If the fertilizer is not given in sufficient quantity, it will affect the productivity of the crop. In this case, organic matter is organic fertilizer. The algae grow out of control and cover the top of bodies of water, this produces toxic effects on people, fish, and birds. Studies say that it results from feeding infants with baby formula usingnitrate-contaminatedwater. Chemical fertilizers can be categorized into two types, namely organic and chemical. High taxes on tobacco and drink reduce average and usually also excessive consumption. Nutrient cycles become more efficient, as the biodiversity of birds, plants, arthropods, and micro-organisms are increased. In such a situation, the introduction of excise on synthetic nitrogen fertilizer and other chemicals used to maximise crop yield, can be one of the tools to discourage the use of such fertilisers and at the same time promote and the use of more environment friendly, non-chemical fertilisers and other farming alternatives. According to a report on climate change, in 2008 the emissions for the agriculture sector are projected to be 77 Mt CO2 of emission over the Kyoto period.

Some popular organic fertilizers include bone meal, blood meal, feathers, fish emulsion, burned eggshells, and urea (urine) (Penhallegon, 2015). As discussed earlier, because of the low price elasticity of demand, the fertiliser manufacturers will be able to pass on most of the tax burden to the farmers in the form of higher price. CC By 4.0, Ecampus Ontario. A 1973 study links high levels of sodium nitrate in groundwater with gastric cancer. This can result in local level of water tables. The damages that fertilisers have on the environment can be divided into three broad categories; natural resources (water, soil and air), wildlife and ecosystem and human health. Pesticide exposure, for instance, can cause adverse health effects on humans, especially unsafe pesticide levels. Specific or volumetric taxation is based upon the number of units sold, irrespective of their value and recognises that the potential for harm falls equally upon consumers or the community irrespective of the price of the item.

With proper legislation and public participation, we will be more aware of how our plantations are being fed. However, once the excise model for the N nitrogen is established, a similar model can be used to impose excise on all the other fertilisers. Composted Manure- This is the complete fertilizer, but the NPK ratio depends on what animal it is derived from, it is very high in fresh manures which is good, the only downfall is that it is the most expensive.
The Health Impacts of Chemical Fertilizers | Amos Institute Blog The design and makeup of the natural world is an amazingly unfathomable. The results showed that in Denver, assuming a concentration of 10,000 plants per cultivation facility, cannabis could more than double the existing rate of annual VOC emissions to 520 metric tons and produce 2,100 metric tons of ozone. Pesticides benefit the crops; however, they also impose a serious negative impact on the environment. The next issue in the rate setting process is to determine if this rate is going to be specific or ad valorem. Excise tax can be used as one of the tools for the government to influence the agriculture industry and influence the level of demand for synthetic nitrogen fertilizer. Maybe thats because chemical fertilizers are not the only chemicals from the agricultural sector that is controversial for its burdens on the environment and human health. Under the self assessment system, businesses keep records and fill out their own excise return. Vizuete believes his estimates might be conservative, explaining, "We picked four [cannabis] strains based . Microbes feed off of carbon in soil and plant roots will even put out carbon compounds (exudates) to attract them. A US study estimates the externalised costs of agricultural production (in natural resources, wildlife, biodiversity and human health) to be between $5.7 and $16.9 billion annually is a broad estimate, it is not Australian-specific, nor restricted specifically to agriculture, but it does highlight the need to understand the environmental impacts of agriculture better in the Australian context.
