged fact that organic fertilization methods are more environmental friendly and fetch slower but steady results. Today when the world is advancing so fast in every aspect, how can the life supporting area can be ignored? Today the use of fertilizers is one of the greatest innovations of the agricultural revolution.

 

What is Organic Fertilizer?
Organic fertilizers are naturally occurring fertilizers and nutrient enhancers of the soil. Therefore every substance that occurs naturally and is easily bio-degradable is organic and if this organic material enhances the richness of the soil, it is termed as organic fertilizer.

Naturally occurring organic fertilizers
It includes animal manure, slurry waste, peat, seaweeds, sewage, guano waste and other bio-degradable wastes. Mine rock phosphate, sulphate, potash and limestone also fall under the same category. Decomposing crops also make up for a naturally occurring organic fertilizers.

 

Manure: The organic waste of animals is termed as manure when it gets decomposed by the ongoing process of bacteria and fungi. this decomposed matter called manure is then used in agriculture to enhance and promote productivity of soil and thus revolutionize the yields.

Slurry waste: Scientifically it is a thick blend of solids in any liquid and when talking about agricultural slurry it has to be any house or animal waste material well blended with water to inculcate soil fertility. It is prepared through a long term process of collecting the waste material in a huge container or tanks and then transported to the agricultural fields in the similar liquid form. It is in liquid form, therefore it gets dissolved easily and mixes well with the soil which leads to nutrition of soil.

Worm Castings: It is also referred to as by different names such as vermicompost, worm compost, worm humus, etc. It is the end product of anything that is resulted after the break-down of any organic material or waste by the worms, insects or earthworms. It is highly rich in nutrients and proves to be a worthy soil conditioner.

 

Manufactured organic fertilizers
The fertilizers which are manufactured by decomposition of natural waste material are termed as manufactured organic fertilizers. Compost, blood meal, bone meal and sea weed extracts.

Compost: Also called as Brown manure, it is the end product of the decomposition of the organically waste material. It is a process which is carried on by numerous bacteria, fungi and other little organisms. Used in landscaping, horticulture, and to prevent soil erosion, compost is an effective solution to soil troubles.

Bloodmeal: It is a nitrogenous fertilizers which is made of dried powdered blood. Highly soluble mixture it can easily be taken in by the soil and it is a huge storehouse of ammonia and other nitrogenous elements. After being mixed with water, it can be used as a liquid fertilizer. It can also be sprayed in garden as a animal and insects deterrent.
Bone meal: As the name suggests, bone meal is a crude mixture of crushed and powdered bones. It works effectively as a slow source of nutrients which keeps on supplying the essential nutrients at equal intervals. It is a great source of phosphorous.
 

Advantages of Organic Fertilizers
Fertilizers enhance the richness of the soil and nourishes it with required nutrients.
By enriching the soil, fertilizers also increase the productivity of the crops. Fertilizers are the nutrient filled sources which nourish the plants with essential nutrients and soil acts as a medium between the crops and the fertilizers.

The organic humus registers a very important role in the soil nourishment. It mobilizes the existing soil nutrients and enable them to reach the plants in equal and balanced quantities.


The nutrients are released at a slower speed which implies that the plant are not suffixed to pressurized growth but their natural capability is enhanced to a greater extent . This ensures safety of plants and lessened toxic levels in the plants.

Organic fertilizers retain a blanket like cover on the soil thus enabling it to recapture the moisture level and not let it out. Thus it also helps to recover the stress levels of the soil by maintaining its moisture content.

The organic fertilizers help to sophisticate the soil structure by nourishing it, enhancing its productivity and at the same time protecting it from being eroded away.

How organic Fertilizers are better than Inorganic fertilizers?

Artificial and inorganic fertilizers have certain disadvantages as they have to be applied again and again. they become a necessity to the soil or else the productivity is hampered.
They act as a drug for the soils as till the time the soils are fertilized they remain productive or else they die down.

Eutrophication, nutrient pollution is caused due to extra application of the artificial fertilizers.
