This is a very complicated question. Many factors apply in how much fertilizer to apply to a field of any crop, wheat included. You must know the type of soil, how much nutrients are still remaining from the previous crop, and how much of a yield you expect to get from the crop. The best way to find this information is with a comprehensive soil test. See the related link below for a full chart which shows how much of all the main nutrients are needed for corn, soybeans, and wheat, both grain only and if the stover (residue) is removed. Even when you have all this information, the farmer has to decide at what levels of productivity his farm is running on the most economically efficient level.
depends entirely on the type and concentration of the fertiliser you are using
too much water too little water too much fertiliser not enough fertiliser herbicides amongst other methods
It depends what type of fertiliser. for example chemical. it will help seeds growth, but too much will burn the plant. But usually fertiliser does increase seeds growth. Just not too much of it. It is a fact that chemical fertiliser is less healthy than organic fertiliser. Hopt this helps :)
they needed to trade the wheat
199 mm per year
If you mean "Wheat Penny's" be more specific, dates are needed.
Fertilisers increase crop yields but cause the problem of eutrophication when they're ... However, if too much fertiliser is used it can pollute water supplies.
The average temperature needed to grow wheat is 17*c.
it dies
yes
refined wheat flour doesn't have any fiber content and fiber is very much needed for digestion. that is why Maidha is very difficult to digest though it is a wheat flour.
6.0 and above, the pH level effects the nutrient availability, so finding the right pH with what your soil has and doesn't have in terms of micro and macro nutrients changes what fertiliser you put on and how much.
