After 20 years of application of these biofertilizers by the farmers in more than 35 countries and the results obtained in trials which aim was to find out a comparison in terms of plant nutrition effectiveness between the biofertilizers of INAGROSA and the standard formulations of chemical fertilizers, we have summarized the different figures obtained, according the wide different conditions of soils, climate, rainfall, etc…in the following average figures.
The comparison is made only in terms of cost in USD/hectare and in nutrition effectiveness (Weight of yield) on crops, in which were carried out the treatments:
T1: only chemical fertilizers (urea, DAP, Potassium Nitrate, etc…), one compound per treatment.
T2: only INAGROSA biofertilizers, only one per treatment.
T3: control, without any fertilization.
A) In terms of Nutritional Effectiveness.
1 L/ha of FOSNUTREN <> 210 Kg DAP /ha
1 L/ha of KADOSTIM <> 225 Kg of Potassium Nit./ha
1 L/ha of HUMIFORTE <> 102 Kg of Urea /ha
1 L/ha of HUMIFORTE <> 140 Kg of 12-12-24 /ha
Physical Effectiveness:
a) Chemical fertilizers, according the technical literature, only 30-35% of the quantity spread on the soil reach: the root system, from this percentage only 50% reach the cells.
b) Biofertilizers, around 90% of the liquid sprayed on the crops reachs the leaves (stomata) or cuticle from this percentage, 100% reachs the cells.
B) In terms of cost (at current prices July 2009):
