chemical fertilizer leads to a loss of organic humus, a deterioration of the fertility of top soil and a decrease in porosity the roots do not get oxygen and cannot absorb the salts effectively......
The benefits, if properly applied according to instructions, is an improvement in plant growth and yield.
The risks are if the instructions are not followed, are damage to the plant roots or general well being, possibly leading to plant death.
Yes, fertilizer can be hazardous.
Specifically, fertilizer can be hazardous when it is applied too often and in excess. Excess applications end up achieving the opposite of what is intended: soil and soil food web depletion instead of fertile soils teeming with subterranean air, life, moisture and nutrients. The excess nutrients run off in such a compacted, hostile environment and pollute area water bodies.
Fertilizer (and pesticide) contaminates water draining from: * Golf courses * Farms * Urban and suburban residential areas * Fertilizer and pesticide manufacturing, sales and transfer sites
Fertilizer is a concern of farms and agriculture. Therefore, the Department of Agriculture would be concerned with this. The Environmental Protection Agency would be concerned with fertilizer runoff and possible toxicity or pollution due to certain fertilizers.
Eutrophication
They provide increased yield on the fields where they are used - more than enough to compensate for the cost of the fertilizer. The environmental damage occurs downstream from the farms from the effects of the fertilizer in the runoff water.
it is polluting our lakes and rivers
nonpoint source pollution
The pollution caused by farms can be broaken down by the medium it pollutes:Air:* Odours * Ammonia * Dusts Water:* Runoff containing * ** Fertilizer ** Pesticides ** fecal matter ** Ammonia ** Silt ** Nitrates/Nitrites * Groundwater containing * ** Nutrients ** Pesticides ** Hydrocarbon (fuel) Solid Waste:* Animal manure * Dead animals * Fertilizer etc.Bags * Twines * Equipment * Used tires
If you touch you drum set i will stab you in the neck with a knife!
salinity
it comes from the fertilizer.
Pond, because the water is stagnant.
Chemical runoff in an agricultural context is when farming chemicals, such as fertilizer are not absorbed into the topsoil. When a heavy rain comes, these chemicals are caught in the storm water runoff and make their way into streams, rivers, and lakes.
