"ORGANIC FERTILIZER" a Source Conditioner In Modern Agriculture

Updated: Jun 3, 2021

We could see that organic residues have long been used as a technique of preserving and improving soil fertility. But, since the introduction of low-cost mineral fertilizers, this tradition has been partly abandoned. There is increasing interest among farmers and scientists in the proper and efficient use of organic leftovers, composts, and other recycled organic additives. Also in recent years, the role and function of organic amendments in modern agricultural systems have aroused the scientific and agricultural communities.

We can see the trend toward energy conservation which has prompted scientists to investigate the minimal tillage system, as well as ways to replace conventional inorganic fertilizers with natural organic products or microbial preparations, and to develop new composting methods as well. The desire to increase yields in commercial greenhouse farming has resulted in the search for optimal substrates as growth media and also improved management techniques. This has resulted in the introduction of organic substitutes, particularly those derived from agricultural waste. Another significant factor is the current interest in organic farming, which avoids or prohibits the use of synthetic chemicals. Willingness to pay a premium for food grown on soils, free of inorganic fertilizers and other agricultural chemicals in the growing proportion of the population in developed countries.

Source of organic fertilizer

We know that the main organic fertilizers were derived from peat, animal wastes, agricultural plant wastes, and sewage sludge. Animal waste from meat processing, peat, and slurry are examples of naturally occurring organic fertilizers. Organic fertilizers are carbon-based compounds that improve plant productivity and growth quality. Organics which include manures, powdered rocks, blood meal, bone meal, wood ash, and compost all contain important micronutrients, and their texture is helpful in improving soil quality. Now a days organic farmer's emphasis on using only organic fertilizers for the soil unchanged.

Organic farming was seen as a way of life in many ways, as it is a farming method. We could see that Soil nutrient depletion and potential deterioration have been highlighted as key contributors to lower crop yields and per capita food supply, as well as substantial risks to agricultural productivity.

Organic farming not only benefits the environment and food quality, but also assists farmers in becoming self-sufficient in their agro-input needs and lowering their prices. Organic farming aims to achieve a balanced blend of organic, environmental, social, and ethical goals.

Importance Of Organic Fertilizer

Organic fertilizers were differed from chemical fertilizers in a way where the components were derived from plants, animals, or minerals. These sources are decaying matter which would naturally decompose and contribute nutrients and minerals to the soil. But when it came to lawn care, one could not ensure that the lawn or garden received all of the nutrients it required to thrive. Although nutrients were present in typical soil, fertilizers can offer and ensure that the plant had a balance and appropriate access to nutrients. related more slowly than they were with artificial fertilizers.

This slower process allows the plant to process the fertilizer in a more natural way and will not result in over fertilizing which could damage the plant. Groundwater pollution is concerned it is caused by synthetic fertilizers and pesticides in many agricultural areas. Organic fertilizers helps in improve soil structure and water infiltration by utilizing more biodiversity and so groundwater pollution is considerably reduced by well-managed organic systems with superior nutrient retentive properties.

Impacts of organic fertilizer & Application on soil properties

The decreases in soil organic matter content owing to cultivation and erosion have been a key source of concern for agriculture's long-term viability. As a result, we can see soil quality and production were assessed to benefit from management approaches that increased organic matter content. Furthermore, regular applications of solid cattle manure increase soil organic matter. The impact of manure on the pH of the soil seems to be variable. The content of organic matter was an essential indicator of soil quality and fertility. Organic matter is one of three soil components that are essential for its physicochemical properties, including its athletic and buffering abilities, as well as biodiversity and biological activity. Because organic matter has such a positive impact on soil functionality, it was critical that its resources be preserved or improved. It is seen that farmyard manure has long been known to improve soil structure, increase porosity and water holding capacity, and reduce evaporation rates. It has also been reported that applying cattle feed manure to soils increased water infiltration while decreasing crust strength. The Improvements in physical soil quality characteristics were generally indicated by increases in water infiltration, macroporosity, aggregate size and stability, and soil OM.

I would like to conclude that organic and synthetic fertilizers have had an impact on soil qualities and agriculture, and the benefits of both should be recognized. on the other hand, Synthetic fertilizer had more drawbacks than organic fertilizer especially in modern agriculture. Organic fertilizers are those that are made from animal, human, or vegetable matter (compost, manure). The other major advantage is that bulk of organic fertilisers can be made on the farm or locally. The use of these organic fertilizers guarantees that the food produced is free of harmful chemicals. In order to conserve soil qualities and boost soil production, it is advised that organic fertilizer (or) a combination of biofertilizers be used instead of artificial fertilizers.
