Ácidos Húmicos  

CULTIVOS AL AIRE LIBRE

PAPAS
Crecimiento de rendimiento de cultivos de papas después de la aplicación de Powhumus (Egipto). Después de la aplicación de 6 kg/ha de Powhumus el rendimiento aumentaba de 900g a 1.200g por planta. El tamaño promedio de las papas aumentaba también. Papas de un tamaño grande o mediano preponderaban a papas pequeñas.  (Foto 1,2)

FRESAS
Crecimiento aumentado de los brotes y de las raíces en cultivos de fresas después de la aplicación de Powhumus (Alemania). La adición de 4 kg/ha de Powhumus a cultivos de fresas directamente después de su cultivo en invernaderos provocaba un crecimiento elevado de los brotes y de las raíces. Además el peso seco de las plantas aumentaba lo que prueba la absorción elevada de nutrientes. (Foto 3,4)


ONION
Also onion were grown with POWHUMUS®. In the trial were incorporated 3 and 6 kg/ha Powhumus® into the soil. The fertilization was performed as usual accordance with good practice. Higher yields were measured up to 17%. The quality of the crop were improved as well. The percentage of marketable crop on the total harvest increased significantly as well. (s. Fig. 2)


SUGAR BEET
When growing the sugar beets were very achieved in need-based mineral fertilization and the use of POWHUMUS® good earnings growth. In the application of 6 kg per hectare POWHUMUS® shows an increase in yield of up to 21%, based on the sugar yield, are achieved. (s. Fig. 3)


CORN

In a number of trials Corn were incorporated with 6 kg/ha into the soil. The fertilization was performed as usual accordance with good practice. Higher grain yields were measured up to 14,7% compared to control.(s. Fig. 4)


STRAWBERRIES

Increased shoot and root growth at strawberry cultures after Powhumus application (Germany)
The addition of 4 kg/ha Powhumus to strawberry cultures directly after their cultivation in greenhouses caused a strong growth of the shoots and the roots. Also the dry weight of the plants increased as a proof of the increased nutrient uptake. (Pic.3,4)

Basil (Ocimum basilicum)
Study of the Agriculture Faculty, University of Mashhad (Iran):
The results of this study showed that application of humic acid on growth and yield parameters was effective. Application of humic acid with concentration H4(15g/l for 0.5m) have the best of growth and yield but was observed the highest of height of plant in H2 (5g/ l for 0.5m). (Pic.5,6)  

Increased yield of Wheat (Triticum aestivum) by 24%, through the positive impact of the application of 15 kg/ha of Powhumus on soil water holding capacity.
Location: Comuna de Teodoro Schmidt (38°59` S; 73°05` W), Region of Araucanía, Chile.
Soil texture: loam - clay loam.
