Introduction:
N cycle
Transformation of ammonium in the soil
DMPP retards the naturally occurring transformation of ammonium (NH4) via nitrite into nitrate (NO3) by selectively inhibiting the activity of nitrifying bacteria (Nitrosomonas) over a period of 4 to 10 weeks
Advantages of the use of fertilizers with the nitrification inhibitor DMPP
ð Reduction of the risk of nitrate leaching
ð Reduction of the risk of N2O emission
ð Partial ammonium nutrition of the fertilized plants
ð Frequently yield increases or savings of fertilizer N
ð Reduction of the number of fertilizer applications (simpler fertilizer application strategy)
ð Frequently improved crop quality (e.g. nitrate content of vegetables, leaf colour)
ð Easily incorporated into granular fertilizers
ð No environmental concerns

gabriel he visto en homo que gastas entec21 ¿que vale el saco?, y yo que suelo utilizar bastante el amoniaco en calabacin ¿el entec me iria mejor? el abonado que echo siempre es de 2kg potasico y 1kg de amoniaco, bueno y calcio cuando ya estoy en kilos. ahora para invierno hay que tener cuidado con las pudriciones y mas en invernadero plano.
ResponderEliminarNo tengo interés en hacer publicidad, pero si, lo uso, lo uso en invierno en vez de sulfato amónico, no sale caro, si más caro que el sulfato amónico normal, por eso solo lo uso en invierno. Enternece menos y en suelo los amonios no me importan la planta los utiliza más de lo que se suele creer.
ResponderEliminarEl post es referente al inhibidor de la nitrificación que lleva el entec.
