All the initiatives launched within the framework of the EU are aimed at promoting a more sustainable agriculture. About to start the nitrogen fertilization campaign for winter cereals and rapeseed, Fertiberia makes a series of recommendations for sustainable nitrogen fertilization.
Not all the products found on the market have the same fertilizing power, nor the same concentrations nor the same environmental traceability. For this reason, it is essential that before investing in plant nutrition solutions, the Datasheet of the product. To interpret it, we must know that a nitrogenous fertilizer can have three chemical formsunique or combined with each other: ureic or amide, ammoniacal and nitric.
He nitrogen in urea form It presents as its main characteristic that it cannot be directly assimilated by the crop, so it needs a transformation to become ammoniacal nitrogen and this is conditioned by the temperature and humidity present in the soil. In certain areas we can have humidity in the months of application of coverts, from January to March, but almost in all probability we will not have a temperature for this transformation to be done properly, which causes losses of nitrogen in the form of ammonia gas between 15-50%.
However the nitrogen in ammoniacal form It remains fixed in the clays of the soil and has hardly any losses, so the crop will gradually absorb it as it transforms into nitric form.
For his part, he nitrogen in nitric form Nitrogen is the majority and most rapidly absorbed by crops, this being the most efficient form per unit of nitrogen supplied.
In addition to being more efficient, profitable and sustainable in the coverts from Laziness remember that they exist strategies such as: divide them into several applications if the crop allows it, use nitrogenous containing nitric forms or apply nitric forms accompanied by sulfur, which gives the fertilizer more efficiency in addition to completing the fertilization with another necessary element, being optimal for use in early coverts and also in the late
