Fertilizers remove the nutrients of the soil damaging the soil and the local environment and after being mixed with the soil, gradually reduce the fertility of the soil. In the study of (Southland) using fertilizers consists of substances and chemicals like methane, carbon dioxide, ammonia, and nitrogen, the emission of which has contributed to a great extent in the quantity of greenhouse gases present in the environment. These facts are alarming and a serious step needs to be taken as soon as possible to avoid more severe consequences. This in turn is leading to global warming and weather changes. The use of fertilizers for growth and cultivation is keeping our stomach filled for now, but then if things keep on progressing the way they are, it won’t take long to see the times where there is lack of food, water, and health.

The answers to these questions are all within the realm of science because they are testable by controlled experiments, observations and data gathering. Hypothesis If fertilizer is added to different types of seeds, then seed germination will become faster. Materials For this experiment we used the following items; a Ruler, Fish Fertilizer, Miracle Grow, Water, (3)150ml Plastic Containers, a Dropper, a Karter Scientific Pipette, (3) Plastic Plant Pot Trays, Potting Soil, Oregano seeds, Wheat Cat Grass seeds, and a Spread Sheet. Variables Our constant (the variable that is never changed) in this experiment was the potting soil. Our independent variable (the variable that is being changed or controlled) is the different types of fertilizer.
These processes are usually wet to enable material transport and to reduce dust. Phosphate rock is THEN mixed with sulphuric acid to produce weak phosphoric acid. This phosphoric acid is mixed with various other minerals to produce liquid or solid fertilizers. Theses process vary with respect to the fertilizer being produced. Frequently manufactured fertilizers are triple superphosphates (SSP, TSP) and ammonium phosphates (MAP, DAP).
This fertilizer has a more long term effect, the fertilizer improves the structure of the soil which makes it easier to hold water and the nutrients it needs to be a long lasting plant(A comparison between). There are not any toxic chemicals that can kill your plant and you can never add too much fertilizer, because there are no toxic buildups. This natural fertilizer is great for our environment, it is renewable and biodegradable, this means we can always have a large supply of the fertilizer. There are also downfalls to go with the natural
Soils can be improved but also degraded through fertilization. The choice of the proper kind of fertilizer and the rate of application are very important issues for crop growth and the environment. It was also found that decreases in profit can be due to either over- or under the recommendation of N fertilization (Bullock and Bullock, 1994). Conventional practices can sometimes result in sizeable fertilizer N losses, especially in extremely wet springs in the Corn Belt (Mathesius and Luce, 2009). In fact, only 30 to 50% of applied N is recovered by the crop in many cases (Raun and Johnson, 1999).
Sulfur in the soil is generally in a sulphate form, and microbes change it to sulphide compounds that enter the soil solution and can be taken up by plant roots for growth. This image here shows the sulphur deficiency (left) and Sulphur filled plant
These is sufficient ammonia present of suppress nitrogen fixation. Important: in terms of generate nitrogen available to all organisms, the symbiotic associations very much exceed the free-living species with the exception of cyanobacteria. The world's growing population, depends ultimately on plants for food.They in turn depend on supply of nutrients, especially nitrogen compounds, in the soil. In world agriculture today, the natural processes for replenishing nitrogen used up by crops are too slow to sustain the productivity needed, and the shortfall is made up by chemical fertilizers, prepared industrially by taking nitrogen from the atmosphere, the Haber process. A few type of bacteria, collectively called, diazotrophs (di = two, azo = nitrogen, troph = feeder}, can use nitrogen from the atmosphere, but plants can not.
This change has many effects that can appear through the reduction of chemical and physical qualities of the soil resources. FAO (1993) further stressed that soil degradation is the sum of geological, climatic, biological and human factors which lead to the degradation of the physical, chemical
