The effects of inorganic fertilizers on farmlands
Updated: Aug 13, 2022
Inorganic fertilizers and chemicals plays a vital role in agriculture. Despite the fact that they are very important they still have several disadvantages. Carrying out a survey in agriculture, inorganic fertilizers and chemicals were produced to boost productivity in order to satisfy the alarming population in the world. But as time changes, inorganic fertilizers and chemicals as now become a treat to the environment and human population as a whole. Below are some effects of inorganic fertilizers and chemicals reactions farmlands.

Positive effects of inorganic fertilizers on farmlands
· Lower Cost: Inorganic fertilizers are massly produce, they are less costly than organic fertilizers which carries a significant higher expenses. They are cost-efficient for home gardeners because they provide complete nutrient and doesn't need continuous application.
· Fast acting: One advantage of inorganic fertilizers and chemicals s that they are very fast in action. That is they don't need a certain time to be broken down and decompose before usage because they contain nutrient that can be readily absorbed by plants.
· Convenient to use: It takes a while to prepare your own organic fertilizers. Though the process is relatively easy to do still, you need to delegate enough time to do the task and wait for the decomposition to take place. With inorganic fertilizers, you save time and energy and inorganic fertilizers are quite cheap and easier to use
· Contain all necessary nutrient that are ready to be used: Inorganic fertilizers contains minerals like potassium, phosphorus, nitrogen that are highly needed by plants to do well. Hence, plant don't get more than one kind of nutrient than the other instead it has a balance of all the nutrient it needs and are readily available at any time or at a given period of time.
Negative Effect of Inorganic Fertilizers on Farmlands.
Continuous cultivation of the land has various effect on the soil properties. It has been established that continuous and improper use of inorganic fertilizers and chemicals alone for intensive crop productivity can lead to soil degradation, environmental pollution, accumulation f toxic chemicals in water bodies and can cause severe environmental problem and loss of biodiversity. These points will be elaborated in the subsequent paragraph below.
· Soil degradation: With the overuse of chemicals and inorganic Fertilizers, the acidity of the soil will eventually increased and the soil will crust thereby reducing the organic matter, humus content, grows pest, alternate the PH of the soil and can eventually lead to the release of green gases.
· Destruction of soil physical characteristics: For physical it makes the soil to be loose and friable; for chemical, fertilizers may react or change the other chemicals compound of the soil to become toxic and these may affect microbial population and their activities there by reducing soil diversity.
· Accumulation of toxic chemicals in the water bodies: When chemicals and inorganic Fertilizers enters surface water, the nutrient they release stimulates microorganisms growth. The growth of these organisms may reduce the oxygen content found in the water there by limiting oxgyen to freely dissolve in the water which might lead to the dead of aquatic animals. · Cause air, water and soil pollution through nutrient leaching: When we water our crops, leaching is likely to occur and when rain falls leaching occurs and these chemicals are cried to the nearby streams and river which contaminates the streams endangering the health of man and aquatic animals .Fertilizers make the soil very loose and friable which are liable to soil and water erosion and even Leaching. When any of these processes occur, it is likely to live behind properties of ion and alluminion creating a hard pan on the soil.
Conclusion
As an organization, we want to ensure farmers don't only make profits but farm using Sustainable farming practices so as to protect our water-bodies and to improve the soil-structure and also boost the soil's water-holding capacity by using organic fertilizer.
Organic fertilizers are fertilizers gotten from a living source, such as a plant or animal.
