However, the structure of agrichemically-deadened soils is weakened by the corresponding loss of soil life and thus unable to maintain its integrity under occasional cultivation. So it’s a circular argument! Structurally sound (life-rich) soils may be cultivated regularly without significant damage, particularly if protected appropriately by windbreaks and Keyline soil conservation
Mainly through mechanical compression, and this leads to a decrease or total elimination of air pores. Soil compaction may lead to run off and erosion since it reduces soil water permeability is therefore undesirable in agricultural production. Soil strength
Introduction Aim: To compare the effectiveness of compost and earthworms on the germination and yield of a spinach crop. Motivation: Fertilisers are mixture of chemicals that add nutrients to the soil to establish better yielding crops (Berger, 2013). Though these products have proved to provide many beneficial aspects to the agricultural sector, they have many negative environmental consequences. Fertilisers contain many substances, including mostly potassium, phosphorus, sulphur, calcium, magnesium and nitrogen. These substances, when they accumulate in the soil, can have harmful side effects on the environment and subsequently on the productivity of crops (Vimpany and Lines-Kelly, 2004).
Soil erosion happens more frequently on a larger scale when there is little vegetation on land. Plants shield the rainfall impact and splash, thus letting the water spread slowly into the soil and reducing the rainfall impact. The plant type is crucial in order to have the least amount of soil erosion. Plants that have fibrous root are known to be one of the best kinds to reduce soil erosion such as the grass. During a rainfall, soil erosion is evident and is concerned more.
This is done to ensure that the soil where the plant is to planted in have complete chemical components to ensure a normal growth and life cycle. Mineralization of carbon and nitrogen in soil are caused by soil organisms that eat organic matter (Meister,
The effects caused by overcropping can be lowered through the use of organic manure, i.e cattle dung, to the soil through irrigation. However, in areas such as the Sahel, deforestation is also happening in some of the areas suffering from soil erosion. This means that people are using cow dung for fuel instead of as an organic fertiliser. This means that there is no cattle dung to fertilise the land. Aspect 3: The effect desertification has on soils.
From the look of things, I have found that these impacts cause more harm than good. If the water cycle is disturbed, my farming processes will be negatively affected. The first effect is that, the washing away of a fertile top soil would lead to a poor harvest, since all the required nutrients for the crops to grow would be washed away. The loss of fertile soil can lead to an increase in the cost of production due to the use of inorganic fertilizer. The other effect is that, if the water cycle is disturbed, the amount of rainfall per season will be affected which will also affect agricultural production since the processes of the water cycle have been disturbed.
When these nutrients are taken away this can lead to the soil lacking the micro nutrients that are needed. Nitrogen is available abundantly because 78% of the air is made up of nitrogen. Potassium comes in small portions, but it is also available abundantly. The fertilizer that the neighbor is using whether it is synthetic or natural has severe consequences when it is continually applied to the grass. There is a depletions of nutrient sources and a depletion can occur in his soil.
Land pollution causes the land’s productivity and potential to decline to such a level that the purpose of utilising lands for building infrastructures, housings, services, agriculture, forestry and many more for the development of human being are no longer achievable (Prabhakar, 2012). Land pollution are resulted by some sources which are deforestation, mining and construction activities. Deforestation appears to be the major concern as once the land is converted into dry lands, it can hardly be made fertile again. Those areas inevitably end up as waste lands. Mining requires the removal of topsoil containing valuable organic matters.
LITERATURE REVIEW Inorganic fertilizers provide rapid nutrition and give plants with the nutrients needed to grow healthy and strong. Inorganic fertilizer, also called as synthetic fertilizer, is manufactured artificially and contains minerals or synthetic chemicals and it is which help a plant to grow faster. Effective use of Inorganic Fertilizers Effectiveness in using these chemicals has good and bad effects on the environment especially on the health of a human being. Fertilizer has turn into essential to modern agriculture to feed the growing population. Use of fertilizers, especially, the chemical fertilizers has brought in blessings on humanity, which helped contain hunger and death in changed corners of the world.
